Going solar is one of the best decisions you can make as an individual and for your household. It’s a decision that goes beyond the opportunity to cut down on your utility bills—it’s a major upgrade and a massive step toward a more sustainable lifestyle.


When it comes to making a decision as influential as this one, you must be at your most responsible and pragmatic.


That’s why doing your due diligence will help you make a decision you can stand by for years to come.


You probably already know this, but choosing a solar manufacturer requires lots of research and careful consideration. Today, we compare Qcells with REC Solar in a no-holds-barred review to make decision-making easy for you.


Let’s get started.

Understanding the Differences Between Qcells and REC Solar

Qcells and REC Solar are popular choices when it comes to rooftop solar installations. Equally well-known with considerable global distribution, this comparison between the two is one of equals—for the most part.


Is one better than the other?


Let’s break down how each solar manufacturer performs in terms of the following solar panel KPIs before drawing a conclusion:


Whether you want to save on utility bills or gain energy resilience, the performance of your solar panels will determine if your investment will meet your expectations. Although Qcells and REC are both known for manufacturing excellent solar panels, one’s products perform better than the other.


For simplicity, let’s compare Q.PEAK DUO BLK ML-G10+ and the REC Alpha Pure-R, both of which have 410 Wp. Both models use half-cut cells arranged in a gapless array. Although REC uses HJT cells while Qcell uses monocrystalline ones, the technology is comparable.


Qcell guarantees that its solar panels will work at 86% output efficiency through 25 years of moderate use. For REC, you can expect your solar panels to provide 92% output for the same period.


So, in technical terms, REC panels only experience about 0.25% degradation every year. It’s lower than the average 0.5% yearly rate that most PV panels go through.


In addition, REC also subjects its solar panels to rigorous testing, and only one in every 10,000 such panels has been classified as defective.


As far as performance is concerned, REC’s range of solar panels edges past Qcells.


Now, let’s talk of another critical KPI for solar panels: efficiency.


The Alpha Pure-R has a panel efficiency of 21.2%, and the Qcells model offers 20.6% at most. That only accounts for a 0.6% difference in efficiency—almost negligible.


What’s more interesting is the temperature coefficient of these models. It indicates how much the overall output decreases for every one-degree rise in ambient temperature.


The lower the temperature coefficient, the more efficient a solar panel is, especially in the long run.


With a temperature coefficient of -0.24%/°K compared to -0.34%/°K of the Qcells model, REC undoubtedly comes out the winner as far as panel efficiency is concerned.


Other REC models are generally more efficient than Qcells.


But there’s one thing about Qcells you cannot ignore when planning to make a purchase. Its latest all-black models, like the Q.PEAK DUO BLK ML-G10+ discussed above, are excellent performers in extreme weather conditions.


These solar panels are fortified with what Qcells calls “all-weather technology.” The solar cells are set in premium aluminum alloy frames. These frames can withstand high wind pressures of up to 4000 Pa and snow loads of up to 5400 Pa.


To further fortify efficiency, these models also use the brand’s in-house Q.ANTUM technology. It reduces thermal losses through the back of the panel and ensures the solar cells can absorb as much sunlight as possible. So these panels perform very well under low light and high temperature conditions.


Depending on your location, you can get outstanding performance from Qcells and REC Solar. It’s best to consult with your local solar expert to understand which brand has solar panels that will best cater to your requirements.


Pricewise, Qcells emerges a winner. It costs $2.80 to $2.95 per Watt for installing a Qcells rooftop solar panel. In contrast, REC panels can set you off by $2.90 to $3.60 per Watt.


This means Qcells panels are at least $4,000 cheaper than REC Solar for a standard 8kW set-up that can meet the energy needs of most American households.


You will also break even on your Qcells solar panels quicker than REC Solar. If you’re looking for dependable performance at affordable prices, Qcells should be your top choice.


As any solar user will tell you, a good warranty that covers the product and its performance is non-negotiable when it comes to choosing a solar system. Thankfully, both these brands provide excellent coverage.


Qcells provides a 25-year product and power warranty. You can expect any Qcells solar panel to provide 98% output during its first year of installation. The panels experience a standard degradation of 5% every year after that. But even then, the 25-year product warranty has you covered.


On the other hand, REC provides 20 years of warranty on its solar panels and 25 years of performance warranty. You can extend the product warranty by five years under REC Solar’s ProTrust Warranty plan.


The ProTrust Warranty is exclusive to solar installers certified by REC. You can enjoy support for product, performance, and labor charges.


Both brands clearly provide solid warranty plans. REC outshines Qcells because of the added coverage it provides.

Other Products

Going solar is not just about purchasing solar panels. You also need additional products for a fully functioning setup, like batteries and inverters that you can easily couple with the panels to boost utility.


Unfortunately, REC Solar only manufactures solar panels.


Qcells wins when it comes to providing a foolproof storage solution. With its energy storage systems (ESS) like Q.HOME CORE H3S/H7S, you can have 10 to 20kWh of backup power.


Qcells also offers easy remote monitoring of your solar arrangement through the Q.Home Core app.


You can create your own end-to-end solar energy ecosystem by connecting your solar panel to the ESS and the app. It’s a robust solution so you can utilize solar power to its fullest potential—a winning advantage Qcells has over REC.


We always advise rooftop solar users to supplement their solar array with battery storage. While you can always buy solar batteries or inverters from other manufacturers, getting it all from one company is often more cost-effective. It also makes the process of going solar easy and hassle-free.

Recent developments have shown that both QCells and REC have made significant advancements in their solar panel technologies. QCells has introduced their latest high-efficiency modules, boasting improved performance in low-light conditions and better temperature coefficients, which means more consistent energy output even in less-than-ideal weather. REC, on the other hand, has enhanced their panel durability and long-term performance, ensuring that homeowners get maximum value over the lifespan of their solar installations. These innovations make both brands strong contenders, offering robust solutions for residential and commercial solar needs.

The Verdict

Who wins the battle: Qcells or REC Solar? Given the parameters discussed, Qcells provides a better long-term return on your solar investment. You can build a reliable solar-powered ecosystem for your home for energy independence.


That said, REC Solar cannot be dismissed. If you have no budget constraints and want high-performing solar panels, this company’s rooftop solar solutions are for you.


Make your final call based on which brand meets your energy goals at present and for the foreseeable future.
