Commercial Solar Installation in West Sussex
West Sussex hosts one of southern England's strongest mixed economies — Gatwick Airport, the aerospace cluster around Crawley, agricultural and horticultural production across the coastal plain, and creative industries in Chichester and Horsham. South-coast irradiance and London-adjacent electricity prices combine for excellent commercial solar returns.
The guides cover the county, from large-scale industrial estates to rural agricultural sites. Most installers start with a desk feasibility from your half-hourly meter data, often without charge — no site visit is needed for an indicative system size, output, savings and payback model. Once the numbers work, the installer's engineers attend a one-day site survey and return a fixed-price proposal — typically within 5–10 working days.
With commercial electricity rates around 31p/kWh and West Sussex solar yields of 950 kWh per kWp, a typical 100kW system saves approximately £29,500 per year — paying back in 3-4 years before generating profit for the remaining 20+ years of warranty.

Planning & Compliance Considerations
The South Downs National Park covers a substantial portion of West Sussex; rooftop commercial solar inside is normally permitted, ground-mount restricted. Coastal areas (Bognor, Worthing, Littlehampton) sit outside the National Park. Industrial sites at Manor Royal (Crawley), Slinfold, and the Worthing/Lancing corridor are largely unconstrained for solar installs.
West Sussex Commercial Solar FAQs
Why is West Sussex commercial solar so attractive?
South-coast irradiance (1,090 kWh/m²), commercial electricity rates of 31p/kWh, and a Gatwick-driven economy with high daytime power demand combine for 3–4 year paybacks. Manor Royal (Crawley) hosts major employers including Thales, Doosan Babcock, Elekta, and Boeing — all with substantial roof areas suitable for 250kW+ arrays.
Can solar be installed near Gatwick Airport?
Yes — and it's increasingly common. CAA glare guidance applies to installations within Gatwick's safeguarding zone. Installers model reflectance to demonstrate compliance. Several Gatwick-area logistics, hotel, and aerospace sites operate substantial solar arrays under standard CAA review.
Does the South Downs National Park restrict solar?
Inside the National Park, rooftop commercial solar is normally permitted but requires design that respects landscape character. Ground-mounted arrays face stricter scrutiny. Outside the National Park (Manor Royal, Worthing/Lancing, Bognor, Chichester industrial areas), standard permitted development rules apply.
Is solar viable for West Sussex horticulture?
Excellent fit for packhouses and refrigerated produce stores. Horticultural businesses on the coastal plain (around Chichester, Bognor) have constant daytime cooling loads. Solar combined with battery storage can offset 60–80% of grid electricity demand. Standard agricultural permitted development covers most rooftop installs on barns and packhouses.
What support exists for West Sussex businesses?
All UK incentives apply (AIA, SEG, VAT recovery for VAT-registered businesses, business rates exemption). Coast to Capital LEP and Sussex Chambers have funded low-carbon programmes. West Sussex County Council's Climate Strategy commits to facilitating commercial renewables. Ask your installer whether grant applications are included in project delivery.
