21-Panel Solar Installation in Ninfield
21 panels · 9.7 kWp · 20.0 kWh battery
About this installation
We completed a 21-panel solar installation for a homeowner in Ninfield in May 2026. This system features 21 JA Solar JAM54D41-460/LR panels, delivering a total size of 9.66 kWp. An Anker SOLIX X1-H6K-S inverter manages the power, paired with an Anker SOLIX X1-B5-H battery storage system with 20 kWh capacity.
The Ninfield system typically generates 10,826 kWh annually. That is around 93% of the home's annual electricity use. Based on current figures, this system provides estimated annual savings of £3,133.
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, 9.66 kWp (the size of the solar array), with 20 kWh of Anker storage, the largest battery on anything we have published. The design showed it making slightly less than the household uses in a year. So there is enough demand here to empty a battery that size. The customer counted five vans on the drive on the first day and called the team "smooth, seamless, considerate". He had notifications about his charge levels afterwards, and Lee changed the settings for him while he was on holiday.
What the customer said
From their public Google review of this installation.
“Lee was knowledgeable, not too techy and answered all our questions honestly. The team were large - I had 5 vans on the drive the first day putting up 21 panels with their batteries. Smooth, seamless, considerate, jolly, sincere are the words I'd use to describe them. Lee is extremely responsive to messages- we had some notifications about the charge levels and he modified the settings whilst on hols!”
