Household photovoltaic how to make money: international policies and subsidies
The earliest development of photovoltaic countries in Europe, so the international PV model on the current mainstream model has a profound impact.
Internationally, there are currently three types of incentive models for residential distributed PV: the FIT policy, the Net Metering policy, and the Self-Consumption policy .
1) benchmark electricity price policy
Targeted feed-in tariff policy is adopted by all European countries before 2011 policy. In 2000, Germany took the lead in the implementation of the "benchmark electricity price" law, the implementation of the policy substantially boosted the domestic PV market in Germany, the German photovoltaic installed capacity for many years ranked first in the world. Following Germany, other European countries have also started to implement the "benchmark electricity price" law, making the rapid rise of the PV market in Europe, 2007 and 2008, the European PV market accounts for 80% of the world PV market. In this mode, the grid-connecting point is on the grid side, and the grid buys photovoltaic power in full amount at the benchmark grid-connected tariff based on the amount of photovoltaic power generated.
2) Net electricity charge settlement policy
Net Cleaner Pricing was originally implemented primarily in the United States, and 42 states in 50 U.S. states adopted the Net Clearing Method to encourage distributed PV and distributed wind power generation. After 2010, the price of photovoltaic power in European countries has been lower than the retail electricity price of the power grid, and many countries are also beginning to adopt the policy of "net electricity billing." This model requires that the annual electricity consumption be greater than the photovoltaic power generation. Photovoltaic grid-connected point is located in the load side of the user meter, the PV power consumption from the consumer does not measure to save power directly to the power grid retail price; PV reverse transmission push the meter reverse, or two-way measurement, net electricity settlement, that is, Electricity and anti-sent to the power grid in accordance with the difference settlement, settlement period of one year.
3) Since the consumer policy
Germany launched the "self-consumption" policy in 2011 to encourage PV users to use their products for their own use. The principle of the model is "spontaneous use, I power online." Photovoltaic grid-connected point is located in the load side of the user meter, you need to add a photovoltaic meter back to the meter, or the grid meter set to bidirectional measurement. Since the consumption of PV power is not measured, the retail price of the power grid is directly enjoyed by the power-saving mode. The counter-transmission power is measured separately and is settled by the published PV feed-in tariff.
Can be seen that the rapid development of photovoltaic early, can not do without PV subsidy policy. The above three modes are based on the situation in various places, allowing users to enjoy the benefits while contributing to the environment. At present, we also see that in some developed countries in the country, due to the power generation of electricity and other energy sources and the impact of oil prices and coal-fired power prices, the photovoltaic industry has achieved parity in varying degrees of access to the Internet. With the support of subsidies, Good income.
