What roof directions can work for solar?
South-facing roofs are usually strongest, but east-west roofs can still work well. Heavy shading and north-facing roofs need a more careful calculation.
Solar & battery
One fixed quote for the whole job: panels, battery, installation by a vetted team, Worpra inspection, and a battery set up to earn from day one where the numbers stack up.
Why pair them
Solar alone exports your surplus for much less than you pay to import electricity. Add a battery and you keep more of what the panels make, then the battery can earn on top by offering flexibility to the grid.
The calculator starts with conservative assumptions: roughly a third of generation used in the home without a battery, rising to around three-quarters with one.
| Setup | Self-use |
|---|---|
| Panels only | ~35% |
| Panels + battery | ~75% |
| Battery earnings model | £120-£250/yr |
What it costs
System size, roof complexity, scaffolding, consumer-unit work and battery capacity move the final price. Worpra quotes are fixed and itemised after survey, with the assumptions made visible.
Domestic solar and battery installs are currently 0% VAT until 31 March 2027. That is the factual deadline; no countdown timers, no pressure theatre.

FAQ
South-facing roofs are usually strongest, but east-west roofs can still work well. Heavy shading and north-facing roofs need a more careful calculation.
Most domestic solar installs are permitted development, but listed buildings, conservation areas and unusual roof layouts need checking before quote.
The installer handles the DNO process as part of the job, with Worpra checking that the paperwork is present before handover.
