Estimate how much of a proposed rooftop solar system’s generation your business could use on site.
Business solar self-use estimator
Estimate how much of a proposed rooftop solar system’s generation your business could use on site.
Use matched interval totals in kWh from a generation estimate and a demand profile. The figures cover the uploaded period. The model excludes batteries, export limits, curtailment, investment and maintenance costs.
How to use the result
Pair estimated generation with site demand for the same intervals. Each row counts the lower of demand and generation as self-used electricity. Surplus generation counts as export and unmet demand as imports. Compare the resulting self-use percentage across scenarios based on different roof sizes or working hours.
What to enter
- Avoided import price (p/kWh) — for example, 24.
- Export price (p/kWh) — for example, 6.
