Introduction to the Course
Details of each Chapter
Use safety nets as the sole option when working above 25 feet, since safety lines and belts are impractical, in line with OSHA.
Explore the fundamentals of electricity, including how to calculate power, voltage, current, resistance, and grounding in home electrical systems, with applications to design and installation of pv systems.
Explore direct, diffuse, and albedo radiation and how they combine into total solar irradiance. Learn how irradiance meters and direct beam detectors measure solar radiation for PV system potential.
Explore open-circuit voltage (Voc), short-circuit current (Isc), and the maximum power point (Vmp/Imp), and learn how module mismatch and series connections affect PV system performance.
Determine the maximum and minimum number of series modules to the inverter by considering the inverter dc power limit and temperature-based degradation of module performance, using vampy and bemax values.
Describe the ballasted system for PV installation, using concrete blocks (paving stones) to ballast the array, with pressure and wind-load considerations when the roof cannot bear extra weight.
Assess ventilation system types and their load bearing capacity in PV installations, ensure proper ceiling penetrations, and verify leakage with Testopel after installation.
Explore single axis and horizontal axis trackers for PV systems, illustrating sun tracking from morning to evening and how a DC motor increases production while considering cost and maintenance.
Commission PV systems by a qualified electrical professional who tests grounding continuity, polarity, voltage, and overall functionality, measures irradiance, and refrains from commissioning if parameters fall below 500.
Perform insulation resistance testing to verify the integrity of the electrical system, identify damaged components across modules, and assess wiring degradation and ground connections through circuit disconnection and testing.
This course is designed for those who are new in renewable energy, experience levels, or those who are interested to start their career in the field of solar energy. The design of this course is based on NABCEP and National Electrical Code NEC 2017. This course is also for those who want to prepare yourself for the NABCEP PV Associate Exam. This course contains 5 MCQs question at the end of each chapter and at the end, of course, there is 35 multiple Choice Questions practice exam similar to the real NABCEP Exam.
