Q:Why can not the solar panel load directly?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q:Can cold light make solar panels power
permanent, clean and flexible three major advantages of solar cells long life, as long as the sun exists, solar cells can be an investment and long-term use; compared with thermal power, Solar cells do not cause environmental pollution
Q:What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:Composition and function of solar panels
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Polycrystalline solar panels are good or single crystal solar energy is good
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:How many solar panels have ah?
The area of ​​the solar cell chip is not exactly the same as the area of ​​the solar package panel, because some solar panels, although large, single solar wafer arrangement gap is wide, so that the solar panel power is not necessarily high. 2, in general, the power of solar panels is the bigger the better, so that the current generated in the sun, and soon it will be filled with built-in battery.
