FAQs
Is Bristol sunny enough for solar panels to be worthwhile?
Absolutely. Bristol receives around 1,600–1,700 hours of sunlight per year—only about 10 % less than the UK’s sunniest regions. Modern photovoltaic (PV) modules work efficiently in diffused light as well as direct sunshine, so even on cloudy West-Country days your array will keep generating electricity. A well-sited 4 kW home system in Bristol typically produces 3,800–4,200 kWh annually, covering 60–80 % of an average household’s electricity demand and cutting carbon emissions by roughly 1 tonne per year.
How much will a typical domestic solar installation cost and what incentives are available?
A standard 4 kW roof-mounted PV system currently costs £5,500–£7,000 fully installed, including MCS certification and DNO notification. Larger 6–8 kW systems range from £8,000–£11,000. Key financial benefits include: • Zero-rate VAT on domestic solar until 2027, saving 20 % instantly. • The Smart Export Guarantee (SEG), which pays 4–15 p/kWh for surplus energy exported to the grid. • Local grants and low-interest ‘Green Homes’ loans available through Bristol City Council and WECA (checked case-by-case). With self-consumption plus SEG income, payback is typically 6–9 years, after which the electricity you generate is effectively free for the remaining 15–20 years of system life.
Will I need planning permission to install solar panels in Bristol?
In most situations solar panels are considered ‘Permitted Development’, so no formal planning application is needed. The main exceptions are: 1. Listed buildings or properties in Conservation Areas where panels face a highway. 2. Flat-roof or ground-mounted arrays exceeding 4 m in height. 3. Installations that protrude more than 20 cm from the roof plane. We carry out a free site survey to confirm compliance. If permission is required, we can prepare drawings, heritage statements and submit the application on your behalf.
How do solar panels integrate with the electrical grid, and can I add battery storage?
Your PV array feeds a smart inverter that synchronises with the grid frequency and connects to your consumer unit via a dedicated breaker. Excess generation flows through your smart meter and is recorded for SEG payments. Batteries are optional but increasingly popular; a 5–10 kWh lithium-ion pack lets you store daytime surplus and use it in the evening, boosting self-consumption from ~40 % to 70-85 %. We supply hybrid inverters that make it easy to add storage now or later, and we’ll handle the Distribution Network Operator (DNO) G98/G99 notifications required for systems over 3.68 kW export.
What maintenance do solar panels require and how long do they last?
PV systems are largely maintenance-free because they have no moving parts. Bristol’s regular rainfall helps keep panels clean, but we recommend a professional visual inspection and performance check every 2–3 years, plus cleaning if your output drops noticeably (e.g., in areas with heavy bird activity or tree pollen). Panels carry 25-year output warranties (80–85 % of initial power) and often continue producing well beyond 30 years. Inverters typically last 10–15 years; we offer extended warranty options and remote monitoring so you can see real-time generation on your phone.
How quickly can you install the system and what certifications do you hold?
From signed order to switch-on, a domestic installation usually takes 3–5 weeks, depending on DNO approval. The physical fit itself is just 1–2 days for most homes. Our team is MCS-accredited, NICEIC Approved, and members of the Renewable Energy Consumer Code (RECC). We’re also TrustMark registered and fully insured. These certifications mean your installation meets rigorous safety, performance, and consumer-protection standards, and they’re mandatory for you to claim SEG payments or any local grants.
