Commercial Solar Panels in Sussex

Commercial Solar for Sussex Business

Electricity is one of the largest fixed overheads a Sussex business carries — and one of the few you can genuinely take control of. Commercial solar panels turn your roof or land into a generating asset, cutting your day-to-day energy costs, protecting you against future price rises, and cutting the carbon footprint your customers and tenders increasingly ask about.

Greener Solar Solutions designs and installs commercial solar across East Sussex, West Sussex and the wider South East — for warehouses, industrial units, offices, retail premises, farms and agricultural buildings. As part of A Greener Alternative Ltd we have a long track record helping both homes and businesses across Sussex move to cleaner, cheaper energy, and we are MCS certified, NICEIC approved and TrustMark registered.

From a 10kWp rooftop array to a 250kWp+ system across a warehouse or farm, we handle the whole project with our own directly employed engineers.

Why Sussex Businesses Are Going Solar

  • Cut your energy bills — offset a large share of daytime consumption, often a five-figure annual saving.
  • Fast payback, long life — large unshaded commercial roofs scale efficiently; typical payback 4–7 years, then a decade+ of near-free power over a 25–30 year life.
  • Tax-efficient — solar is plant and machinery; UK companies can typically claim capital allowances (including full-expensing style first-year relief for qualifying spend). Ask your accountant.
  • Export income — surplus earns via the Smart Export Guarantee or a commercial PPA.
  • ESG & tenders — supports SECR carbon reporting, net-zero goals and procurement scoring.
  • Price certainty — every kWh you generate is one you don’t buy at a volatile grid price.

Who We Install For

  • Warehouses & industrial units — large roofs, big arrays, strong economics.
  • Offices & retail — daytime consumption matches solar generation closely.
  • Farms & agricultural buildings — barn roofs and high daytime loads (refrigeration, milking, grain drying, irrigation) make agricultural solar one of the strongest payback cases in Sussex.
  • Hospitality, schools & community buildings — steady daytime demand and a visible sustainability story.

How Much Does Commercial Solar Cost?

Commercial solar is priced per installed kilowatt-peak (kWp), and the rate falls as system size rises. As a broad guide to typical UK installed pricing:

System size Typical use Indicative installed cost Rough annual saving*
10–30 kWp Small office / shop / farm outbuilding £8,000 – £30,000 £2,000 – £6,000
30–100 kWp Larger office / small warehouse / farm £25,000 – £80,000 £6,000 – £18,000
100–250 kWp+ Warehouse / industrial / large agricultural £80,000 – £200,000+ £18,000 – £45,000+

*Savings depend on your consumption pattern, tariff and how much generation you use on site vs export. Figures are approximate market ranges — we provide a modelled, fixed proposal after your free site survey. Commercial VAT differs from domestic: VAT-registered businesses can normally reclaim VAT, so the 0% domestic rate does not apply.

Commercial Solar FAQs

How much do commercial solar panels cost?

Commercial systems are priced per kWp and scale with size — roughly £8,000 for a small 10kWp array up to £200,000+ for a 250kWp+ warehouse or farm system. We provide a modelled, fixed proposal after a free site survey.

What is the payback period on commercial solar?

Typically around 4–7 years, depending on your consumption pattern, tariff and how much generation you use on site. Panels then keep producing for 25–30 years.

Can my business claim tax relief on solar panels?

Solar is plant and machinery, so UK companies can usually claim capital allowances on the investment — including first-year/full-expensing style relief for qualifying expenditure at the time of writing. Confirm the specifics with your accountant.

Do you install solar on farms and agricultural buildings?

Yes. Barn and outbuilding roofs, and high daytime agricultural loads, make farm solar one of the strongest payback cases in Sussex. We install agricultural systems across the county.

Will installation disrupt our operations?

We plan around your business — phasing work, scheduling around opening hours, and coordinating roof access to keep disruption to a minimum.

How does VAT work for commercial solar?

Unlike domestic installs (0% VAT), commercial solar is standard-rated, but VAT-registered businesses can normally reclaim it. We set out the VAT position clearly in your proposal.

Can we add battery storage or EV charging?

Yes. Battery storage lets you use daytime surplus in the evening or shift load off peak, and solar pairs naturally with EV fleet charging. We design these together where it makes sense.
