: In recent years, the state has issued a series of policies to support the development of photovoltaic industry, but because of the early investment, long recovery period, photovoltaic investment is the most concerned about the photovoltaic subsidy policy and can produce economic benefits.
Now the state of the PV industry subsidy for the August 2013 policy, "on the role of price leverage to promote the healthy development of the photovoltaic industry Notice", which stipulates a distributed generation subsidy policy, 0.42 yuan/kilowatt hour price subsidy, the implementation period in principle for 20 years. The state will gradually reduce electricity prices and subsidy standards according to the changes in the size and cost of photovoltaic power generation.
新疆11选5The National Development and Reform Commission last year adjusted the subsidy to 0.37 yuan/degree. Provinces and cities and according to the policy of different subsidy standards, the basic is: state subsidies + subsidies + municipal subsidies + County subsidies (after the three if any) = Final PV power price.
Streamlining of procedures
新疆11选5Waiver of supporting documents: exemption from power generation business licenses, planning sites, land pre-trial, soil and water conservation, environmental impact assessment, energy efficiency assessment and social risk assessment, and other supporting documents.
One-stop service: To encourage the municipal or county-level government to combine the local reality, set up with the grid access applications, grid debugging and acceptance, electricity billing and subsidies, such as the combination of the distribution of photovoltaic power generation project record, completion and acceptance of a one-stop service system to simplify the processing process.
Grid-connected free more simple: by the municipal or county-level grid enterprises in accordance with the simplification procedures for the relevant grid procedures, and free access to grid-connected consulting, electric energy meter installation, grid-connected commissioning and acceptance services.
Investment and recovery
First of all, initial investment, the price of household electricity generation is basically 8 yuan/watts, including components, inverter, stent equipment.
100 square meters of the roof, according to the use of component capacity, installation angle, installation capacity is very different, estimated to be able to install 3-10 kw of scale, cost investment is about 390,000 yuan.
Second, power generation equivalent hours, look at the local lighting resources. The following examples show that the local electricity price, installation capacity, etc. can calculate the income:
新疆11选5If there is an equivalent hour of about 1000 hours in a year, installation capacity is 10-kilowatt, then the annual generating capacity is 10-kilowatt * 1000 hours = 10,000-kilowatt.
If the local subsidy electricity price All on-line calculates has 1 yuan/watts, then the annual income is 10,000-kilowatt when * 1 yuan/watts = 10,000 yuan. Do not consider the battery attenuation 10 years can recover the input of 100,000 yuan cost, then is net income.
Here also need to consider is the component battery attenuation, another need to take into account that the state subsidy may last 20 years, or 10, the provincial and municipal subsidies vary by region, some subsidies five years, some subsidies for 3 years, the change is still very large.
Whether the contribution of environmental protection to society is valuable
PV is not only an economic account, but also an environmental account, you can roughly calculate the "environmental benefits" as follows:
Power consumption per kwh coal: At present, the coal consumption in China for the average 390 grams of coal/kwh;
新疆11选5Emission of carbon dioxide at 1-kilowatt per 1.4 kg;
Per watt PV modules are issued on average 2-kilowatt times a year;
Each watt PV module has an average annual emission reduction of 2.8 kg of carbon dioxide.
According to Epia estimates, PV power generation to replace diesel generators of carbon dioxide reduction effect of 1 kilograms/kwh, PV grid-connected power generation of the average emission reduction effect of 0.6 kg/kwh.
By 2020, the cumulative number of PV installations worldwide will reach 195GWp, about 50% of which are grid-connected photovoltaic power generation.
新疆11选5The carbon dioxide emissions achieved by PV in 2000-2020 will be 700 million tonnes, and carbon dioxide emissions in 2020 will be 164 million tonnes, equivalent to 44 million cars or 75 large power plants, which are effective against haze.
