Most homes require 9-18 solar panels depending on electricity usage, roof size, and orientation. A 2-3 bed home typically suits a 9-panel 3.6kW system, a 3-4 bed home works well with 12 panels (4.5kW), and larger 4+ bed properties benefit from an 18-panel system generating 6-7kW. D&R Energy designs every system individually based on a detailed property survey.

The South West of England receives the highest solar irradiance in the UK! Solar panels in Bristol and Somerset consistently generate 950-1,100 kWh per kWp annually — up to 15% more than the national average. Even on cloudy days, modern panels produce significant electricity from diffuse daylight.

We install premium Jinko Solar and Exiom panels, paired with Growatt and GivEnergy inverters. These are tier-1 manufacturers chosen for their proven reliability, efficiency, and performance in UK conditions. All our installations are MCS certified.

With current electricity prices and 0% VAT, most domestic solar PV systems in the Bristol area pay for themselves in 5-8 years. Adding battery storage and using a smart export tariff can reduce this to 4-6 years. After payback, your electricity is essentially free for the remaining 25+ year lifespan.
