The Enterprise Guide to Commercial Solar

For an enterprise, solar is not a rooftop decision — it is a procurement, finance and risk decision that happens to involve a roof. Treating it that way is the difference between a token array and a portfolio-wide asset that materially reshapes your energy cost curve for twenty-five years.

Start with the load, not the roof

Every credible deployment begins with interval data. Fifteen-minute consumption records reveal when your demand actually peaks and how well solar generation aligns with it. Sizing to self-consumption — not to roof area — is the single most important decision, because exported surplus is worth a fraction of avoided import.

Sequence the portfolio

Multi-site operators rarely deploy everywhere at once. We rank sites by return — factoring tariff, roof condition, load shape and grid headroom — then sequence rollout so the strongest assets fund the next wave. This turns a daunting capital programme into a self-reinforcing one.

Choose the right capital structure

• Outright purchase — strongest lifetime return, captures all incentives and depreciation
• Power purchase agreement — zero upfront, pay only for generated energy below grid rates
• Operating lease — off-balance-sheet flexibility with fixed, predictable payments

There is no universally correct answer; the right structure depends on your balance sheet, tax position and appetite for ownership. We model each side by side so the board sees the trade-offs in plain numbers.

Govern the asset

Procurement does not end at commissioning. Live monitoring, scheduled maintenance and yield benchmarking protect the return you signed off on. An enterprise array is a productive asset, and like any asset it rewards active management with decades of dependable, low-cost stellar power.
