From the actual test data for more than 30 years (1961-1990), Arizona's sunny, high-direct-component, solar power generator system: fixed-angle solar collectors can be increased by more than horizontal installed solar collectors 14% of the output; single-axis horizontal tracking can increase 40.4%, single-axis latitude and longitude angle collector can increase the gain of 51%; and biaxial accurate tracking system to increase 56%. Illustrations of different tracking systems.

European countries generally used incentive policy is "on-grid price" policy, that is, the power company to buy electricity at a price higher than the conventional electricity, the state for more than the normal price of electricity to compensate for the part of the compensation through the green power additional apportioned to Grid sales price to go. With such a law, the installation of photovoltaic power generation users can earn revenue through the sale of green power; bank loans can be recovered in full; photovoltaic cell manufacturers through sales of solar cells to make money; the government reached the purpose of promoting clean energy; The government paid green power additional compensation; through the media's extensive publicity, those who buy green power know that they are to protect the environment and the environment, Energy and sustainable development to make contributions, but also willing to purchase voluntarily.

Germany first implemented the "on-grid tariff" method, and achieved remarkable results, the successful implementation of 100,000 roof plan, photovoltaic power generation installed for many years ranked first in the world. Following the German, Spain, Italy, France, the Netherlands and other European countries have to follow suit, has introduced their own electricity price policy. Now, Australia, South Korea, and even India are also beginning to implement the "feed-in tariff" policy. In the United States, incentives for PV power vary from state to state. Subsidies based on "feed-in tariffs" are limited, with initial investment subsidies, tax incentives, and net electricity meters being used. Obama took office after the financial crisis, the United States launched 800 billion US dollars of the Salvation Plan, including 96 billion US dollars for renewable energy tax compensation, hoping to stimulate the market through renewable energy subsidies.

Japan implemented the installation of photovoltaic power generation system to subsidize the initial investment, the subsidy decreased year by year, from the beginning to subsidize 50%, 10 years, declining year by year, subsidies to zero to zero, 2005, the Japanese rooftop photovoltaic Subsidies for the system are no longer available. In addition to the installation subsidies for PV systems, it also allows photovoltaic power generation systems to "feed back" to the grid, meaning that power companies buy electricity from photovoltaic systems at the same price, similar to the US "net meter metering" method; The original very high, equivalent to 2,0-2,4 yuan per kilowatt-hour electricity, therefore, even if there is no initial investment subsidies, there is still a considerable market in Japan.

The subsidy policy was restarted in 2009 and, starting in January, Japan plans to restore all subsidies to the solar panel industry, the world's fifth largest producer of greenhouse gas emissions reductions. Japan's "low-carbon action plan" in 2020, Japan's total installed capacity of photovoltaic power generation in 2005 reached 20 times to reach our country's "Renewable Energy Law" has been February 28, 2005 approved by the NPC Standing Committee in 2006, 2006 January 1 only to take effect. China's "Renewable Energy Law" is basically the same with Germany's "on-grid tariff" policy means that the initial investment in power generation system by the project developers themselves, the developer through the declaration to obtain administrative license after the construction of photovoltaic power generation projects, Costs and Profits The Company shall purchase photovoltaic power in full in accordance with the reasonable on-grid electricity price (cost plus reasonable profit) by recovering electricity from the sale of photovoltaic power generation systems. Beyond the normal part of the Internet price, power companies do not paste the money, but by the way electricity tariff imposed on the user to share in the national grid.

In 2007, the State Electricity Regulatory Commission promulgated Decree No. 25 of 2007: Measures for the Supervision and Control of Renewable Energies for Power Grid Enterprises, which came into force on September 1, 2007, emphasizing that the power grid enterprises must follow the principle of Renewable Energy Law Priority acquisition of renewable solar powered portable generator directors, and provide grid access services (the cost of grid access system is also included in the national electricity price grid apportioned.) Grid companies to purchase renewable energy electric clock costs incurred higher than in accordance with conventional The difference between the costs of calculating the average price of electricity generated by electricity generation shall be apportioned among the sales electricity price. The Interim Measures shall impose additional charging standards, scope, tariff distribution and balance schemes for renewable energy tariffs, and renewable Energy tariff subsidy application process, electricity price settlement and tariff quota trading program have made clear provisions.
