Roofs we've already done.

The ones we'd point you at first.

Every one of these is ours, with the panel, inverter and battery named. If a quote won't tell you what's actually going on your roof, that is worth noticing.

01 Bradley Stoke Solar, battery and backupJuly 2026Eight days on site

Fig. 1 · Forty-four of them

Twenty-one kilowatts, three phases and a plan for the dark

The one that keeps going in a power cut

Forty-four panels across a big stone roof, feeding a three-phase hybrid, wired with proper backup built in. Most batteries sit there doing nothing the moment the grid drops. This one runs through a UPS and EPS setup, so the site keeps working while the street waits for the lights to come back.

• 44 Longi 480W panels, 21.1kWp in total
• Ecoflow 15kW three-phase inverter
• 10kWh of battery storage
• UPS and EPS backup, wired to carry the site through an outage

Still on when the street isn'tWired for backup rather than left to trip out, so an outage stops being a closed afternoon.

02 Brabazon, Filton New build retrofitJanuary 2024Two days on site

Fig. 2 · The old array and the new one

The developer fitted panels. Nobody fitted a battery.

Making a new build's solar actually pay

New builds on the Brabazon development arrive with solar on the roof and nowhere to put what it makes, so a bright day mostly goes to the grid for pennies and comes back at teatime at full price. We added a second array on flat-roof frames, wired into the inverter that was already there, then AC coupled a battery to the whole lot.

• Extra panels on a flat-roof mounting system, alongside the original array
• Wired into the existing inverter, so the developer's kit stays put
• myenergi Libbi battery storage, 10kWh
• AC coupled, charging from the original panels and the new ones together

AC coupling is the point of this one. It bolts a battery onto a system that already works instead of tearing out a perfectly good inverter, which on a house this new would be an expensive way to solve the wrong problem.

Fig. 3 · Trays before panels

The tiles were coming off anyway

In-roof, because the timing made it cheaper

Sixteen panels across the north and south faces. The north roof was already due to be re-tiled, so instead of buying a roof full of tiles and then covering them over with panels, we set the panels into the roof on GSE trays. The array does the job the tiles would have done up there, and nobody paid twice for the same square metres.

• 16 JA Solar 460W panels, 7.36kWp across two roofs, north and south
• GSE in-roof trays, set flush into the roof rather than sitting on top
• Sunsynk 5kW hybrid inverter
• 16kWh of Fogstar battery storage

A north-facing roof will always generate less than a south-facing one. It earned its place here because the tiles were coming off regardless, which is exactly the sort of thing worth working out before anyone decides where the panels go.

04 Almondsbury Solar and batteryJuly 2026Four days on site

Fig. 4 · Rails down, mesh on

Two pitches, two angles, one system

The one the battery earns its keep on

Fifteen panels split across two faces of the roof, nine looking west at a 37 degree pitch and six south-west at 25. Different angles peak at different times, which spreads the generation across the day rather than piling it into one lunchtime lump the house cannot drink. Bird protection went on at the eaves before we left.

• 15 Canadian Solar 455W TOPCon panels, 6.83kWp
• EcoFlow Power Ocean 6kW single-phase hybrid inverter
• 10.2kWh of usable LFP storage, two 5kWh units
• Renusol VS+ mounting, SolaSkirt bird protection, UPS socket by the board
