6kW Solar, Battery & Zappi EV Charger in Chippenham
Chippenham, Wiltshire (SN14) — 5-bed detached
A large family home with two electric vehicles. The homeowners wanted a complete energy solution: solar generation, battery storage, and smart EV charging from surplus solar.
The Challenge
The natural slate roof required specialist mounting hooks. Two EVs meant significant charging demand — approximately 8,000 kWh per year combined.
Our Solution
A 6kW array using slate-specific hooks with careful handling to avoid cracking. Zappi EV charger configured for solar divert mode — prioritising free solar electricity before drawing from the grid. The 10kWh battery handles evening household loads.
The Result
The family now charges both EVs primarily from solar during spring through autumn, saving approximately £900/year on fuel alone. Combined with household savings, the total system saving exceeds £1,600 annually.
“Having both cars charge from the roof while we are at work is incredible. The Zappi app shows exactly how much free solar is going into the car. Our petrol costs have dropped to near zero.”
