What Dorchester Homeowners Say About Our Solar Installation Specialists
10 x 440W LONGi Hi-MO panels installed on our Dorchester south-east 35-degree slope. EV-ready setup with PV diverter to the immersion. System size 35kWp. Total £14400 fitted. Building Notification submitted by the contractor.
Three MCS-certified solar firms quoted via BestBuilders for our Dorchester 1970s detached. Picked the mid-priced quote at £7800 - 12 panels and a 5kWh battery. New panels matched in spec to two existing panels we already had - all on the same string. EPC went up one band thanks to the new generation capacity.
Two summers on, the EV charger paired with the panels is genuinely free fuel. Installer near Dorchester recommended panel optimisers because of the gable shading - good call. EPC went up to a B from a D thanks to the new generation capacity.
