Solar Design, Personally Handled.
Gemini Solar Design is an independent PV and energy-storage design practice built around direct technical work, responsive communication, and permit-ready drawings that make sense in the field.
Sanjay Mallipudi
After earning a B.S. in Civil Engineering from Purdue University, Sanjay moved into photovoltaic system design and founded Gemini Solar Design in 2015. Clients work directly with the person developing the drawings, reviewing the electrical architecture, responding to AHJ comments, and coordinating the technical details of the project.
What Gemini Solar Design Works On
From routine residential permitting to complicated storage and commercial electrical systems,
the focus is on technically sound drawings rather than one-size-fits-all drafting.
Residential PV
Roof mount, ground mount, service upgrades, interconnection, site plans, equipment layouts, and permit documentation.
Battery / ESS & Backup
AC- and DC-coupled storage, PCS, whole-home backup, hybrid inverters, generators, and complex system integration.
Off-Grid Systems
Standalone power systems with battery banks, hybrid inverters, generator integration, rapid shutdown, and load architecture.
Commercial PV
String-inverter systems, 480V distribution, carports, feeder sizing, voltage drop, conductor schedules, and line-side interconnection.
Why the Direct-Designer Model Matters
Solar design gets much easier when the person answering your question is also the person who understands the drawing. Gemini is structured to keep that technical loop short.
How Projects Move Forward
You can start with a quick inquiry or, if you already have the project information assembled, go directly to the complete design request form.
Send the Project
Share the basic scope or submit the full project intake if you already have the equipment and site information ready.
Technical Review
The system configuration, service conditions, equipment, permitting requirements, and missing information are reviewed before design progresses.
Permit-Ready Drawings
The finished package is developed for permitting, with revisions and engineering coordination handled as the project requires.
