Capital committees see solar proposals regularly - and reject or defer many because the paper confuses a sales brochure with an investment case. A sound solar investment board paper does one job: it asks directors to approve a defined next step on the strength of independent feasibility, with risks visible and alternatives considered.
What the board is actually deciding
Clarify the approval ask before writing. Mixing stages confuses committees.
- Stage A - Confirmatory work
Authorise structural survey, roof inspection, and formal grid enquiry. Budget typically £5,000–£15,000.
- Stage B - Capital install
Authorise full project capex after surveys, quotes, and final design. Often six figures plus.
- Stage C - Portfolio programme
Approve feasibility spend across multiple sites and a capital envelope for tranche one.
- Feasibility first
Belongs before Stage A. Commission via site assessment or advance from waiting list.
A paper that smuggles full install approval behind a feasibility summary will get sent back.
Recommended paper structure
What boards actually need
A one-to-two-page recommendation with explicit ask and risks - not thirty pages of technical detail alone. Attach the full feasibility report as evidence.
-
Recommendation
State pursue, defer, or do not pursue in the first paragraph. Include estimated capacity, annual generation, payback or NPV, and total capex order of magnitude. Name the approval requested today.
-
Strategic context
Link to net-zero targets, energy cost volatility, tenant demand, or asset enhancement. One paragraph - boards do not need a climate essay.
-
Site summary
Address, building use, roof description, tenancy and lease notes, and why this site was selected. Map or aerial image helps.
-
Financial summary
Table format: capex, annual savings, payback, NPV, key sensitivities. State tariff, export, and self-consumption assumptions. Figures are feasibility-grade - see how to read a solar feasibility report.
-
Risks and mitigations
Structure, grid, planning, lease, and data quality - each with a mitigation. Example: “Structural capacity unconfirmed - mitigate via appointed engineer survey in approved budget.”
-
Next steps and timeline
What happens if approved: survey appointments, tender approach, target install window, responsible owner.
-
Evidence pack
Full feasibility report and optionally market context such as commercial solar feasibility in 2026.
Evidence the board should see
- IndependenceFeasibility, not installer quotes alone - feasibility vs quote.
- Written verdictWith conditions, not only spreadsheets.
- FlagsEngineering and grid at screening level - honest about what is unconfirmed.
- MethodologyLink or summarise modelling approach. Stage1Energy publishes methodology.
- LimitsFeasibility is not design or structural sign-off - vs design, vs survey.
Directors trust papers that say what could go wrong.
Financial presentation tips
Use organisation-familiar metrics. Show one sensitivity table: electricity price ±10%, self-consumption ±10%, capex ±10%. Avoid precision falsehood - “approximately five years, subject to tenant consumption confirmation” beats “4.37 year payback” from estimated load. Do not double-count benefits.
Portfolio papers
Portfolio approvals need a ranking table: site name, capacity, payback, NPV, verdict, proposed year. Explain screening methodology - portfolio solar feasibility screening - so directors know these are the best candidates, not the only ones considered.
Common reasons papers fail
Failure modes
No clear ask. “Note progress” achieves nothing. Installer quote as primary evidence. Missing lease or landlord angle. Ignored grid risk. Overstated generation certainty. Burying the verdict - recommendation must be visible on page one.
Using Stage1Energy reports in papers
Stage1Energy’s commercial solar feasibility reports are formatted for extraction: executive summary, financial tables, flags, and verdict. Fixed fee at join the waiting list, five working days standard delivery.
Lift the summary and tables into your template; attach the full PDF as appendix. Waiting list supports the portfolio narrative without full report cost on every address.
Closing the loop after approval
Record board conditions in the project file. If approval was “proceed subject to structural survey,” the next paper should open with survey results - not repeat feasibility verbatim.
Good board papers make the eventual install paper easier: feasibility answered “should we?” surveys answer “can we?” quotes answer “who and how much?”
Template language for conditions
Resolution tip
When feasibility returns “pursue with conditions,” mirror those conditions verbatim in the resolution text. Directors should vote on the same caveats the feasibility author documented - not a softened version that disappears from the minutes.
Examples: “approval subject to structural survey confirming ballast loading”; “approval subject to landlord consent under clause X”; “approval subject to G99 offer within £Y contingency.” If conditions fail, the paper trail should show why the project paused.
