FAQs
Does Bristol receive enough sunlight for solar panels to be effective?
Yes. While Bristol’s weather is often overcast, modern photovoltaic (PV) panels generate electricity from daylight rather than direct sunshine. The city averages about 1,400–1,500 kWh of solar-irradiation per square metre each year—comparable to much of southern Germany, where solar is widespread. A well-sited 4 kWp domestic array in Bristol typically generates 3,600–4,000 kWh annually, covering 60–100 % of an average home’s electricity demand.
What local incentives or financial support are available for installing solar in Bristol?
Homeowners and businesses can benefit from several schemes: • Zero-VAT on domestic solar installations (until March 2027), cutting capital costs by 20 %. • Smart Export Guarantee (SEG): Bristol suppliers such as EDF, Octopus, and Ecotricity pay 5–15 p/kWh for surplus electricity exported to the grid. • Bristol City Council’s ‘City Leap’ programme offers occasional grants/low-interest loans for energy upgrades—check availability before ordering. • ECO4 and ECO+ funding may help eligible low-income households combine solar with insulation measures. • Businesses can claim a 100 % first-year allowance under the UK’s Full Expensing scheme, writing off the system cost against corporation tax.
How long does a typical residential solar installation take from survey to switch-on?
1. Initial survey & quotation: 1–2 weeks after enquiry. 2. Design, component ordering, and DNO (Western Power) application: 2–4 weeks. 3. Scaffolding and panel mounting: 1–2 days on site. 4. Electrical wiring, inverter, and commissioning: 1 day. 5. DNO approval & Smart Export Guarantee registration: 1–2 weeks post-install. Overall, most Bristol households are generating solar electricity within 6–8 weeks of signing the contract, with actual on-roof work completed in 2–3 days.
Do I need planning permission for solar panels in Bristol?
For the majority of pitched-roof residential installations the answer is no: solar panels are ‘Permitted Development’ under UK planning law. You must: • Ensure the array does not project more than 200 mm from the roof surface. • Install below the ridgeline and match the roof’s angle. • Minimise visual impact on the street. Exceptions where planning consent is required include listed buildings, properties in designated conservation areas, and ground-mounted arrays over 9 m². Our team handles all paperwork if an application is necessary.
What maintenance is required and how long do solar panels last?
Solar PV is low-maintenance: • Lifespan: Panels are warranted for 25 years to at least 80 % of their original output; many keep producing for 30+ years. • Cleaning: Bristol’s rainfall usually keeps panels clear. An annual visual check or light clean after pollen season maximises yield. • Inverter: Expect replacement after 10–15 years; warranties up to 12 years are available. • Monitoring: Our installations include app-based monitoring so you can spot performance drops quickly. We offer annual service plans, but most owners spend little to nothing on upkeep.
Will my solar panels keep working during a power cut, and can I add batteries later?
For safety, grid-tied inverters shut down during an outage to protect line workers, so standard systems do not power your home in a blackout. Options: • Install a hybrid inverter plus battery from the outset to provide backup power to critical circuits. • Retrofit: We can add battery storage later; most modern inverters are battery-ready, or we can fit an AC-coupled unit. • Duration: A 5 kWh battery can run essential loads—lights, Wi-Fi, fridge—for several hours. Adding storage also increases self-consumption of solar energy from about 30 % to 60–80 %, shortening the payback period by 1–3 years.
