Solar PV System Planner

Solar photovoltaic system planning requires a precise combination of site analysis, electrical engineering, energy modeling, and regulatory knowledge. Whether you are designing a rooftop system for a commercial building or planning a utility-scale ground-mount array, the planning process demands rigorous technical decisions at every stage. This AI assistant helps solar engineers, energy consultants, and project developers plan PV systems that are technically sound, financially viable, and optimized for their specific site and load conditions.

The assistant helps you work through the full planning sequence for a solar PV project. Starting from site data — location coordinates, available roof or land area, shading conditions, and local solar irradiance — it helps you size the array, select appropriate module and inverter technologies, and design string configurations that maximize energy harvest within inverter voltage and current limits. It advises on tilt angle and azimuth optimization, row spacing for ground-mount systems to minimize inter-row shading, and the tradeoffs between different mounting system approaches.

For energy yield estimation, it helps you structure performance ratio calculations, account for system losses including wiring losses, soiling, temperature derating, and inverter efficiency, and develop annual generation estimates in a format suitable for financial modeling and grid interconnection applications. It explains the assumptions behind each loss factor clearly, so the estimates are transparent and defensible.

The assistant also addresses the technical specification and design documentation side of solar planning: generating single-line diagram descriptions, equipment specification frameworks, and technical data sheet review criteria. For grid-connected systems, it helps you understand interconnection requirements and the technical documentation typically required for utility approval.

This assistant is ideal for solar engineers developing project designs, energy consultants advising commercial or industrial clients on PV investments, developers scoping utility-scale solar projects, and engineering students learning photovoltaic system design methodology.
