Common Questions

Commercial Solar FAQs
for Colchester

How much does commercial solar cost in Colchester?+
Commercial solar pricing in Colchester is project-specific and depends on system size, roof type, mounting method, DNO requirements and electrical infrastructure. We provide a detailed quote following a free feasibility survey. Most commercial systems deliver a return on investment within six to ten years.
Do commercial solar systems require planning permission in Colchester?+
Most commercial roof-mounted solar systems in Colchester are permitted development for industrial and commercial buildings. Ground-mounted systems and installations on listed buildings usually require planning permission. We advise on planning requirements at the survey stage.
What is a G99 application and do I need one in Colchester?+
A G99 application is required for commercial solar systems above 16A per phase (typically above 3.68kW per phase for single-phase or above 11kW for three-phase). We handle all G99 DNO applications as part of our commercial solar service.
Can commercial solar include battery storage in Colchester?+
Yes. Commercial battery storage alongside solar allows businesses in Colchester to maximise self-consumption, manage peak demand charges and provide resilience against power cuts. We design combined commercial solar and storage systems.
