A comparison of the annual PV credit columns under Optimal Output - Simulation Utility Bills reveals that it does appear to be adjusted by inflation and utility rate multipliers annually. However, the calculated credit is not equal to the excess generation multiplied by the net metering rate. My report shows:
**Input - Site Screen**
Electricity Marginal Rate $0.02275
Electricity Average Rate $0.2388269
Electricity PV Production Type NetMetering
Electricity Net Metering Annual Excess Sellback Rate Type UserSpecified
Electricity Net Metering Annual Excess Sellback Rate of $0.03
**Output - End Use Graph Metrics**
Site Energy Use PV E 17.84 MMBTU/yr (4,865 kWh/yr)
Net Meter * Excess PV = $146, but the PV credit for year 1 in Optimal Output - Simulation Utility Bills is listed as $1,264. Even using the average electricity rate only nets $1,161.
