The hardware required for the installation of a household solar power system includes distribution boxes, photovoltaic module brackets, etc. The price of the hardware is not particularly cheap, and the cost of installing a solar power system in a household is relatively large except for some hardware equipment. The relationship also has a greater relationship with the installed capacity of the solar power system. Generally speaking, the installation area of the roof of a bungalow is 10 square meters for every 1000 watts. Calculated according to the current price standards established by the solar power generation system industry, if the installation and after-sales service of the system are included, an investment of about RMB 35,000 is required for 5 kilowatts, and an investment of about RMB 70,000 for 10 kilowatts.
