PV 302: Intermediate Photovoltaic Design and Installation

Once you have successfully completed your Basic Photovoltaics Class, you’ll be ready to dive deeper into system design. This three day course encompasses lecture, practicum design examples and hands-on lab work. You’ll focus on how to size major components for both battery based and utility-interactive PV systems. By the end of this class you should be able to demonstrate how to size PV system components, including wiring and overcurrent protection; assemble different mounting systems; and wire appropriate strings of modules. This class is ISP Accredited and counts toward the NABCEP educational requirement. More information about NABCEP certification can be found on the NABCEP website.

Prerequisite: Participants must have completed the AltE Basic PV and Site Assessment (PV 301) class in order to enroll. We do our best to ensure we offer the most complete education we can, and we realize in some cases, you have already begun your RE training. If you have a certificate of completion of a five or six day course from an ISP accredited program or NABCEP Approved Provider or if you have passed the NABCEP Entry Level Certification of Knowledge Exam, please provide your certificate and we can accept that as the prerequisite for our PV 301/302 class. Or if you have at least two years of design and installation of PV or solar thermal systems, please send us documentation and we can count that toward your prerequisite as well.

Students who complete both PV 301 and PV 302 are able to take the NABCEP Entry Level "Certificate of Knowledge" Exam at the end of the week. The cost of the test is $100 and is additional to class tuition. Please sign up for the exam prior to the start date of the class by letting a representative know at the time your register over the phone or adding a note when you register online.
