What is your opinion on Magnavox Flat panel Televisions?

First, they are not the best performing sets. But, you might be able to live with that. You should compare with Vizio and Olevia before you decide. But the bigger problem is that none of these lower tier sets are reliable, and even worse, they do not have a high probability of being repaired when they do fail. You may find yourself tossing it out in a year or two. Maybe you should consider a smaller set from a higher quality source like Sony, Panasonic, Etc.

Is this the beginning of the end as the UN climate change panel is officially warned over its reports?

traditionally as with the present one that has lasted approximately one hundred thirty years now heat sessions have much less sickness, extra efficient meals substances and becoming inhabitants stages and that seems to be retaining actual. on the different hand deep cooling sessions like the little ice age that ended interior the mid 1800s have intense well being concerns for anybody. The lead in to the little ice age delivered with it the black plague that devastated the inhabitants of Europe and the middle East as a results of fact superstitious persons that have been taught to affiliate cats with witches throughout the time of the catholic and puritan inquisitions had killed off a huge share of the cat inhabitants that would have stored them especially much rat loose. yet as a results of fact they killed lots of the cats the fleas from the plague rats killed them. Warming climate brings well being and prosperity to the international. Cooling climate brings sickness, starvation and barbarian invasions of northerners shifting south to locate warmer lands to develop meals on and stay in convenience on. worry extra chilly not slightly heat temperature!

Do you have to have a 200 amp electrical panel to have a hot tub, or will 100 amps be enough?

The question is a little hazy, and the the answer probably depends on the exact spa chosen. I think what you want you are indicating is that the house has only a 100 amp service, and you are concerned that the the house might not have enough power available to feed the hot tub. Hot tubs vary in the power requirements, you can choose one that plugs into a 120v 15 amp gfci outlet, or you can choose one that uses a dedicated 240v, 50 amp breaker. The 120 volt unit may not heat and pump at the same time, and may have size limitations. A 100A service can get a little too loaded up quickly if you have all electric appliances, lets imagine you are doing laundry, your electric hot water tank turns on, 24 amps, you put the clothes in the dryer on high heat, another 24 amps, it's time to start dinner, you turn on the stove, bake and preheat elements both on, 30 amps, one room in the house has a baseboard or recessed wall pack heater, another 10 amps, suddenly you are up to 84 amps without any lights, tvs, computers, microwave, fridge, freezer, hair dryer, or hot tub coming on just to maintain the heat. You probably wo not need all of this at once, but it is possible.

Does the solar panel have radiation or not?
Does the solar panel have radiation or not?
  Radiation refers to the outward diffusion of energy in the form of electromagnetic waves or particles (such as alpha particles, beta particles, etc.). All objects in nature, as long as the temperature is above zero absolute temperature, constantly transmit heat in the form of electromagnetic waves and particles. This way of transmitting energy is called radiation. The energy of radiation radiates in a straight line from the source in all directions. The energy emitted by an object through radiation is called radiant energy. The radiation is calculated according to Roentgen per hour (R). An important feature of radiation is that it is "equivalent". No matter whether the temperature of the object (gas) is high or low, the object A can radiate to the object B, and the object B can also radiate to A. Radiation energy is widely used in the fields of medical diagnosis, industry and biology for the benefit of mankind. However, all radiation is harmful to organisms and can affect the natural environment, among which the harm caused by ionizing radiation to human body is the most common. What kind of radiation is harmful to people?In a general sense, "radiation" refers to radiation that is harmful to human cells, such as those that cause cancer, which are highly likely to cause genetic mutations. Generally speaking, it includes short-wave radiation and some high-energy particle flow.Does the solar panel have radiation or not?Does the photovoltaic panel produce radiation? For photovoltaic power generation, the power generation mechanism of solar modules is completely direct energy conversion, in the visible light range of energy conversion, there are no other products generated in the process, so it will not produce additional harmful radiation.Solar inverters are only general power electronic products, although there are IGBT or Triode, and there are dozens of k switching frequency, but all inverters have metal shielded shell and comply with the global electromagnetic compatibility certification.   Does the solar panel have radiation or not?Photovoltaic solar panels do not produce radiation. However, light pollution caused by photovoltaic solar panels may have an impact on health.Photovoltaic solar power generation, the principle is that light energy is directly converted into electricity, the advantage is that solar energy is everywhere, can be nearby power supply, the disadvantage is that the price is still relatively expensive. