Long-form pieces on the engineering, the maths and the politics of putting solar on UK roofs. We write these because the questions keep coming up. Most are 5–10 minutes; none have a sales pitch.
Annual generation × grid intensity gives you the number. Sounds simple. Then you have to be honest about manufacturing carbon, regional yield, and a grid that's decarbonising under your feet. We work it through with a postcode-level calculator.
About a fifth of the PV systems we're called out to inspect have something materially wrong. The warning signs we look for first, what they mean, and what to do if you suspect a bad install.
Online sizing tools are a useful first cut. They miss valley flashings, party walls, chimney shadows, and the loft cable-run that actually decides where the inverter goes. What we look at on the survey, and why.
Batteries are oversold to about half the homes they're installed in. We've turned a dozen of these conversations into a flowchart that gets to "yes, now", "yes, later" or "no, not yet" in under a minute.
A working comparison of every supplier's SEG rate, the small print that matters, and the ones that look high until you read the import tariff they tie you to. Updated monthly.
Slate-tone panels, sympathetic mounting, and a planning visual the conservation officer can actually evaluate. A walk-through of three Grade II listed installs and the patterns that worked.
Tell us about the roof, the goal, or the problem. We'll reply by the next working day — usually faster.
