About product

REC 375W Alpha HJT Solar Panel is a 120 cell monocrystalline module, which is made with heterojunction cell technology that reduces temperature coefficients and eliminates LID.REC 375W Alpha HJT provides higher efficiency and energy yield, even at higher temperatures.The solar panel shows an industry-leading 21.4% efficiency, which makes it an ideal solution for rooftop installations.

  • 375W Power Output
  • 120 Cell, Monocrystalline, Half-Cut Technology
  • 21.4% Module Efficiency
  • N-type technology
  • 1000 Volts Max Voltage
  • High power density of 20.2 W/ft2
  • MC4 connectors
  • Black frame, white back

High Efficiency of up to 21.4%

Great power output and great energy yields are achieved with the help of half-cut cell and heterojunction cell technology, which greatly improves flow of electricity current. REC 375W Alpha HJTsolar panel is equipped withsSpecial anti-reflective glass, which increases light transmission for higher power.

Quality and Reliability

REC 375W Alpha HJTsolar panel features unique advanced cell connections reducing thermal stress on the cells for long-term durability. The manufacturer's automated production improves efficiency and reliability, which explains the lowest warranty claims rate across the industry.

We’ve just finished constructing the system and launched it. It’s a bizarre feeling to have a little solar farm on your roof. The shipment was fast and our order was handled very professionally. Thank you very much!

I’ve been using these panels for half a year now. These aren’t my first panels, but these are certainly much more powerful than what I used back in the days. i chose them cause they age slower, so my children could make use of them in the future.

Good day. I’m not sure how to check if my roof can bear these panels?

Your installer has to inspect the roof before constructing a system. The inspection will determine whether or not you need a new roof for that.
Ok, 375W is goof, but how much power output will I have in 25 years? or in 10 years?

REC panels lose only 0.24% per year. This rate is among the best in the industry. You can expect to have over 92% of the initial power output in 25 years.
Are these Chinese?

REC is a Norwegian company. Their panels are currently made in Singapore.
