Solar panel. Solar panels absorb the sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells.
Solar energy is energy which is created from sunlight, or heat from the sun. Solar power is captured when energy from the sun is converted into electricity or used to heat air, water, or other fluids.There are currently two main types of solar energy technologies:1  solar thermal: these systems convert sunlight into thermal energy (heat). 2  Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). Most solar thermal systems use solar energy for space heating or to heat water (such as in a solar hot water system). 2  However this heat energy can be used to drive a refrigeration cycle to provide for solar based cooling.
