21-Panel Solar Installation in Hailsham
21 panels · 9.9 kWp · 10.0 kWh battery
About this installation
In July 2026, we completed a 21-panel solar installation for a homeowner in Hailsham. This system delivers 9.87 kWp. It uses 21 Jinko Solar JKM470N-60HL4 panels and an Anker SOLIX X1-H6K-S inverter.
The installation includes a 10 kWh Anker SOLIX X1-B5-H battery. The system is modelled to generate around 10,482 kWh a year, about 218% of the home's annual electricity use. This setup provides estimated annual savings of £2,166.
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 10 kWh Anker battery. The design showed it making more than twice what the household uses. So most of the value is in what gets stored for the evening and what gets exported. The battery is the same 10 kWh unit we fitted on the 17 panel job nearby. That is our most common size across the published work.
