REC Solar panels: the complete review

Reading Time: 4 minutes

REC Group is Europe’s largest manufacturer of solar panels, and has offices in Europe, the United States, Asia, and Australia. The company was founded in Norway in 1996 and manufactures its solar panels in Singapore. REC solar panels are an increasingly popular option in quotes to shoppers comparing solar offers on the EnergySage Solar Marketplace.

How REC’s solar panels compare to other panel manufacturers 

There are four key metrics that you should review as you evaluate solar panel quality: efficiency, performance, warranties, and price. EnergySage has developed REC’s solar panel reviews for each metric to help make your solar decision easier. We’ve also created a comparison of REC’s solar panels against other leading panel manufacturers that are frequently featured in offers to homeowners and businesses shopping for solar on the EnergySage Solar Marketplace.

Efficiency

The term “solar panel efficiency” refers to how well a solar panel captures sunlight and converts it into useful electricity. In the same conditions, a high-efficiency solar panel will produce more electricity than a lower-efficiency panel of the same size. For this reason, a higher efficiency rating is generally preferable.

The efficiency of your REC solar panels will vary depending on the specific model that you choose for your system. Panels in REC ’s product line have an efficiency rating of 16.5% to 21.7%.

Performance (Temperature Coefficient)

For this portion of EnergySage’s REC solar panel reviews, we use the temperature coefficient to evaluate solar panel performance. The temperature coefficient is an indicator of how well your solar panel can handle less-than-ideal conditions. Solar panels, like other electronic equipment, perform better when they are kept cool (ideally around 25° C/77° F). The temperature coefficient tells you how much your panel’s performance will change during hot sunny summer days.

For every degree above 25° C (77° F), your solar panel’s electricity production will decrease by its temperature coefficient. For example, REC’s REC280TP panel has a temperature coefficient of -0.39%/°C. This means that, if the panel’s temperature increases by one degree from 25° C (77° F) to 26° C (79° F), its electricity production will decrease by 0.39%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 3.9%.

Your solar panels will likely see more than a few hot and sunny days over the course of each year, so ideally, they will have the lowest temperature coefficient possible. As you can see in the graph below, REC solar panels have temperature coefficients ranging from -0.37 to -0.26.

Warranties

Whether you’re buying a TV, a car, or solar panels, the manufacturer should stand behind their product with a strong warranty. A solar panel’s materials warranty (sometimes referred to as the product or equipment warranty) is a guarantee from the manufacturer that they will replace your panel if it fails as a result of manufacturing defects or environmental issues.

Most solar panel manufacturers offer a 10-year materials warranty, but some higher-end solar panels come with a 12, 15, 20, or even 25-year warranty. REC  offers a maximum of a 20-year warranty against any defects in their solar panels.

How much do REC Solar panels cost?

For many homeowners, the final decision around the solar equipment you choose rests on cost. The total price you pay for a solar energy system with REC’s solar panels will vary depending on the other equipment (such as inverters and mounts) used in the installation, as well as the characteristics of your roof.

To identify the range of prices for REC solar PV systems, we analyzed quotes including REC solar panels that homeowners received from installers on the EnergySage Solar Marketplace. Most REC’s solar PV systems are typically priced between $2.62 and $3.18 per watt, which makes them a strong value in the market for home solar.

This means that, for an average 6 kW system, your gross cost (before you subtract any tax credits or other incentives) would be anywhere from $15,720 to $19,080. Additionally, most homeowners end up paying much less than the total gross cost. With the 30 percent federal tax credit for solar, which everyone is eligible for, a 6 kW system with REC’s solar panels would cost anywhere from $11,004 to $13,356. There are plenty of state-level solar incentives and rebates that can help you reduce upfront costs even further. 

REC solar panels may not offer the absolute best efficiency or performance in the solar industry, but thanks to their low price and solid performance, they’re a popular choice for shoppers comparing solar quotes on the EnergySage Solar Marketplace.

How to find the best price on REC solar panels

The best way to determine whether REC offers the best solar panels for your home is to review multiple quotes with different solar equipment options before making a decision. When you compare all of your options on the EnergySage Solar Marketplace, you’ll find the right combination of price and quality that meets your needs.

Many of our qualified, pre-vetted solar installers offer REC solar panels in their quotes to EnergySage users. When registering, simply note in your profile that you’re interested in receiving quotes that include REC solar panels for your home.

    I disagree on your ratings. The MOST important attribute of a panel is the company behind it. What good is a warranty if the company goes out of business. Sunpower should NOT be a premium panel.

    Dear Sir,
    I think the price per watt of REC panel is way too high
    I rather said , for 315w mono twin peak is $277 retailed at most considering 0.6 cts per watts Ex works, do you means the total installed price what consumer pay divided by the sys size

    Where in the Philippines can we order the REC Norwegian panels that supposedly have 50% efficiency when cloudy days and rain. We are in Silang the province of Cavite.