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electric energy. The key component of this technology is solar cells. After the solar cells are connected in series, the solar cells can be encapsulated and protected to form a large area of solar cell modules. Flat solar cell modules are photovoltaic solar panels. Light pollution is a new environmental pollution source after waste gas, waste water, waste residue and noise pollution, mainly including bright pollution, artificial daylight pollution and color light pollution. Light pollution is threatening people's health. In daily life, the common light pollution is the dizziness of pedestrians and drivers caused by the reflection of mirror buildings, as well as the discomfort caused by unreasonable lighting at night. At present, there is no clear basis and conclusion on the impact of light pollution on health, let alone relevant evaluation criteria.   However, some studies suggest that light pollution has the possibility of damaging eyes, inducing disease and affecting people's mood. It is generally believed that light damage may cause headaches, fatigue, decreased sexual ability, increased stress and anxiety. Animal model studies have shown that when light is inevitable, it can adversely affect mood and anxiety. The light damage of photovoltaic solar panels can be easily avoided by selecting photovoltaic solar panels with low reflection, adjusting the reflection of photovoltaic solar panels to uninhabited areas, blocking the reflection, and wearing sunglasses for installation personnel.   How to solve the problem of light pollution 1. In order to reduce the harm of light pollution, the key lies in strengthening the management of urban planning, reasonably arranging light sources, strengthening the management of advertising lights and neon lights, prohibiting the use of high-power and strong light sources, and controlling the use of high-power civil laser devices. Measures such as restricting the use of materials with large reflection coefficient are imperative. As ordinary people, on the one hand, do not stay in the light pollution zone for a long time; if the light is too strong, the room can install blinds or double curtains to adjust accordingly according to the light intensity; on the other hand, the whole people should plant trees and flowers around the buildings. plant turf extensively to improve and adjust the lighting environment, and so on. 2. It is suggested that the state should formulate technical norms and corresponding laws and regulations related to light pollution. Few people in our country realize the harm of light pollution, so there is no unified standard in this respect at all. Experts believe that with the rapid development of urban night landscape construction in China, it is necessary to formulate technical standards for landscape lighting as soon as possible. Let's not take the detours that others have already taken. In addition, experts believe that it is also very important to strengthen the standardized management of night landscape design and construction. At present, there are few professional and technical personnel engaged in lighting design and construction in our country, and many night landscapes that produce light pollution and light interference are caused by unscientific design and construction. It is understood that Tianjin has promulgated the "Technical Specification for Urban Night scene Lighting", which is the first technical specification for night scene lighting in China. Beijing once had a "Evaluation Standard of Urban Night scene Lighting Project" in the construction of night scene, but there were only simple projects to measure light pollution. Experts appeal that the lack of science and standardization in the construction of urban night scenery needs to be changed urgently. 3. Vigorously promote the use of new energy-saving light sources. At this stage, although most places will consciously use energy-saving light source, but there are still most places can not achieve the conscious use of energy-saving light source lighting.
Solar Photovoltaic Street Lighting Systems
Solar photovoltaic street lighting system is a photovoltaic lighting system for solar street lights that work on photovoltaic cells or batteries, this solar street light system will convert sunlight or solar energy into electricity.     Types of solar PV systems   We all know PV systems are widely being used for solar applications over the past few years, and nowadays the scope of solar photovoltaic (PV) systems has grown exponentially. There are three main types of solar energy and photovoltaic systems: grid-tied (on-grid system), hybrid system and off-grid system.   The grid-tied solar PV system is one of the solar systems that is connected to the electrical power grid permanently. As in the case of off-grid solar systems, grid-tie does not need batteries. Grid-tie solar PV systems allow to use of solar energy when available or to transmit excess power back into the grid.   The hybrid solar PV system is also known as a grid-tied solar PV system with battery backup. The hybrid solar PV system is a most helpful solar system if you live in a district where the electrical grid is unreliable, an area that takes a long time to repair to the grid, or the extreme weather events are common. Moreover, it provides a hybrid of the benefits of grid-tie solar, for example, using clean and renewable solar power as the primary source of electricity and selling excess power to the utility through net metering.   An off-grid solar PV system refers to an installation that does not connect to the electricity grid. It means all the energy produced is stored and used on site. Generally, off-grid solar photovoltaic systems operate from the energy stored in a battery bank.   How does the solar PV street lighting system work?   You may notice a dark panel on top of the light when you see a solar street light on the road. That is the solar panel of the photovoltaic cells that will convert sunlight into electricity. And the electricity will be stored in the solar light batteries. Then the solar power can be used as and when needed. The solar lighting batteries will charge themselves continuously while the solar panel is being exposed to available sunlight. Inbuilt battery solar street light, as the batteries are inbuilt into the solar lighting systems, so the solar street lights are capable of drawing light from them. Solar street lighting systems are always wireless, there is no need to be attached to wires, for power transmission.   