Brightening up Bridgend homes!
See how we helped this homeowner in Wales slash their energy bills with solar and battery!
Project Overview
The homeowner was looking for a clever way to tackle rising energy costs. Our customised solar and battery system was built to optimise self-use, storing as much clean, affordable electricity in the home as possible.
System Cost: £16,998.42 (inc. VAT)
System Size: 12.6kW system (28 DMEGC Solar Panels)
Battery Storage: Fox ESS 20.7kWh battery storage system
Customer Goal: Cut rising energy bills

Performance & Savings
Estimated Annual Generation: 8,664 kWh
Annual Savings: £1,073 (plus £651 export income)
Electricity Bills Reduced: From £1,315 → £242 per year
Payback Period: 11 years
The system now covers 81% of the home’s annual electricity demand, significantly reducing reliance on the grid and boosting energy independence.
Battery Storage Benefits
The 20.7 kWh battery transforms how the system works:
-
Solar used directly (without battery): 38%
-
Solar used with battery: 81%
-
On-site storage used: 3,726 kWh annually
-
Grid reliance: cut to just 19%
Result: Most of the solar electricity generated is stored and used in the home, maximising clean, low-cost power instead of exporting it back to the grid.
Grid Export & Energy Use
Export to Grid: 4,787 kWh per year
Import from Grid: 874 kWh per year
Daily Average Generation: 23.7 kWh
Daily Household Use Covered by Solar + Battery: 12.9 kWh
Overall Energy Independence: 81%
Environmental Impact
This installation makes a measurable difference:
🌱 Annual CO₂ reduction: 1,794 kg
🚗 Equal to 6,407 miles driven in a diesel car
🌳 Equivalent to the carbon absorption of 82 trees per year
Summary
This 12.6 kW solar array with 20.7 kWh battery:
Cuts electricity bills by 82%
Delivers ~£1,724 in annual savings (including export income)
Avoids 1,794 kg of CO₂ each year
Creates long-term energy security and independence
Result: More clean energy stays in the home, the grid is used less, and the environmental impact is substantial.
