Problems solved by technology

[0003] Although the total amount of solar radiation reaching the earth's surface is large, the energy flow density is very low. The utilization of solar energy is actually the collection and utilization of low-density energy.

Currently popular solar photovoltaic power generation systems on the market are mostly crystalline silicon cells and amorphous silicon photovoltaic cells. The conversion efficiency of crystalline silicon photovoltaic cells is 13% to 20%, while that of amorphous silicon photovoltaic cells is only 5% to 10%. Too low, so that the power density of photovoltaic power generation is low, and it is difficult to form a high-power power generation system

The impact of environmental factors is great. Particles (such as dust) in the air settle on the surface of the solar cell module, blocking part of the light, which will reduce the conversion efficiency of the cell module, resulting in a reduction in power generation and partial shading to generate heat. spots, causing damage to the battery board

The manufacturing process of crystalline silicon cells is highly polluting and energy-intensive, and will also cause certain environmental pollution

The most basic unit of photovoltaic power generation is a solar cell module. To obtain a certain conversion power, a set of collection and conversion equipment with a relatively large area is often required, and the cost is relatively high.
