About Commercial Solar EV
One site about one idea: solar generation and EV charging belong in the same design, the same grid application and the same business case.
Why the combination needs its own specialists
Solar installers size arrays to buildings. Charging installers count sockets. Neither discipline, practised alone, answers the question fleet and facilities managers actually face: what does this site's energy system look like with vehicles in it? The combined answer involves generation modelling, parking-schedule analysis, dynamic load management, one carefully-sequenced DNO engagement and a grant application — and getting it wrong in either direction is expensive. This site documents how the combined projects are done properly: the business case, the engineering, the regulations, the WCS grant and the depot-scale playbook.
How the free feasibility works
Data first, hardware last. The free feasibility offered on this site is a desk study built from twelve months of half-hourly meter data, your vehicle or staff-charging expectations and the site address: array sizing, socket plan, load-management approach, grid headroom read, grant eligibility and the whole-system cash flow, delivered in writing within seven working days. No site visit is needed for that first pass and nobody telephones you uninvited — the process is form-first from the quote page onwards. If the combined numbers don't clear your hurdle rate, the feasibility says so plainly, and sometimes it recommends solar-only or charging-only where that is honestly the better project.
What to ask of an installer
Commercial Solar EV is not an installer and holds no installer accreditations, so check whoever you appoint: MCS certification for the solar (needed for Smart Export Guarantee payments), OZEV authorisation for the chargepoints (needed for the Workplace Charging Scheme), a competent-person scheme registration such as NICEIC or NAPIT for the electrical work, and an insurance-backed workmanship warranty. Specification points worth insisting on: OCPP-compliant chargers, dynamic load management with intake metering, a solar-following configuration proven at commissioning, and a witnessed demonstration that the site holds under its supply limit with every socket active. Ask for an as-built pack and monitoring that reports solar share of vehicle energy, building self-consumption and pence per mile. How this site is researched and paid for is set out in the editorial policy.
What we won't tell you
That solar makes fleet charging free — it doesn't; it makes it 30–60% solar on daytime-dwell fleets and decisively cheaper either way. That nameplate charger ratings require a supply upgrade — they almost never do once load management is designed in. That V2G revenue is bankable today — our V2G page gives the honest 2026 position. The numbers on this site are taken from published government and industry sources and current scheme rules, and corrections are welcome.
