21-Panel Solar Installation in Hailsham

21 panels · 9.9 kWp · 10.0 kWh battery

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 generates 10,482 kWh each year, offsetting 218% of the home's energy consumption. This setup provides estimated annual savings of £2,166.

Installer’s notes

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.
