Solar Panel Installation in Redruth

Solar Panels in Redruth: what a TR15 or TR16 roof generates

Redruth is where CCS Heating & Renewables is based: our office is at Unit 4, Pool Business Park (TR15 3QW), so every survey in Redruth, Pool, Illogan, Carn Brea, Lanner and St Day is a short drive. A south-facing roof in Redruth produces about 1,043 kWh a year for every kilowatt-peak installed, according to PVGIS, the European Commission's solar model. A typical 4 kWp system, about ten modern panels, therefore makes roughly 4,170 kWh in an average year.

Solar output in Redruth by roof direction

Figures are PVGIS 5.3 long-term averages for Redruth (SARAH-3 satellite data, 2005–2023, 14% system losses). Generation runs from about 129 kWh per kWp in May down to 32 in December, so a 4 kWp south roof makes around 500 kWh in a good summer month and about 130 in December. For the same model run for the far west, see our Penzance solar output figures.

Redruth roofs: what fits where

• Granite mining terraces (Fore Street, West End, Penryn Street): slate roofs, often south-facing on the rear elevation. Narrow spans usually mean 3–4 kWp rather than 6–8 kWp.
• 1930s semis & bungalows (Trewirgie, Sandy Lane): larger, often unshaded roof areas; 3.5–5 kWp is common.
• Tolgus, Illogan & Park Bottom estates: 1950s–70s semi-detached homes with simple, regular roof shapes — among the most straightforward installs in the area.
• East-west roofs: east and west faces each lose about a fifth against due south (see the table), but panels on both slopes spread generation across the morning and evening.

Planning in Redruth: the conservation area and the World Heritage Site

Roof solar on a house is usually permitted development if the panels sit no more than 0.2 m proud of the roof slope and no higher than the ridge. Redruth town centre is a conservation area, and the Camborne and Redruth mining district is part of the Cornwall and West Devon Mining Landscape World Heritage Site: there, panels on a wall or roof slope fronting a highway are not permitted development, so front elevations on streets like Fore Street need planning permission. Listed buildings always need planning permission and listed building consent. Rear slopes, which on most Redruth terraces are the south-facing ones, are usually fine. Our planning guide for renewables in Cornwall covers the detail.

Connecting to the grid in TR15 and TR16

The local network operator is National Grid Electricity Distribution (South West). A typical home system is notified to them after installation; larger systems, or a solar and battery system above the single-phase limit, need approval before installation. We handle that notification as part of the install, and the MCS certificate, G98 and SEG paperwork guide explains each document you should receive.

Costs

Residential solar panels and batteries carry 0% VAT until 31 March 2027. There is no Redruth-specific solar grant; see who qualifies for fully funded solar in Cornwall for the means-tested routes and their realistic odds, and our solar panel costs in Cornwall for typical prices by system size.
