Regarded as an industry innovator in split-cell solar module technologies, REC solar panels, without leveraging on price, are beginning to earn a reputation as an option which possesses severely good value. Therefore, what particular elements have defined the REC product range in 2020 to possess such valued qualities without devaluing the product by price?

.Manufacturer:  REC Group.

Series: TwinPeak 2, N-Peak, Alpha.

Variants: Multicrystalline, Monocrystalline, Heterojunction. 

It starts from the bottom. Unlike many alternatives, no matter your preference, each REC Solar module offering now possesses similar guarantees as to what’s available in the top model. A sign of confidence and refinement across the entire range.

Beyond such guarantees though, design, performance and efficiency specifications are a class above the industry average as is discovered when reviewing each REC Solar panel.

Note; Residential 60-cell (or equivalent) solar panels considered only.


The first evolution to the original Intersolar award-winning solar panel from 2015 is the REC Twinpeak Series 2. High-quality multicrystalline cells dispel the debate that mono, in general, is better than poly.

Comparing the REC Twinpeak Series 2 against many alternative manufactured monocrystalline solar panels by specification unveils a solar module built to outperform beyond standard test conditions.

The multicrystalline REC Twinpeak series 2 solar panel is best suited for those who require refined quality solar components with an impeccable reputation. Possessing an exceptional warranty and as one of the more affordable options in the REC range, the REC Twinpeak series 2 could very well be considered one of the best multicrystalline solar panels available.

Two key product offerings now exist with the REC monocrystalline product line, the Twinpeak 2 mono and the N-Peak. However, despite the face value P-type vs N-type mono cell differences, the N-peak possess additional reinforced qualities which is beneficial for installations in certain climates where extreme loading factors exist.

Model Qualities Rank Detail
Twinpeak 2 mono
305-325W, White back sheet, 120-half cut mono p-type cells
4.2 superior
305-330W, White back sheet, 120-half cut mono n-type cells
4.3 elite

Heterojunction cell.

Pioneering yet again, REC Solar panels are now set to compete in the industry-leading efficiency stakes with its highly-evolved Heterojunction (HJT) Alpha series solar panel.

Model Qualities Rank Detail
REC Alpha
360-380W, 120 half-cut cells with REC heterojunction cell technology
4.8 outstanding

Overall score at the bottom of this post. 

Cutting-edge efficiency and design attract a price to match. Desirable as it may be, the Alpha Series solar panel by REC is best suited for those who require ultra-high power density from a limited space.  One of 2020’s most impressive solar panels.


Possessing an elite multicrystalline solar module, by design, is a rarity in the modern world of solar and a testament to the range of REC solar panels available in 2020 which have evolved from this now base model.

No matter the selection criteria though and module choice, the severe value within REC Solar panels as a range for many is a resounding 25-year product and performance warranty (when utilising an REC Certified Installer).

With such resounding manufacturer assurance and elite product specifications, the affordability is exceptional within each particular efficiency class.
