When you've got the roof space and want the output to match, the Flex-Si 310W is the largest panel in the line. It's built to cover more ground and generate more power per install, without giving up what makes Flex-Si worth choosing in the first place: a semi-flexible, low-profile design that mounts flush to slightly curved surfaces with adhesive or grommets — no rack, no rigid frame. A-grade silicon cells inside a weatherproof laminate keep output consistent and dependable, so a single 310W panel can do the work that would otherwise take two smaller ones — fewer connections, less hardware, more usable roof space left over.
