The Challenge
Looking for a way to reduce their reliance on the grid amidst rising energy costs while maintaining the visual integrity of their countryside home. This household’s key goals were:
- Full home backup during power outages
- Reduced carbon footprint
- Future-proofing their property for EV charging and renewable energy storage
They needed a clean, high-performance solution that wouldn’t compromise the character of their rural property.
The Solution
Bright Spark Energy designed and installed a tailored 8.1 kWp solar PV system integrated with Tesla Powerwall 3 battery storage. The all-black solar panels were chosen to blend seamlessly with the home’s exterior, providing both performance and aesthetics.


System Components:
- Fully MCS certified with DNO notification
- 18 x JA Solar 450W High-Efficiency Panels
- Tesla Powerwall 3 hybrid inverter
- Tesla Powerwall 3 13.5 kWh battery
- Tesla Backup Gateway 2 for full-home backup
- Mobile app for online monitoring
The solar array was strategically positioned to maximise South-East and South-West sun exposure, ensuring optimal energy generation from early morning through late afternoon.
The Results
This home now generates over 7,000 kWh of clean energy per year—enough to cover their daily usage, store excess energy for evening use, and export the surplus through the Smart Export Guarantee (SEG).
Key Benefits:
- Estimated payback period: under 8 years
- Annual savings: £2,064
- Carbon offset: ~2,000 kg/year
- Positive impact on EPC and property value
- Seamless integration with EV charging and battery storage
- Resilient energy supply during power outages
