Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies:
Spain is one of the first countries to deploy large-scale solar photovoltaics, and is the world leader in concentrated solar power (CSP) production.
Solar power accounted for an estimated 10.7% electricity in Germany in 2022, up from 1.9% in 2010 and less than 0.1% in 2000.
Financial incentives for photovoltaics are incentives offered to electricity consumers to install and operate solar-electric generating systems, also known as photovoltaics (PV).
Solar power has a small role in electricity production in the United Kingdom.
Solar power consists of photovoltaics (PV) and solar thermal energy in the European Union (EU).
Solar power in Japan has been expanding since the late 1990s. The country is a major manufacturer and exporter of photovoltaics (PV) and a large installer of domestic PV systems, with most of them grid connected.
Solar power in Romania had an installed capacity of 1,374 megawatt (MW) as of the end of 2017. The country had in 2007 an installed capacity of 0.30 MW, which increased to 3.5 MW by the end of 2011, and to 6.5 MW by the end of 2012. However, the record year of 2013 was an exception, and new installation fell back from 1,100 MW to a moderate level of 69 MW in 2014.
The Polish energy sector is the fifth largest in Europe. In 2023, the country consumed 167.52 TWh of electricity, a 3.44% year–on–year decrease from 2022. Out of this, 76.61 TWh came from hard coal, 34.57 TWh from lignite, 22 TWh from wind energy, and 13.65 TWh from gas, with the remainder coming from other sources, such as solar, biomass, and hydropower.
Renewable energy in the Czech Republic describes the renewable energy related development in the Energy in the Czech Republic.
The Czech Republic had almost two gigawatts (GW) of photovoltaic capacity at the end of 2010, but installed less than 10 megawatts (MW) in 2011 due to the feed-in tariff being reduced by 25%, after installing almost 1,500 MW the year before. Installations increased to 109 MW in 2012. In 2014, no new installations were reported.
Solar power in France including overseas territories reached an installed capacity figure of 11.2 GW in 2020, and rose further to 17.1 GW at the end of 2022. Government plans announced in 2022 foresee solar PV capacity in France rising to 100 GW by 2050.
Solar power in Mexico has the potential to produce vast amounts of energy. 70% of the country has an insolation of greater than 4.5 kWh/m2/day. Using 15% efficient photovoltaics, a square 25 km (16 mi) on each side in the state of Chihuahua or the Sonoran Desert could supply all of Mexico's electricity.
Solar power in South Africa includes photovoltaics (PV) as well as concentrated solar power (CSP). As of 2023, South Africa had over 2700 MW of installed PV solar power capacity in its grid, in addition to 500 MW of CSP. Installed capacity is expected to reach 8,400 MW by 2030.
Solar power in Belgium reached an installed capacity of 9.9 GW at the end of 2023, an increase of 1.8 GW from 2022.
Under its commitment to the EU renewable energy directive of 2009, France has a target of producing 23% of its total energy needs from renewable energy by 2020. This figure breaks down to renewable energy providing 33% of energy used in the heating and cooling sector, 27% of the electricity sector and 10.5% in the transport sector. By the end of 2014, 14.3% of France's total energy requirements came from renewable energy, a rise from 9.6% in 2005.
Solar energy in Poland includes the production of solar thermal energy and solar photovoltaics. By the end of 2021, there were around 3,000,000 square metres (32,000,000 sq ft) of installed solar thermal collectors which in Poland are primarily used for heating up household water.
Renewable energy in Greece accounted for 29 percent of its electricity from renewable sources in 2021. By 2030, renewables are expected to have a capacity of 28GW, and exceed 61 percent of Greece's electricity consumption. This is a significant increase from 8% of the country's total energy consumption in 2008. By 2022, Greece occasionally reached 100% renewables for a few hours. The target for 2050 is a capacity of 65GW.
Solar power in Switzerland has demonstrated consistent capacity growth since the early 2010s, influenced by government subsidy mechanisms such as the implementation of the feed-in tariff in 2009 and the enactment of the revised Energy Act in 2018. By the end of 2022, solar photovoltaic (PV) capacity had reached 4.7 GW, a notable increase from the 0.1 GW recorded in 2010. Concurrently, the contribution of solar power to electricity generation also rose, climbing from 0.1% in 2010 to 6.2% in 2022.
Under the original 2009 Renewable Energy Directive Ireland had set a target of producing 16% of all its energy needs from renewable energy sources by 2020 but that has been updated by a second Renewable Energy Directive whose targets are 32% by 2030. Between 2005 and 2014 the percentage of energy from renewable energy sources grew from just 3.1% to 8.6% of total final consumption. By 2020 the overall renewable energy share was 13.5%, short of its Renewable Energy Drive target of 16%. Renewable electricity accounted for 69% of all renewable energy used in 2020, up from two thirds (66.8%) in 2019.
