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
At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
Q:What is the working principle of solar panels?
Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
Q:Can cold light make solar panels power
light - heat - dynamic - electric conversion method through the use of solar radiation generated by thermal power, usually by the solar collector will absorb the heat energy into the refrigerant, and then drive the turbine power generation. The latter process is the light-heat transfer process; the latter process is the heat-to-conversion process, which is the same as the conventional thermal power generation.
Q:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
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?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array
Q:How many solar panels have ah?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
