Washington Residential Solar PV Installation

3.84kW Sanyo System with Fronius Inverter

Mr & Mrs Farthing approached Sustainable Energy Engineering after confirming their eligibility for solar PV funding. After reviewing several options, they selected us for the job thanks to our competitive quotation and track record of professional installations.

The system features 16 × 240W Sanyo HIT HD panels, paired with a Fronius IG 35 grid-tie inverter — both chosen for their strong efficiency and proven reliability. The panels were installed across the property’s roofline to ensure maximum solar capture and performance.

With an expected annual generation of 2,881 kWh, the system is projected to deliver annual returns of £1,391.00. This installation highlights how funded solar can offer excellent returns while reducing environmental impact for homeowners.
