Premium Solar Panel Installation
Bespoke solar PV systems designed for your home, your roof, and your energy goals.
Solar panel installation is the foundation of everything we do at Lumos Energy. Every system we design starts with understanding your property, your energy usage, and what you want to achieve — whether that's slashing your electricity bills, achieving energy independence, or reducing your carbon footprint.
We don't sell off-the-shelf packages. Every installation is bespoke: designed around your roof orientation, pitch, available space, shading profile, and household consumption patterns. This approach means you get a system that actually performs to its projected output — not one that looks good on paper but underdelivers in practice.
Wiltshire and the South West receive approximately 1,620 hours of sunshine annually, with solar irradiance of 980 kWh/kWp. A typical 4kW residential system in our region generates around 3,920 kWh per year — enough to power the average home's electricity needs for 9-10 months.
As MCS Certified and NICEIC Approved installers, every system we install qualifies for the Smart Export Guarantee (SEG), currently paying approximately 10.8p per kWh for surplus energy exported to the grid. Combined with the current 0% VAT rate on domestic solar installations (available until March 2027), the financial case for solar has never been stronger.

Solar Panel FAQs
Most Wiltshire homes install between 10-16 panels (4-6.5kW). The exact number depends on your roof space, electricity usage, and budget. A 4kW system (10 panels) suits a 2-3 bedroom home; 5-6kW (13-16 panels) suits larger properties with higher consumption.
Yes. Solar panels generate electricity from daylight, not direct sunshine. They produce less on overcast days, but Wiltshire receives 1,620 hours of sunshine annually and solar irradiance of 980 kWh/kWp — strong enough for excellent solar performance year-round.
South-facing roofs generate the most energy, but east and west-facing roofs still produce 80-85% of optimal output. East-west splits can actually be more useful if you are home mornings and evenings. North-facing roofs are generally not suitable.
Modern solar panels have a typical lifespan of 25-30 years, with manufacturer performance warranties guaranteeing at least 80-85% output at year 25. The inverter may need replacing once during the panel lifetime (typically after 10-15 years).
