The report argues that while solar PV module costs have declined aggressively, balance of system (BoS) costs—which account for about half of total installed costs—remain a significant barrier to adoption. 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.

The document outlines the necessity of rapid solar PV growth to meet climate targets, identifying high costs as a primary barrier. It proposes a multi-dimensional approach to reduce manufacturing costs by a factor of two or more using lean manufacturing, whole systems design, and end-use efficiency. Additionally, it emphasizes the need to professionalize rooftop installation and calls for government support through stable demand and standardized regulations to avoid supply chain bottlenecks.
