Permit-Ready Solar Design, Engineering & Interconnection
Engineering-driven PV and storage system designs, permitting, and utility interconnection support developed for constructability, compliance, and long-term performance.
Successful solar and storage projects begin with accurate designs and are completed through disciplined permitting and interconnection processes.
P&S EcoSolutions provides in-house PV design and engineering services combined with permitting and utility interconnection support.
Our team manages the technical front end of each project, designing systems that can be built, permitted, inspected, and interconnected efficiently while aligning directly with the installation team.
Where required, stamped engineering is provided through licensed professional engineers.

Site Assessment & Field Verification
Each project begins with a comprehensive on-site survey to capture accurate field conditions before design.
Our team measures roof dimensions; verifies structural and roofing conditions; documents obstructions and shading; conducts drone imagery where applicable; and evaluates electrical service equipment, including main service panels and meter locations. This field-verified data ensures all designs are based on real-site conditions, reducing revisions, preventing constructability issues, and supporting faster permitting and installation.
