Offices, hotels, schools & clinics
Commercial solar sizing
Daytime demand, met by daytime sun.
Offices, shops, hotels, schools and clinics use most of their energy while the sun is up. Size a system that carries that load, rides through outages and backs up what cannot stop.
Typical loads we size for
The approach
Sized from what you actually run.
Import a load schedule
Upload your load list from a spreadsheet template instead of typing it in — every line keeps its quantity, power and hours.
Diversity built in
Not every load draws at the same instant. The engine applies a diversity factor to the peak demand it reports.
Grid, generator or both
Choose grid-tied, hybrid or off-grid, with or without a generator, and the system type changes the arithmetic — not just the label.
Report your client can read
Share a clean report link, print it, or download the bill of materials as a CSV for quoting.
Four steps
From load list to bill of materials.
-
01
Choose the site
Home, office, commercial building or industrial plant — then start from a ready scenario or a blank list.
-
02
List the loads
Appliances with quantity, power and running hours, split between sun hours and night. Or import a spreadsheet.
-
03
Set backup & supply
Grid-tied, hybrid or off-grid, single or three-phase, generator or not — and how long the essentials must run.
-
04
Get the system
Inverter, battery and array, string layout, matched products and a bill of materials — saved and shareable.
Commercial FAQ
Good questions.
What size range does the tool cover?
From a 1 kW single-room supply up to 1 MW of inverter output. Systems above the residential band are flagged for an engineering review, as they should be.
Can I size only the critical loads?
Yes. Size the whole building, or only the lighting, IT, refrigeration and safety loads that must stay up during an outage.
Does it produce a bill of materials?
Yes. Every sizing lists the inverter, battery and panel counts plus balance-of-system items, which you can export to CSV.
