Solar energy in Colchester: local context
The East of England benefits from lower rainfall and flatter terrain compared to western regions, resulting in less shading and more consistent solar performance. The region's mix of market towns and new-build developments offers good installation opportunities.
Colchester homeowners benefit from 0% VAT on residential solar installations (until at least March 2027) and can earn income through the Smart Export Guarantee by selling surplus electricity back to the grid.
