Home build 5KW distributed photovoltaic power plant costs

Take the example of a family-built 5 kilowatt photovoltaic power station. The installation needs to consider whether there is a sufficient area on the roof. The power station requires about 10 square meters of panel per kilowatt, and 5 kilowatts will require 50 square meters. With the current market price of domestic photovoltaic power stations, the total cost will add up to an average of 1 watt and 10 yuan.

1. Battery board: The material for the market is 4 yuan/watt, 5 kilowatts and 2 million yuan.

2. Installation material fee (city): aluminum alloy material bracket ≈ 5000 yuan, ordinary steel bracket ≈ 3,000 yuan (if the roof in rural areas is mostly spire, do not need bracket, will save some money)

3. Supporting equipment:

Convergence box ≈400-500 yuan (collects the current of all the panels, plus the lightning protection function, most of which are not set up separately, but put this function on other instruments)

Inverter (good quality) ≈ 10,000 yuan (The DC power generated by the panel becomes an AC suitable for home appliances, as well as functions such as short-circuit prevention and communication)

4. Labor costs ≈8000 yuan

Local grid companies provide free services.

The total cost is nearly 50,000 yuan.
