Distributed Home Solar Power Generation System
Solar power generation systems are generally installed on rooftops, balconies, or yards. Large distributed photovoltaic power stations are suitable for installation on idle land. What size solar photovoltaic power generation system is suitable for home installation?

Taking distributed home solar power stations as an example, let’s look at the area and cost of solar power generation:
Cost of Installing Distributed Photovoltaic Power Stations
Home Solar Photovoltaic Power Station Installation Cost
This is a topic of concern for many. Solar photovoltaic power generation systems are currently a key industry encouraged by the country. For home solar power stations, not only has the government provided strong policy support, but it has also increased support for photovoltaic enterprises. One can imagine that this is a promising investment project, especially during the current good development period of photovoltaic power generation.
For a 5 kW home solar photovoltaic power generation system, the installation area is approximately 50 square meters. Given the current market construction prices for home photovoltaic power stations, the average cost is about 10 yuan per watt. It can generate 20-30 kilowatt-hours of electricity daily. After connecting the household solar power station to the grid, in addition to enjoying government subsidies, it can also provide income from selling electricity and local subsidies.
1. Solar panels: The current market price for good quality materials is about 4 yuan per watt. For 5 kW, this costs approximately 20,000 yuan.
2. Installation materials (in cities): Aluminum alloy brackets cost about 5,000 yuan, and ordinary steel brackets cost about 3,000 yuan (in rural areas, roofs are often pitched, and no brackets are needed, which saves some costs).
3. Inverter (high quality): Approximately 10,000 yuan (converts the direct current generated by the photovoltaic solar panels into alternating current suitable for household appliances and also offers short circuit protection, communication functions, etc.).
4. Supporting instruments: Junction box approximately 400-500 yuan (collects current from all photovoltaic solar panels and provides lightning protection; currently, most do not set this up separately but rather integrate this function into other devices).
5. Labor costs: Approximately 8,000 yuan. Some solar photovoltaic system manufacturers are producers and do not personally carry out installation work, necessitating hiring local installation personnel, hence the labor costs.
The above costs for a 5 kW solar photovoltaic power generation system are for reference only. Actual installation requires specific calculations based on particular circumstances. Additionally, please disregard any offers in the market claiming installations for just a few thousand yuan.
