NABCEP PVIS study plan

Map the PVIP task list into your own checklist of site assessment, sizing, permitting, installation, commissioning, and O&M subtopics

Explain how irradiance, air mass, and tilt/orientation interact to set array energy yield

Compute a simple string sizing check (Voc temperature-corrected at record low, Vmp window at high cell temperature) for a sample 10 kW array

Identify the NEC Articles and sections most cited on the exam (690, 705, 250, 310, 480) and note what each governs

Perform a full site survey exercise: shade analysis, roof condition, structural attachment points, interconnection location, and pathway routing

Size a residential grid-tied system from an annual kWh target including derate factors and soiling

Select conductors, OCPD, and disconnects for the DC and AC sides using continuous-load and 125% rules

Draft a single-line diagram for a string inverter system with rapid shutdown

Interpret NEC 690 requirements for rapid shutdown, PV source/output circuits, and labeling

Apply NEC 705 interconnection rules for supply-side and load-side connections and calculate busbar loading

Explain grounding and bonding requirements for PV systems including equipment grounding conductors and array bonding

Describe structural and weatherproofing considerations for roof and ground mounts

Sequence a commissioning procedure: visual inspection, insulation resistance, polarity, open-circuit and operating current checks, and performance verification

Diagnose common faults (ground fault, arc fault, underperforming string, inverter derating) and state the test that isolates each

Explain storage integration basics: ESS sizing, inverter modes, and NEC 706 concepts

Practice safe work practices for DC arc hazard and energized work

Work through the permitting and interconnection workflow including utility application data and inspection readiness

Compare string, microinverter, and hybrid inverter architectures on cost, shading tolerance, and code implications

Calculate voltage drop and verify conductor ampacity derating for temperature and conduit fill

Review O&M practices including monitoring alarms, IV curve tracing, and cleaning schedules

Answer timed practice sets under exam conditions and log every missed question by root cause

Re-derive from memory the formulas for string voltage limits, voltage drop, energy yield, and conductor sizing

Review battery and energy storage safety requirements including ventilation, clearances, and disconnection

Explain the roles and limits of the PV Installation Professional in project scope and job safety analysis

Close every gap identified in the week 6 error log by reworking the underlying concept

Rehearse code lookups quickly using the index and article structure for unfamiliar questions

Complete two hands-on exercises, such as a torque and terminations drill and a megger test on a mock array

Explain inspection red flags that commonly fail a final inspection

Take two full-length timed practice exams and review every answer, right or wrong

Summarize your formula sheet and code map onto one page for final review

Confirm exam-day logistics, allowed references, and identification requirements

Rest and taper: limit study to light review in the final 48 hours
