① According to provides electric power the type to be possible to divide into the direct current power supply system, the exchange power supply system and the alternating and direct power supply system three kinds;
② Obtain the way according to the system composition or the energy to divide, may divide into the light photovoltaic power supply system, the wind power generation system, the scenery supplementary power supply system;
③ Is different according to the system movement pattern, may divide into to the net system (independent movement electricity generation) and the incorporation generating system.
Performance characteristic：
① Does not need to pull supposes the electric wire, does not need to dig up the street, installs the easy to operate；
② The independent system disposable investment, may guarantee 20 years uninterrupted power supply (accumulator cell is generally 5 years must replace)；
③ Exempts the maintenance, does not have any pollution；
④ The incorporation system may omit the accumulator cell, turns on the electrical network directly。
Merit analysis：
① Does not have dries up the danger；
② Clean (does not have environmental damage) absolutely；
③ Is not distributed the resources the region the limit；
④ But using electricity place nearby is generating electricity；
⑤ The energy quality is high；
⑥ The user is easy from the sentiment to accept；
⑦ The gain energy expenditure time is short。
Shortcoming elaboration：
① The illumination energy distribution density is small, namely must take the huge area；
② Obtains the energy same four seasons, the day and night and cloudy are clear and so on the meteorological condition related。
But the generally speaking, the best words to say,to take the new energy, the solar energy has the enormous merit, therefore receives the various countries the ＆#118alue. |
