Best Solar Panels in India – Reviews & Buyer’s Guide

Top Solar Panels Buying Guide

The solar panel technology is gathering strong momentum in countries like India. The reasons for the rising demand are mounting power bills and rising levels of air pollution in the country. Installing solar panels not only reduces electricity bills to a great extent, but also plays a major role in reducing air pollution. The need for a solar system also depends onone’s use case and objective If someone is looking for power backup, he should choose an off-grid solar system, but if someone wants to reduce his electricity bill, he should go for an on-grid solar system. As cost and technology improvement gather pace around the technology, solar panels have become more and more popular in our country. Today, installing a solar system on your rooftop or compound could multiply your property value.

Top 10 Best Solar Panels in India 2019 – 12V & 24V

What is a Solar PV System?

A Solar system comprises of solar panels/ modules, charge controller, inverter, battery and balance of systems. Solar panels are the most important component of a rooftop system and account for 50% of the total system cost. Inverters are the powerhouses of the solar system that store the excess energy generated by the panels to be used later when there is no sun. These account for nearly 25% of the total system cost. Balance of Systems include accessories like wires, cabling, mounting structures, junction boxes etc.

What are solar panels made of?

Solar panels are made up of solar cells and involves a total of 20-25 machines. It involves cutting, stringing, taping, connection, testing, lamination, fixing junction box, cleaning, inspection, etc. processes to make a complete solar panel. You can read about the detailed process here:

How does Solar PV System work?

The panels absorb sunlight during the day and stores the excess power generated to be used during night time. When sunlight falls on the panels, a reaction takes place converting solar energy into electricity. The higher the energy falling on an atom, the easier is the excitation of electrons that contribute to the flow of current and higher current is produced.

Types of Solar PV Systems?

Off Grid Solar System – An off-grid solar system typically consists of solar panels, inverter, mounting structure, power backup, grid box and balance of systems. An off-grid solar system works independently of the grid and should be preferred where power problem is acute and there is no reliable power supply.

On Grid Solar System – An on grid solar system works together with the power grid. It is generally used when your power consumption is high and you want to reduce your electricity bills. In an on grid system there are no batteries.

How much does the solar PV system cost?

A 1 kW off-grid solar system will cost you around Rs. 1-1.25 lakh. A grid connected system of the same size will cost Rs. 75,000-90,000. It costs around Rs. 60,000- Rs.1 lakh to install an off-grid solar system (1 kVA system – two batteries and three solar panels). An inverter battery costs around Rs. 20,000.

A 1 kW solar system needs 80 – 100 square feet area for installation.

Can you use solar PV with your existing inverter battery system?

Yes, you can use the same. You have to buy solar panels and charge controller only.

Are there any subsidy available for rooftop solar PV?

Yes, various central and state subsidies are available. However, they are more readily available for educational institutes, hospital, government/ public establishments.

What are the comparison between Mono vs. Poly solar panel?

Polycrystalline silicon or Polysilicon is a material consisting of multiple small silicon crystals. Polycrystalline silicon is highly pure (as much as 99.9999% pure) form of silicon and is much costlier. Monocrystalline solar cells on the other hand are made of single crystal polysilicon and have higher efficiency than those made from multicrystalline polysilicon.

Which brand should you choose?

Leading solar panel brands in India are Loom Solar, Luminous, Microtek, Exide, Havells, Vikram and Waaree.

Here is the list of solar panel criteria based on we can choose the best solar panel brands:-

  1. Branding
    • Sales, Service and Maintenance after buying product – A good company will always be prompt in providing all the above mentioned services.
    • Installation Service – A good solar panel supplier will provide prompt installation services. You do not have to stress about the installation process or worry about the connections.
  2. Quality
    • Warranty – Solar panels are a long-term investment and customers want to work with a bankable partners, hence warranty plays an important role in determining who will be the solar panel seller. In India, panels are available with 10 years product warranty and 25 years power warranty.
    • Efficiency – The efficiency of a solar panel is calculated by the amount of sunlight it converts into electricity per unit of area. Leading global solar panel companies like SunPower and Trina Solar have efficiencies of 24.1% and 17.8%. Indian companies like Loom Solar has more than 19% efficiency.
    • Durability – The durability of a panel is estimated by its strength to endure heavy rains, hailstorms, high winds, excessive pressure, etc. Most of the leading solar panel brands are designed to sustain these extreme conditions.
    • Temperature Coefficient – Temperature coefficient is measured as the effect of high temperatures on functioning of solar panels. The lower the temperature coefficient, the better.
    • Reviews – Last but not the least, is the reviews available on the internet. Once you have narrowed your preferred brands, you can zero down your product with the help of customer reviews and testimonials available for these brands.
