9 Best Solar Panel Manufacturers Review in 2021 – (Updated Guide)

Choosing the right solar panel for your household is not an easy ride.

From the performance and efficiency to the price and the quality, there are many factors you need to take into account when making a decision which one will best fit your requirements.

The fact that there are more than one hundred solar panel manufacturers on the market makes the decision-making the process even harder.

To help you choose the best quality solar panel for your home, we did an in-depth analysis of the market and created a list of the top solar panels in the world.

We also outlined the best solar panel manufacturers in 2021 and categorised them according to a variety of criteria.

1- LG Energy

LG Energy


LG Energy is a world-leading and top-selling solar panel in the world and for good reasons. Its panels have a premium range of quality, very high performance and are incredibly reliable.

LG Energy solar panels offer 25-year product and performance warranty and are very popular in Europe, USA and Australia.

Neon 2 and Neon R modules use high-grade N-type cells and are undoubtedly one of the most popular solar panels in Australia.

Overall, they are highly rated among customers not only because of their impressive look (they have black anodised aluminium frames) but also because their construction quality is of the highest standard.

Unlike other manufacturers who produce a range of mono and poly-crystalline panels, LG produces exclusively mono-crystalline cells which are highly efficient and have a lower degradation level.

On top of that, LG also uses Lily technology to decrease light-induced degradation.

LG offers a small range of modules:

  • Mono X Plus – 300W
  • Neon 2 – 330-335W
  • Neon R – 360-370W

Strength & Durability

What differentiates LG from the rest of the manufacturers is the fact that its solar panels have extremely strong double-wall aluminium frames on all modules.

They have 6000 Pa rating on the front side and impressive 5400 ratings on the rear side for wind loading.

Quality & Performance

LG uses two EL flash tests to make sure no cells with defects get through during the production process.

These cells have an extremely long term performance in terms of low light-induced degradation. This improves the overall performance and adds value to the quality.

It also increases energy generation with 86-88% capacity remaining even after 25 years.

According to the latest research conducted by DNV LG, an independent testing organisation, LG Mono X is rated as a “top performer”.

Warranty & Service

Like SunPower, LG offers both a 25-year product and performance warranty while most other manufacturers only provide a ten-year product warranty period.

This kind of warranty plays a significant role in choosing a solar panel for your home and shows that LG has a high level of confidence in their products.

  • LG Performance Warranty
  • LG Mono X – 25 years to 86%
  • LG Neon 2 – 25 years to 86%
  • LG Neon R – 25 years to 88%
  • LG Product Warranty

How to Choose the Best Solar Panel on the Market?

There are a few essential factors you need to consider when choosing a solar panel that will meet your requirements:


When industry insiders speak of panel efficiency, they mean the amount of sunlight that reaches a solar cell that is converted into electricity.

For conventional silicon-based panels, this is typically around between 14-22%.


Every panel has a different wattage, or power, rating. This signifies the amount of power a panel can generate and is usually between 250 and 350 watts.

Higher wattage panels are often more efficient, but also more substantial in size and pricier.


Every panel has a different wattage, or power, rating. This signifies the amount of power a panel can generate and is usually between 250 and 350 watts.

Higher wattage panels are often more efficient, but also more substantial in size and pricier.


When choosing a solar panel brand, be careful to make sure that the company you choose will still be around to honour your warranty.

Typically, larger corporations like LG, Panasonic, and Hanwha are safe bets and highly bankable.

Other Important Factors

Other Important Factors

Once you have chosen the solar panel manufacturer, there are still a few important things you need to take into consideration if you want to make the right choice.

Here are some things you need to pay close attention to when choosing the solar panel for your home:

1. Solar System Size

Regardless of how good the quality, performance and overall impact of a solar panel is, you need to think about the space and the capacity of your roof as well as about solar panel installation.

Also, the size of your home and your energy needs play a vital role here.

2. Local Tax Benefits & Incentives

Depending on the country where you are buying the solar panel, taxes and incentives can vary significantly. For instance, New York offers state tax credits on solar panel purchases.

3. Brand Availability

Sometimes you may choose solar panels that are not available in the area where you live.

Brand availability in your area. Sometimes your local solar companies may not sell the brands of solar panels that are your first choice.

4. Company History

The longevity and reputation of the panel manufacturer play a part in our recommendations.

What good is a warranty if the company goes out of business before they get a chance to honour it? T

hat’s why it’s imperative to look for the manufacturers with a stable track record in the solar industry.

5. Solar Panel Aesthetics

What good is an efficient and top-performing solar panel if it doesn’t have the design that would go well with the rest of your home?

More and more people are looking for well-designed, aesthetically pleasing solar panels.

This is particularly the case in neighbourhoods with some HOA requirements for solar arrays, or for a home that would need panels facing the road.

Many homeowners prefer black panels when comparing solar panels because black panels are the most elegant ones and usually fit comfortably into the surrounding.

However, there are various types of black panels to be aware of.

Most silicone cells are either dark blue or black. These cells are the squares that make up the face of the solar panels. The space between these cells is called backsheet.

To make solar panels even more appealing, manufacturers are making much sleeker solar panels where the space between the cells is also black.

Finally, considering the frame colour is essential. Most solar panel frames are anodised aluminium and come in silver or black.

Choosing a black frame can enhance the look of your system greatly. You may be interested in getting “all black” panels, where the structure, backsheet, and cells are all the same black colour.

Furthermore, there are some solar panel manufacturers like Sunpreme and Trina Solar which manufacture frameless solar panels without backsheet.
