Choosing solar installers in Cornwall
A solar installation in Cornwall can involve a roof, an outbuilding or a separate ground-mounted array. Start your enquiry with the position you have in mind. Cornwall Council's solar guidance treats building-mounted and standalone equipment under different permitted development classes, so a quote for one layout does not settle the planning position for another.
Ask each installer to explain the proposed mounting system and estimate generation for that exact position. For a roof installation, include an assessment of the existing roof and any strengthening work in the scope. Cornwall Council specifically highlights roof strength and electrical work in its building-regulations guidance. For a standalone design, ask for cable routes and groundworks to be priced separately.
Check the address and proposed layout with the council before work begins if consent requirements are unclear. The council offers advice on whether planning permission is needed and explains the role of a Lawful Development Certificate. Listed buildings and other property constraints need individual attention.
Compare like-for-like proposals on TopGreenDeals. Send your shortlist the same site photographs, annual electricity use and preferred panel location. Ask who will handle the necessary approvals and what evidence you will receive when the installation is complete.

Frequently asked questions
- Can I choose ground-mounted solar panels in Cornwall?
- Ask an installer to survey the proposed position and price the mounting, cabling and groundworks. Cornwall Council distinguishes standalone solar equipment from equipment on buildings; check which planning conditions apply to your layout before work starts.
- What roof checks should a Cornwall solar quote include?
- The council highlights the need to assess whether the existing roof can carry the panels. Ask the installer to state who will assess the roof, whether strengthening is needed and how roof work and electrical compliance are included in the price.
- What happens during a solar panel survey in Cornwall?
- The survey gives an installer the information needed to design your system: roof dimensions and condition, shading, access, cable routes and the electrical supply. The resulting proposal should show the panel layout, equipment locations and the work included in the price.
