How To Use The Solar Energy

The Sun produces energy through atomic fusion. Atmosphere reflects about 30% of the sun radiation and absorbs 20% of it. The remaining 50% reaches the Earth. Even so, this amount is 170 million times larger than the energy produced by the world's biggest power plants.

We know today, there are multiple uses of solar energy. We use the solar energy every day in many different ways. When we hang laundry outside to dry in the sun, we are using the solar heat to do work, drying our clothes. Plants use the solar light to make food. Animals eat plants for food. And as we learned, decaying plants hundreds of millions of years ago produced the coal, oil and natural gas that we use today.

In the modern solar oven, sun light is used for cooking, using a concave mirror that focus the sunlight on the food or pot. Other types of ovens use a system of flat mirrors for directing the sun rays to the food.

Many households use solar energy for heating the water. The sunlight warms up cold water passing through closed flat panels, called collectors. They function like reverse radiators, absorbing heat for warming up the water. Usually, they are mounted on the roof of the houses, under an angle that allows them as much as possible of the solar energy.

Below is some uses of solar energy :

1 . Heat your home through passive solar design or an active solar heating system

. Generate your own electricity

3 . Heat water in your home or swimming pool

4 . Light your home both indoors and outdoors

5 . Dry your clothes. Use a clothesline to reduce the energy consumed by your clothes dryer

Photovoltaic Systems are frequently the preferred solution for holiday homes, which have no access to the electricity grid. These solar systems are configured to meet power needs less expensively than extending the grid to reach your location.

Solar batteries are electronic devices that use the photoelectric phenomenon for producing power. A sole photocell generate a weak tension, that's why more cells must be bound in a series, so that the solar battery can be used as a source of energy.
