One of the more recent trends from the past decade of photovoltaic adoption is the ability to connect directly into the power grid. In such cases, policies have been adopted to allow renewable generators to "bank" excess power into the grid and receive credits for the excess energy (in kWh). But each locale will be subject to different policies enabling or prohibiting such practices. Net metering is expanding in creative ways, including aggregation of multiple distributed energy sources for credit, and distributing joint credit from a centralized solar garden [4] among multiple participants in a community.
Permitting is the unseen monster of project development that will slow or stop a project from moving forward. The key rewards of an established permitting process for SECS include reduced costs of installation and faster turnaround from design to deployment. It will be well worth your integrative design team's time to familiarize yourselves with the permitting process for your locale of interest.
Best practices have been itemized by IREC in our reading. We can distill those into a few core features that we would hope for in an integrative process that includes permitting:
