  2. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.

  3. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    This solar power system can generate power in cloudy weather or at night using the heat in the tank of hot salt. The tanks are insulated, able to store heat for a week. Tanks that power a 100-megawatt turbine for four hours would be about 9 m (30 ft) tall and 24 m (80 ft) in diameter.

  4. Concentrated solar power - Wikipedia

    en.wikipedia.org/wiki/Concentrated_solar_power

    Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine (usually a steam turbine) connected to an electrical power generator [2] [3] [4] or powers a thermochemical reaction. [5] [6] [7] As of 2021, global installed capacity of concentrated solar power stood at 6.8 GW. [8]

  5. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Solar air heating is a solar thermal technology in which the energy from the sun, solar insolation, is captured by an absorbing medium and used to heat air. Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications.

  6. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

  7. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    Usually, solar panels are given a lifespan of 25–30 years before they get decommissioned. [178] The International Renewable Energy Agency estimated that the amount of solar panel electronic waste generated in 2016 was 43,500–250,000 metric tons. This number is estimated to increase substantially by 2030, reaching an estimated waste volume ...
