Rec Solar Panel Range:

REC TwinPeak 4 And 5 Panels

REC’s TwinPeak 4 series panels, the fourth generation, feature a unique design with top and bottom halves. This design ensures that shading on one half does not affect the output of the other, making them more tolerant to partial shade and soiling.

TwinPeak 4 panels offer an efficiency ranging from 19.7% to 20.5% and are accessible in models with power capacities of 360W, 365W, 370W, and 375W.

TwinPeak 5, the fifth generation, is larger and weightier compared to the 4 series. However, it is offered in capacities of 395W, 400W, 405W, 410W, and 415W.

REC Alpha Solar Panels:

The company introduced its Alpha Series solar panels in 2019, claiming it to be the world’s highest-power 60-cell module at that time.

Initially, the Alpha had a panel efficiency of up to 21.7%, while the subsequent Alpha Pure provides up to 22.2% efficiency. It is offered in wattages of 385W, 390W, 395W, 400W, 405W, and 410W.
