A Deep Dive into Solar Panel Grades in India

Follow us on:

Before going into India’s solar energy capabilities, one has to learn about the different levels of power gradings for solar panels. Understanding each level provides customers with a more detailed explanation of percentage efficiency in terms of using solar as a power. 

In this article, you will learn everything there is to know about the power grade system, from Grade A high-efficiency solar panels in India to Grade D which is the lowest in modern production solar cells still on sale today.

Grading System Unveiled: A, B, C, D

Today, there’s a lot of confusion about different power grade solar cells. If there is any deviation, the cell will fall into its own Grade B category; but since indeed many defects may cause a solar cell at Grades C, D etc. this classification is in fact highly complex.

Indian solar panel associations rank their products according to performance, efficiency, and quality. Each grade – from Grade A at the top down to Grade D at its bottom – reflects a solar cell’s potential to convert sunlight into electricity and the overall panel durability.

Grade A Solar Panels

The output efficiency of Grade A solar cells, which is between 18-20%, is very high. Their reliability makes them highly desirable in the market; once one has been installed it will work for several years without trouble and only then produce less energy than during its earlier years of operation. Now how can you tell that a solar product is in Grade A?

A Grade A cell has no visible defects, such as cracks, scratches, etc. Their outer edge is also perfect – symmetry of colours, crystals, etc. In it, the filling factor of the CVC is more than 0.7, which means a positive energy coefficient in electricity production. 

Grade B Solar Panels

With an efficiency of 14-16%, Grade B solar cells are considered entry-level ones.

These may not be the best of products but they are reliable and are suitable for projects with budgetary constraints.

Grade C Solar Panels

The performance of Grade C solar cells is basic, while the output may be between 12% and 14%. Low energy demand applications often have them matched up with this form of cell. And it also costs relatively little.

Grade D Solar Panels

They offer only limited efficiency and are an affordable option (less than 12%). Grade D panesl are appropriate in the case described above since it is also the cheapest, given the size and the cost restrictions of the project.

Significance of Solar Energy Grading

Understanding Solar Panel Grades enables you to pick the ones which fit your project conditions best: efficiency, cost and potential life performance.

Solar panel manufacturing:

All about quality. Specifically, it is centred on solar cell manufacture. The quality of  manufacture influences the power grading offered to a solar panel. This involves factors such as purity of components and precision in production.

Navigating the solar landscape: Making an informed decision:

These are points to take into account when considering the degree of efficiency as well. Grasp them for each project to assure maximum return on its investment.

Classification of solar power guarantees not only energy-efficient output but also ensures optimal performance in a renewable energy landscape.
