FAQs
How much electricity can a typical residential solar PV system in Bristol generate?
Bristol receives on average 950–1,050 kWh of solar irradiation per installed kWp each year. A common 4 kWp rooftop array therefore produces roughly 3,800–4,200 kWh annually—about 60–70 % of an average household’s electricity demand. Generation peaks between March and September but the system will still produce energy, albeit less, during winter months.
What government incentives or financial support are available for solar installations in Bristol?
Under the Smart Export Guarantee (SEG) you are paid for every kWh of surplus electricity exported to the grid; rates currently range from 4–15 p/kWh depending on the energy supplier. Homeowners can also apply for 0 % VAT on domestic solar PV and battery storage until March 2027, reducing upfront costs by 20 %. In some Bristol postcodes, the council’s City Leap programme periodically offers group-buy or low-interest loan schemes—ask us for the latest availability.
Do I need planning permission to install solar panels on my property?
In most cases, roof-mounted solar PV is classed as ‘permitted development’ in England, so no formal planning application is required. The main exceptions are: (1) listed buildings; (2) properties in conservation areas where the array would face a highway; or (3) systems that protrude more than 200 mm from the roof surface. If any of these apply, we will handle the planning submission on your behalf.
How long does the installation process take from survey to commissioning?
After your free site survey and acceptance of our quotation, we book the installation at a time that suits you. A typical domestic job breaks down as follows: • 1 day for scaffold erection, • 1–2 days for panel and mounting installation, • half a day for inverter, cabling and consumer-unit integration, and • same-day electrical testing, DNO notification, and hand-over. Altogether, most homes are fully commissioned within 2–3 working days on site, plus 2–4 weeks lead time for scaffolding and equipment delivery.
What maintenance do solar panels require and how long do they last?
Solar PV has no moving parts, so routine maintenance is minimal. Bristol’s regular rainfall usually keeps panels clean; if your roof accumulates heavy dirt or bird droppings we recommend a professional clean every 3–5 years. Inverters typically last 10–15 years; panels are warranted for 25 years and often exceed 30 years of useful service. We offer annual health-check packages that include visual inspection, performance benchmarking, and remote monitoring reports.
Will solar panels work effectively in Bristol’s often cloudy weather?
Yes. Modern photovoltaic cells convert diffused as well as direct sunlight, so they still generate electricity on overcast days—just at a lower rate. Because cooler temperatures improve panel efficiency, Bristol’s mild climate can actually boost performance compared with hotter regions. Our designs use high-efficiency monocrystalline modules that deliver solid output even at low light levels, ensuring a reliable year-round contribution to your energy needs.
