Written verdict
Pursue, pursue with conditions, or park - with the assumption that would change it. A decision you can put in front of a board.
Stage1Energy
Independent feasibility. Join the waiting list.
Know which roofs are worth pursuing before you survey. Register interest - we open capacity in order.
“You’ve sold me on speed alone.”
“I thought I would only do one, but it opened my eyes to how much solar potential my assets have.”
What an assessment includes
Every dossier answers the same questions - so a park is as useful as a pursue.
25-year financials
Green Book DCF with NPV, IRR, payback, and cashflow from stated assumptions. CAPEX as a band - not a theatre number.
Roof geometry & shading
Satellite imagery and LiDAR build a 3D environment. Geometry and near-field shading feed the yield model - live in the report.
Engineering flags
Wind, structure, DNO, and planning screening - with named next steps. Formal sign-off stays with the right professionals downstream.
Independence
No panels sold, no referral fees, no design work taken. The same standard whether the answer is yes or no.

Questions
FAQ
How do I join the waiting list?
Use the form on this page. Tell us roughly how many roofs you are weighing and we will register your interest.
What does an assessment include?
25-year Green Book DCF, self-consumption modelled against your actual load, and four engineering flags: wind, structure, DNO and planning. Compared against twelve months of metered output from operating commercial rooftop PV. Formal structural clearance, detailed design, DNO application and procurement are out of scope. See what an assessment includes.
Do you assess portfolios?
Yes. Every building gets a full dossier. Register interest via the waiting list and tell us roughly how many roofs you are weighing.
Is Stage1Energy independent of installers?
Yes. Stage1Energy does not install, procure, or design systems. No panels sold, no design work taken, no referral fees.
Do you need a site visit?
No site visit is required to start. Send the site address and any consumption data you have. The assessment is remote and evidence-based - satellite imagery and named, published sources. A physical survey is downstream: feasibility decides whether that survey is worth commissioning.
