A PV system includes a 600V DC disconnect with a fault current rating of 10 kA. The available fault current from the inverter is 12 kA. What must be done to comply with NEC 110.10?

A project is using a PV module with a 25-38dc maximum power voltage range and a single input inverter with an operating windows of 250vdc-450dc. The dwelling the system is to be installed on has a 5:12 roof with a southeastem face that can accommodate 14 modules and southwestern face that can accommodate 10 modules. What is the MAXIMUM number of modules that can be installed for proper inverter maximum power point tracking?

A 1. 100 ft, 2 ranch home with cathedral callings has a 14 ft. x 41 ft. 8 in , south-facing , composite shingle roof. An engineer has determined that the home’s 2 in, x 6 in. on-center roof rafters are strong enough to gold a solar electric system. The system will have 62.25 in. x 32.50 in. modules with a 1-in gap between modules and a standard twin-rill mounting system number of modules that can fit on the roof on under these conditions?

A PV system is located at 41 N latitude. The sun angle is 23 on December 21 at solar noon. Assuming that the 65 ft tree is directly south of the PV array and will grow 20 ft. over the life of the PV system, what is the MNIMUM distance the tree to the button of the prevent shading?

Which load path connections need to be analyzed when determining live and dead loads on a PV array system installed directly to a metal seam roof?

A module’s Voc is 40V at STC. At -5°C with a coefficient of -0.33%/°C, what is the Voc?

In the middle of a winter day, the data acquisition system for a ground-mounted PV system with large central inverters sends an email alert that system performance is at 50% based on irradiance and temperature performance calculations. No inverters are completely offline. The closed technician is a 4-hour drive from the site, and there are no cameras on site. Which is the BEST response to this situation?

A site has a known magnetic declination of 14 west. What should the corrected azimuth reading of the array be in order to be facing true south?

A grid-interactive PV system with battery backup is being installed with a ground-mounted PV array located 200 ft, from the inverter and batteries. The dc PV output circuit has overcuit has overcurrent protection rated from 30A. To reduce voltage drop between the array and batteries, the output circuit wire size was determined to be 6 AWG. The fused dc disconnect between the inverted and batteries is rated for 300A. What is the required size of the equipment grounding conductor between the metal battery case and the inverter?

Thermal imaging infrared cameras can be used to help find which of the following system operational issues?
