The functionality of Solar Cooler is dissimilar as that of the traditional coolers. The solar energy is harvested and stored in a battery. This battery is in turn connected to the solar cooler for the power source.

Then the water flows downwards from the higher potential towards cooler grass and cotton. The cooler grass and the cotton soaks the water and makes the air cool; even if the potential of water get lower it does not create any kind of hindrance in the smooth working of the solar cooler.

It do not creates the overheads of maintenance or purchasing of pump neither it has to be sent for servicing every season. The concept of solar cooler sounds good and economical hence almost every class of our society can bear its expenses.


• Saving power and electricity.

• Reducing the expenses made on maintenance of cooler by replacing the concept of pump.

• Reducing the overheads creates by the electricity pump to lift the water when the voltage supply is low.

• To reduce the electricity bills.

• Minimizing the need of season wise servicing.

• To enable people of those rural areas which do not have electricity supply to have cool air during summer days.

Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current.

The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells

Photovoltaic (PV) cells are made of special materials called semiconductors like silicon, which is currently the most commonly used. Basically, when light shines on the solar cell a percentage of this solar energy is absorbed into the semiconductor material. This energy now inside the semiconductor knocks electrons loose allowing them to flow freely.

PV cells also all have one or more electric fields that force electrons freed by light absorption to flow in a certain direction. This flow of electrons is an electrical current. Metal contacts on the top and bottom of the PV cell draw that current off to use to power external electrical products such as lights, calculators etc. This current, combined with the cell's voltage (which is a result of its built-in electric field or fields), determines the power (or wattage) that the solar cell can produce
