Solar EV Charging for UK Businesses: The 2026 Business Case
How UK businesses can combine solar PV with EV charging to reduce energy costs. ROI analysis, battery storage and OZEV grant eligibility.
Combining solar EV charging with a commercial EV charger installation is one of the most financially compelling investments for UK businesses in 2026. This guide covers how solar PV integrates with commercial EV charging, the ROI calculation, WCS grant stacking strategies and how to find an OZEV-approved solar EV charger installer.
Combining solar PV with EV charging is one of the most financially attractive investments for UK commercial properties in 2026.
How solar EV charging works
Solar-optimised chargers (such as myenergi Zappi) divert surplus solar generation to vehicles at ~£0.05/kWh vs grid electricity at £0.28–0.35/kWh.
Grant stacking
Combine WCS grants (£500/socket) with smart export guarantees to significantly improve payback periods.

How Solar EV Charging Commercial Works for Commercial Properties
Solar-optimised EV chargers (such as the myenergi Zappi) monitor your site's solar generation in real time and divert surplus energy directly to connected vehicles — rather than exporting it to the grid at low rates. This means your EVs charge using electricity you have generated at a marginal cost of ~£0.05/kWh, compared to grid electricity at £0.28–0.35/kWh. For businesses with significant solar generation, this can reduce EV charging costs by 60–80%.
Solar EV Charger Installation UK — What Does It Cost?
A commercial solar PV installation (50–100kWp) costs £40,000–£80,000 before grants. Adding solar-compatible EV chargers (e.g. Zappi 22kW x 4) adds £8,000–£15,000 including installation. WCS grants cover the EV charger element. SEG (Smart Export Guarantee) tariffs provide additional income from surplus solar exported to the grid.
WCS Grant Stacking with Solar PV — Maximising Your Funding
Businesses can combine the Workplace Charging Scheme grant (up to £500/socket for EV chargers) with solar PV incentives simultaneously. The WCS applies to the EV charger installation cost regardless of whether solar PV is also being installed. For a 10-socket installation, this represents up to £5,000 in WCS savings on top of any solar grants or tax incentives. Your OZEV-approved installer can advise on grant stacking.
Battery Storage Integration with Commercial EV Charging
Adding battery storage to a solar + EV charging system allows surplus solar generation to be stored and used for overnight EV charging — maximising self-consumption and reducing grid import further. Commercial battery systems (30–100kWh) cost £15,000–£45,000 but can dramatically improve ROI by eliminating peak-rate grid electricity usage entirely.
