JA Solar 435W in Scotland.
JA Solar 435W — our standard install panel across 800+ Scottish homes. Tier-1 manufacturer, 30-year linear power warranty, all-black aesthetic.
Built for Scottish homes.
The 435W panel is our default for a reason: it delivers genuinely strong yield in Scottish conditions where average solar irradiance is lower than southern UK. The n-type TOPCon cell technology has noticeably better low-light and overcast performance than older PERC panels — relevant when most Scottish daylight is diffuse. The 30-year warranty matches typical mortgage horizons.
