1) Solar light → It uses the solar cells to recharge it's battery.Solar light mainly used where facility of electricity is not available.

2) Solar water → Water is heated with the heat of sun. In this system water passses with a long black pipe And, a concave mirror is focused at that point. to give more heat.

3) Solar cooker → It also uses the heat energy of sun to cook food.It also contains a concave mirror which focused is fixed at center of a box.The interior of box is coted with black paint to observe more heat.

In solar lights, batteries are charged using solar photovoltaic panels. It is a lighting system consisting of solar panels, LED lamp, battery and charge controller.

Solar water heaters use solar photovoltaic panels to capture sunlight and to heat water. It normally has a thermal panel, a hot water tank, a circulating pump for water distribution and a thermal regulator.

Solar cookers also convert sunlight into heat energy which is used for cooking.
