Power your outbuilding without compromising the roof.
Retrofit solar and battery systems engineered for flat-roof garden rooms, studios and workshops — designed to protect EPDM membranes and reduce energy costs year-round.
A cleaner, safer way to electrify a timber garden room.
Conventional solar installs often rely on heavy ballast or perforating the roof membrane. That can add structural risk, damage waterproofing and shorten the working life of an outbuilding.
Our systems use a non-penetrative, low-profile bracket solution and adhesive mounting approach engineered specifically for flat-roof EPDM structures. The result is a secure, wind-aware system that keeps the roof sealed while delivering reliable daily power.
Hybrid solar + storage packages for everything from plug-and-play workstations to year-round studios and workshops.
Non-penetrative install
No drilling through the roof membrane, helping protect waterproofing integrity and maintaining roof warranty compliance.
Engineered for wind
Aerodynamic tilt and rear deflectors help the array remain stable in exposed conditions without lifting forces.
Weather-smart batteries
Low-temperature battery heating and off-peak charging support year-round performance in colder months.
Traditional roof mounting can create the wrong kind of pressure.
- Heavy ballast blocks can lead to rafter deflection or added strain on lightweight roof joists.
- Mechanical fixings can puncture EPDM membranes and trigger long-term moisture and rot risks.
- Standard batteries may shut down in sub-zero temperatures, which is a problem for winter use.
Self-install or fully managed project support.

| Lighting | 30W | 2 hours | 60 Wh/day |
| Networking & controls | 24W | 24 hours | 288 Wh/day |
| Secondary display | 75W | 1.5 hours | 112 Wh/day |
Common questions from homeowners and installers.
Will adhesive installation void my EPDM roof warranty?
No. Drilling into the membrane is usually what invalidates a warranty. Our non-penetrative mounting approach preserves the roof’s waterproofing surface.
Can strong UK storms lift the panels?
The system uses low-profile geometry and rear deflectors to reduce uplift and keep the array stable in wind exposure.
Do I need an electrician for a larger system?
For systems above 800W or hardwired distribution, we coordinate with accredited electricians and handle the compliance side for you.
