Cost of capital
Your internal hurdle rate versus funder pricing.
Commercial structures
Solar funding, PPAs and business cases
Own it, lease it or buy the power — the right structure depends on your balance sheet, not the technology.
The same array can produce very different outcomes depending on how it is funded. We model the realistic routes side by side so the decision is made on cost of capital, risk appetite and control — not on whichever structure a single supplier happens to sell.
Capital purchase
The lowest lifetime cost per kWh and full ownership of the asset, the generation and any export revenue. It uses balance sheet capacity and puts performance risk with you — which is manageable with a properly specified O&M contract and monitoring.
Lease and asset finance
Spreads the capital over the asset life while retaining most of the economic benefit. Useful where capital is rationed against core operations but the business still wants long-term ownership.
Power purchase agreements
A funder installs and owns the system, and you buy the generated power at an agreed rate, typically below your delivered import price. No capital outlay and no performance risk — in exchange for a long-term contract, a lower total saving and constraints on the roof or land for the term.
PPAs suit some businesses very well and others poorly. We read the terms that matter: indexation, availability guarantees, buy-out schedules, roof access, assignment on sale and end-of-term obligations.
The business case we produce
Every review ends with a comparable model: capital cost, annual yield, self-consumption, savings under multiple energy price scenarios, payback, IRR, lifetime net benefit, carbon reduction and the sensitivities that would change the answer.
What we assess
The checks behind the recommendation.
Balance sheet treatment
On or off balance sheet, and what your lenders expect.
Contract length
How a 20–25 year commitment sits with property tenure and site plans.
Property implications
Roof access, landlord consent, sale and assignment provisions.
Performance risk
Who carries yield shortfall, and what the guarantees actually promise.
Exit terms
Buy-out pricing, decommissioning and end-of-term ownership.
