5 Best Solar Panels for an Indian household 2021

Solar panels are the building blocks of any PV ecosystem. They’re the most basic and the least intricate of all PV devices.

A solar panel consists of numerous small converter cells called Photovoltaic Cells. PV cells are responsible for converting the incident sunlight into power. Today, we’ll be looking at the 5 best solar panels in India. A few basics to start with —

How do solar panels work?

The incident sunlight on the silicon-made panels carries some energy. This energy knocks off the valence electrons of the semiconductor. The positive and negative plates juxtaposed upon each other create an electric field. This field aligns the drifting free electrons in a particular order, producing electric current. For a complete explanation, visit the mechanism of solar panels.

If you’ve been longing to get a solar panel for yourself and are undecided on how to choose, you’ve come to the right place. Here, we discuss the criteria for choosing solar panels based on a handful of parameters and rank the best for you.

What do you need to look at when buying a solar panel?


The efficiency of solar panels is the ratio of the incident solar energy converted into productive electric output. Solar panels are usually efficient in the range of 15-20℅. While the values may seem paltry, any panel with an efficiency of 20% would be considered high-end and among the best solar panels in the markets.


Solar panels should be strong enough to last in external environments. Households station them in the open sun, so they must have a good build quality to face high heating, rains, hailstones, and storms. If the panel tears and wears quickly, it’s better you pay a few extra bucks to have one of a good build.

Temperature Coefficient

The temperature coefficient of a solar panel has a direct relation to its productivity and efficiency. With increasing temperature, the efficiency of any solar panel gradually decreases.

If the temperature coefficient of your panel is -0.4/°C at any temperature, it will register a drop of 0.4% in efficiency for every 1C rise in temperature.

The lower the temperature coefficient — the lesser the efficiency loss per unit degree rise in temperature. The best solar panels, thus, have a comparatively low temperature coefficient.

Brand Reliability

Brand reliability is one of the foremost aspects of choosing the best solar panels, or any electronic device, for that matter. Reliable brands have more expertise at building efficient and durable panels.

The cost of the devices also rises proportionally to the reliability. As such, we’d recommend against choosing your preferred panel solely based on brand value. Several small players are coming up with great stuff these days.

Financials of a Manufacturer

Solar systems mean energy security that spans decades. Generally, most solar module manufacturers give a performance warranty of 25 years. The panels, though, run for a lot longer than that. The estimated life of commercial-grade solar panels is 60 years.

Do you see where we’re going? We recommend that you choose a company having enough finances so that the company survives for the duration of Warranty — brand reliability at play, again.

It shouldn’t be the only criteria, though. Many good companies are new and small but offer quality service.

We now proceed to the list of the best solar panels for an Indian household.
