Commercial Solar & EV Charging UK — Combined Installation Solutions

Combine commercial solar panels with workplace EV charging to cut fleet charging costs by up to 90%. Solar-powered EV charging eliminates peak-rate grid electricity, generates OZEV Workplace Charging Scheme grants of up to £350 per socket, and future-proofs your business for the 2035 ICE ban. MCS and OZEV approved installers covering the whole UK.

Why Combine Solar with EV Charging?

Solar-generated electricity costs 4–6p/kWh versus 24–30p/kWh from the grid. A 50kW solar array powering 10 workplace EV chargers saves £15,000–£25,000 annually on fleet charging costs alone. Adding battery storage enables overnight charging from daytime solar generation, achieving near-zero fuel costs for electric fleets.

System Costs & Payback

Small fleet (10 chargers + 30kW solar): £45,000–£60,000. Annual savings £10,000–£15,000. Payback 3–5 years.

Medium fleet (20 chargers + 50kW solar + 50kWh battery): £90,000–£130,000. Annual savings £25,000–£35,000. Payback 3–4 years.

Large fleet (50+ chargers + 100kW solar + 100kWh battery): £200,000–£350,000. Annual savings £60,000–£100,000. Payback 3–4 years.

Frequently Asked Questions

Can solar panels power EV chargers directly?

Yes. Solar panels feed a common electrical distribution board alongside your grid connection. When solar is generating, EV chargers draw solar power first. Smart energy management systems automatically prioritise solar for charging, only drawing grid power when solar output is insufficient.

What grants are available for workplace EV charging?

The OZEV Workplace Charging Scheme provides up to £350 per socket (max 40 sockets per site). Combined with 0% VAT on solar installation and 100% Annual Investment Allowance on the full system, total incentives can reach 40–50% of project cost.

How many solar panels do I need for EV charging?

Each 7kW EV charger used for 4 hours daily needs approximately 8kW of solar capacity (20 panels). A workplace with 10 chargers needs a 50–80kW array. Adding battery storage allows a smaller solar array to serve the same number of chargers by storing daytime generation for afternoon/evening charging.

Solar EV Charging by Business Type

Hotels: Guest EV charging is now a booking differentiator. 78% of EV drivers say charger availability influences hotel choice. A 10-charger solar installation costs £30,000–£50,000 (after OZEV grants) and generates additional room revenue from EV-driving guests.

Warehouses & Logistics: Electric delivery fleet charging during solar hours eliminates 90% of fuel costs. A 100kW solar array charges 15–20 electric vans overnight via battery storage. Royal Mail, DPD, and Amazon are transitioning to electric fleets — their logistics partners need solar-powered charging infrastructure.

Office Car Parks: Employee EV charging powered by solar carport canopies combines parking shelter with energy generation and charging. Smart charging algorithms distribute solar power across 20–50 chargers based on employee departure times and solar availability.

Retail & Supermarkets: Customer EV charging increases dwell time by 25–40 minutes (average charge session), directly increasing basket spend. Tesco, Sainsbury's, and Lidl are installing solar-powered rapid chargers across their estates.

V2G — Vehicle-to-Grid Revenue

Vehicle-to-Grid (V2G) technology allows parked EVs to export stored energy back to the grid during peak demand. A fleet of 20 V2G-enabled vehicles connected to a solar-powered charging hub can earn £3,000–£8,000/year in grid flexibility payments. Combined with solar self-consumption during the day and V2G export during evening peak (4–7pm), the ROI on solar + EV infrastructure accelerates by 18–24 months.

Commercial Solar & EV Charging UK — Combined Installation 2026

Combining solar panels with EV charging cuts electricity costs by 70% and future-proofs your business for the 2035 ICE ban. Solar-generated electricity costs 3-5p/kWh vs 65-85p at public chargers. With OZEV grants (£350/socket, max £14,000) and 100% AIA tax relief, payback drops to 3-5 years.

Costs & Savings

Small (5 chargers + 30kW solar): £45,000-£65,000. Medium fleet (20 chargers + 100kW): £130,000-£180,000. Large logistics (50+ chargers + 250kW+): £350,000-£600,000. A 10-EV fleet saves £36,250/year vs public charging. V2G lets parked EVs export solar energy back to the building.
