Additional revenue streams for community solar

Renewable Energy Credits and other potential sources of revenue could be modeled in SAM using a PBI. However, the PBI is treated as a reduction in operating expense so affects the LCOE. Need an option to add revenue streams that are treated as revenue rather than reduction in operating cost.

This is particularly relevant for the Community Solar model, where developers supplement revenue from subscription payments with revenue from other sources such as renewable energy credits (RECS). It also relevant for Single Owner and other front-of-meter financial models.

If using PBI to represent a REC, workaround to calculate LCOE is to run two simulations: 1) Set PBI to zero to calculate LCOE, then set PBI to REC to calculate NPV, IRR/PPA price.
