Solar panels for dealerships, FAQs

Yes, and the two work well together: charger demand is daytime-weighted, so solar feeds it directly. A sound design sizes the array for today's load plus the EV roll-out, and adds battery storage where the charging peak runs into the evening.

Showroom and workshop roofs usually provide ample area, and a forecourt or car-park canopy can add more. A sound design is sized against showroom lighting, air handling and workshop equipment, which together make a substantial daytime load.

It can help. On-site generation reduces the electricity bought from the grid and can support any Scope 2 reporting your franchise requires, alongside the running-cost saving and the customer-facing EV and sustainability story. Check whether your franchise agreement or the manufacturer's retailer standards set any requirements for renewables, EV-charger provision or signage; if they do, agree panel and charger positions with the manufacturer before design.

It depends heavily on the site. A pub or small restaurant (10-100 kW) typically costs £10,000-£90,000; a gym or golf clubhouse (30-250 kW) £28,000-£220,000; a car dealership (50-400 kW) £45,000-£350,000; and a supermarket or shopping centre (200 kW-2 MW) £150,000-£1.6m. These are indicative planning ranges. Cost per kW is roughly £750-£950 for systems above 250 kW, falling toward £600/kW above 1 MW. Most single-site systems fall within the £1m Annual Investment Allowance, which usually means 100% relief in year one for a business under the limit (solar is special-rate plant, so full expensing does not apply).

Because dealerships use most of their electricity during daylight hours, exactly when panels generate. Showrooms need cooling and lighting through the working day, workshop ramps and compressors pull power when the bays are busy, and forecourt and signage lighting run from first light. That daytime demand means a high share of what the panels make is used on site, which is worth more than exported electricity.

Indicatively around 5.5 years on a simple basis, on the assumptions on the cost page. A dealership's showroom, workshop and charging load is mostly daytime, so a high share of what the panels generate can be used on site. Tax relief such as the Annual Investment Allowance can improve the year-one position. Treat the figure as an indicative planning range, not a guarantee.

Yes, with landlord consent and a wayleave or licence to alter. A higher minimum energy standard than EPC E for privately rented non-domestic property has been consulted on, but no date is confirmed. Some landlords may still want PV because it can protect the value and lettability of their asset, and some fund it directly and recover through the service charge or a green-lease rent share. Check the lease, get the landlord's consent in writing before design, and compare tenant-funded and landlord-funded routes.

A dealer group can use one repeatable template, rooftop PV, optional car-park carport, and EV charging, then roll it across the estate with standard surveys, standard hardware and a single monitoring dashboard. Multi-site rollouts may attract portfolio pricing and a phased capital plan, so ask any installer whether they offer these, and a single point of contact. Large multi-site estates can deploy a single design across many premises this way.

It depends on whether the building is listed. A conservation area does not by itself remove permitted development for a roof array in England (Class J), although wall-mounted panels fronting a highway are not permitted there. Class J does not apply to a listed building or its curtilage, or to a scheduled monument, so a listed building needs Listed Building Consent and it is worth engaging the conservation officer early. Roof slopes hidden from public view, low-profile all-black panels, or solar carports and outbuilding roofs that avoid the protected frontage are options to discuss. Where the main building genuinely can't take solar, ground-mount on suitable land or a car-park carport may be an alternative, though a solar carport is a structure in its own right, so check planning with the council before design.

Solar carports can be one of the strongest options where roof area is limited. They turn an otherwise dead car park into generation, give customers shaded and EV-ready parking, and make a visible sustainability statement at the entrance. They suit dealerships with large customer or staff car parks where roof area is limited. A solar carport is a structure in its own right, so check planning with the council before design, and assess the car park alongside the roof.

Yes, they're stronger together. Daytime EV charging for staff, fleet, demonstrators or customers absorbs solar at 100% self-consumption, the most valuable kWh on the system. PV and chargepoints can be designed as one project. The Workplace Charging Scheme grant covers up to 75% of purchase and installation cost, up to £500 per socket (£350 before 1 April 2026), up to 40 sockets per applicant, but the scheme closes on 31 March 2027, so apply well before then. For a business the chargepoints can only be used by its staff and fleet, and parking solely for customers is ineligible, so customer-only charging on a forecourt is not WCS-eligible; check whether demonstrator vehicles count as fleet.

100% Annual Investment Allowance gives up to 25% effective tax relief in year one (solar is a special-rate asset, so use AIA or the 50% First-Year Allowance, not full expensing). The Smart Export Guarantee pays for exported power. The Workplace Charging Scheme can fund staff and fleet EV chargepoints. The right combination depends on the business, so check each scheme's own eligibility rules and apply through its official route.

The Minimum Energy Efficiency Standard currently requires at least EPC E to let commercial property in England and Wales, and a higher minimum standard has been consulted on, but no date is confirmed. Check the EPC rating of any leased premises. On-site solar can improve the EPC rating and may help protect the lettability and value of leased units, which is one reason landlords may support or fund installs.

If you're a 'large undertaking', 250+ UK employees, or turnover above £44m and balance sheet above £38m, then yes, the Energy Savings Opportunity Scheme (ESOS) applies. The phase 4 qualification date is 31 December 2026, and the notification of compliance is due by 5 December 2027. Larger dealer groups may be in scope. On-site solar is one of the most credible recommendations an ESOS audit can identify, and reduces metered grid consumption directly.

Rooftop installs almost never require closure. Work can usually be scheduled around a trading pattern and carried out in zones, and the only outage needed is the final grid connection, which can be booked for a quiet period or planned shutdown. Ask any installer how they will work around workshop hours and busy sales days. Solar carport builds happen in the car park with minimal impact on the building itself.

From contract to commissioning, expect several months. Physical install is typically several weeks depending on size. The longest item is grid connection, G99 takes many months from DNO submission on capacity-constrained networks, so the application is normally submitted alongside the structural survey to start the clock immediately. Multi-site rollouts run in phases over a longer programme.

Almost all of them: trapezoidal/profiled metal (clip or rail fix), standing-seam metal (clamp fix, no penetration), single-ply membrane and built-up felt on flat showroom and workshop roofs (ballasted), and concrete. Asbestos cement roofs (common on older roofs and outbuildings) can't be retrofitted and need replacement first. Where roof area is limited, solar carports, forecourt canopies and ground-mount are alternatives, though a solar carport is a structure in its own right, so check planning with the council before design.

Check what your franchise agreement and the manufacturer's retailer standards require. They may set requirements for renewables, EV-charger provision or signage; if they do, agree panel and charger positions with the manufacturer before design. Solar plus demonstrator and staff charging can self-consume daytime generation, and the Workplace Charging Scheme grant can offset the cost of staff and fleet chargepoints (parking solely for customers is ineligible).

Maintenance normally means annual O&M (electrical inspection, inverter firmware, panel wash if needed) plus 24/7 remote monitoring with automated underperformance alerts. For multi-site estates a single dashboard can cover every location with live generation, lifetime kWh and CO2 saved, useful for both facilities teams and ESG reporting. Typical O&M is £8-£12 per kW per year above 250 kW (an indicative range).

Yes. PPAs (power purchase agreements) provide solar with zero capex, you pay per kWh consumed below your current grid tariff, typically with savings from day one and the system off your balance sheet. Asset finance puts the system on balance sheet but spreads cost over several years and is cash-positive from year one only where the energy saving exceeds the repayments. Operating leases are also available, which suits estates wanting predictable per-site monthly cost.
