Positive news from EvoEnergy includes their new guarantee policy: they will now give a five year guarantee for their estimate of each PV system’s energy generation level. As solar PV is a relatively new technology in the UK, this offers prospective buyers reassurance that they are making a sound investment.
Installing a solar PV system on one of the first Code 5 homes for sale to the public was also a milestone. Code 5 homes are 100% energy efficient buildings and all homes built from 2016 will have to meet this standard, generating their own electricity and heating. More on these standards 1-6 (zero carbon) on the Energy Savings trust website and – in more detail – a government portal.
Scotland’s Energy Saving Trust reports on a 100% affordable Code 5 housing scheme (above): “The new homes are in keeping with the surrounding area and mirror the predominantly red-brick Victorian architecture of the village. However despite their conventional appearance, the properties boast many green features such as photovoltaic panels, biomass wood-chip boilers and triple-glazed windows. They were built using innovative structural insulated panels which contribute to a reduction in their energy consumption. Mid Street’s tenants will enjoy cheaper fuel bills and a more sustainable way of life”.
EvoEnergy has just completed a huge 249kWp installation at the Portsmouth’s Gunwharf Quays shopping centre right on the harbour front. Each year this system will generate 200,807kWhs of usable electricity, saving over 106,200kg of carbon dioxide emissions, reducing the shopping centre’s electricity bill and helping the environment by burning fewer fossil fuels. The roofing structure at Gunwharf Quays couldn’t cope with any significant extra load, so the team designed an innovative light-weight mechanical fixing solution that enabled the roof to remain intact. The owners, Land Securities, wanted to ensure that the shopping centre’s business was unaffected. Crane lifts had to be operated out of hours, so EvoEnergy organised any access, lifting and other ground level activity to be carried out very early on Sunday mornings to ensure that no-one was disturbed. Working during the wettest summer ever recorded made the on-site conditions less than ideal and the teams faced high winds and downpours to get the installation completed on time.
Walking around my neighbourhood yesterday evening I saw sunshine still pouring on to roofs and deeply regretted that this was not generating electricity and making the country more energy-independent and economically efficient – see the Green New Deal website.
