Two barn conversion family homes near Tamworth

The customer

This was an energy efficiency/cost-saving installation to feed two neighbouring, barn conversion family homes near Tamworth.

What was involved?

It included a design and installation that would give maximum panel output, and also battery back-up, to tackle the occasional local area power cut.

What we did

We designed and installed the largest possible PV system, sharing a south-facing garage roof, situated between the two buildings.

System one included –

• 22 x JA Solar 460W Mono MBB Percium Half-Cell Silver Frame MC4
• 1 x 8kw Solaredge 1ph Inverter HD-Wave. No display
• 22 x P505 Solaredge optimisers
• Solaredge Modbus meter
• 12.6kwh Solax HV storage with EPS mode

System two included –

• 14 x JA Solar 460W Mono MBB Percium Half-Cell Silver Frame MC4
• 1 x 6kw Solaredge 1ph Inverter HD-Wave. No display
• 14 x P505 Solaredge optimisers
• Solaredge Modbus meter
• 12.6kwh Solax HV storage with EPS mode

The difference made

Now fully installed, the two systems combined are offsetting 4.6t of CO2 emissions, per year and have a predicted output of 15 MWh output per year.

Our illustration shows the monitoring of the amount of power generated and the electricity used.

With everything up and running, taking the example of a single day in March (but not including power exported to the grid) the power that the two families used, cost just 46p

Please note, this is a good example of the potential savings. Not all days will be like this, some will be better and some not as good.
