Solar power is a major contributor to electricity supply in Australia. As of December 2025, Australia's over 4.29 million solar PV installations had a combined capacity of 45.1 GW photovoltaic (PV) solar power.

Solar power is an important source of electricity in India. Since the mid-2010s, India has increased its solar power significantly with the help of various government initiatives.

Solar water heating (SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes.

Spain is one of the first countries to deploy large-scale solar photovoltaics, and is the world leader in concentrated solar power (CSP) production. Spain is also one of the European countries with the most hours of sunshine.

A community solar project, farm or garden is a solar power installation that is funded by, and provides output credit and tax benefits to, multiple customers including individuals, businesses, nonprofits, and other investors. Participants purchase a share of or subscribe to a certain kW capacity or kWh generation of…

Solar power has a growing role in electricity production in the United Kingdom, contributing around 6.4% of the UK's annual power generation in 2025. As of 2025, on sunny days, it provides over 30% of the UK's power consumption at times.

A photovoltaic power station, also known as a solar park, solar farm, or solar power plant, is a large-scale grid-connected photovoltaic power system (PV system) designed for the supply of merchant power. They are different from most building-mounted and other decentralized solar power because they supply power at the…

China Sunergy CSUN (Chinese: 中电光伏) is a Chinese solar cell products manufacturer based in Nanjing, Jiangsu. The company specializes in creating solar cells from silicon wafers.

Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high-purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process,…

The Discovery Program is a series of Solar System exploration missions funded by the U.S. National Aeronautics and Space Administration (NASA) through its Planetary Missions Program Office. The cost of each mission is capped at a lower level than missions from NASA's New Frontiers or Flagship Programs.
