How to Use This Calculator

Enter the system capacity in kW DC and peak sun hours for your location.
Set the REC or SREC market price per MWh for your state.
Enter aggregation or broker fee percentage and annual degradation rate.
Set contract length and expected REC price escalation per year.
Review Year 1 net REC revenue and lifetime net revenue to evaluate the contract offer.

How the result changes with System capacity (kW DC)

System capacity (kW DC): Installed DC solar capacity.
Peak sun hours (PSH): Average daily peak sun hours.
System derate factor: DC-to-AC system efficiency.
REC price ($/MWh): Current SREC or REC market price. Ranges from $1 (voluntary) to $400+ (NJ/MA).
Aggregation/broker fee (%): Fee charged by REC aggregator or broker.
Annual degradation (%): Annual module power output decline.
Contract length (years): REC contract or analysis period.
REC price escalation (%/yr): Annual change in REC prices. Can be negative if market is declining.

Year 1 net REC revenue ($): First-year REC income after broker/aggregation fees.
Year 1 production (MWh): Number of RECs generated in year 1 (1 REC = 1 MWh).
Year 1 gross REC revenue ($): REC revenue before fees.
Lifetime net REC revenue ($): Total REC income over contract period after fees.
Lifetime gross revenue ($): Total REC income before fees.
Lifetime RECs generated: Total MWh of RECs over contract period.
Year 1 CO2 offset (metric tons): Annual carbon dioxide offset based on EPA grid average.
Lifetime CO2 offset (metric tons): Total carbon offset over contract period.
Avg REC revenue ($/kW/yr): Average annual REC revenue per kW of installed capacity.

Identify Input Parameters
4 parameters
System capacity (kW DC) = 500, Peak sun hours (PSH) = 5, System derate factor = 0.8, REC price ($/MWh) = 40 = 8 input(s) provided
Calculate Year 1 net REC revenue
Year 1 net REC revenue = year1GrossRecRevenue - year1AggregationFee
26280 = $26,280
Calculate Year 1 production
Year 1 production = year1ProductionKWh / 1000
730 = 730
Calculate Year 1 gross REC revenue
Year 1 gross REC revenue = year1ProductionMWh * recPricePerMWh
29200 = $29,200
