Monocrystalline solar cell
In this context, "solar energy" refers to energy that is collected from sunlight. Solar energy can be applied in many ways, including to:
* Generate electricity using photovoltaic solar cells.
* Generate electricity using concentrated solar power.
* Generate electricity by heating trapped air which rotates turbines in a Solar updraft tower.
* Generate hydrogen using photoelectrochemical cells.
* Heat and cool air through use of solar chimneys.
* Heat buildings, directly, through passive solar building design.
* Heat foodstuffs, through solar ovens.
* Heat water or air for domestic hot water and space heating needs using solar-thermal panels.
* Solar air conditioning
