Technical Interview Questions
Review typical screening questions solar recruiters ask during technical interviews. Select a discipline below:
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.
Q: How do you calculate pitch distance for a fixed-tilt rooftop solar PV array?
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.
Q: What is transposition loss in PVsyst and how do you reduce it?
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).
Q: What is a Single Line Diagram (SLD) and what are its key components in rooftop solar?
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.
