A south-west roof on a steep plot, now covering most of a family of five's yearly use.
Location
Example Valley
System size
9.6 kWp
Panels
24 tier one panels
Battery
10 kWh LFP
Yearly output
10,900 kWh
The brief
A family of five with a heat pump and two home offices wanted lower bills and power that keeps running in short outages. The roof faces south-west and sits on a steep slope, so access needed careful planning.
What we installed
Twenty-four tier one panels in two strings, a hybrid inverter in the garage and a 10 kWh lithium iron phosphate battery wired to a backup circuit for the fridge, router and heating controls.
- Scaffold and install completed in two days
- Backup circuit switches over in under a second
- Monitoring app set up with the family on handover day
The result
In the first twelve months the system produced just under 10,900 kWh. The battery shifts evening use onto daytime sun, and grid imports dropped by around 70 percent.
Yearly savings
About 1,850 per year
Estimated from the first twelve months of monitoring data at current tariffs. Your own figures depend on roof, usage and tariff.
