Buying Solar panels could be the single best decision that you have made not only environmentally but also financially. The cost and technology improvements are slowly making solar power plants a viable option not only for large institutions but also for individual buyers. Give yourself a pat on the back for this decision. The next big question is to chose the specific brand of solar panel. There are a large number of companies selling solar components and for a novice this could be a very confusing decision to make, since solar entails a huge one time investment. The final decision will depend upon a lot of factors such as your power needs and a reliable solar partner, who would not only be there to help you with your installation needs but also be around to serve its warranty.
Though it is important to study the technical parameters of a solar panel, the foremost step is to study about the fundamental aspects of the solar panel. Installing a solar system involves a huge amount of investment and it is a lifetime decision for your property. It is therefore, important to think on all lines. Metrics such as efficiency, warranty, temperature coefficient and durability will go a long way in deciding the number of panels required and the vendor, which will in turn determine the total capital expenditure.
Let’s check out a few leading solar panel brands in India, on the basis of the above mentioned factors.
The efficiency of a solar panel is calculated by the amount of sunlight it converts into electricity per unit of area. If a solar panel is more efficient the overall efficiency of the rooftop solar system also increases. Efficiency of panels play a major role in the effective working of the whole solar system and hence prudence must be applied while choosing the same. A more efficient solar panel results in lesser number of panels to be installed and hence will entail less capital outflow.
Tier 1 Chinese players like Trina Solar announced average efficiency of 17.8% for its industrially produced P-type monocrystalline cells while SunPower boasts of achieving new 24.1% solar panel efficiency record.

Choosing a solar panel based on warranty is important as many companies might not be around to honour their promise later. The solar companies are facing constant challenge in the form of declining prices of products and many of the smaller players are finding it difficult to sustain. 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.

#3. Temperature Coefficient
While sunlight is important for the proper functioning of solar panels very high temperatures can lead to degradation. Temperature coefficient is measured as the effect of high temperatures on functioning of solar panels. The lower the temperature coefficient, the better.
Let's know about temperature coefficient,
- Power will drop,
- Voltage will drop, and
- Current will increase
- Power will increase,
- Voltage will increase, and
- Current will decrease
Best solar panels by temperature coefficient
The durability of a panel is estimated by its strength to endure heavy rains, hailstorms, high winds, excessive pressure, etc. Solar Panels in different countries undergo different stress test under varied environment conditions and external pressure. These panels are then given ratings by rating agencies in order for customers to compare and choose from.

The special thing about solar panels is the safety of your battery and inverter. Many company’s solar panels do not provide ampierer supply according to the standard of the battery.

I will never recommend any one to purchase the product from this company. Product quality is no issue. Very poor and worst customer service. Shipment delivered in 14 days without battery and there is no information share with me that battery will despatch separately. No reply in mail whatsapp and saying that will reply in 2 business hours. I have to cancel my ticket due to negligence of service. Now I have to wait another few days or month to purchase battery from other source and need to pay additional freight cost for this.
