Owner-side, not installer-side
We are not selling panels, so a recommendation not to proceed is as available to us as any other conclusion.
Independent assurance for solar PV, from roof suitability to post-installation inspection.
Condition inspections, thermal imaging and installation health and safety assurance for solar PV and low-carbon projects — commissioned by owners and funders who want an opinion that is not the installer’s.
Renewables & Solar
A solar array is a twenty-five year commitment bolted to a roof you already own.
Rooftop PV changes the loading, the drainage, the access and the fire behaviour of the building it sits on. Most disputes we see start with a suitability question that was never properly asked, or an installation signed off by the company that did the work.
We look at the roof and the array as one asset. Before installation that means structural and condition suitability, access strategy and a realistic view of the constraints. After installation it means verifying that what was specified is what got built, and finding the defects before they become outages.
What the service covers
- Roof suitability assessment — condition, remaining life, loading, drainage and fixing strategy before commitment
- Pre-installation H&S review — access, CDM duties, interface with occupation and the contractor’s arrangements
- Solar PV condition inspection — mounting, fixings, cable management, isolation, labelling and general condition
- Thermal imaging surveys — identification of hot spots, bypass diode faults and underperforming strings
- Post-installation assurance — a check that the installed system matches the specification and the record drawings
- Fire and access considerations — isolation strategy, firefighter access and the practicalities of working around the array
Who it is for
Building owners and investors adding PV to existing stock, funders and asset managers taking on installed arrays, and contractors who want an independent check before handover.
What you get
An opinion with nothing riding on the answer.
Every report is written to be used on site, not filed and forgotten — prioritised findings, plain language and a clear owner for each action.
Roof and array together
The array is assessed as part of the building, including what it does to access, drainage and remaining roof life.
Defects found early
Thermal and visual inspection catches the faults that quietly cost yield long before they trip an alarm.
Common questions
Renewables & Solar, answered plainly.
Can you assess a roof before we commit to an installer?
Yes, and that is the most useful point to involve us. Suitability, access and remaining roof life change the economics far more than the panel price does.
What does thermal imaging actually pick up?
Cell and module hot spots, bypass diode failures, connection faults and shading effects — the underperformance that does not show up as a fault on the inverter.
Do you cover battery storage too?
We review the health and safety, fire and access implications of storage as part of the wider installation. Electrical design and commissioning stay with a qualified installer.
