#2. Solar Power Technologies

Solar energy is free and present in abundance. It is about 2 lakh times of the energy produced daily on earth through other sources taken together. All we need are technologies to harness it for our benefit and the sake of a sustainable future.

There are 3 types of solar power technologies majorly used to produce electricity in past years

  1. Photo-Voltaic Solar Power
  2. Thermal Solar Power
  3. Concentrated Solar Power

Photovoltaic Solar Power Technology

Photovoltaic solar power is the energy that is produced by harnessing solar energy using photovoltaic power plants. In solar photovoltaic systems, a device called solar panel is used to generate electricity to run our appliances such as solar pumps, solar ac, solar street lights etc.

At present, solar photo-voltaic energy is the most popular and most common technology in solar compared to thermal and concentrated solar technologies.

Solar PV power was invented in 1839 by Alexandre-Edmond Becquerel. When discovered, the technology was not much welcomed but today, it became the most cost-effective solar technology.

Now anyone can install solar energy at home, office and businesses, as it starts from small capacities such as 1kW at reasonable prices. Governments are also providing incentive schemes and subsidy on solar to make it more cost effective. 

There are further three types of photovoltaic solar systems. Let’s have a quick look.

#1. On-Grid Solar System

On-grid solar systems are the type of solar systems that can be used with the grid, that is, the conventional source of energy. In simpler words, by installing an on-grid solar system, you can power load with grid electricity as well as with solar electricity.

The working principle is, the appliances are powered by the solar system when sunlight or solar electricity, to be specific, is available. In case of unfavourable weather or at night, when the system cannot generate enough solar electricity, the system draws power from the grid.

The most important benefit of using this system is net-metering. It allows you to sell the excess electricity produced back to the grid. On the other hand, the disadvantage is, you cannot store the electricity generated.


#2. Off-Grid Solar System

Off-grid solar systems are solar power harnessing setups that do not require grid electricity to power the appliances. They are grid-independent and capable enough to bear the load of the entire house single-handedly.

The working principle is, the appliances draw power from the solar system when the system is producing electricity absorbing the sunlight.

To supply power at night or in unfavourable weather conditions, the system is equipped with a battery that stores the excess electricity produced.

#3. Hybrid Solar System

Hybrid solar systems are the most versatile kind of solar system. They are equipped with the latest technology to serve best to all the needs of the customers. They are packed with the features of both– an on-grid and an off-grid solar system. 

Hence, with a hybrid solar system, you are allowed to use net-metering in case you want to earn by selling electricity. 

While you can have a battery as well in case you need to store the energy produced.


Thermal Solar Power Technology

The word thermal is concerned with heat so this technology is heat dependent. Solar thermal power plants are used to generate power by using energy from the sun to heat liquids at a high temperature.

This technology converts energy from one form to another, that is, from solar to thermal. These systems focus the sun’s rays to a point using solar collectors so that appropriate high temperatures can be obtained. This heat can be used for several purposes including electricity generation by rotating turbines using the heat waves on a large scale.

The smaller level applications of solar thermal power are mentioned below.

  1. Solar water heater
  2. Thermal power plant
  3. Solar cooker
  4. Space heating
  5. Pool heating

Concentrated Solar Power Technology

In a concentrated solar power technology, the sunlight or the solar energy, coming from the sun, is concentrated to serve the purpose. Concentrated solar energy systems generate solar energy using mirrors or lenses to focus a large area of sunlight over a small area.

As a result, high-intensity heat energy is produced at that small point. This heat is used to run conventional steam turbines or power generating engines. The concentrated thermal energy in the CSP plant can be used for electricity generation directly or can be stored for future consumption.

#3. Why Switch to Solar?

Going solar is the best way to save the environment from rising crises. As a renewable CO2-free power source, the environmental impact of solar energy is much lower than other power generation methods. 

The effect is mainly related to the production and supply of special materials and metals required for the production of solar panels

Hence, you must go solar to save the earth. If it doesn’t convince you satisfactorily, here is another reason that you’ll love it.

It is, adopting solar systems and solar energy as the main source to fulfil your energy needs, you can earn thousands while reducing the cost of your electricity bill.
