21-Panel Solar Installation in Polegate
21 panels · 9.9 kWp · 9.3 kWh battery
About this installation
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 is modelled to generate around 8,679 kWh a year, about 46% of the home's annual electricity use. This efficient solution provides estimated annual savings of £1,996, demonstrating the tangible rewards of investing in sustainable home energy.
Generation and consumption figures are design-stage estimates: the system’s modelled annual output compared with this household’s annual electricity use at the time of the quote. They are an annual energy comparison, not the share of the home’s demand met directly, and not measured results.
Installer’s notes
What the customer asked for, why the system was designed this way, and what the job involved.
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.
