Commercial Rooftop Solar Design
Budget: $10 – $20 SGD
I’m looking for a solar engineer who can prepare a straightforward yet accurate design for a commercial rooftop installation. My goal is to walk away with a practical blueprint that lets me understand system sizing, component placement, and expected production before I move on to permitting and procurement.
Scope
• Produce a preliminary array layout for a commercial roof (include tilt, azimuth, and spacing).
• Run a quick shading and energy-yield analysis using a standard tool such as PV*Sol, Helioscope, or PVsyst—whatever you’re most comfortable with.
• Provide an outline bill of materials: panels, inverters, racking, and balance-of-system components.
• Summarize key assumptions (roof dimensions, irradiance data source, loss factors).
Flexibility on panel technology is fine; just note which option—mono, poly, or thin-film—you select and why.
Please keep the file set lean: a PDF report and the native design file are all I need for this initial phase.
