Choosing the right solar module for your household or commercial purpose is not an easy task. For choosing the best suitable module one should be aware with the factors related to it. In this article I will make you understand many factors you need to take in account when making a desicion which one will be best to fulfill your requirement from performance to its efficiency and durability I am gonna explain you and every single important factor.

Let’s check out a few leading solar panel brands in India, on the basis of the above mentioned factors.

1. Efficiency

Efficiency is define as the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the ability to do things well, successfully, and without waste. Now to know the efficiency of a solar panel then it 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.

Maximum efficiency of a solar panel is 25%. According to the calculations Loom Solar offers 20% efficency in its solar panels, whereas Luminous only offers 17.11%.

2. Warranty

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.

Loom offers their customers 10yrs of product warranty and 25yrs of linear power performance with 2.5% for 1st yr degradation and 0.67% from 2yr to 25yr, Whereas Luminous offers 10yr warranty on 90% of nominal power and 25yrs on 80% of nominal power, Whereas Microtek offers 1yr on Manufacturing defects and 25 yrs performance warranty.

3. Temperature Coefficient

A temperature coefficient describes the relative change of a physical property that is associated with a given change in temperature.

Let's know about temperature coefficient in Solar Panels

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.

Standard Temperature - 25°

If temperature > 25° then what will happen,

1.Power will drop

2.Voltage will drop, and

3.Current will increase

Loom Solar offers Temp. Coefficient of Pmax (%/°C) : -0.43, Voc (%/°C) : -0.32, Voc (%/°C) : 0.03, Electrical Values measured at STC: 25°C, 1.5 AM, 1000 w/m², Luminous Offers data at standard test condition (STC) Power Tolerence: 0/+5%, Cell Temperature : 25°C

4. Durability

The Ability to withstand wear, pressure, or damage is Durability. 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.

Loom Solar manufactures completely durable panels as it can sustain heavy wind load (2400 Pa) and snow loads (5400 Pa), Hailstrom, excessive pressure, stone, monkey and more. Whereas Luminous also provides Waterproof, corrosion and torsion resistant design offers protection against wind and snow. And Microtek can also sustain heavy wind and snow loads (2400 Pa and 5400 pa), staff, mist, ammonia, blowing sand and half resistant.
