The U.S. Large-Scale Solar Photovoltaic Database provides the locations and array boundaries of U.S. photovoltaic facilities, with capacity of 1 megawatt or more.
In simpler words, the first U.S. patent for solar panels! World-renowned physicist Albert Einstein published a paper on the theory behind the “photoelectric effect,” which officially proved how the sun creates energy through solar cells. This paper went on to win the Nobel Prize in 1922.
The late 2000s was a crucial time for the growth of solar energy. Global investment in clean energy exceeds $100 billion, with solar energy as the leading clean energy technology for venture capital and private equity investment. The solar tax credit helped to create unprecedented growth in the U.S. solar industry from 2006 to 2007.
1954 Photovoltaic technology is born in the United States when Daryl Chapin, Calvin Fuller, and Gerald Pearson develop the silicon photovoltaic (PV) cell at Bell Labs—the first solar cell capable of converting enough of the sun's energy into power to run everyday electrical equipment.

While experimenting with metal electrodes and an acidic solution, nineteen-year-old French physicist Alexandre Edmond Becquerel creates the first solar cell. This solar cell was known as a photovoltaic
USPVDB releases generally lag installations by more than a year, due to the release times of underlying data and the effort required to digitize facilities. See more details on the release. Join the USPVDB
Modern solar energy development in the United States dates back to 1954 when scientists at Bell Laboratories patented the first silicon solar cell. Since then, solar energy has
The first projects in New Mexico''s program came online, four years after the program was originally established. The utility-scale segment installed 9.7 GWdc in Q3 2025, increasing 26% year
The project established the feasibility of power-tower systems, a solar-thermal electric or concentrating solar power technology. In 1988, the final year of operation, the system could be dispatched 96% of

In the United States, 14,626 MW of PV was installed in 2016, a 95% increase over 2015 (7,493 MW). During 2016, 22 states added at least 100 MW of capacity. Just 4,751 MW of PV installations were completed in 2013. The U.S. had approximately 440 MW of off-grid photovoltaics as of the end of 2010. Through the end of 2005, a majority of photovoltaics in the United States was off-grid.
Department of Energy Since 2008, hundreds of thousands of solar panels have been installed across the country as more and more Americans choose solar energy for their daily lives. Investments from
A photovoltaic cell, also called a PV or solar cell, is a device that converts light (radiant) energy directly into electrical energy. PV cells are usually made from silicon.
Ranking 2nd in the nation, Texas has 48.2 GW installed and is expected to continue to grow 76% by 2030, surpassing California. Over the last decade, industry prices have dropped 42% in Florida,
