An insolation map of the United States with installed PV capacity, 2019. A 2012 report from the National Renewable Energy Laboratory (NREL) described technically available renewable energy resources for each state and estimated that urban utility-scale photovoltaics could supply 2,232 TWh/year, rural utility-scale PV 280,613 TWh/year, rooftop PV 818 TWh/year, and CSP 116,146 TWh/year, for a ...

Brazil began to install solar energy on a massive scale starting in 2017, quickly becoming the Latin American country with the most solar energy installed. The total installed solar power in Brazil was estimated at 21 GW at October 2022, generating approximately 2.48% of the country's electricity demand.
The number of days of sunlight allows the potential of bringing solar power to much of Africa without large scale grid infrastructure. [15] The distribution of solar resources across Africa is fairly uniform, with more than 85% of the continent's landscape receiving a global solar horizontal irradiation at or over 2,000 kWh/(m 2 year).
The following outline is provided as an overview of and topical guide to solar energy: Solar energy is radiant light and heat from the Sun. It has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar ...
The NREL solar program had a budget of around $75 million as of 2009 [81] and develops research projects in the areas of photovoltaic (PV) technology, solar thermal energy, and solar radiation. [82] The budget for Sandia's solar division is unknown, however it accounts for a significant percentage of the laboratory's $2.4 billion budget. [83]

In 2023, solar power generated 5.5% (1,631 TWh) of global electricity and over 1% of primary energy, adding twice as much new electricity as coal. [ 4 ] [ 5 ] Along with onshore wind power , utility-scale solar is the source with the cheapest levelised cost of electricity for new installations in most countries.
