Solar power, also known as solar electricity, is the conversion of energy from into , either directly using (PV) or indirectly using. Concentrated solar power systems use or mirrors and systems to focus a large area of sunlight to a hot spot, often to drive a.

“Storage” refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Electrical energy is used to pump water uphill into a reservoir when energy demand is low.

Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. In 1989, the German Research Ministry initiated the first ever program to finance PV roofs (2200 roofs). Module performance is generally rated under standard test conditions (STC): of 1,000 , solar of 1.

Arrays of solar cells are used to make solar modules that generate a usable amount of direct current (DC) from sunlight. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Adjusting for inflation, it cost $96 per watt for a solar module in the mid-1970s. Process improvements and a very large boost in production have brought that figure down more than 99%, to 30¢ per watt in 2018 and as low as 20¢ per watt in 2020. Solar cell efficiency may be broken down into reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency and conductive efficiency.

While the energy storage capacity of grid batteries is still small compared to the other major form of grid storage, with 200 GW power and 9000 GWh energy storage worldwide as of 2025 according to , the battery market is catching up very fast in terms of power generation capacity as price drops.
