Generation vs use
50 kW on a closed building
Sized for capacity, then empty through the hours it would generate - with little or no export to recover the miss.
Solar built where it works
Independent pursue, conditional, or park verdicts - before survey spend, and before anyone with a contract to win has weighed in.
Our Mission
Our mission is to make the first decision cheap and certain, so more solar gets built on the roofs that pay for it.
Our values
We believe independence leads to verdicts you can defend.
We believe honesty when parking leads to budgets protected.
We believe board-ready evidence leads to decisions that stick.
We believe portfolio triage leads to capital where solar works.
We believe a fixed fee leads to no incentive to say yes.
We believe engineering seriousness leads to named next steps, not theatre.
Why this exists
Stage1Energy is new. The method is not.
It began as a research project - a model for deciding whether a commercial roof is worth building on, before anyone commissions a survey.
Modelled output has been compared against twelve months of metered generation.
What turned it into a business was what kept coming up in conversations with estates teams. Three things, over and over.
Portfolio stall
Pressure without answers
Net-zero pressure says install more. Across an estate the questions never get answered - which roofs to pursue, which to park, and on what evidence.
Wrong incentives
Reports that want yes
Data is missing, the reports on the table earn when more panels go up, or independent feasibility costs enough that the decision stalls for months.
Who runs Stage1Energy
Ted Evans
Founder. Civil engineer.
I built the model to answer the question that sits in front of every estates team before design or installation begins: does this roof actually work? Every report on this site is read and signed off by me before it goes out.
One person, deliberately
Stage1Energy is run by one person, deliberately. There is no account manager between you and the person who wrote the method, and no one in the process whose income depends on the answer being yes.
Lower the barrier
I built it to lower the barrier to implementing solar - not by selling panels, but by answering the question that sits in front of every estates and asset team before design or installation ever starts: does this roof actually work?
The decision comes first
UK design and installation are incredibly good. The hard step is the one before either of them. Design comes after you have already decided to proceed. Stage1Energy exists for that first decision: a fixed-fee, independent pursue, conditional, or park verdict - with the workings attached - so capital goes where solar works, and parks where it does not.
Installers earn when you build. We earn when you have a number you can defend.
Step 1
Feasibility
Decide whether to buy anything - and at what size.
Step 2
Design
After the decision. Layout, mounting, and tender baseline.
Step 3
Install
Where UK delivery is already incredibly good.
