Where is the building?
Search for the area, use your location, or tap the map. Then move in close to your roof.
Tap your building to place the site.
How do you use electricity?
An average month from your bill is enough. Units give a better answer than the bill amount.
On your bill as “units” or “kWh”.
Includes demand charges and VAT, so it is less exact than units.
Energy charge ÷ units on your bill gives yours. Commercial and industrial rates are usually higher than the national average shown.
Filled in from your tracing. Leave out water tanks, stair rooms and shaded parts.
Power cuts and backup
Grid-tied solar switches off in a power cut. A hybrid system with batteries keeps chosen loads running. Leave these at zero if cuts are not a concern.
Monthly fuel and upkeep ÷ units the generator makes. Used to value solar during cuts.
