Introduction
Not every solar task requires full-scale simulation software. Often, engineers and installers need fast, reliable utility tools to solve specific problems—such as conductor sizing or PV string visualization.
PVTools is a completely free utility software developed to support solar professionals, students, and enthusiasts with essential NEC-based calculations and visual tools. Utilities provided in PVTools are basically part of the major software PVBytes provided at https://electnology.com/pvbytes. These tools have been extracted and provided as separate utility for the solar community.
