A PV project’s transition from the construction phase to the operations phase is a flurry of activity. Project stakeholders must coordinate schedules, materials, trades, troubleshooting and testing while adhering to design documents, contractual requirements and project milestones. As such, the sprint to achieve commercial operations is a busy time with many challenges. We share lessons learned from our project completion experiences, both good and bad, and our recommendations for a more...

The way that utilities study distributed energy resource interconnections (DER) in California is about to change dramatically. In this article we elaborate on the distribution planning tools that stakeholders in the state are developing to streamline DER interconnections and proactively identify optimal locations for DER deployment. The days of anxiously waiting for the Rule 21 process to run its sometimes excruciatingly long course may soon become a thing of the past because of the keen...

As PV systems get larger, AHJs are more likely to require power engineering reports that are unfamiliar to some solar professionals but well known to traditional power engineers. We take an in-depth look at the types of electrical design calculations and reports that utilities and other AHJs require in large-scale PV plant applications, and the power engineering software that supports these calculations. Note that a licensed professional engineer must supervise these types of calculations to...
