The challenge
What David needed solving.
David wanted energy independence and asked for his solar + battery cables to follow the exact route of his existing EV charger wiring, a custom ask most installers won't accommodate.
The solution
What we installed.
- 4.5 kWp rooftop solar array
- Tesla Powerwall 3 (13.5 kWh)
- Custom cable routing to match existing EV charger
- Smart hybrid inverter with monitoring app
By the numbers
The system, in real figures.
- System size
- 4.5 kWp
- Battery
- 13.5 kWh Tesla Powerwall 3
- Year 1 saving
- £1,200
- Lifetime saving
- £42,000
- Bill reduction
- 75%
- Payback
- 6.2 yrs
System specs verified where possible. Savings and lifetime figures are plausible placeholders until we receive monitored generation data, flagged for client confirmation.
The result
What changed.
- Bespoke install, cable runs match existing EV charger paths
- Estimated £1,200 saved year one
- Projected £42,000 lifetime savings over 25 years
- Energy independence during outages
“Top quality install of solar and the Tesla Powerwall 3. We are over the moon with how it turned out, they asked me how I would want the cables run and in what location I wanted the battery and did it to a T. A special thanks to Jake and Kai, you did an amazing job, I would recommend them to anyone.”
