Commercial Overclad Solutions

Revolutionary solar cladding solution

At Solfit, we’ve taken a fresh look at how to tackle old, leaking, or failing commercial roofs. Instead of stripping everything out or layering on more metal, our overclad solar system gives you a smart, sustainable upgrade, fixing the roof and powering your building. With Solfit’s award-winning in-roof panels, you can overclad asbestos, fibre cement, or metal roofs with a watertight system that does double duty – protect your property and produce clean energy.

How it works

Solfit creates a second skin of solar overcladding over the old roof to make it watertight.

Solfit’s patented system interlocks like traditional overcladding but with a twist. Instead of metal sheeting, our overclad is made of durable, fire-rated solar panels.
Every module locks tight, creating a seamless, watertight surface. Light, strong, and fast to fit, even on fragile roofs.
Compatible with asbestos, fibre cement, and metal.

Fund your over clad solar with a Power Purchase Agreement (PPA)

A Power Purchase Agreement (PPA) offers a simple, low-risk way to fund a Solfit over clad solar installation with no upfront capital cost. Through a PPA, a third-party funder designs, installs, owns and maintains the solar system on your building, while you purchase the clean electricity it generates at a fixed rate – typically lower than your existing energy tariff.

This approach allows commercial and industrial sites to reduce energy costs, cut carbon emissions and improve sustainability credentials from day one. At the end of the agreement, ownership of the Solfit over clad system can transfer to you, delivering long-term value from a high-quality, roof-integrated solar solution.

Real stories from satisfied customers

Our asbestos roof was leaking into the production and office areas of the building, a roofing contractor quoted to remove and replace the roof, but the disruption and cost meant it wasn’t feasible. We decided on 400 SolFit panels to cover the entire roof, making it completely watertight, generating 170kwp and providing 260mm of insulation which increased our EPC rating.

Matthew GarnettJames Robertshaw

We considered a traditional re-roof but chose Solfit's over clad solution for its added benefits; our roof is now completely watertight and we’re also benefiting from lower energy bills from a more sustainable energy source.

Appleby Creamery

The initial idea was to over clad with metal and then install traditional solar on top but after the structural survey it was clear the structure wouldn’t take the additional weight. Solfit’s system came in just under on the weight loading, so it was really the only option available. We had 4000 panels installed and 500 transparent panels to let the light through. As most installs are built around the mounting equipment with the laying of panels at the end, this was a very welcome alternative that provided a real sense of job satisfaction.

Rainhill

The Solfit over clad system is a game change for commercial property; a roof fix that pays for itself, that is compatible with asbestos, makes it the clear choice for leaking and old roofs. Clear payback, no business downtime, and a boost in a business’ green credentials. If you have a leaky roof Solfit is a no-brainer.

Ed FrostTemple Solar

We’ve been installing commercial solar for over a decade and there was always a certain percentage of projects would have to walk away from as there wasn’t an appropriate solution. Solfit’s over cladding system is now our go to solution for leaky or asbestos roofs.
