Finding the best solar panels for your home can feel like a daunting challenge. There are over a hundred different brands of solar panels and other solar devices on the market at any given time. In this article, we will discuss how solar panel manufacturers make quality products and who makes the best solar panels.

The best solar panels:
- LG, Panasonic, REC and Sunpower are considered among the leading solar panel manufacturing companies.
- Make sure to consider efficiency, price, and warranty when comparing solar panel options.
- Register contact information with Intech Energy to compare solar installation quotes with high quality solar panels.
Best solar panels to install at home:
There are many solar panels available in the market to purchase and install. Among all the companies that are currently manufacturing solar panels, the top names that are often mentioned with the best solar panels on the market are:
- SunPower
- LG
- REC
- Panasonic
- Q CELLS
- Canadian Solar
- Longi Solar
- Jinko Solar
- Trina Solar
All in all, SunPower, LG, REC, and Panasonic make some of the best solar panels in 2020 due to their high efficiency, competitive pricing, and 25-year warranty. These companies' products combine durability and reliability with premium protection and reasonable prices, making them some of the best solar panel brands available.
In most cases, the best solar panels are made with high-end monocrystalline solar cells. Monocrystalline cells are made from a single crystal of silicon instead of many pieces of silicon melted together, as is the case with polycrystalline cells. This means the cells convert sunlight into electricity more efficiently, plus they come in a sleek black color. However, it's important to note that high-end solar panels with monocrystalline cells typically cost more than polycrystalline cells.
The best solar panels ranked by performance:
Solar panel efficiency is a measure of how well it converts sunlight into electricity. Based on maximum module efficiency only, here are the top 5 manufacturers making the best efficient solar panels:
| STT |
Producer |
Panel efficiency |

The best solar panels ranked by temperature coefficient:
The solar panel temperature coefficient is a measure of how much a solar panel's production is lowered at high temperatures. Based only on the lowest temperature coefficient available in the solar panel spec, here are the 4 best solar panel manufacturers:
| STT | Producer | Effect of temperature on power output |
| 1 | LG | -0.26 |
| 2 | REC | -0.26 |
| 3 | Solartech Universal | -0.27 |
| 4 | SunSpark Technology | -0.28 |
| 5 | SunPower | -0.29 |
Best solar panels ranked by physical warranty:
The solar panel's physical warranty (or equipment warranty) protects against equipment failure due to environmental factors or manufacturer defect. Based only on the longest physical warranties available from solar panel manufacturers, here are the best solar panel manufacturers:
- LG (25 years)
- Panasonic (25 years)
- Silfab (25 years)
- Solaria (25 years old)
- SunPower (25 years)
- Q CELLS (25 years)
- REC (25 years)
- Mission Solar (25 years)
- Acidec (25 years)
- Certainteed Solar (25 years)
- Winaico (25 years old)
As shown above, all the top solar panel manufacturers rated by physical warranty offer the same 25 year warranty period. For reference, the industry standard for solar panel physical warranties is 10 years.
How Intech Energy developed the ranking of "best solar panels"
When looking for the best solar panels for your home, you should consider the panel's performance, quality, durability, and warranty. There are three key specifications that can help you as you make your decision: solar panel efficiency, temperature affect power output and panel warranty. To develop our ranking of the best solar panels, Intech Energy evaluated these metrics for all solar panels offered by the leading manufacturers in the solar panel market. Solar.
Solar panel efficiency
Solar panel efficiency refers to how efficiently your solar panel can convert sunlight into usable electricity. A higher efficiency rating is better, as it means your solar panel can convert more of the sunlight it captures into electricity. The best solar panels available on the market are SunPower's A series residential solar panels, which have a maximum efficiency of 22.8%.
The coefficient of influence of temperature on the generating capacity of the panel
The temperature coefficient tells you how well your solar panels will perform under real-world conditions. Solar panels are like any other type of electronic device: they work most efficiently when they are kept cool (ideally around 25°C). The temperature coefficient tells you how the solar panel's performance will degrade on hot summer days. For every degree above 25°C, your solar panel's power output will decrease by a temperature factor. Lower temperature coefficient is better.
For example, LG's model LG400N2T-J5 has a temperature coefficient of -0.3%/°C. This means if the temperature of your solar panel increases by one degree Celsius (from 25°C). to 26°C), then the power output will decrease by 0.3%. If the temperature increases by 10 degrees Celsius to 35°C, the solar panel will generate 3% less electricity. Although 35°C may seem high to you, remember that the surface of your roof can be much hotter than the air around it when the sun is down.
Physical Warranty
Whether you're buying a new TV, a car, or solar panels for your roof, you should expect the manufacturer to stand behind their product with a strong warranty. Your solar panel's physical warranty (sometimes called a product or equipment warranty) protects you against equipment failure due to manufacturing defects or environmental problems.
Most companies offer a physical warranty of at least 10 years, but the best solar panel manufacturers will cover equipment failures for 15 or even 25 years. Many of the manufacturers in our ranking offer more than 10 years of physical warranties.
Keep in mind that while not included in this rating, solar panels also come with a 25-year performance warranty. 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 for your solar panels
If you want the best solar panels on the market, you will have to pay a higher price. The solar panels listed above have received the top ratings of many reviews, but the “best" solar panels are not always the right fit for your home. If your roof is small and you don't have a lot of space for your system, investing in the most efficient, high-performance panels can help you get the performance you need. However, if you have enough space for a larger system, installing slightly less efficient panels can give you the performance you need at a more competitive price. Consider all factors before deciding to choose solar panels for your home.
