The national subsidy policy for distributed photovoltaic power generation refers to the subsidy standard of 0.42 yuan per kilowatt hour, and the implementation period is generally 20 years. According to national policies and actual local conditions, each province and city formulates different subsidy standards, including national subsidies, provincial subsidies, municipal subsidies and county-level subsidies, which ultimately constitute the price of the photovoltaic electricity on the network.
Approximately 22 kW of battery panels are needed to produce 70 kilowatt hours of electricity per day. We just made an engineering panel and bought it for 4.9 yuan/watt.You need a battery to use it for 2 days. Panels and inverters are more expensive. Let me estimate that the battery panel is 11W and the inverter is 20kW, so about 6W. The batteries shouldn't be expensive. The special photovoltaic cable costs 0.4 yuan/watt, which costs about 8,800 yuan. The stand is rated at 4W and requires a few other accessories, making it around 25W total. The price I wrote does not take into account construction costs, and it is also a relatively low price. The area should be approximately 680 square meters.