Types of PV solar panels   PV solar panels play the important role in solar products, they capture the sun’s energy and convert it into electricity so that the solar products can work. There are three main types of PV solar panels are monocrystalline, polycrystalline, and thin-film solar panels. Each of these PV solar panels is made in a unique way and has a different aesthetic appearance.   Monocrystalline solar panels When people mention monocrystalline solar panels, generally they are known as used for premium solar products. The main advantages of monocrystalline panels are higher efficiencies and sleeker aesthetics than the other solar panels. Monocrystalline solar panels are made from about 40 of the monocrystalline solar cells. These solar cells are made from pure silicon. Silicon is formed into bars and cut into wafers, in order to make solar panels with monocrystalline solar cells. These solar panels are called “monocrystalline” to indicate that the silicon used is single-crystal silicon. As a monocrystalline cell is made up of a single crystal, the electrons that generate a flow of electricity have more room to move. Therefore, monocrystalline solar panels are more efficient.   Polycrystalline solar panels As the same as monocrystalline solar panels, polycrystalline solar panels are also made from silicon. However polycrystalline cells are made from fragments of the silicon crystal melted together. Polycrystalline solar cells are called “multi-crystalline”, or many-crystal silicon. There is less freedom for the electrons to move because polycrystalline solar cells are many crystals in each cell. As a result, polycrystalline solar cells have lower efficiency ratings, but their advantage is a lower price point. Nowadays, polycrystalline solar panels are rising quickly in popularity and efficiency, even though they are a newer development.   Thin-Film Solar Panels Thin-film solar panels aren’t always made from silicon, they can be made from a variety of materials, such as cadmium telluride, amorphous silicon, and copper indium gallium selenide, this is the most distinguishing feature of thin-film panels. Thin-film solar panels are the newest development in the solar panel industry now.   Benefits of solar photovoltaic street lighting systems 1. Solar PV lighting system provides clean and green energy sources. There is no need to worry about the panels generating any harmful substance into the air. 2. There is no need to pay for raw materials, as solar PV system depends on solar energy to produce electricity. Solar power is natural, free, and available in abundance for a long time. People can save on electricity costs once start using the energy generated by PV cells. 3. Solar PV systems can generate electricity anywhere. All it needs is sunlight, making it a useful energy source in the outdoor environment. 4. Solar PV system has an important role in smart energy networks, which work on distributed power generation. It is very environmentally friendly because it helps reduce the production of electricity at centralized power plants. 5. Solar PV systems reduce costs, they are also a renewable energy system promoted through government subsidy funding. 6. Compared with other renewable energy systems, solar PV systems are known for low maintenance and operating costs. 7. Because solar PV systems are silent and won’t produce any noise, they are perfect for urban areas and residential applications. 8. Solar PV systems are easy to install.

Basics of Solar Light Panels
Basics of Solar Light Panels
  1. What are the components of a solar light panel? (Bonus question) Ultra-white high-transmission fabric tempered glass, EVA, conductive nickel-plated copper strip, battery cells, TPT backplane, aluminum alloy frame, junction box.   2. Please briefly introduce what are the characteristics of the solar light panel glass? Super white mainly reflects good light transmission, cloth pattern is tempered glass with many groove points, the sunlight refracted through the groove points on the cloth pattern glass to achieve the most reasonable use of sunlight, if the glass does not do cloth pattern processing power generation efficiency will be reduced by 30%, if you do not use super white non-blue glass, power generation efficiency will be reduced by 10%.   3. Why are the colors of polysilicon solar light panels different? Just like its name, polycrystalline cell chip, its manufacturing process is simpler and cheaper than single Du crystal. But at the same time, its efficiency is lower than that of monocrystalline silicon. It is thought that the polycrystalline cell is composed of many small crystal blocks with different crystal orientations, and the boundary between them is the grain boundary. The existence of these grain boundaries acts as the load center, absorbing some carriers, resulting in a slightly lower efficiency. From an optical point of view, the crystal regions with different orientations will have different optical reflection effects, and the intuitive feeling will be the appearance of patches. In addition, the front of ghost film is coated (SiNx). The thickness of the film also determines the color of this side (blue or darker). The uniformity of the coating will further affect the color uniformity.   4. What is sunshine coefficient? How many hours is the sunshine coefficient in Guangdong Province? What are the requirements of sunshine coefficient for the configuration of solar lamps? The sunshine coefficient refers to the time that the Solar Center irradiates the ground from the eastern horizon to the western horizon under any shielding conditions such as ground objects, clouds, etc., which is called the sunshine coefficient. The sunshine coefficient of Guangdong Province is about 3.5H Customers with sunshine coefficient higher than 4H are generally recommended to use monocrystalline silicon solar light panels, while customers with sunshine coefficient lower than 4H are recommended to use polycrystalline silicon solar light panels. The lower the sunshine coefficient is, the worse the power generation efficiency of solar light panels is. It is suggested to increase the configuration of solar light panels.   