One of the most significant problems that Indians face throughout the country is power cuts.
Using generators or home inverters is one way of ensuring that your office or home receives continuous power.
Generators can be cumbersome to use and are noisy appliances, as well. It also consumes a lot of fuel.
Home inverters have their limitations, especially when it comes to managing loads.
Installing a Solar energy plant is an ideal solution under such circumstances.
Fortunately, India is blessed with abundant sunshine, with most of the places getting more than 300 days of bright sunshine.
Secondly, solar energy is available for free. Therefore, harnessing this natural source of renewable energy should be the ideal solution to the power shortage problems that India faces today.
- Installing a Solar Photovoltaic (Solar PV) system can address the issue of power cuts efficiently.
- Here are the benefits of installing solar PV systems for generating electricity for your domestic and commercial needs.
- Installing a solar PV system is a one-time investment.
- The system requires minimal maintenance while providing a continuous supply of electricity to the household or commercial establishment.
- The principal raw material, i.e., sunlight, is available for free. Your solar PV system harnesses this free natural resource for producing electricity.
- Apart from generating electricity, this system also helps to reduce your consumption, thereby helping you to manage your electricity bills.
- The modern-day solar PV system can also supply electricity to the primary grid, whereby you become a generator of electricity rather than being a consumer. It helps the respective states to meet their power supply shortfall.
- The Government of India has introduced subsidies, thereby encouraging people to use solar energy for their electricity consumption.
- The household gets a continuous supply of electricity. There are provisions to store the electricity generated in a battery that is connected to a home inverter. Therefore, your dependence on the primary grid for your electricity supply reduces drastically.

In this article, we shall discuss solar PV panels and understand the factors that one should look for when purchasing them. This buying guide will help in understanding the concept of solar PV panels.
Why do you install solar panels?
Generally, people install solar PV systems for the following three reasons in India.
Compensate for the power cuts and reduce the overall electricity consumption from the primary grid
Store excess power generated in batteries for use when solar energy is not available
Inspired by neighborhoods
The concept of supplying power to the primary network is not yet available on a large scale in India.
States like Tamilnad, Andhra Pradesh, and Karnataka have started implementing the concept of net metering. However, it is yet to gain popularity.
Solar PV Systems – Different types
Generally, there are two types of solar systems in India.
Off-grid Solar System
Here, the solar system does not connect to the primary grid. The solar system comprises solar panels, mounting structures, inverter, power back-up, and the central AC panel.
This system works independently of the network. It enables the storing of energy in the battery banks that can be used to supply current to the household using the domestic inverter.
Such solar systems are in place where the main electric power supply is unreliable. These systems have great use in areas witnessing acute power cuts.
The on-grid solar system works along with the primary grid. This system does not need to store electricity in battery banks.
It is generally handy when your overall electricity consumption is high.
Using the solar system for your electricity needs during the day reduces the total consumption from the primary grid. Thus, you end up saving on your utility bills.
Hybrid Solar System
There is a third type of solar system known as the Hybrid solar system. It is a combination of the off-grid and the on-grid solar systems.
This system uses battery banks and inverters like the off-grid systems. The beauty of the hybrid solar system is that it connects to the grid, as well.
Thus, it ensures an uninterrupted supply of power even during power cuts at night. The energy stored in the batteries come handy under such circumstances.
This system is such that you might not need the electricity from the primary grid during the day, as solar energy can take care of your needs.
At night, the energy that is stored in the batteries can take over. Therefore, you might even end up having surplus power that you can supply to the primary grid.
However, you should have a net metering system if you wish to provide power to the network. This system enables you to save the maximum amount of power and money, as well.
Types of Photo Voltaic panels
Generally, there are three types of photovoltaic panels, of which the first two named ones are the most commonly in use in India.
Mono-crystalline solar cells are made of single-crystal polysilicon. In the manufacturing of the cells for mono-crystalline panels, silicon is formed into bars and cut into wafers.
This type of panel has the highest efficiency. At the same time, they are the most expensive, as well.
Poly Crystalline or Multi Crystalline Panels
This type of solar PV panels is made from multiple, small silicon crystals. The method of manufacturing the poly-crystalline panels require the melting of fragments of silicon to form wafers.
