Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the potential to satisfy all future energy needs.
Photovoltaic (PV) solar energy stands out as one of the most prevalent and widely recognized solar technologies. It directly converts sunlight into electricity, providing a flexible and scalable solution for a variety of energy needs, from small personal devices to large-scale power generation.
solar thermal energy (STE) Solar. the conversion of the radiant energy from the sun into heat, which can then be used for such purposes as space and hot water heating, industrial process heat, or power generation. See below. solar thermal energy When a dark surface is placed in sunshine, it absorbs solar energy and heats up.
Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity. It is one of the fastest-growing renewable energy technologies and is playing an increasingly important role in the global energy transformation.
Solar radiation can be converted either into thermal energy (heat) or into electrical energy, though the former is easier to accomplish. Solar energy has long been used directly as a source of thermal energy.
Solar energy has long been used directly as a source of thermal energy. Beginning in the 20th century, technological advances have increased the number of uses and applications of the Sun’s thermal energy and opened the doors for the generation of solar power.

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. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribu…