5. What is the installation angle of the solar light panel? 45 ° Southwest     6. Why does monocrystalline silicon have chamfering? The corner cutting of monocrystalline silicon solar light panels is mainly in the early development of solar light panels, in order to distinguish between single crystal and polycrystalline, there is no practical use.   7. What is the difference between monocrystalline silicon and polysilicon? How should we choose? (1) Monocrystalline solar light panels have high cell conversion efficiency and good stability, but the cost is higher.  (2) polycrystalline silicon solar light panels cost less, conversion efficiency is slightly lower than straight pull monocrystalline silicon solar light panels, various defects in the material, such as grain boundaries, dislocations, micro-defects, and impurities in the material carbon and oxygen, as well as the process of tarnishing the transition group metals are considered to be the cause of polycrystalline silicon solar panels photoelectric conversion rate has been unable to break through the 20% barrier. Polycrystalline silicon is a little better than monocrystalline silicon for low light power generation.  It is recommended to use monocrystalline silicon solar light panels where the sunlight factor is above 4h, and polycrystalline silicon solar panels where the sunlight factor is below 4h.   8. As the temperature increases, does the output voltage of the solar light panel decrease or increase? Lower, with 20 degrees Celsius as the base, for every 1 degree Celsius increase, the voltage of the unit cell (1.5V) as the base, the voltage of the cell decreases by 2mv   9. What factors may cause the low voltage of solar light panels? (1) Shade, leaves, bird droppings and other shading When there are shade, leaves, bird droppings or other shading objects to prevent sunlight to photovoltaic modules, it will lead to the shading part does not generate electricity, resulting in low voltage of the whole module, for example: a polycrystalline photovoltaic module 60 pieces, each cell voltage is 0.5V, then the whole module voltage is normally 30V. when the shade blocked the component 10 cells, the component voltage is only 25V. (2)Cell source itself problems There are multiple reasons affecting the open-circuit voltage of the cell: 1. High/low resistivity of the raw material of the wafer; 2. Diffusion, including diffusion square resistance, diffusion pollution; 3. Printing paste and sintering. Of course these problems need professionals and testing instruments to check. (3) Encapsulated backsheet failed Solar cell backsheet is also known as solar cell backsheet film, photovoltaic backsheet, photovoltaic backsheet film, solar backsheet. Widely used in solar cell (photovoltaic) modules, located on the back of the solar panel, in the outdoor environment to protect solar cell components from water vapor erosion, hinder oxygen to prevent internal oxidation of the components, with reliable insulation, water resistance, aging resistance, high and low temperature resistance, corrosion resistance. It can reflect sunlight and improve the conversion efficiency of the module; it has a high infrared reflectivity and can reduce the temperature of the module. According to the classification of different materials, backsheet can be divided into FPF (represented by TPT), KPK, FPE (represented by TPE), KPE and multi-layer PET backsheet, TAPE (aluminum layer added between T and P layers), TFB (PVF/PET/fluorine bonding layer), KFB (PVDF/PET/fluorine bonding layer), BBF (THV/PET/EVA), and FFC(PET double side coated with modified PTFE), KPC(PVDF/special treatment PET), KPF(invented by Suzhou Sellwood, fluorine skin film technology, structure is PVDF/PET/fluorine skin film), PPC(special treatment PET/weather resistant PET), etc. Similarly, the backsheet is divided into three layers, if the encapsulation material is not qualified, that is, the backsheet and EVA matching does not reach the adhesive force of the work instructions, in the process of use will make the components separate between each layer or the backsheet and EVA separate, resulting in wet or rainy weather PV modules into the internal water, the component voltage becomes low resulting in low resistance of the PV system to ground, thus affecting the system power generation. (4) Cell hidden crack Hidden crack is a defect of the cell. Due to the own characteristics of the crystal structure, crystalline silicon cells are very prone to rupture. The process of crystalline silicon module production is long, and many links may cause hidden cracking of cells (according to the information of Mr. Yang Hong of Xi'an Jiaotong University, there are about 200 causes in the cell production stage alone). The generation of hidden cracks will affect the whole module, and the cracked part of the cell will not generate electricity, or even turn into a resistor to affect other cells to generate electricity. There are three reasons for hidden cracks to arise: during the production process, during the storage period, and during the installation process.     10. What are the possible causes of low solar light panel power generation efficiency? (1) Improper installation position, poor welding process, packaging process there is a lack of glue phenomenon, or due to solar panels in handling, installation process improper operation, or even solar panels in the use of the process of hail violent impact and lead to solar panels breakage affect power generation efficiency (2) If it is used for a period of time, the short-term may be the surface is not clean enough, the light becomes worse, the ambient temperature, long-term is the cell attenuation is more serious (3) Silicon wafers with inefficient pieces, or mixed with invalid pieces, etc.
