1 If private power supply enterprises are understood as "individuals" as you said, there should be some individuals investing in wind energy storage and power generation projects in China at present, and there should be no purely personal solar power generation projects (the return on investment is not good).
Solar panels are just photoelectric conversion devices. Solar panel power generation is static, and there is no "intermittent" problem as you think (is sleeping harmful to your health because you don't work continuously). The interconnected power grid is like a big power mechanism, which can completely make up for the "intermittent" of solar power generation (just like many people swimming in the river but the water surface remains the same).
Generally, small solar panels usually do not use the light-chasing service mechanism, because it is not as cost-effective as increasing the area of photovoltaic panels. Some large-scale solar power stations will adopt light-chasing service organizations.
The power of solar panels is mainly proportional to the area of photovoltaic panels, and secondly related to the process of photovoltaic cells.
