Great efficiency

REC 370 Alpha Black Series solar panel reaches an efficiency of 21.2% – much higher than conventional modules. This model generates more energy from a square foot which allows you to use space more efficiently. 

Superb performance in low-light conditions

Even when the weather conditions are far from perfect, REC panels perform very well. According to Norwegian engineers, when the irradiance levels decline from standard 1000 W/m² to 100 W/m², the REC 370 efficiency still doesn’t fall below 90%. 3 bypass diodes decrease the effect of shading on the power output.

Outstanding reliability

REC 370W panels come with black frames from anodized aluminium and polymeric construction of a backsheet ensures high resistance of a PV module to any possible hazards. The maximum test load of a panel reaches 7000 Pa or approximately 146 lbs/sq.ft — much higher than a standard for solar panels.

Low degradation rates

The REC 370W solar panel barely ages over the years. This PV module loses no more than 0.25% per year. After 25 years in service the panel is guaranteed to retain 92% of its initial power output.

20 year product warranty and 25 year performance warranty

REC traditionally offers strong warranties for its product. The panels from Alpha Black Series are backed up with 20 year product warranty and 25 year linear power output warranty. REC engineers guarantee that this model retains 92% of its power output after 25 years.

Appearance matters with Alpha Black

On top of being efficient and resilient REC monocrystalline panels look great. The all-black design makes panels look stylish on top of any building. Panels come with a black aluminium frame. Solar cells are protected by 3.2 mm tempered glass with anti-reflection surface treatment

I liked the service. the calculator really helped in sizing the system and the package arrived quite quickly. As far as the panel goes, time will tell, but it looks really good.

The panel is worth its money. i checked and it barely loses power even when it's super cloudy here.

Me and my husband decided to buy panels as a long-term investment project. The staff of A1 was really nice and helpful. In the end I picked this model, mostly because of the looks and its durability. The package arrived safely, the installation is complete – so far everything is working perfectly.

how long does delivery take?

Hello! Estimated delivery time is 4-7 days.
Hello. Does this panel produce DC or AC?

Good day. The REC 370 panel generates direct current (DC) under the sun. You would need an inverter to turn it into alternating (AC).
Is it Chinese?

REC headquarters are located in Singapore and Norway. The panel itself is made in Singapore.