Quantum Process Helps Solar Panels Double Energy Output
Quantum Process Helps Solar Panels Double Energy Output
In 10 seconds? Researchers have come up with two different ways to boost the efficiency of solar cells by tinkering with light on the subatomic level and helping save money in the process. (Read the science)Care to shed some light on this? Well, solar panels are not so expensive to make, but solar farms are hosted on expensive land. So any boost in efficiency means they can take up less space. To solve this problem, scientists have found a way to harness parts of the light spectrum that were previously useless for solar cells. (Find out more)And what’s the subatomic magic here? Solar cells generate electrical current when light particles (photons) hit their semiconductor surface. In this process, pairs of ‘charge carriers’ are created and travel to the negative and positive contacts. But not all photons can do this: the ones in ultraviolet waves aren’t harnessed efficiently, and the ones in the infrared range are ‘wasted’ as they just pass through the solar cell. So scientists added some crystals to the panels’ surface to harness infrared light too, in a process called upconversion. (Read the paper)Wait, this sounds like some fantasy novel! Nope, it’s science and here is how it’s done: researchers combined semiconductor nanocrystals and a different class of molecules into the surface of the panels. This combination can ‘upconvert’ photons to the visible and near UV-range of the sunlight spectrum — which is precisely the kind of light that silicon-based solar panels can convert into electricity. (Read More)Cool, and what sort of process is at play here? The materials of the panel work as a team — the organic component captures and turns high energy photons into two low-energy charges which are passed to the to the non-organic part. This can be turned by the cells in the solar panel into energy. This process is called singlet fission. (More on singlet fission)So when will this become a reality? Well, so far these phenomena have only been achieved in a few state-of-the-art materials, which are expensive — and decompose if exposed to light and air! So, my research focuses on the design and synthesis of new molecules that can undergo singlet fission and upconversion, without the drawbacks. We’ve been working on this for the past couple years, and we’ve got some cool new molecules that should be published soon, so stay tuned!Using upconversion for targeted drug releaseThe process of upconversion can also be combined with photoredox catalysis, that allows for new and more complex molecules to be made more easily than ever before.This is an attractive proposition for photodynamic therapy. For example, an inactive pro-drug could be injected into the body, and then selectively activated in only one part of the body with infrared light.In the treatment of cancer, rather than poisoning the entire body with a toxic drug, the active drug could also be selectively generated only at the tumor site, by irradiating with a simple infrared light.Research curated by Andrew PunAndrew is PhD student at Columbia University, researching, exciton fission, upconversion, photovoltaics and photoredox.(Psst, Andrew distilled 10 research papers to save you 798.4 min)Originally published at www.sparrho.com·RELATED QUESTIONI didn't get Google Glass Explorer Edition. Is trying to learn Glass dev without the hardware a futile effort?No, you can still learn the fundamentals of Glass development without the hardware.There are three main approaches for accomplishing this:1) Visit the Mirror API documentation, get into the playground, and start hashing up some code. Download the PHP, Java, and Python library, whichever you're most comfortable with. Familiarize yourself with the jargon and converntions (timeline, bundles, menus, etc). Read the support documentation (second link below) to see how the Glass hardware actually functions. Build some apps to this specification. Soon enough, you will find a friend with hardware to t

The corner cutting of monocrystalline silicon solar light panels is mainly in the early development of solar light panels, in order to distinguish between single crystal and polycrystalline, there is no practical use.   7. What is the difference between monocrystalline silicon and polysilicon? How should we choose? (1) Monocrystalline solar light panels have high cell conversion efficiency and good stability, but the cost is higher.  (2) polycrystalline silicon solar light panels cost less, conversion efficiency is slightly lower than straight pull monocrystalline silicon solar light panels, various defects in the material, such as grain boundaries, dislocations, micro-defects, and impurities in the material carbon and oxygen, as well as the process of tarnishing the transition group metals are considered to be the cause of polycrystalline silicon solar panels photoelectric conversion rate has been unable to break through the 20% barrier. Polycrystalline silicon is a little better than monocrystalline silicon for low light power generation.  