Solar PV Design Engineer at RIH Engineering designing commercial and industrial PV systems with HelioScope and NEC-compliant AutoCAD SLDs.

India
Message

At RIH Engineering, I design commercial and industrial solar PV systems in HelioScope, covering array layouts, stringing, inverter selection, and production and loss analysis. I also assess baseload and load profiles to size systems against site consumption and support feasibility assessments.

I prepare AutoCAD single line diagrams and electrical layouts to NEC requirements, along with string sizing, conductor, voltage drop, and protection calculations. My work includes preliminary site screening and technical documentation such as design reports and BOMs.

Before RIH Engineering, I prepared HV and LV electrical drawings at Advantech MEP Consultants & Engineers. I also used AutoCAD Electrical and EPLAN for circuit analysis, component selection, schematics, panel layouts, and automated BOMs.
