Uses of Solar Energy

What is Solar Energy?

Solar energy is the solar power absorbed from the sun through solar panels. It is a renewable form of energy on the planet Earth and a readily available form of energy. Since ancient days people have been using solar energy. For example, the use of magnifying glass to produce fire, to generate electricity through solar energy, installation of Photovoltaic cells is required. These cells absorb energy from the sun and convert it to electricity. Below are uses of solar energy in different ways

Uses of Solar Energy

Solar energy is a renewable, inexhaustible and affordable form of energy. There exist two types of solar devices: active and passive. Using solar energy, environmental pollution can be reduced to some extent. One of the cleanest and purest forms of energy. Some of the applications are heating, indoor and outdoor lights, transportation etc. Below are some of the other uses:

  • Uses of solar energy in India
  • Solar energy for battery charging
  • Solar energy for cooking
  • Solar energy for houses

Uses of Solar Energy in India:

India is one of the populated countries in the world and since solar energy is environment-friendly it is best suited. It does not release carbon dioxide. It is an excellent replacement for non-renewable energies as it is an inexhaustible energy source. Rural areas can be benefited with this energy for various purposes like cooking, drying, electricity etc. In India, power generation is costly so solar energy is the best way.

Solar Energy for Cooking:

Using solar energy to cook is simple. Instead of cooking in a conventional oven, cooking in a solar oven will surprise you with the electricity bill. To cook in a solar box you require – thermometer, a box with aluminium foil, pan duct tape, cooking bag and styrofoam insulation.

Solar Energy for Industries:

Industries require electricity at higher levels due to the use of heavy machinery and equipment. The power supply can be given through solar energy. It is also used to protect pipes from corrosion. Using solar energy will keep the electricity bills in control.

Solar Energy for Battery Charging:

Batteries used to play video games etc can be charged during the daylight as a backup in case power cut issues occur. Also, to save electricity you can charge the reserve battery bank in the sunlight throughout the day and use it in the nighttime.

Solar Water Heater

There are two types of solar water heaters to replace traditional water heaters viz, active solar hot water systems and Passive hot water systems.

Active water heater system: There are two types of active solar water heating systems-

Direct Circulation system – They have a pump to circulate household water into the house with the help of solar collectors.

Indirect Circulation – It uses non-freezing liquid to transfer water that flows into the home. Usually used in areas where there are freezing temperatures.

Passive water heater system: They are cheap but less efficient than active water heater systems. There are two types of passive solar water heating systems-

Integral Collector-Storage passive water heater systems – Used in parts of the world where freezing temperatures occur very rare. The solar collector in such a system is integrated right inside the water storage tank. The water is heated when the sun shines directly on the water storage tank.

Thermosyphon passive water heater systems – The solar collector (heats the water) is positioned below the storage tank.

Advantages and disadvantages of solar energy

Sl. no. Advantages Disadvantages
1 Easy to maintain as the maintenance cost is low Requires a lot of space
2 Less electricity bill Causes pollution
3 Development of technology Not cost-effective
4 Renewable source of energy Energy storage is expensive
5 Wide applications
