Solar panels comparison

(silfab, Hanwha q, Sunpower, and LG solar Panels Comparison)

Finding the best solar panel is challenging because it relates to your solar system’s efficiency, durability, and productivity.

A standard comparison between brands will help you find trustworthy solar panels for your needs.

You have to compare the efficiency, features, costs, and warranty with the brand history to explore a trusted solar panel’s brand model.

We performed some market research to understand how brands and manufacturers compete.

In this writing, we present solar panels comparison for different brands, including Silfab, Hanwha Q, Sunpower, and LG. Let’s explore more and stand out from the crowd.

Industrial Changes

There has been a drastic change when it comes to competition between solar companies.

For example, many companies have come up, including SunPower, LG, and Solaria. SunPower was the only solar panel producer in the past years, but other companies have come on board.

One exciting thing about the top 10 modules of solar panels is that they all lead when it comes to efficiency.

They all rank 20% and above inefficiency.

That only means one thing, the market for the solar industry is growing dramatically.

The other thing that stands out when it comes to the industry is the warranty.

Most warranties have three core values: Labor, performance, and product. Most companies are now giving warranties of up to 25 years.

Among the top ten solar panels, nine out of the ten offer a 25-year warranty.

Previously a standard solar panel with a 25-year warranty only had a one percent degradation rate with an output performance of up to 80%.

When it comes to the top ten solar panels we have, seven have a degradation ratio of point five percent and 90% output.

That is something to boast of when it comes to solar panels.

The third thing that has also changed in the industry is the labor warranty.

In the previous years, only one company had a labor warranty, and that is SunPower. That has now changed.

Companies like LG, Panasonic, and Solaria have also developed a labor warranty.

A labor warranty means that if your solar panels happen to have a problem, the manufacturing company will send an installer to come and check it out and pay them in return.

That is something too great when it comes to taking care of your employees.

On average, most solar panels have a life span of ten to twelve years. But our top ten solar panels have a guarantee of 25 years of excellent efficiency, performance, and productivity.

Solar Panels Buying Guide

You have already decided to go solar, and the first thing you need is solar panels. Before purchasing solar panels for your system, you can look at a buyer’s guide to better understand. 

Here are some key features that will help you select the best solar panel for you.

Solar Panel Type

Monocrystalline and polycrystalline are two types of solar panels available in the market. Comparing the cell types, you can select the most efficient solar cells that will produce more power.


Solar panel sizes and wattage should be flexible for each other. A standard solar panel comes with perfect size based on the capacity. It is better to find a small panel with decent productivity.


A solar system can not provide sufficient power without accurate wattage. Before installing the system, you must compare electricity needs and solar panels’ productivity.


The best solar panel comes with a manufacturer warranty. A quality solar panel will last at least 25 to 30 years. Most companies offer 10 years of warranty for efficiency and 25 years of warranty on the panel. 


Don’t go for an affordable price. It might be a reason to get low-quality products. Find solar panels with the best features and prices. Then you will have the quality product at a competitive cost.
