Description
300 W of flexible panel for larger roofs and heavier loads. At 1500 x 990 mm this needs real roof space, but it delivers meaningfully more than a 200 W panel in the shoulder seasons when you need it. 5.0 kg, 3 mm thick, ETFE.
Key points
- For loads a 200 W panel cannot carry — full-time living, laptops, or a diesel heater running through spring and autumn.
- Still only 5 kg — half the weight of a rigid panel of comparable output.
- Check the roof first — 1500 x 990 mm is a large single footprint. Two 200 W panels are often easier to place, and shading one does not take down the whole array.
- ETFE front sheet for UV resistance.
