Frequently Asked Questions

Common questions about solar installation in Essex
Do you install solar panels across all of Essex?
Yes, we cover the whole of Essex including Basildon, Chelmsford, Colchester, Southend-on-Sea, Brentwood, and all surrounding areas. We also work across the wider South East and UK.
Most residential solar installations fall under permitted development rights and don’t require planning permission. For listed buildings, conservation areas, or commercial properties, we’ll guide you through any requirements during our free feasibility assessment.
A typical residential installation takes 1-2 days once scaffolding is in place. Commercial installations vary depending on system size but are usually completed within 1-2 weeks. We minimise disruption throughout the process.
Yes, we offer flexible finance options for both residential and commercial customers. Residential customers can access competitive finance through Hometree, while commercial clients can explore PPA (Power Purchase Agreements), hire purchase through Astmoor Finance, or outright purchase.

Most roofs are suitable for solar. During our free feasibility assessment, we evaluate roof orientation, pitch, shading, and structural suitability. South-facing roofs are ideal, but east/west orientations can also work effectively with modern panels.

Yes, all our installations include smart monitoring so you can track performance. We also offer maintenance packages and are available for any support you need after installation.
We only install Tier 1 solar panels and premium inverters from trusted manufacturers like Growatt. This ensures maximum efficiency, reliability, and long-term warranty protection for your investment.
