Built for the Swansea housing stock

Swansea solar panel questions.
How much do solar panels cost in Swansea?
A 4 kWp Swansea system typically costs £6,300–£9,200 fully installed, including 0% VAT (until 31 March 2027). Larger systems with battery: £10,000–£14,000.
Do solar panels work well in Swansea?
Yes. Manchester gets ~1,400 sun hours per year. A 4 kWp system generates ~3,200–3,400 kWh annually — typically covering 65–80% of a Manchester family's electricity needs. The system runs on daylight, not heat.
Do I need planning permission?
For most SA postcodes, no — solar PV is permitted development. Conservation areas need a check, which the installer handles before quoting.
