Solar that's designed around your half-hourly load — not your roof.
Most commercial solar projects under-deliver because they're sized to fill a roof instead of matching consumption. TUS designs around your load profile, removes the take-or-pay clauses that penalise solar, sets up export value properly, and monitors the lot via Yolk.
- 6 funding routes
- CapEx, PPA, EaaS, leasing, grants…
- Zero
- Volume-tolerance penalty on supply
- 100%
- REGO-backed top-up available
The solar your supply contract approves of
Generation is only part of the answer. The contract, the export metering, the grid top-up and the reporting are the other 60%.
Generation that's actually optimised
We design solar around your half-hourly consumption profile — not a roof-fill quote. That means more of the generation displaces grid imports, and less is exported at low export rates.
Export value, properly extracted
We set up proper export metering and negotiate export tariffs (Smart Export Guarantee or bespoke) so every kWh you push to the grid earns a fair rate.
Zero-volume-tolerance supply contract
Standard take-or-pay clauses penalise you for using less grid energy. We arrange a supply contract with zero volume tolerance, so solar can't breach your contract terms.
MOP & DC sorted
Half-hourly metering needs Meter Operator and Data Collector contracts. We arrange both and feed the data into Yolk so you actually see what your panels are doing.
REGO-backed top-up
For grid power you still draw — at night, in winter — we arrange a REGO-backed renewable supply contract. End result: a 100% renewable electricity claim, audited.
Reported in your SECR
Generation, export and CO₂e avoided flow into your annual SECR and ESG reporting automatically. Your finance team doesn't have to chase the numbers.
Six funding routes — pick the one that fits the balance sheet you have.
Funding isn't one-size-fits-all. We model each option against your financials so you choose with eyes open — not under installer-led pressure to pick the route that suits them.
CapEx (own balance sheet)
Fastest payback, full ownership, eligible for Enhanced Capital Allowances and the Smart Export Guarantee.
Power Purchase Agreement (PPA)
No upfront. A third party funds, installs and maintains the system; you buy the power generated at a fixed rate, typically below market.
Asset finance / green loans
Spread the cost over the asset life with predictable repayments. Often tax-advantaged.
Energy as a Service (EaaS)
TUS sources the kit, installs it, and shares in the savings. No CapEx, performance accountability with the provider.
Lease / rent-a-roof
A third party leases the roof, installs panels and pays you a rental or shares the savings. No capital required.
Government incentives
SEG export payments, ECA tax relief, and local grants where available. We layer these on top of any funding route.
Take-or-pay clauses can kill your solar payback. We remove them.
Standard commercial supply contracts often include volume tolerance (typically ±10% of forecast). Drop below the band — because your solar is producing — and the supplier charges you for unused energy. That can wipe out the financial case for solar in year one.
We refuse to install solar on a site with this clause active. Where it exists, we renegotiate the supply contract first and arrange a zero-volume-tolerance term, so your panels can do their job.

From survey to first sunny morning
We project-manage end-to-end. You sign three things — the feasibility, the contract, the install. We do the rest.
- 1
Site & load survey
Roof structure, electrics, half-hourly load profile. We size the system to your demand, not the roof.
- 2
Engineering & financial model
Yield model, displaced grid import, export earnings, payback under each funding option, ESG impact.
- 3
Contracts & funding
PPA or CapEx, supply contract with zero volume tolerance, MOP/DC, REGO-backed top-up. Drafted and explained.
- 4
Install & commission
Project-managed install with minimum operational disruption. Sub-meters and Yolk dashboards from day one.
- 5
Operate & optimise
Generation reported monthly. Load-shifting and battery upgrades modelled when the data warrants them.
Move from a single price-fix to a portfolio you actively manage.
Our trade desk currently manages over 150 GWh in flex contracts on behalf of UK businesses, and beat supplier projections by 20% in the last 12 months. You stay in control. We do the trading.
