First of all, it is called clean energy because it uses solar energy and produces almost no pollution during the electricity generation process. Additionally, solar energy can be recognized as a sustainable energy source, which is why solar energy production is generally considered as such. a clean energy source.
They say it’s trash energy. First of all, it is because the cost of photovoltaic energy production is too high. At least now the price of solar photovoltaic modules has fallen a lot compared to. thermal energy production, the cost of solar energy production is still much higher. At the same time, for photovoltaic power generation to reach the quality of municipal power grids, harmonics and other components must be dealt with, which is expensive. A large part of photovoltaic energy production does not meet equality requirements of electricity users. , so it really sucks.
