WHAT WE OFFER
Our Residential Solar Design Services
Smart solar designs for modern homes—optimized for performance, savings, and sustainability.
Rooftop Solar Layout Design
We design precise, optimized rooftop solar panel layouts for single-family and multi-family homes — accounting for roof pitch, orientation, shading, setbacks, and local code requirements. Every layout is engineered for maximum energy production and delivered permit-ready.
Solar PV System Design
Our engineers design complete residential solar PV systems — including panel selection, string sizing, inverter configuration, and energy production estimates — tailored to each homeowner's energy needs and roof structure.
CAD Drawings and Schematics
We produce professional residential solar CAD drawings including 2D layout plans, electrical single-line diagrams, racking and mounting detail drawings, and all supporting documentation required for permit submission.
AHJ-Ready Permit Plan Sets
Every residential permit package we produce is tailored to meet the exact requirements of your local Authority Having Jurisdiction — designed for first-submission approval. Fire safety plans and structural details included.
As-Built Drawings
Post-installation as-built documentation reflecting actual field conditions — required by most AHJs before issuing the Permit to Operate.
High-Efficiency Residential Solar Layouts
We create smart solar layouts that maximize rooftop space for optimal energy output and reliable performance. Our designs consider roof orientation and shading to ensure consistent efficiency, helping you achieve better savings and long-term value.
