Head Office Building Richmond | Richmond, Surrey TW9

Solar PV

Annual Benefit: £3,065
CO2 saved pa: 4.9 t


No 3 Water Lane, Richmond-upon-Thames is the Head Office for independent oil & gas engineering & management specialists Penspen Ltd. As part of on-going maintenance work the building’s flat and un-shaded roof was due to be replaced. This provided the perfect opportunity to design & install a renewable energy system.

The objective was to optimise power generation for use in the offices and thereby maximise the return on investment from effective use of the Feed-in-Tariff.

We designed and installed a solar photovoltaic system using a multi-input inverter along with web based monitoring.

With a high 24/7 continuous base load virtually all the electricity generated will be used on the premises thereby enhancing the cost-saving and return-on-investment forecast. The system generates an annual income guaranteed for 25 years and saves close to 5t CO2 pa.

Report - 3 years on

We installed their Solar PV System back in Feb 2012 and it has now been fully operational for 3 years. The initial forecast payback period was 7.9 yrs however, system performance is actually exceeding expectations. 

Chris Williams, Regional Director Europe and Africa commented

“We’ve had our system just over three years, it has worked without problem and has enabled us to use less electricity from our supplier and helps our carbon footprint a great deal. It’s earned us a very good rate of return so it should be paid off well within 5 years, and it’s nice to know our roof is earning us some money!”
