Through a design charrette with industry experts, the report proposes a 'systems approach' focusing on physical design, business processes, and industry scaling to reduce BoS costs to $0.60–0.90/watt. Key recommendations include optimizing structural designs to reduce wind forces, rethinking electrical architectures through high-voltage aggregation and module-integrated electronics, streamlining permitting and interconnection processes to reduce project 'dropouts', and adopting high-volume lean manufacturing and component standardization.","ai_generated":true,"unit":"rmi-001024#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Balance of system (BoS) costs, which include all up-front costs except the PV module, represent approximately 50% of the installed cost for commercial and utility PV systems.","ai_generated":true,"unit":"rmi-001024#insight-1","date_modified":"2026-10-23"},{"text":"Implementing the report's recommendations could reduce total BoS costs to between $0.60 and $0.90 per watt for large rooftop and ground-mounted systems, representing an improvement of about 50% over current best practices.","ai_generated":true,"unit":"rmi-001024#insight-2","date_modified":"2026-10-23"},{"text":"Structural costs can be significantly reduced by minimizing wind forces; for ground-mounted systems, a 30–35% reduction in wind forces is achievable through strategies like staggering arrays and using border fencing.","ai_generated":true,"unit":"rmi-001024#insight-3","date_modified":"2026-10-23"},{"text":"Electrical system costs could be reduced by 75–90% through new technology approaches, such as module-integrated power electronics and high-voltage aggregation (switching from 600 V to 1,000 V).","ai_generated":true,"unit":"rmi-001024#insight-4","date_modified":"2026-10-23"},{"text":"Business process costs, which account for over 10% of total project costs (approximately $0.39/watt), are driven by high project 'dropout' rates and inefficient, non-standardized permitting and interconnection processes.","ai_generated":true,"unit":"rmi-001024#insight-5","date_modified":"2026-10-23"},{"text":"The report proposes the creation of a National Solar Site Registry (NSSR) to compile data on insolation, grid capacity, and jurisdictional regulations to reduce project dropouts and improve site assessment.","ai_generated":true,"unit":"rmi-001024#insight-6","date_modified":"2026-10-23"},{"text":"Transitioning from 'craft' to high-volume lean manufacturing and increasing component standardization could reduce some BoS component costs by up to 30% in the short term.","ai_generated":true,"unit":"rmi-001024#insight-7","date_modified":"2026-10-23"},{"text":"Current structural codes, specifically ASCE-7, are identified as a barrier because they do not account for the shielding effects of fences or other structures, leading to overly conservative and expensive designs.","ai_generated":true,"unit":"rmi-001024#insight-8","date_modified":"2026-10-23"}],"climate_tags":["photovoltaics"],"geography_discussed":[],"frame_perspective":[],"analysis_type":["cost analysis","technical design review","process optimization"]}]}
