To give you some data, the complete system (including solar panels, inverters, batteries and charging devices) costs around 18 yuan/watt. So if you need to install a 3,000 kilowatt solar power system, this will be it. costs around 50,000 to 60,000 yuan. Solar power systems with too low power are generally not suitable. Usually a family has a refrigerator, a TV, a 1.5 HP air conditioner, 2-3 lamps, etc., which require around 2000 watts. Generally, a home solar power generation system should be around 3 kW. Just calculate it in watts.
Compared with commonly used thermal power generation systems, the advantages of solar photovoltaic power generation are mainly reflected in:
① No risk of depletion ② Safe and reliable, no noise, no noise; THEpollution emissions, absolutely clean (no pollution); ③ not limited by the resource distribution area, can take advantage of the roof of the building; ④ can generate electricity on site without consuming fuel or erecting transmission lines ⑤ high power quality; accept emotionally;⑦ The construction period is short and the time spent on obtaining energy is short.
Disadvantages:
① The energy distribution density of irradiation is low, that is, it occupies a huge area ② The energy obtained is related to the four seasons, day and night, cloudy and sunny and other weather conditions. The origin and development of photovoltaic solar energy production.
