A high-consumption detached family home in Dovercourt, near the Essex coast, looking to bring down rising electricity bills and add meaningful battery storage.

The roof had the space and orientation to carry a substantial array, and the household’s usage pattern justified a large battery bank to shift daytime generation into the evening peak.

The technical scope included:

• 26 × Jinko 440W solar panels (11.44 kWp total capacity)
• FoxESS KH10 hybrid inverter
• 2 × FoxESS EP11 batteries (20.7 kWh usable storage)
• Bird mesh fitted to all pitched-roof panels

Solar4Good handled everything from the first site survey and design through to installation and commissioning.

Key aspects included:

• Optimised System Layout – Panels arranged to make the most of the available roof while accounting for shading.
• High-Efficiency Equipment – Tier 1 Jinko panels paired with a FoxESS hybrid inverter for reliable long-term performance.
• Future-Proofing – Sized and wired so an EV charger can be added with minimal extra work.
• Safety & Compliance – Installed fully in line with UK building and electrical standards as an MCS-certified installer.

Around two-thirds of the home’s electricity now comes from its own roof, with surplus stored rather than exported at a low rate — a strong all-round performer for a high-usage household.

Environmental impact:

• Average CO₂ savings: 2,300 kg/year
• Equivalent to planting 2,400 trees over the system’s lifetime
• Lifetime CO₂ offset: ~57,000 kg

Financial savings:

• Lifetime savings: ~£50,000
• Average savings: ~£2,000 per year
• ROI / Payback period: 7–8 years

Client benefits:

• Stabilised energy costs against UK tariff volatility
• Significant contribution towards Net Zero
• Increased property value and resilience
• Whole-home storage for evening peak demand
