The Verdict

The decision to choose the QCells Q.MAXX BLK-G4 390-400 or REC TwinPeak 2 Mono Series solar panels ultimately comes down to several factors, such as cost efficiency, design and aesthetic preferences, power output and quality standards.

We like the slightly longer product warranty, greater efficiency and max power output offered by Qcells but for lower-power solar systems, there is not much to choose between both brands.

Homeowner estimates show Qcells solar panels cost between $3.46 to $4.72 per watt, making them one of the most affordable investments for home solar energy. Qcells is undoubtedly a premier choice for residential solar power systems! Expect REC panels to come in at a price range of $3.38 to $5.38 per watt for higher-power solar systems, but still excellent value for money.

It’s important to remember that when making big consumer decisions, such as choosing between QCells and REC solar panels – take the time to do your research properly and decide which option is best for you and your solar system needs.

In many cases, the deciding factor may not be price alone but rather the weight or size of each panel and the space available.
