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?
An installer is using ½ in lag boits to secure roof-monitoring hardware to rafters through a roof deck. Which of the following should the installer predrill?
When doing initial inspections on a PV system that was installed using racking that is not compliant with UL.2703, an inspector should pay special attention to which electrical attribute?
An installer is hired to troubleshoot a 10-year-old roottop system with open-circuit voltage of 300V. The ground-fault detection (GFD) device has tripped. The insulation on the exposed source circuit cables has deterlorated with multiple cracks and has no flexibility. Which concern is the MOST likely safely issue when servicing this array?
A PV module has a NOCT of 47°C. At 1000 W/m² and 35°C ambient, what is the cell temperature?
Which of the following should a PV installer do during dc insulation resistance testing?
Which electrical connection requires the use of a torque device to complete the connection per NEC requirements?
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?
A site survey indicates a residential roof with a 4:12 pitch facing 20° east of south. The local latitude is 35°N, and the optimal tilt for maximum annual production is equal to latitude. What adjustment should be made to compensate for the roof’s orientation and tilt to achieve near-optimal output?
