Society Solar Credit Apportionment Calculator

A planning tool for RWAs: see roughly how a shared rooftop plant's generation splits across flats under two common apportionment methods.

There isn't a single UPERC-mandated formula for how an RWA splits shared solar credit internally, societies typically agree on either an equal split (every flat gets the same share regardless of size) or an ownership/consumption-weighted split (larger flats or heavier consumers get a proportionally larger share). This tool shows both so your RWA can compare before choosing. Confirm your society's approach is documented in its VNM agreement, see our Virtual Net Metering guide.
Estimated credit per flat
Equal split, per flat0 units/mo
Weighted split, your flat (at your share %)0 units/mo

Weighted result uses your entered share % directly against total generation, illustrative only, actual DISCOM crediting depends on your society's registered VNM agreement.
