REC Solar Panels: Comprehensive Review (2024)

Let’s Get to Know REC

REC Group, headquartered in Europe, reigns as the continent’s top solar panel producer, with a global presence extending to the U.S., Asia, and Australia. This Norwegian-born company, established in 1996, is famous for introducing the half-cut cell technology in 2014, a revolutionary approach that enhanced solar panel efficiency by splitting solar cells into two. Their manufacturing hub is located in Singapore.

In 2022, REC unveiled its latest line of solar panels, the Alpha Pure-R series. Now, their product range encompasses four potent solar modules designed specifically for residential use: Alpha Pure-R, Alpha Pure, N-Peak 2, and Twinpeak 4. Thanks to their reliable performance and top-quality build, REC solar panels are increasingly sought after, and they’ve become one of the most frequently quoted and chosen options at 8MSolar

What kind of REC solar panels can you get?

The offerings from REC are diverse, providing a range of top-grade solar panels for both residential and commercial use (though they’re not a standard pick for utility-scale systems). The company currently highlights the high-power Alpha Pure and Alpha Pure-R series as excellent choices for homeowners:

  • REC Alpha Pure-R
  • REC Alpha Pure
  • REC N-Peak 2
  • REC Twinpeak 4

All these solar panel series feature monocrystalline technology, which means they use a single silicon crystal as opposed to numerous fragments used in polycrystalline panels. Though they come with a slightly steeper price tag, these panels offer better efficiency and adaptability to temperature fluctuations.

Diving into the specifics of solar cells, the N-Peak 2 panels from REC employ n-type silicon, whereas the Twinpeak 4 panels use p-type silicon. The key distinction here is that n-type silicon incorporates phosphorus, while p-type silicon is boron-based. The Alpha series from REC provide higher power compared to the N-Peak and Twinpeak series, thanks to their heterojunction (HJT) solar cell technology. This technique delivers superior power density, efficiency, performance, and longevity. Moreover, the “pure” label signifies that these panels are lead-free, implying a smaller carbon footprint and no hazardous leaks when recycling the panels.

Let’s look at how the power output and cell technology of different REC panels stack up against each other:

How do REC solar panels measure up? 

When assessing solar panel quality, there are four primary metrics to consider: efficiency, performance, warranties, and cost. Let’s delve into what each of these entails and see how REC solar panels fare against the competition in the solar industry.

Efficiency 

The term “solar panel efficiency” denotes a panel’s ability to capture sunlight and transform it into usable electricity. Given similar conditions, a high-efficiency panel will yield more electricity than a less efficient panel of the same size. Therefore, panels with higher efficiency ratings are generally preferred.

The efficiency of your REC solar panels will be contingent on the specific model you select. The most efficient panel boasting 22.8% efficiency. In comparison, REC’s product line boasts an efficiency rating between 19.1% and 22.3%:

Performance (temperature coefficient) 

The temperature coefficient is an important parameter showing how well a solar panel operates under less optimal conditions. Like all electronic gear, solar panels operate better when they’re kept cool (ideally around 25°C/77°F). The temperature coefficient provides insight into how much your panel’s performance will diminish on hot, sunny summer days.

For each degree above 25°C (77°F), the electricity production of your solar panel will decrease by its temperature coefficient. For instance, the Alpha Pure-R panels from REC have a temperature coefficient of -0.24%/°C (the best performance). This implies that if the panel’s temperature rises by one degree from 25°C (77°F) to 26°C (79°F), its electricity production will decrease by 0.24%. If the temperature escalates all the way to 35°C (95°F), electricity production will be reduced by 2.4%.

Solar panels will likely endure quite a few hot, sunny days each year, so the lower the temperature coefficient, the better. REC solar panels have temperature coefficients varying from -0.34 to -0.24:

Warranties 

Just as when you’re purchasing a television or a vehicle, the manufacturer should back their product with a robust warranty when buying solar panels. The materials warranty of a solar panel (also known as the product or equipment warranty) is an assurance from the manufacturer that they’ll replace your panel if it fails due to manufacturing defects or environmental factors.

REC provides a 25-year product warranty under their ProTrust warranty on any panels installed by a REC Certified Solar Professional installer, a standard in line with other top solar panel companies such as Panasonic, SunPower, and Q CELLS. However, if you opt for a solar installer that isn’t REC-certified, you’ll only receive a 20-year product warranty, but don’t worry 8MSolar is REC-certified! They also furnish a 25-year power warranty, guaranteeing that their panels will still generate at least 86% to 92% of their initial output by the end of the warranty period, depending on the product series:

How Much to REC Solar Panels Cost?

For many homeowners, the ultimate deciding factor when choosing solar equipment is the cost. The total amount you pay for a solar energy system with REC’s solar panels will depend on other equipment (like inverters and mounts) used in the installation and the features of your roof.

As of now, the average price of solar panels (across all brands and types) ranges from $2.40 to $3.22 per watt. That said, REC solar panels are usually priced slightly higher than the average, reflecting the premium technology and efficiency they offer. On average, you could expect to pay between $2.75 to $3.50 per watt for REC solar panels before applying any incentives or rebates.

Please note that the costs mentioned here are just the average costs of the solar panels themselves and don’t account for other solar equipment costs like inverters, mounting hardware, labor costs, permit fees, potential tariff fees, and other factors that could affect the total cost of a solar power system.

Are you Ready for REC?

Even though REC solar panels might come with a slightly higher initial cost, the investment could pay off in the long run. With their high efficiency, robust warranty, and excellent performance under various conditions, REC solar panels can provide a great return on investment through higher electricity production over the system’s lifetime.

Moreover, the total cost of your solar energy system can also be brought down significantly through various solar incentives. In the U.S., the federal Investment Tax Credit (ITC) allows you to deduct up to 30% of the cost of your solar energy system from your taxes. There are also many state-level incentives and rebates that can help reduce the cost of going solar.

REC Group is a well-established player in the solar industry, and their solar panels are a great choice for homeowners looking for a high-quality, reliable, and efficient solar solution. While they might be a bit pricier than some other options, the long-term benefits and return on investment could make REC solar panels a wise choice for your solar energy system. If you think REC is right for you, and you are looking for a solar installer in North Carolina, give the experts at 8MSolar a call.
