A family home in Slough wanting solar, battery storage and home EV charging delivered as one integrated package.

With an electric vehicle in the household, the priority was self-consumption — using as much homegrown power as possible rather than exporting it cheaply. The Sigenergy platform let the panels, battery and EV charger work as a single managed system.

The technical scope included:

• 20 × Aiko 510W solar panels (10.2 kWp total capacity)
• SigenStor EC 10.0SP hybrid inverter
• 2 × SigenStor BAT 10.0 (18 kWh usable storage)
• Sigen HomeMax gateway + Sigenergy 7kW AC EV charger

Solar4Good delivered the full Sigenergy ecosystem as a single, managed installation.

Key aspects included:

• Integrated Platform – Panels, battery, gateway and EV charger run as one Sigenergy system.
• Self-Consumption First – Configured to charge the home battery and the car before exporting.
• High-Efficiency Panels – Premium Aiko 510W modules for maximum output per panel.
• Safety & Compliance – Installed fully in line with UK building and electrical standards.

Daytime generation now charges both the home battery and the car, lifting self-consumption to around 68% — before counting the separate saving on petrol the EV charging replaces.

Environmental impact:

• Average CO₂ savings: 2,040 kg/year
• Equivalent to planting 2,100 trees over the system’s lifetime
• Lifetime CO₂ offset: ~51,000 kg

Financial savings:

• Lifetime savings: ~£46,000
• Average savings: ~£1,850 per year
• ROI / Payback period: 8–9 years

Client benefits:

• Solar, storage and EV charging in one system
• Additional fuel savings from charging on solar
• Significant contribution towards Net Zero
• Single-app control of the whole setup
