| Summary/Abstract |
Local permitting can ensure the safe installation and operation of rooftop solar photovoltaic (PV) systems. At the same time, burdensome local permitting processes and local variation in requirements may pose challenges to PV deployment. In this article, we explore new data on the durations between key steps in the PV permitting process in the United States. The data suggest that a typical customer can expect to wait around 25–100 days from permit application until an installed system passes inspection. Permit durations vary significantly across jurisdictions, due in part to differences in local permitting policies. However, permit durations vary as significantly within jurisdictions as across them, in part due to significant variation across installers, suggesting that installer strategies and practices play an important role in permitting timelines. Permit durations have declined over time, reflecting progress from permit streamlining policies and jurisdiction learning-by-doing, though durations have stabilized in recent years. The data suggest that typical PV customers still face long and uncertain permitting timelines in the United States.

| Summary/Abstract |
Hawaii's 100% Renewable Portfolio Standard target has led to rapid growth in renewable generation resources. This has resulted in grid issues given the islanded nature of Hawaii's grid. The state has decided to use battery storage in its grid to address these issues. This motivates us to try to understand the various business models in the state and the minimum set of barriers that must be overcome for its successful deployment. We achieve the former by assessing the projects in the state and identifying the dominant business models. For the latter, we use a barrier-solution framework that posits the minimum set of barriers that must be met for the successful deployment of battery storage business models and we verify it by identifying the role of various policies/drivers in supporting these business models. As a result, we find predominantly three business models in Hawaii: Co-located Front-of-the-Meter, Behind-the-Meter, and Aggregated Behind-the-meter. We also verify that at least one barrier from barrier categories associated with market demand and project economics along with all the barriers related to interconnection and market participation must be addressed for successful deployment of battery storage. Based on these findings, we give recommendations to policymakers seeking to develop a battery storage market.
