Question

Gather information about solar light, solar water heating system and solar cooker.

Answer 1

Solar light, solar water heating system and solar cooker all work on the energy of the sun. The light operates on electricity from batteries, charged through the use of the solar photovoltaic panel. The solar water heater uses the sun's energy and converts it into electricity with the use of photovoltaic cells and this energy is used to heat up the water. Solar cookers work in the same way as the heat generated by the sun's energy can cook up the food. This is a better and convenient method as compared to traditional methods which involve fuel and gas. These cost low as compared to other methods of electricity and cooking, such as kerosene, natural gas, coal, etc, because the energy of the sun is renewable and free, unlike fossil fuels. The disadvantage is that they may not work at night and their efficiency decreases on cloudy days or in shady areas.
