Where to buy kit in the UK

Specialist suppliers, what to buy where, and what to avoid.

Specialist off-grid suppliers — best for panels, controllers, batteries and advice:

Bimble Solar — the DIY community favourite; good-value panels and LiFePO4
Photonic Universe — wide range, complete kits, good documentation
Sunstore — kits and components
12V Planet — superb for cable, fuses, connectors and 12V accessories

Screwfix / Toolstation — conduit, clips, consumables, hand tools.

Amazon/eBay — fine for brand-name controllers (Victron, EPEver) and cable sold by reputable sellers; treat no-name lithium batteries and "1,000W panel £60" listings as the fiction they are. For used panels, eBay can be a genuine bargain — panels degrade slowly and ex-farm panels often have years left.

Rough price anchors (mid-2026): rigid panels £0.50–0.80/W · 100Ah 12V LiFePO4 £200–450 · 40A MPPT £80–180 · 500W pure sine inverter £60–120.
