It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.
Photo by Owen Roberts, NREL Considerations for energy storage system testing include the following. If cost-justified by a large purchase, consider qualification testing of battery systems. Include test conditions in specifications for battery O&M diagnostics and testing.
Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).
PV systems should be designed and installed with such possibilities in mind, and measures should have been incorporated such as two-column racks (rather than post-strut), thick or non-glass covers, rigid backsheets, and through-bolted clamps. The designer should specify PV modules with high ratings for both uplift and down-force pressure.
PPE often encountered in PV system maintenance includes the following (which is not all-inclusive and depends on particular circumstances): General: Most sites will require at all times a helmet, safety glasses, safety vest, and work boots (steel-toed preferred).
