21-Panel Solar Installation in Polegate

21 panels · 9.9 kWp · 9.3 kWh battery

In July 2026, Eastbourne Energy successfully completed a comprehensive solar and battery installation for a homeowner in Polegate. This impressive system integrates 21 high-performance Jinko Solar JKM470N-60HL4 panels, forming a substantial 9.87 kWp array. The setup includes a reliable Fox ESS KH7 inverter paired with a Fox ESS ECS4800-H2 battery, which offers a significant storage capacity of 9.32 kWh. Operational since its completion, this Polegate system delivers substantial energy independence and financial benefits to the homeowners. It typically generates 8,679 kWh annually, effectively offsetting around 46% of their energy consumption. This efficient solution provides estimated annual savings of £1,996, demonstrating the tangible rewards of investing in sustainable home energy.

Installer’s notes

21 panels, 9.87 kWp (the size of the array), with a Fox ESS ECS4800-H2 battery of 9.32 kWh. It runs on a Fox ESS KH7 inverter. Even with an array this size, the design covered under half of what the household uses. This home gets through a great deal of electricity. A system like this brings a big bill down rather than removing it, and we say so at quote stage.
