Did you know there were industry standards for sizing off-grid solar systems?
Nowadays there seems to be a standard for almost everything, and the same holds true for solar. There are actually several industry standards for solar, that vary from components (e.g. solar modules) to system design (e.g. stand-alone solar, hybrid design). I'd like to focus on a couple: IEEE 1561 "Guide for Optimizing the Performance and Life of Lead-Acid Batteries in Remote Hybrid Power Systems" and IEEE 1562 "Guide for Array and Battery Sizing in Stand-Alone Photovoltaic
