What are the preferential policies for photovoltaic power generation on family roofs? Is there solar energy for family villas in Hangzhou?

First, the state subsidy is 0.42 yuan/kWh, hereinafter referred to as the state subsidy, which is the state subsidy price per kWh of photovoltaic power plants;

Second: Photovoltaic power station generates electricity to see what your purpose is, whether you want to use it spontaneously or use excess electricity to access the Internet in full. Under normal circumstances, we usually use this spontaneous self-use and surplus power mode to surf the Internet. As for the remaining electricity on the Internet, that is, the electricity sold to the country, the electricity price in each region is different. Here, taking Hefei as an example, give a concrete example to illustrate the benefits of photovoltaic power generation:

The data of electricity consumption and power generation may not match the actual situation, just for the convenience of calculation, but the reason is the same. )

Take the electricity consumption and power generation in one day as an example; suppose

The output of photovoltaic power station is 100 kwh, so the national compensation is100 x 0.42;

Electricity needs 30 degrees during the day (for personal use). This 30-degree electricity is generated by the photovoltaic power station installed by ourselves, and there is no need to buy electricity from the national grid. China's civil electricity price, taking Hefei as an example, is 0.56 yuan/kWh. In this sense, we say that the photovoltaic power station has saved you 30x0.56 yuan, which is a harvest;

Electricity consumption at night is 20 degrees (photovoltaic power station does not generate electricity at night and needs to be purchased from the state), 20x0.56 yuan;

100 kwh is generated, 30 kwh is used for personal use, that is, the remaining 70 kwh can be sold online. Taking Hefei as an example, the electricity price of surplus electricity is 0.4 16 yuan/kwh, that is to say, the income of this electricity is 70x0.4 16 yuan.

So the total income of one day can be expressed as:100x0.42+(100-30) x0.416+30x0.56-20x0.56.

Third: Different regions will also lead to different subsidies and different incomes.

I hope I can help you! (Anhui Yisen New Energy)

Hello:

At present, there are mainly two kinds of photovoltaic power generation: spontaneous self-use surplus electricity and full internet access.

The national financial subsidy for spontaneous self-use is 0.42 yuan/kWh, and the remaining electricity is recovered according to the local desulfurization electricity price (step-by-step charging).

All power generation connected to the whole power grid shall be purchased by power grid enterprises according to the benchmark on-grid electricity price of local photovoltaic power stations.

Despise those black-hearted advertisements that mislead consumption!

Solar power generation, the power generation per square meter is about 120w, and the cost per square meter is about 1500 yuan. The larger the area, the lower the price.

20 13 photovoltaic industry is under antitrust investigation in Europe and America. Overcapacity led to the closure of a large number of photovoltaic industries in Zhejiang, and the price of solar energy fell. This can be checked online at any time.

It is recommended to buy a solar water heater at the price of 150- 180 yuan, including other expenses such as materials. And we are optimistic about whether there is reliable after-sales service in the local area.

If solar panels are used to generate electricity, it is suggested that the group should invite public bidding on a large scale, mainly because the power transformation and storage equipment are expensive, with the highest conversion rate of 17%-20%, and the efficiency is very low, which is not as good as plant photosynthesis.

At present, the national support policy for clean energy and photovoltaic power generation is that 10kw or above can be connected to the grid for free, but the electricity price recovery is very low and the procedures are cumbersome.

The monthly sales of rooftop photovoltaic power generation is less than 20 thousand yuan, tax-free. According to the national fiscal and taxation policy, the power generator needs to provide sales invoices to the power supply enterprises, and the buyer also needs invoices to offset the costs. However, individual power generation does not have the qualification of industrial and commercial owner, and the procedures for receiving invoices are complicated. More than 20,000 yuan will be taxed by half.

"If you can't get the invoice, it will increase the sales difficulty of power producers, which is not conducive to promotion. The release of State Taxation Administration of The People's Republic of China will reduce the tax burden of power generation households. "

According to State Taxation Administration of The People's Republic of China's document, from July 1 day, 2004, State Grid Corporation issued an invoice for purchasing power products for distributed photovoltaic power generation projects. If the monthly sales of generator power products exceed 20,000, the enterprises affiliated to the State Grid will levy VAT at 50% of the tax payable. The monthly sales below 20,000 yuan can be exempted from VAT.

According to the policy issued by State Taxation Administration of The People's Republic of China last year, from the date of 20 13, 10, 1 to the date of 20 15, 12, 3l, the levy rate is calculated at 3%. Take Takamatsu as an example. If the monthly sales is 30,000, the tax he should pay is 30,000× 3 %× 50% = 450 yuan.

Every time residents generate 1 kwh, the state subsidizes 0.42 yuan; The state buys self-generated electricity that residents can't use up at the price of desulfurized coal, and the price is also 0.42 yuan per kWh. Based on the average installed cost 1 kw of installing and using distributed photovoltaic power generation system, it is about 1 10,000 yuan. If the average daily power generation of 8 kW system is 30 kwh, and the household electricity consumption is 5 kwh per day (not exceeding the first-class electricity price of 0.52 yuan), the investment can be recovered in about 8 years.

According to the same calculation method, it will take 9- 10 years to recover the cost of10 distributed photovoltaic power generation device.

The average cost recovery period of household photovoltaic power plants is between 8- 10 years.
