Solar Panel & Battery Installation
Solar panel and battery installation across the UK as one package — Tier-1 panels, a Tesla Powerwall 3 or EcoFlow battery, and a hybrid inverter sized to work together from day one. Self-consumption 80%+, 0% VAT until 2027. Free survey: 0800 099 6606.
Solar and battery, installed together
Installing solar panels and a battery together is the lowest cost-per-kWh route to energy independence. One install, one set of scaffolding, one hybrid inverter — and self-consumption of 80%+ from day one versus ~30% for solar alone. A typical combined system pays back in 10–12 years and protects you from rising grid prices.
Why install solar and battery at the same time
Solar panels alone only let you use about 30% of what you generate — the rest is exported, often for a fraction of what you pay to buy it back in the evening. Adding a battery stores your daytime generation for use at night, lifting self-consumption past 80% and turning a smart export tariff into real savings.
Doing both at once is materially cheaper than retrofitting later: you share one set of scaffolding, one survey, and one MCS certificate, and — crucially — the hybrid inverter is sized for the battery from the start, so you never pay to swap the inverter out down the line. It also means a single DNO application and a single, tidy commissioning visit.

From survey to switch-on
Free survey
A solar PV engineer assesses your roof, shading, consumption and tariff, then sizes panels and battery together so the hybrid inverter is right first time.
System design
We design the combined system in PV*SOL, confirm 0% VAT eligibility, submit DNO (G98/G99) and SEG paperwork, and give you a fixed-price quote.
One-day install
One set of scaffolding, one team, one MCS certificate. Panels, hybrid inverter and battery are commissioned together — no return visit, no retrofit labour later.
Monitoring & handover
You get the app on day one with free lifetime monitoring and automatic fault alerts, plus full manufacturer and workmanship warranties.
Unlock the best export tariffs
A battery is what makes smart tariffs pay. On Octopus Flux you charge cheaply overnight, run the house off stored solar through the day, and export at the 24p peak rate in the evening — a swing worth £600–£900/year over a basic export tariff. Solar alone can't time-shift like this; the battery is the difference between exporting at 15p and exporting at 24p.
