Suggested Practices

The recommended installation practices contained in this guide progress from the photovoltaic modules to the electrical outlets. For each component, NEC requirements are addressed, and the appropriate Code sections are referenced in brackets. Certain electrical information must appear on each module. The information on the factory-installed label will include the following items: • Polarity of output terminals or leads • Maximum series fuse for module protection • Rated open-circuit voltage • Rated operating voltage • Rated operating current • Rated short-circuit current • Rated maximum power • Maximum permissible system voltage [690-51].
