Photovoltaic power generation has spread to every household and every household. With the series of subsidy policies issued by passengers, photovoltaic power generation has been included in pension investment projects, but many people still do not understand the installation and income issues. Here are these. A one-off solution to the problem, so that everyone has an understanding of costs and benefits.
According to the "National Development and Reform Commission's Notice on Exploiting Price Leverage to Promote the Healthy Development of the Photovoltaic Industry", the country is divided into three types of solar energy resource regions in accordance with the conditions of solar energy resources and construction costs in various regions, and the benchmark on-grid tariffs for photovoltaic power stations are accordingly established. The part of the photovoltaic power plant benchmark on-grid price that is higher than the local coal-fired unit benchmark on-grid tariff (including the desulfurization and other environmental protection tariffs) is subsidized through the renewable energy development fund.
First, installation income
installation fee
The residential photovoltaic system needs about 30,000-100,000 yuan, depending on the roof area of ​​the home, as well as the budget that can be invested. Here to remind Oh, photovoltaic components, inverters, brackets and wires must choose quality and guaranteed products, so as to ensure 25 stable income.
Take the Shijiazhuang, Hebei Province, 5.1KW photovoltaic power plant as an example, the installation price is about 50,000. Can be installed on cement roofs, tile roofs and color steel roofs.
Revenue calculation: There are two grid connection modes for household solar power plants, which are as follows:
Spontaneous use of self-use Internet: that is, photovoltaic electricity generated by its own part, can not be sold to the grid, and every time you send a power can get PV subsidies.
The full amount of access to the Internet: that is, all the electricity generated by photovoltaics is sold to the power grid, and they are not used at one time. In this case, the grid purchases all the electricity generated by the power station at the on-grid price of the local photovoltaic power generation benchmark.
How to calculate the revenue of two grid-connected models?
Taking Shijiazhuang in Hebei Province as an example, under the mode of self-use over-grid access, the income from electricity subsidies is 0.62 yuan per kWh (including state subsidies of 0.42 yuan and provincial subsidies of 0.2 yuan); the full-subsidy electricity subsidy yields 1.18 yuan. / Degree (of which Hebei photovoltaic power generation benchmark on-grid price is 0.98 yuan, 0.2 yuan for provincial subsidies).
The residential electricity price is 0.52 yuan/kWh and the selling price is 0.35 yuan/kWh.
With the sunshine conditions in Hebei, it is expected that a 5kW power station can produce 8100 kWh of electricity a year. The annual electricity consumption of residents is initially set at 2000 degrees.
Self-use Internet access:
One thousand degrees uses electricity generated by photovoltaics, and the other 1000 degrees buys electricity from the grid.
1. Revenue from selling electricity: (8100-1000)×0.35=2495.65 (yuan)
2. Subsidy income: 8100×0.62=5022 (yuan)
3, the use of electricity to pay: 1000 × 0.52 = 520 (yuan)
Total income: 2495.65+5022-520=6997.65 (yuan)
Full Internet access:
1. Subsidy income: 81000×1.18=9558 (yuan)
2, electricity charges: 2000 × 0.52 = 1040 (yuan)
Total income: 9558-1040=8518 (yuan)
To sum up, it can be concluded that the cost for installing a set of 5.1KW domestic photovoltaic power station is 50,000 yuan. If you use the self-consumed residual power online mode, you can get back to this in 7.2 years; if you use the full amount of online mode, 5.9 years, you can return to this .
Therefore, if the electricity consumption is not too large and there is no more than one stall price, the current mode of operation will be more appropriate for the full amount of access.
Second, photovoltaic loan
Loan conditions: According to the “Opinions on Supporting Distributed Photovoltaic Power Generation Financial Services†formulated by the National Development Bank of the United Nations, the enterprises and corporations with good credit status and no significant bad records and natural persons with complete civil liabilities can apply for bank loans. .
Loan Limit, Term, and Repayment Mode: With reference to China's regulations on the capital system of investment projects, users should raise at least 20% of the total capital of the project, and the corresponding proportion of bank loans applied for can reach 80%. With reference to medium and long-term loans for power projects, according to the actual conditions of lenders and projects, the term of a distributed photovoltaic power generation project can generally be up to 15 years.
The repayment method can generally be implemented with equal principal and interest or equal principal repayment method.
Information required for the loan: Materials that borrowers applying for a bank loan generally need to prepare: natural person identification, individual asset certificate or business license, company charter, financial audit report for the past three years, project filing, power access approval, site or roof Tenancy agreements, power purchase agreements, energy management contracts and other related documents. In general, prior to the issuance of the loan, the completion of project registration and the signing of relevant agreements such as power purchase agreements and energy management contracts shall be completed.
Third, the installation conditions
1, have a clear roof or roof property rights
2, the roof is in good condition
Through the above introduction, I believe that everyone should have a preliminary understanding of the installation costs and benefits of photovoltaic power generation. For some regions, the provincial subsidies may not be the same. The above information is only for reference. PV module materials also have subsidy fees. Specific questions can be asked.
