Who are the best solar panel manufacturers? What are the best solar panels today in 2019?

Updated: Jul 1, 2019

These are common asked questions by homeowners, installers, distributors, and it is not easy to give a standard answer in every country of the world. 
We can classify these solar panel manufacturers/factories by company history, by product types, by brand reputation, by production volume or installed module volume. There are thousands of solar panel brands worldwide, and there are thousands of answers to everybody. 
However, three key points have to be considered if you want to find the best solar panels: Material quality, panel efficiency, limited product warranty. 
If we only talk about manufacturers’ history, we’d say these brands are the best such as Hyundai, LG, Panasonic, Sharp, Sunpower, First solar who have more than 20 years history in solar business. However, if we classify by production capacity and annual shipment volume, these companies are mainly from China including Jinkosolar, JA Solar, Trina Solar, Longi Solar, Canadian Solar (Canada), Hanwha Q-cells (South Korea), Risen Energy, GCL-SI, Talesun, First Solar (USA), sourced from 2018. 

What are the best solar panels?

In almost all cases, the best solar panels are made with premium monocrystalline solar cells. Monocrystalline cells are made with a single crystal of silicon instead of many silicon fragments melted together, as is the case with polycrystalline cells. This means that the cells are more efficient at converting sunlight to electricity and have a sleek black tint to them. However, it’s important to keep in mind that premium solar panels with monocrystalline cells generally come with a higher upfront price tag.

Who are the best solar panel manufacturers? What are the best solar panels today in 2019?

How do we figure out which of the companies offer the best solar panels with the proper combination of product quality and price? Technically, we have to check the parameters of the solar panels by every manufacturer and compare their main-stream models with other companies main-stream models that can be widely used in projects. There are hundreds of manufacturers data assessed and taken into comparison.
Then it comes out the three key points for choosing the right solar panels from the best solar panel manufacturers.

Material quality

Despite considering the assembling craftsmanship, there are mainly six key components on one single crystalline solar panel (both mono and poly solar panels), including solar cells, EVA film, back sheet, tempered glass, junction box and aluminum frames. Each of the six components’ failure may cause defects to solar panels. So it is very important that your solar panels are composed of the best materials from the Tier 1 material suppliers in this industry. Of course, it is hard for homeowners to get deep knowledge of the solar panel manufacturers' BOM list, but in some circumstances it is possible to inspect only even by naked eye observation on looking of these solar panels.

Solar panel efficiency

Solar panel efficiency refers to how well your solar panel can convert sunlight into usable electricity. The higher the efficiency is, the more power the solar panels will produce. The best solar panels available on the market today are SunPower’s X-Series Residential Solar Panels, which are 22% efficient.

Materials warranty

We’d say that it should be true the solar panels have the longest warranty among all kind of products supplied for people’s application. Did you every use anything with a warranty over 10 years, not even to say 25 years. Manufacturers provide warranty for all kinds of commodities in every industry, some of them are 1 months, some of them 1 years, some of them are 5 years. A solar panel’s materials warranty (sometimes referred to as the product or equipment warranty) protects you against equipment failures due to manufacturing defects or environmental issues.
Most of the solar panel companies provide 10 years limited product warranty, however the best solar panel manufacturers offer more than that. From 10 years to 15 years. Keep in mind that while not taken into account in this rating, solar panels also come with a 25-year performance warranty as well. Manufacturers typically guarantee that their panels will produce electricity at 80-90% of their original output at the end of that warranty period.

How to find the best price on your solar panels

There is not real THE BEST product for everyone. You got to do a lot of study on reviews about the products, and to know more about not only the solar panels, but also other accessories for the system. The best solar panels may not have the best prices for you, it is always determined by the real case of your installation needs and your expectation on how much do you want to invest, how long do you want to get net profit, how much space you got for your roof/land.

Some Tips for your Reference

1. The best solar panels doesn’t mean the cheapest. You got what you pay.
2. Do not buy no-brand cheap products for your system, you may get endless problems in future.
3. Find the proper installer, who are professional in solar energy and well-trained in project installation and maintenance. It is not that much important even if the solar panels manufacturer does not have long history, be sure the one who serve you for projects are reliable and professional.
4. Compare your products’ specification with other big brands that you didn’t choose. 
It is important if you/your installer can get the BOM list of the equipment you buy. Experienced installers know more about the industry and they can proof more about the product quality for you.
