250W MCS Certified Black Semi-Flexible Solar Panel — High-efficiency monocrystalline semi-flexible solar panel with black frame & cells | 250W output | Lightweight & bendable design | Self-adhesive backing option available | MCS certified for UK grants & installations | Excellent low-light & shading performance | Ideal for curved roofs, caravans, boats, motorhomes, portable setups & off-grid applications | IP68 junction box | BROOF(t2) fire class | 10-year product warranty + 25-year power output guarantee (90% at 10 years, 80% at 25 years) | MPN: SELM series (250W variant)
✅ MCS certified for UK solar grants – premium semi-flexible panel for curved or non-standard surfaces
Made in Sweden with high-efficiency monocrystalline cells (up to ~20–21% efficiency). Semi-flexible structure allows gentle bending to match curved roofs or surfaces. Self-adhesive version bonds to bitumen/felt/metal roofs (min pitch 5.7°). Superior shading tolerance & low-light output – ideal for UK weather. Cadmium-free & low carbon footprint.
This 250W MCS certified black semi-flexible solar panel combines premium monocrystalline cell technology with a lightweight, bendable design for installations where rigid panels are impractical. The all-black appearance (black frame & cells) provides a sleek, modern look that blends seamlessly on dark or contemporary roofs – perfect for visible residential or commercial installations. MCS certification qualifies it for UK government incentives (e.g. Smart Export Guarantee) and ensures compliance for professional solar arrays.
Featuring high-efficiency cells with excellent low-light performance and superior partial-shading tolerance (bypass diodes per cell), it delivers reliable energy even on cloudy UK days or when parts are shaded by chimneys/trees. The semi-flexible structure allows gentle bending (min radius ~0.5–1 m depending on model) to conform to slightly curved roofs, caravans, boats, motorhomes or portable setups. Self-adhesive backing enables quick peel-and-stick installation on bitumen, roofing felt or metal surfaces without drilling or heavy frames – preserving waterproofing integrity. IP68 rated junction box and BROOF(t2) fire class ensure safety and durability in outdoor environments.

Frequently Asked Questions
Is this panel truly semi-flexible?
Yes – gentle bending capability allows it to conform to slightly curved roofs or surfaces (min radius ~0.5–1 m depending on exact model) without cracking.
Does it qualify for MCS certification benefits?
Yes – MCS certified, making it eligible for UK solar incentives (e.g. Smart Export Guarantee) when installed by an MCS-registered company.
Can I walk on it?
Yes – shatterproof & crack-resistant design handles foot traffic for maintenance without damage to panel or roof.
How does it perform in shade or low light?
Excellent – monocrystalline cells with bypass diodes provide strong output on cloudy/overcast UK days & in partial shade.
What controller do I need?
Use an MPPT solar charge controller (min 20A recommended for 250W). Contact us for compatible recommendations.
Who installs it?
Qualified roofer or MCS-certified solar installer – ensure proper surface preparation & bonding for long-term adhesion.
What if my roof is curved or irregular?
Ideal – semi-flexible design fits surfaces rigid panels cannot. Min roof pitch 5.7° for water runoff.