It is recommended to use monocrystalline silicon solar light panels where the sunlight factor is above 4h, and polycrystalline silicon solar panels where the sunlight factor is below 4h.   8. As the temperature increases, does the output voltage of the solar light panel decrease or increase? Lower, with 20 degrees Celsius as the base, for every 1 degree Celsius increase, the voltage of the unit cell (1.5V) as the base, the voltage of the cell decreases by 2mv   9. What factors may cause the low voltage of solar light panels? (1) Shade, leaves, bird droppings and other shading When there are shade, leaves, bird droppings or other shading objects to prevent sunlight to photovoltaic modules, it will lead to the shading part does not generate electricity, resulting in low voltage of the whole module, for example: a polycrystalline photovoltaic module 60 pieces, each cell voltage is 0.5V, then the whole module voltage is normally 30V. when the shade blocked the component 10 cells, the component voltage is only 25V. (2)Cell source itself problems There are multiple reasons affecting the open-circuit voltage of the cell: 1. High/low resistivity of the raw material of the wafer; 2. Diffusion, including diffusion square resistance, diffusion pollution; 3. Printing paste and sintering. Of course these problems need professionals and testing instruments to check. (3) Encapsulated backsheet failed Solar cell backsheet is also known as solar cell backsheet film, photovoltaic backsheet, photovoltaic backsheet film, solar backsheet. Widely used in solar cell (photovoltaic) modules, located on the back of the solar panel, in the outdoor environment to protect solar cell components from water vapor erosion, hinder oxygen to prevent internal oxidation of the components, with reliable insulation, water resistance, aging resistance, high and low temperature resistance, corrosion resistance. It can reflect sunlight and improve the conversion efficiency of the module; it has a high infrared reflectivity and can reduce the temperature of the module. According to the classification of different materials, backsheet can be divided into FPF (represented by TPT), KPK, FPE (represented by TPE), KPE and multi-layer PET backsheet, TAPE (aluminum layer added between T and P layers), TFB (PVF/PET/fluorine bonding layer), KFB (PVDF/PET/fluorine bonding layer), BBF (THV/PET/EVA), and FFC(PET double side coated with modified PTFE), KPC(PVDF/special treatment PET), KPF(invented by Suzhou Sellwood, fluorine skin film technology, structure is PVDF/PET/fluorine skin film), PPC(special treatment PET/weather resistant PET), etc. Similarly, the backsheet is divided into three layers, if the encapsulation material is not qualified, that is, the backsheet and EVA matching does not reach the adhesive force of the work instructions, in the process of use will make the components separate between each layer or the backsheet and EVA separate, resulting in wet or rainy weather PV modules into the internal water, the component voltage becomes low resulting in low resistance of the PV system to ground, thus affecting the system power generation. (4) Cell hidden crack Hidden crack is a defect of the cell. Due to the own characteristics of the crystal structure, crystalline silicon cells are very prone to rupture. The process of crystalline silicon module production is long, and many links may cause hidden cracking of cells (according to the information of Mr. Yang Hong of Xi'an Jiaotong University, there are about 200 causes in the cell production stage alone). The generation of hidden cracks will affect the whole module, and the cracked part of the cell will not generate electricity, or even turn into a resistor to affect other cells to generate electricity. There are three reasons for hidden cracks to arise: during the production process, during the storage period, and during the installation process.     10. What are the possible causes of low solar light panel power generation efficiency? (1) Improper installation position, poor welding process, packaging process there is a lack of glue phenomenon, or due to solar panels in handling, installation process improper operation, or even solar panels in the use of the process of hail violent impact and lead to solar panels breakage affect power generation efficiency (2) If it is used for a period of time, the short-term may be the surface is not clean enough, the light becomes worse, the ambient temperature, long-term is the cell attenuation is more serious (3) Silicon wafers with inefficient pieces, or mixed with invalid pieces, etc.
