Solar & battery installers in Bristol
Most people buy solar panels and hope for the best. There's a smarter sequence, and it starts before you've fitted a single panel.
A typical UK home uses 8 to 12 kWh of electricity a day. Match your battery to that, fill it overnight when power is cheapest, and run the evening peak off it. That works in January just as well as July.
Scaffolding, labour, the inverter and the paperwork cost the same whether you fit 6 panels or 14. Going from 6 panels to 14 costs about 25% more and generates 133% more electricity, so half-covering a roof is the most expensive way to buy solar.
SEG rates in 2026 range from 4p to 20p per kWh depending on supplier and tariff. OVO's Install Exclusive sits at the top of that range when OVO fits solar and battery and supplies your electricity.1 At 20p, surplus generation stops being waste and starts being income.
We size all three moves around your actual usage, on the call.
Solar panels run on daylight, not heat. The UK averages 998 kWh per kWp per year, about 2.7 peak sun hours a day. Even Aberdeen beats a lot of Germany, which has more installed solar than anywhere in Europe.
Also covered: solar installers in Thames West, South West Scotland and the Thames Valley.
Figures assume a south-facing roof at optimal pitch with no significant shading. Your free design accounts for your actual orientation, pitch and shading. Export income assumes roughly 55% of generation is exported on a typical system with battery.
Regional generation figures from the European Commission PVGIS database (v5.2), long-term average by region, modelled at a 35 degree pitch facing south.
Takes about two minutes. Your local OVO expert confirms your free video design within one working day.
A typical installation runs from about £6,411 for a 6-panel (2.7 kWp) system to £7,990 for a 14-panel (6.3 kWp) system. Adding battery storage costs around £2,444 more.
The important number is cost per kWp, and it drops sharply as the system grows, from £2,374 per kWp on a small system to £1,268 per kWp on a large one. That's because scaffolding, labour, the inverter and certification cost the same regardless of how many panels you fit.
Indicatively,5 battery storage adds around £2,444 for roughly 5.2 kWh of usable capacity, about £470 per usable kWh, fitted and commissioned. That price is flat across all our system sizes.
It also lifts your export rate from 15p to 20p per kWh, so on a system exporting 3,500 kWh a year the tariff uplift alone is worth about £175 a year before you count any storage savings.
About 998 kWh per kWp installed per year as a UK average, roughly 2.7 peak sun hours a day. A 6.3 kWp system (14 panels) generates around 6,300 kWh a year.
It varies by region: Devon and Cornwall reach about 1,060 kWh per kWp, London and the Thames Valley about 1,000, Yorkshire about 910, and north east Scotland about 850. Even at the lowest end, a full roof generates more than most households use.
Indicatively, 7 to 14 years, depending on size, based on our regional partner pricing.5 A 14-panel system with battery pays back in around 7 years; 10 panels in around 9; 6 panels in around 14.
Bigger systems pay back faster, because the fixed costs are spread across more generating capacity. Panels are warranted to keep performing for 25 years, so a 7-year payback means roughly 18 years of pure return.
One of 16 regional partner businesses, selected from around 200 installers assessed and interviewed between 2025 and 2026. Each holds the exclusive OVO partnership for its region.
They're established local companies, not subcontractors picked off a list, working to OVO's standards and backed by a 10-year workmanship warranty. OVO Solar & Battery connects you with the partner for your area; the partner carries out the installation.
OVO's SEG Install Exclusive tariff pays 20p per kWh when OVO installs both your solar panels and your battery, or 15p per kWh for solar only.
For context, OVO's standard SEG rate, open to customers of any supplier, is 4p per kWh, and SEG rates across the market in 2026 range from 4p to 20p per kWh depending on supplier and tariff. On a system exporting 3,500 kWh a year, that's roughly £700 versus £140.
Get them together if you can, but if you're sequencing, think about the battery first. A battery sized to your daily usage saves money from day one by shifting your consumption to cheap off-peak hours. It works in December as well as June, with no dependence on sunshine.
Then fill the roof with as much solar as it will take. The marginal cost of each extra panel is low, and with a 20p export rate you're paid properly for everything you don't use.
Match it to your daily electricity use, not your roof. Most UK homes use 8 to 12 kWh a day, and a large share of that lands in the evening peak, which is exactly what a 5.2 kWh usable battery is sized to cover.
Oversizing wastes money: a battery you only half-cycle earns half as much. On your design call we'll look at your actual consumption before recommending anything.
East and west facing roofs perform well, typically 85 to 90% of a south facing roof's output, and an east/west split array spreads generation across the morning and evening rather than peaking at noon. North facing roofs generate less, and whether they are worth panelling depends on the roof and how you use energy, which is exactly what your free design call assesses. Shading is often more of a problem than orientation, but optimisers or micro-inverters usually solve it. We assess both from aerial imagery and tell you straight if it isn't worth doing.
You need to own the property, so we can only install for homeowners. We install on detached, semi-detached and terraced houses.
We're not currently able to install on flats and apartments, because of shared roof ownership and communal wiring. If you own a leasehold house with a roof of your own, get in touch and we'll check.
Domestic solar panels and battery storage installed in residential property in Great Britain currently attract 0% VAT. All prices shown here are what you'd pay.
The relief is set by HMRC and is currently due to run until 31 March 2027, after which the rate is scheduled to return to 5%.
Most installations are completed in one to two days. Solar-only jobs are often a single day; adding a battery usually means a second.
Scaffolding typically goes up the day before and comes down a day or two after. Your partner will confirm the schedule before booking anything in.
