Cut operating costs, hedge tariff volatility.
We build commercial solar and storage against your half-hourly consumption profile — never a napkin estimate. The result: a system sized for what you actually draw during daylight hours, and a clear operating case for the finance director.
What you can check yourself.
Lumera designs and manages your project end to end. Every installation is delivered by our vetted network of MCS-certified installers — the certification that registers your system for Smart Export Guarantee payments — with electrical work signed off by NAPIT-registered engineers.
We're building our public review profile — ask us for recent client references.
Every project handled end to end.
One point of contact from feasibility through commissioning and O&M — no chain of subcontractors.
Site walk, roof structural check, half-hourly consumption modelling, indicative yield and payback.
G99 / G100 applications, DNO liaison, planning support where required.
Panel layout, string design, inverter selection, cable routing, monitoring and metering.
Scaffolding or MEWP, own installation crew, minimal disruption to operations.
Full electrical test pack, DNO sign-off, monitoring platform handover.
Optional O&M contract with response times and annual performance report.
Three routes, one asset.
Which one suits depends on your balance sheet, your tax position and how long you hold the sites. We'll model all three against the same generation figures.
You own the asset, keep the SEG income and claim the capital allowances. Best long-term return.
- You own the asset and keep every unit it generates.
- SEG or PPA export income stays with you.
- Capital allowances are claimable against the spend (see below).
- Highest lifetime return, and the system is on your balance sheet.
Fixed monthly cost, preserves working capital.
- Fixed, budgetable monthly rental instead of a capital outlay.
- Lease rentals are generally an operating expense — confirm treatment with your accountant.
- Option to purchase at the end of term on most agreements.
- Sits between CAPEX and PPA on both cost and control.
A funder installs, owns and operates the system; you buy the power at a fixed rate — typically 12–16p/kWh against 28–32p/kWh grid — over a 15–25 year term.
- No capital outlay and no maintenance liability — the funder owns and operates the asset.
- You buy the power at a fixed rate, typically 12–16p/kWh against 28–32p/kWh from the grid.
- Terms typically run 15–25 years, with indexation agreed at the outset.
- A sleeved PPA aggregates every site in a portfolio under one contract.
Commercial solar is special-rate plant, so it does not qualify for Full Expensing.
- The 100% first-year route is the Annual Investment Allowance (up to £1m per year).
- Spend above that attracts a 50% First-Year Allowance, with the balance written down at 6% a year.
- Commercial installations carry 20% VAT, usually recoverable by VAT-registered businesses.

Multi-site rollout.
For holiday parks, industrial estates and portfolio landlords, portfolios price differently to single sites. Funders quote against aggregate volume, so portfolio-scale finance and PPA pricing beats single-site terms.
Portfolio-scale volume moves you into a different bracket — funders price the portfolio, not the smallest roof in it.
One grouped operation and maintenance contract with shared response coverage, rather than a dozen standalone agreements.
Portfolio-level cover for the assets, priced once and spread across the estate.
A single rollout schedule, one commissioning standard and one reporting pack across every site.
How we choose which sites go first
- Roof area & condition
- Usable unshaded area, covering material, age and remaining life — we won't put a 25-year asset on a roof with five years left.
- Electrical capacity
- Incoming supply, board headroom and existing load, which sets the practical ceiling on array size.
- DNO region
- Connection cost and G99 timescales vary considerably by network operator; some regions are simply quicker to energise.
- Half-hourly consumption profile
- Daytime-heavy sites self-consume more and pay back faster. The profile decides the ranking, not the roof size.
Send us your portfolio and 12 months of half-hourly data for each site.
Request a feasibilityHoliday parks.
Parks are close to an ideal solar load: demand peaks across the summer daylight hours, spread over reception, amenity blocks, laundries, pools and pitch supplies — all behind meters you already pay standard commercial rates on.
Occupancy peaks in the months the array produces most, so self-consumption is high without a large battery.
Amenity blocks, reception, workshops and stores modelled as one system across the site.
Generation displayed for guests, and hard numbers for accreditation schemes and booking-platform sustainability listings.
Installation programmed for the closed period so trading weeks aren't disrupted.
- Panels distributed across amenity blocks, reception and a workshop roof.
- Offsets more than 25% of total site electricity across a full trading year.
- Modelled against a summer-weighted half-hourly profile.
- One amenity-block roof feeding laundry and shower-block demand.
- Sub-4-year payback on a high daytime self-consumption profile.
- No battery required — daytime demand absorbs almost all generation.
Both examples are modelled figures used to show the shape of a typical park scheme, not completed Lumera projects. Your numbers come from your own half-hourly data.
Cold store, Kent — 48 kWp + 40 kWh.
Roof-mount PV paired with a 40 kWh battery to cover early-morning compressor start-up. These are modelled figures from our feasibility method, not a completed installation — we'll publish signed-off client case studies with photography as projects complete.
