solar light → It use 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 use 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.

And, in last a plane mirror is also at a top, it protect the heat From sun to go out of box.

NOTE→ they all use the heat energy of sun to produce energy.

A solar lamp is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel.

solar power has many advantages such as Solar power is pollution free and causes no greenhouse gases to be emitted after installation. Reduced dependence on foreign oil and fossil fuels. Renewable clean power that is available every day of the year, even cloudy days produce some power.

Solar water heating is known as the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications

while a solar cooker is known as a device which uses the energy of direct sunlight to heat, cook or pasteurise drink and other food materials.

Most of the solar cookers work on the basic principle: Sunlight is converted to heat energy, that is retained for cooking. They typically require more frequent reorientation to the sun, but will cook more quickly at higher temperatures, and can fry foods.

beside advantages Solar cooker has following disadvantages You open your solar oven, put in a casserole, close the lid and return in a few hours to retrieve it, fully cooked. You've used no fossil-fuel energy in the process, and because food cooks at a moderate temperature in a solar oven, it retains just enough moisture to be delicious.
