Dulas claims to have delivered the largest solar PV array in the UK for the National Trust at its Grade I listed Llanerchaeron property in Wales.
At just under 40kWp (37.5kWp) and combined with the existing 7.5kWp solar PV array the installation should generate up to half of the electricity that the house requires. Having provided a full planning consultancy service for multiple solar PV sites across the National Trust portfolio in Wales, Dulas advised a free standing ground mount ballasted array would provide the optimum solution to be delivered within the tight timescales.

Dulas' Mike Clay said: 'By taking forward thinking steps and engaging with a highly experienced company the Trust has been able to best utilise the space available to gain maximum benefit from the feed in tariff. By prioritising the installation Dulas was able to commission the project in time to take advantage of the highest feed in tariff rates providing the best possible financial rate of returns for the Trust.'

The Trust has made a commitment to reduce their reliance on fossil fuels by 50 per cent within the next eight years. It aims to cut their carbon emissions from energy use for heat and electricity by 45 per cent, beating the Government's target of a 34 per cent reduction in CO2 by 2020.

The Trust has also made a pledge to take care of the environment by reducing energy and water use and substantially cutting dependence on energy sources outside its estate and by developing its own energy sources. Key in achieving this has been the use of biomass technology which Dulas has taken the lead in delivering.

Dulas has in the last month delivered biomass wood fuel heating systems for the National Trust at both Stackpole and South Pilton Green. Stackpole is now home to a 350kW boiler which replaces 17 ageing LPG boilers while South Pilton Green operates a 35kW boiler which is linked to a small district heating scheme. This system is containerised to provide an innovative solution to space and access issues. The Trust had limited locations to house the boiler so by providing a 'boxed' solution Dulas was able to work around this issue.

Keith Jones, Environmental Practices Advisor for the National Trust, said: '[Dulas] have worked with us to deliver the bespoke solutions and were impressed by their ability to install our first large scale solar PV system within the very tight Feed-in Tariff deadline.'
