Coastal vs inland solar performance — PVGIS comparison for 5 UK pairs: Brighton (coast) vs Guildford (inland): 1,050 vs 1,020 kWh/kWp (+3%). Plymouth (coast) vs Exeter (inland): 1,010 vs 1,050 kWh/kWp (-4% — Exeter higher altitude). Southampton (coast) vs Winchester (inland): 1,060 vs 1,040 (+2%). Scarborough (coast) vs York (inland): 880 vs 930 (-5% — coastal fog). Swansea (coast) vs Cardiff (inland): 970 vs 980 (-1%). AVERAGE: coastal performs 0-3% better on sunshine hours. HOWEVER: salt spray requires slightly more frequent cleaning (£50-£100/yr extra). Marine environment: ensure IP67 rated panels (all modern panels qualify). Wind loading: coastal installations need enhanced fixings (included in MCS installation standards). NET RESULT: negligible performance difference. Coastal homes should install without concern.

Solar panels are most powerful when combined with an efficient heating system. Heat pumps use solar-generated electricity to heat your home at 300-400% efficiency — making them the ideal partner for solar.
Heat pump installation typically takes 2-3 days and is best planned alongside solar.
