What savings can I expect?

That depends on how much of your solar electricity you use at home, your import tariff and your export rate, so we model it for your household rather than quoting a town average. As a starting point, PVGIS estimates about 1,013kWh a year per kWp for a south-facing, 35-degree roof in High Wycombe, so ten AIKO 485W panels (4.85kWp) would be modelled at roughly 4,900kWh a year before any site shading. A battery lets you use more of that yourself. Smart Export Guarantee payments on the power you export require an MCS-certified installation, and our installations are MCS certified.
