(1) Reliable: photovoltaic power supply rarely uses moving parts and works reliably.
(2) Safe, no noise, no other pollution. It does not produce any solid, liquid and gaseous harmful substances, absolutely environmentally friendly.
(3) Simple installation and maintenance, low operating cost, suitable for unattended and other advantages. In particular, it is of great interest for its high reliability.
(4) Good compatibility, photovoltaic power generation can be used with other energy sources, and the photovoltaic system can also be easily increased according to needs.
(5) High degree of standardization, can be connected in series and parallel by components to meet the needs of different electricity consumption, strong versatility.
(6) Solar energy is available everywhere and has a wide range of applications.
However, solar energy systems also have their disadvantages, such as: energy dispersion, intermittency and strong regionality. Higher upfront costs.
