What the figures mean
- Watt class sorting, 0/+10 W
- A panel sold as 410 Wp measures between 410 and 420 Wp. REC sorts upward only, so the number on the label is a floor rather than a midpoint.
- Heterojunction cells
- A cell that layers crystalline and thin-film silicon. REC pairs it here with lead-free, gapless assembly, which is why the datasheet calls out the absence of lead in both the cells and the junction box.
- NMOT rather than NOCT
- REC publishes a second set of figures at nominal module operating temperature: 800 W/m2 of irradiance, 20°C air and 1 m/s wind. It is a more realistic rooftop condition than STC, and the power drops from 410 Wp to 312 Wp under it.
- Power density, 212 W/m2
- Watts per square metre of panel. It is the figure to compare when the roof area is fixed and the question is how many kilowatts will fit.
Who it is for
It suits a roof where the panels are on show and lead free construction matters.
Output depends on how the array is designed around your roof, its pitch and direction, and the shading across the day. Our CEC accredited installers assess the roof rather than estimate from an address.
