How to choose a household solar photovoltaic power generation system

      Household solar photovoltaic systems are divided into three categories: independent photovoltaic power generation systems, grid-connected photovoltaic power generation systems and distributed photovoltaic power generation systems.

     Household solar photovoltaic power generation systems now generally choose grid-connected photovoltaic power generation systems. Because the state now has policies to subsidize photovoltaic power generation, the excess electricity can be sold to the country. The related grid-connected photovoltaic power generation system income is regionally:

Spontaneous self-use: 0.56/kWh (residential electricity price) + 0.42/kWh (national subsidy) + 0.25/kWh (provincial subsidy) = 1.23 yuan/kWh.

Surplus electricity to the Internet: 0.46 yuan/kWh (desulfurized coal-fired electricity price) + 0.42 yuan/kWh (national subsidy) + 0.25 yuan/kWh (provincial subsidy) = 1.13 yuan/kWh.

The current market price of photovoltaic power generation is about 10-12 pieces of 1KW. Of course, if you are looking for an agent, there will be a price difference, so it is recommended to find a direct household solar photovoltaic system manufacturer.

Need to pay attention to:

1. Solar photovoltaic power generator manufacturers have many partners or distributors. Because there are more people working together, they are naturally regular. If it is a fake black-hearted company, naturally there will not be so many people to cooperate with them.

2. Solar photovoltaic generator manufacturers must have certain qualifications and strengths, which will save a lot of time and cost, and service those aspects will be better. They can give reasonable suggestions and plans according to your situation, and cooperate more. People can rest assured that large companies are more secure.

3. The price of solar photovoltaic generators must be reasonable, and reasonable prices allow us to obtain more benefits in cooperation. In recent years, the price of solar generators has not been very stable. The current price of polycrystalline silicon panels should be 300W on a large scale. The price of a solar photovoltaic panel is about 1,200 yuan, and monocrystalline silicon is a little higher.
