Engineering Expertise & Technical Scope
Comprehensive solar engineering lifecycle delivered by Er. Dhramveer Joshi — from MW-scale utility project conceptualization to precision residential auditing.
End-to-end design of utility-scale solar PV power plants ranging from 3 MW to 8.48 MW, including comprehensive Single Line Diagrams (SLDs), DC/AC cable sizing, trench cross-sections, and integrated earthing/LPS systems.
Preparing rigorous Design Basis Reports (DBR), equipment technical datasheets, and value-engineered Bill of Quantities (BOQ) / Balance of System (BOS) optimization to achieve the lowest Levelized Cost of Electricity (LCOE).
Developing millimeter-precise AutoCAD execution drawings including module layouts, DC cable routing plans, inverter station architecture, string mapping tables, and civil-structural foundations.
Direct site execution supervision, QA/QC audits, inverter placement review, civil-electrical coordination, and active resolution of design vs site execution conflicts during construction.
Technical Skills & Engineering Disciplines
The core engineering competencies applied to scrutinize contractor quotes and audit rooftop solar plants across India.
Solar SLD Preparation
Single Line Diagrams from string level to pooling substation with protection coordination.
Cable Sizing & Routing
DC/AC cable sizing complying with IEEE/IS standards, voltage drop < 1.5%, and trench engineering.
