Frequently Asked Questions

What information do you need to design a solar PV system?

Typically site location, available roof or land area, load or capacity requirements, electrical service details, and any site survey or shading data you have. I can also work from satellite imagery for preliminary layouts.

Can you design commercial and utility-scale solar projects?

Yes. I provide solar design services across residential, commercial, industrial and utility-scale systems, including ground-mounted and rooftop configurations.

Do you provide SLD drawings?

Yes. Single Line Diagrams, string diagrams and full electrical schematics are part of the standard deliverables for electrical design projects.

Can you optimize an existing solar design?

Yes. I offer design review and optimization services to identify errors, improve system performance and highlight cost-saving opportunities in existing designs.

What software do you use for solar design?

Depending on project requirements, I work with tools such as AutoCAD, PVsyst, SketchUp, Helioscope, PVcase and Google Earth for site assessment.

Do you provide PVsyst reports?

Yes. PVsyst simulation and yield analysis reports are available as part of the solar PV simulation service, including performance ratio and loss analysis.

Can you provide string sizing and cable sizing?

Yes. DC string sizing, cable sizing and voltage-drop calculations are core parts of the electrical design service.

How long does a solar design project take?

Timelines depend on system size and scope. A defined turnaround is agreed upfront during the project requirements stage, before design work begins.

Do you provide revisions?

Yes. Design review cycles are included so that layouts and drawings can be refined before final delivery.

Can you work with international clients?

Yes. I work with EPC companies, developers and installers both in India and internationally, and can coordinate remotely across time zones.
