Common Questions

Commercial Solar FAQs
for Welwyn Garden City

How much does commercial solar cost in Welwyn Garden City?+
Commercial solar pricing in Welwyn Garden City 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 Welwyn Garden City?+
Most commercial roof-mounted solar systems in Welwyn Garden City 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.

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 Welwyn Garden City?+
