Note: National average residential solar cost is $2.50-3.50/W installed. Module costs have dropped below $0.30/W wholesale. Soft costs (permitting, labor, overhead) represent 50-65% of total installed cost.
Reference
Total Cost = Modules + Inverter + BOS + Soft Costs
Cost/Watt = Total Cost / (System Size x 1000)
Module $/W = Module Cost / Watts
Hardware % = (Modules + Inverter + BOS) / Total x 100
