Solar photovoltaic (also known as solar PV) converts sunlight directly into electricity using a technology known as a semiconductor cell or solar PV cell.
The most common form of solar PV cell is typically encased in glass and an aluminum frame to form a solar panel. One or more panels can be installed to power a single light, cover the roof of a house for residential use, or be assembled into a large-scale solar farm generating hundreds of megawatts of electricity.
Solar PV panels are currently the most widespread type of solar PV technology, however other types of solar PV are being developed for targeted applications including PV that can be integrated into buildings, flexible PV and even PV paint.

Solar thermal converts sunlight into heat (also known as thermal energy), which can be used for a variety of purposes including creating steam to drive an electricity generator. This energy can be used to drive a refrigeration cycle to provide solar-based cooling.
There are two main types of solar thermal technologies.
Small scale thermal technology is used to heat space or water (such as in a solar hot water system).
Concentrated solar thermal harvests the sunโs heat to produce large-scale power generation. It uses a field of mirrors to reflect sunlight onto a device called a receiver, which transfers the heat to a thermal energy storage system. Energy can then be released from storage as required.
