Residential and Small Commercial Solar Photovoltaic and Storage Permitting, Inspection, and Interconnection Timelines: A Retrospective Review (2017-2023)

This report is part of the ongoing Solar Time-Based Residential Analytics and Cycle Time Estimator (SolarTRACE) project, led by the National Renewable Energy Laboratory (NREL). The SolarTRACE project utilizes time-stamped project-level data provided by installer-partners to assess nationwide and AHJ- and utility-level PI&I and other solar PV adoption timelines since 2017. Our dataset now covers 22% of residential solar and 33% of residential storage installs in the U.S. since 2017. This report provides an update to our previous 2022 report (Cruce et al., 2022b) and includes: updated 2017 2023 project timelines for residential rooftop solar PV up to 20kW; updated tracking of permitting process changes at nearly 4,000 AHJs nationwide; and first-ever reporting of timelines for residential PV+storage projects up to 20kW.

Limits on Interconnection Bandwidth for On-Board Processing

This viewgraph presentation reviews the constraints, and concerns of spacecraft design, in particular spacecraft instrumentation design and the issues concerning space communication. The advantages and disadvantages of several communication options are reviewed. Ultimately there will be spacecraft communication not between boxes on spacecraft, but between spacecraft. The future of spacecraft communication is interplanetary networks.
