Sample answers for preparation guidance only. Policy figures and subsidy values (e.g. PM Surya Ghar) are time-sensitive — verify against official sources before use. Last reviewed August 2026.
A: Pitch distance = panel length * cos(tilt) + panel length * sin(tilt) * tan(latitude + 15). This ensures module rows do not shade each other during winter solstice.
A: Transposition loss is the difference between global horizontal irradiation (GHI) and global tilted irradiation (GTI). You minimize it by optimizing panel tilt angle based on latitude and array orientation (azimuth).
A: An SLD is an electrical schematic showing the layout of string connections, DC/AC cables, string inverters, isolation breakers (DCDB/ACDB), earthing switches, net-meter, and grid ties.
Hands-on rooftop module alignments, earthing wiring, structural assembly.
Directing installation crews, wiring inverter stringing boxes, inspecting structural certifications.
Managing utility array scales (10MW+), grid substation connection compliance, BOS procurement.
