Solar Canopy & Car Park Solar
Installation in Exeter

Exeter and Devon receive above-average solar irradiance — approximately 1,050 kWh/m2 per year at optimal tilt — making solar canopy installations in the region more productive than equivalent systems in the Midlands or North. Combined with Exeter City Council’s net zero 2030 commitment and the city’s large concentration of commercial car parks, Exeter is a strong solar canopy market.

Why Exeter Businesses Are Installing Solar Canopies

Devon’s solar advantage is real. Exeter’s south-westerly latitude and proximity to the coast gives it consistent irradiance levels that improve solar canopy yields by 5-8% over the UK average. A 150 kWp system in Exeter generates approximately 157,500-165,000 kWh annually.

Key Exeter drivers:

• South West solar irradiance: Above-average annual radiation improves yield and shortens payback periods compared to northern England installations.
• Sowton and Marsh Barton: Devon’s largest industrial and trading estate concentrations. Many large-footprint sites with underutilised car park space.
• Exeter Science Park: Technology-focused businesses with strong ESG reporting requirements and high electricity consumption from servers and lab equipment.
• University of Exeter: Large campus with extensive car parking. PSDS grant eligible for solar canopy installation across student and staff car parks.
• Tourism and hospitality: Devon’s tourism economy creates demand for covered EV charging at hotels, leisure facilities, and visitor attractions.

Canopy Suitability by Area

Sowton Industrial Estate (EX2): Devon’s largest industrial estate, stretching along the M5 J29 corridor. Multiple large car parks and hardstanding areas suitable for 100-500 kWp systems.

Marsh Barton Trading Estate (EX2): One of the South West’s largest concentrations of trade counter, automotive, and manufacturing businesses. Flat car parks well-suited to mono-pitch canopy structures.

Rydon Lane Retail Park (EX2): Out-of-town retail destination with large surface car parks. 300-600 kWp canopy potential.

Exeter Airport Business Park (EX5): Growing commercial hub adjacent to Exeter International Airport. Light industrial and office mix with significant car parking provision.
