A PV array produces 10 kW at 25°C. At 50°C with a coefficient of -0.45%/°C, what is the output?
A PV module shows burn marks near the junction box. What is the most likely cause?
A PV system is installed in a location with an average annual ambient temperature of 30°C. If the module's NOCT (Nominal Operating Cell Temperature) is 45°C, what is the expected cell temperature under standard operating conditions (800 W/m² irradiance)?
The following dc portion of a PV schematic (functionally grounded conductor not shown) is submitted to the building official for permit approval. The building official, who also is he AHJ, allow the system to be installed by requiring what NEC-required MINIMUM size equipment grounding conductor at Location A?
A PV connection is being made at the center of a 300 ft. long 200 feeder. See the attack diagram. The feeder originates in the upper third of the 800A main service panel (800A main breaker) with a 200A breaker and terminates in a 200A main-lug-only subpanel. The rated output of the PV system inverter is 100A.
Which are the NIMUMUM actions required to achieve an NEC-compliant installation?
