No risk of depletion;
② safe and reliable, no noise, no pollution emissions, the absolute environmental (pollution-free);
③ not limited by the geographical distribution of resources, installed in the roof of the building at the same time the advantages of beauty;
④ no need to consume fuel and erection of transmission lines can be local power supply;
⑤ high energy quality (the highest laboratory conversion rate has reached more than 47%);
⑥ users from the emotional easy to accept and very fond of;
⑦ short construction period, access to energy to spend a short time;
⑧ from the national security point of view, photovoltaic power generation can achieve their own supply, to avoid the devastation caused by the war.
① The use of solar energy equipment must have a considerable area.
② the application of solar energy by the climate, day and night.
③ technical constraints, resulting in energy efficiency is not high, low efficiency, and equipment investment is higher.
④ solar panels: polysilicon production will bring great pollution. The use of solar power storage battery will also bring great pollution.
