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.

The Comanche Solar Project is a 120 megawatt (MWAC) photovoltaic power station near the city of Pueblo, Colorado. It became the largest solar facility in the state when it came online in late 2016.

Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p–n junction will produce electric current in response to different wavelengths of light.

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.

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. Belgium had 4,254 MW of solar power generating 3,563 GWh of electricity in 2018.

The Solar Ark (ソーラーアーク, Sōrā Āku) is a Japanese arc-shaped solar photovoltaic power generation facility located in Anpachi, Gifu Prefecture The facility is 315 meters (1,033 ft) wide and 37 meters (121 ft) tall, one of the largest solar buildings in the world, and is located in the geographical center of Japan. It can…

Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045. Much of this is expected to come…

A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and the all-inorganic cesium lead halide, are…

Heterojunction solar cells (HJT), variously known as Silicon heterojunctions (SHJ) or Heterojunction with Intrinsic Thin Layer (HIT), are a family of photovoltaic cell technologies based on a heterojunction formed between semiconductors with dissimilar band gaps. They are a hybrid technology, combining aspects of…

Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study:…
