What is Solar Energy?
Solar energy is the natural source of energy from 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
Important 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
- Solar water heater
1. 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 from this energy for various purposes like cooking, drying, electricity, etc. In India, power generation is costly so solar energy is the best way.
2. 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.
3. 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 reaction. Using solar energy will keep the electricity bills in control.
4. 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.
5. 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
|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|

Frequently Asked Questions – FAQs
List some technologies that involve the harnessing of solar energy.
Some common technologies that involve the harnessing of solar energy include photovoltaics, artificial photosynthesis, solar thermal energy, solar heating, and solar architecture.
What are solar cookers?
Solar cookers are devices that use sunlight for the drying or cooking of food. These devices can also be used for pasteurization. Common types of solar cookers include panel cookers, reflector cookers, and box cookers.
What is solar distillation?
Solar distillation is a process that can be employed to convert brackish water and saline water into potable water. This can be done with the help of a solar still.
What are the primary applications of solar energy?
Solar energy is a renewable, inexhaustible and affordable form of energy. It can be used to cook food, heat water, and generate electricity. Furthermore, electrical energy generated from solar energy can be stored in solar cells.
List any 3 uses of solar energy.
Solar energy can be used to cook food with the help of solar cookers. It can also be used to convert saline water into drinkable water with the help of a solar still. Finally, solar energy can be converted into electrical energy to power a wide spectrum of devices with the help of a photovoltaic cell.
