Large roof, daytime demand
Warehouses, distribution, manufacturing and light industrial. Big roofs, high weekday load, usually the best solar case there is.
Demand rises with the shift and falls away at night. Most of the year the building is drawing power at exactly the hours the roof is generating, so very little of what a solar array makes needs to leave the site. Lighting runs for long hours over a wide floor, and any process load sits on top of that.
A large roof and a daytime load together are the strongest case in commercial property, because self consumption is what makes the payback rather than the export price. Lighting hours are long enough that replacement usually pays back on its own, and where a fleet is starting to charge, the import capacity question needs answering before anything is ordered rather than after.
Agreed capacity set years ago for a plant that has since changed, and paid for every month whether it is used or not. Roof condition and remaining life, which decides whether an array can go on at all. And the order of the work, because charging added before the array is sized changes what the array should be.
Add the building and a recent bill. The roof area and the weekday load together will tell you quickly whether solar is worth pursuing here.
Every measure we model is set out on what we cover, and how it works runs through the four steps.
