As a result, the tariff (or tariff) may vary depending on the technology, location (for example. B the roof or prince of the ground for photovoltaic projects), the size (residential or commercial scale) and the region. [1] Tariffs are generally designed to decrease over time to track and encourage technological change. [4] As of January 1, 2010, state laws have authorized owners to sell excess electricity to the distribution company. Previously, the owner had not received credit for overproduction during the year. In order to obtain the California Solar Initiative (CSI) rebate, the customer was not authorized to install a system that is deliberately over-produced, which promotes the installation of efficiency measures after solar installation. This overproduction credit has not been made available to some municipal customers, namely Los Angeles Water and Power. In April 2012, 263,274 facilities received a total of 1,152,835 MW of FiT payments. Of this total, 260,041 were devoted to photovoltaics for a total of 1,057,344 MW. [124] Payments are valid for 25 years. A typical photovoltaic installation, which costs $7,500, pays in 7 years and 8 months and generates $23,610 over 25 years.

[125] In February 2009, councillors in Gainesville, Florida, approved the country`s first solar feed-in tariff. [55] The program has been limited to 4 MW per year. In 2011, Gainesville increased solar power from 328 kW to 7,391 kW, or about 1.2% of peak power (610 MW). [130] The program was suspended in 2014 after more than 18 MW were installed. [131] The feed-in tariff was not available in Northern Ireland. Instead, he had a scheme called NIRO (Northern Ireland Renewable Obligation) that you could claim if you install solar panels. You must contact your electricity distributor to get the feed-in tariff. If you sign a contract with your electricity distributor, you must be informed of the amount you pay for each kW/h exported. Ontario introduced a feed-in tariff in 2006 revised in 2009[53] and 2010, from 42% per kWh to USD 80.2/kWh for microeconomic photovoltaic projects (≤10 kW)[55][55] and 64.2/kWh for applications received after July 2, 2010. The ones before that. The application took until May 31, 2011 to install the system to obtain the higher rate. [56] The Ontario FiT program includes a rate plan for large projects up to 10 MW of solar farms at a reduced price.

In April 2010, several hundred projects were approved, including 184 major projects valued at $8 billion. [57] In April 2012, 12,000 systems were installed and the rate fell to USD 54.9/kWh for applications received after September 1, 2011. [58] [59] The 2013 price plan revised solar energy prices to 28-38 usd/kWh. [60] Feed-in tariffs are considered necessary to promote renewable energy sources in the early stages of development, when production is often economically unenforceable.
