Frequently asked questions
Is solar + battery + EV the highest-return combo?
Almost always yes in the UK 2026 — combined annual savings of £1,800–£2,600 are typical for a 4-bed with 4kWp solar, 10kWh battery and one EV.
Should I get all three at once?
Solar + battery together saves on install costs. EV charger can come later — but a smart charger from day one captures solar surplus best.
What payback should I expect?
8–12 years for the combined system, faster on Octopus Flux due to higher export rates.
