Solar Panels Buying Guide

The solar panel is the best alternative way to reduce your electricity bill. But don’t get too carried away by fancy advertising. There are other important factors that you need to consider before choosing solar panels for your home.

Here are the top tips for buying the best solar panels.

1. Manufacturer’s Warranty

When purchasing a solar panel, a warranty is the first and most basic factor that needs to be checked carefully. This might be something very easy for other products like a battery, an inverter, or a charge controller but in the case of solar panels, it’s a bit tricky.

Do You Know: the current produced by a solar panel decreases year after year. This is known as panel degradation and it’s a common phenomenon with any solar panel.

For solar panels, there are 2 types of warranties. The first one is the manufacturer’s warranty and the other one is the performance warranty. The manufacturer warranty as suggested by the name covers manufacturing defects, durability, and other environmental issues. Usually, the period of the manufacturer’s warranty is 5-15 years. This is very important as the solar panel is something that is kept outside hence it needs to be strong enough to tolerate outside issues such as a hailstorm. Do cross-check with your solar panel brand about this period.

Performance warranty, on the other hand, defines the panel degradation rate. Like we said earlier that solar panels’ performance degrades every year. Some manufacturers provide a performance warranty on the power-producing capacity within the next 25 years. This means solar panel performance will degrade year after year but it will not degrade beyond a certain percentage. Usually, this is around a 0.7% drop. Also, the smaller this percentage gets the better it is.

2. Solar Panel Ratings

This shows the capacity of a solar panel to generate current under certain conditions. Solar panel ratings are a useful parameter to compare solar cells. If a solar panel has more rating then it means that it would produce more current compared to any other panel with less rating.

However, if two solar panels have the same efficiency ratings, but different power ratings, then it is very much likely that the one with the greater power rating is bigger in size compared to the other one. Hence, it is necessary to consider other parameters as well.

3. Solar Panel Price

When buying solar panels, the most important factor is the price of solar panels. Everyone wants to buy solar panels at a substantially less price. However, buying less might have some limitations.

Fact: If you are getting something at a considerably lower price than the average, then you might get poor-quality components.

Always check things like components quality, warranty period, installation charge, etc. in detail. In this way, you will get what you pay for.

Do You Know: You can convert your existing inverter and battery into a solar inverter and battery. Check out more details here.

4. Solar Panel Certifications

Solar panel certification is very important especially when you are looking forward to getting a government subsidy on your installation. Always buy solar panels that are (Ministry of New and Renewable Energy) MNRE Approved to avail of government rebates. Only grid-connected projects can avail of government subsidies.

Solar Panels Installation Guide

In Which Direction Should Solar Panels be Installed in India? And why?

When installing solar panels, one of the most valid questions to ask is how exactly can we decide in which direction our panel is supposed to be placed. The answer to this question varies from country to country.

The straight answer to this question for India is — South.

Why should solar panels in India be south-facing?

Our country India lies in the northern hemisphere so when the sun travels, it takes an elliptical trajectory going from east to west having an inclination towards the south, hence to get the maximum quantity of solar energy we have to place our panel accordingly. As you can see, be it summer or winter, the inclination is towards the south.

After the direction, the other important parameter is the tilt angle.

What should be the angle of solar panels in India?

The tilt angle is determined according to the latitude of your position. For example, if you are living in Cochin-Kerala, the tilt angle for your solar panel will be approx. 10-12 degrees. On the other hand, if you want to incorporate a panel in Delhi, your tilt angle will be almost 28-30 degrees.

Before incorporating a panel, we need to ensure that there is no tall obstacle coming in between the sun rays and the panel as the shadow of the obstacle will fall on the panel and will disintegrate its efficiency So the next time you think of installing a solar panel, take out your personal gizmo and check your orientation with respect to the direction and enjoy the benefits of free energy – The Solar Energy.
