The total installation price of 3 kW to 5 kW solar photovoltaic power generation system in 2020 is about 15,000 to 22,000 yuan, and the market price of the terminal is about 3.5-4.5 yuan/W 1. This price includes the total of all installation costs. The products and the network connection now seem relatively cheap.
And if photovoltaic power generation is installed in 2020, there will be a power generation subsidy of 0.08 yuan/kWh. If you want to install it, you need to hurry up and make arrangements now~
To give you some data, the complete system (including solar panels, inverter, battery and backup device charging) costs around 18 yuan/watt. So if necessary, it costs around 50,000 to 60,000 to install a 3,000 kilowatt solar power generation system. Solar energy production systems with too much powerible 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; pollution 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 obtainingenergy 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.
