REDUCING SOLAR PV SOFT COSTS
The report analyzes the cost gap between U.S. and German residential solar installations, finding that U.S. installation labor costs are significantly higher due to non-value-add activities, complex racking processes, and regulatory requirements. Through a 'time and motion' study of 26 sites, the authors identify opportunities to reduce costs by adopting one-day installations, simplifying racking bases, and innovating AC electrical circuits. The report argues that by removing non-value-add activities, U.S. installers could reduce soft costs by 30% and lower total system costs to $4.43/W.
