To help you navigate this important phase, we've compiled a comprehensive solar panel inspection checklist. Understanding and doing them properly leads to happier clients and a healthier bottom line for solar companies. Not only must you execute these inspections with precision, but you must also. . Measure and record maximum power point current (Imp) for each string. (Current measurements for each string should be within a 0. If a string is outside the range, check for shading or. . The inspection process is usually with an official that works for the local AHJ's building department, and someone that works for the utility, it can also be done by a third-party working on behalf of the AHJ or utility. This step—overseen by the local Authority Having Jurisdiction (AHJ)—ensures that the installation aligns with the approved plan set and complies with all safety codes. But visiting the solar PV manufacturer on-site can be challenging, especially if these are located. .
