Projects

The owners of this beautiful garden decided to reduce their carbon footprint – and have been able to take advantage of the new feed-in tariff rates at the same time. The panels used are powerful Romag 230W (made in the UK) combined with a Fronius IG30 inverter. This creates a peak output 0f 3.22kW, that will produce about 2800kWh a year and an annual income of around £1200. With carbon saving of over 1.2 tonnes a year and electricity bills slashed this was a sound investment.

For this 3.6kW system, we used 18 Romag 200W panels with an SMA Sunny Boy 3000 transformerless inverter.

A year after installation, this system had generated 3792kWh (compared to our SAP estimate of 3092kWh). That represents not only an uplift of 22.6%, but a return on investment of 12.2% – excluding the savings in electricity bills.

In Bishopston, Bristol, this 2.5kW system consists of 12 Kyocera 210W panels with a Fronius IG20 inverter. The photo was taken as the scaffolding came down at sunset, hence the shadows. It is on track to produce well over 2000kWh a year.

This 1.6kW installation on a garage in Somerset consists of 12 Kyocera 135W panels with a Fronius IG15 inverter. The owners wanted to reduce their dependence on fossil fuels. They also run a smallholding, growing fruit and vegetables, and keeping pigs, chickens and sheep. Their dream is self-sufficiency, and this array should help them on their way.
