Description
Residential Hybrid PV System Design Toolkit
A practical engineering toolkit developed to support solar PV engineers, electrical engineers, designers, consultants, and engineering students in the design of residential hybrid PV systems.
This package combines a professional Excel-based design calculator, complete AutoCAD project drawings, and the technical reference documents used throughout the practical design example.
WHAT’S INCLUDED?
1. Hybrid PV System Design Calculator – Excel
A structured engineering calculator covering the main stages of residential hybrid PV system design, including:
• Project Data Collection
• Residential Load Analysis
• PV System Sizing
• Inverter Sizing & Selection
• Battery Sizing
• PV String Sizing & Verification
• PV DC Cable Sizing & Voltage Drop
• Battery DC Cable Sizing & Voltage Drop
• AC Cable Sizing & Voltage Drop
• Automatic PASS/FAIL design verification checks
The Excel tool is organized into sequential design sheets with clearly identified user inputs, calculated results, and fixed/reference data to provide a structured engineering design workflow.
2. Residential Hybrid PV Project – AutoCAD Drawings
A practical AutoCAD drawing package developed for the residential hybrid PV system design example.
The project drawings include:
• Site Layout
• PV String Layout & Distribution
• Single Line Diagram (SLD)
The AutoCAD drawings complement the Excel Design Calculator and demonstrate how the calculated system design is translated into practical engineering drawings.
3. Equipment Datasheets & Technical Manuals
The package includes the relevant equipment datasheets and technical manuals used throughout the design example.
These documents provide the technical parameters required for the design calculations and equipment verification, including data related to:
• PV Modules
• Hybrid Inverter
• Battery System
• Electrical and system components used in the project
The included documentation allows users to follow the design process, understand the source of the technical input data, and verify the parameters used throughout the Excel calculator and project drawings.
4. Cable Sizing & Technical Reference Documents
Supporting cable data, reference tables, and technical documents used for cable sizing, current-carrying capacity, voltage-drop calculations, and related electrical design checks are also included.
This provides a practical connection between the reference data and the engineering calculations performed within the toolkit.
WHO IS THIS TOOLKIT FOR?
This toolkit is designed for:
• Solar PV Engineers
• Electrical Engineers
• PV System Designers
• Renewable Energy Professionals
• Engineering Consultants
• Engineering Students
• Anyone developing practical skills in residential hybrid PV system design
WHY THIS TOOLKIT?
Rather than providing calculations alone, this toolkit connects the main stages of a practical hybrid PV design workflow:
Engineering Calculations → Equipment Selection → String Design → Cable Sizing → Design Verification → AutoCAD Project Drawings
It provides a structured practical example that can be used to better understand how the different stages of residential hybrid PV system design are connected.
LANGUAGE
The Excel Design Calculator, AutoCAD project drawings, and engineering content are provided in English.
IMPORTANT NOTE
This toolkit is intended as an engineering design aid and educational/professional reference.
Calculation results depend on the accuracy of the entered project data, design assumptions, selected equipment, and technical inputs.
Final system design, equipment selection, cable sizing, protection requirements, and other engineering decisions shall always be verified against the applicable manufacturers’ datasheets, technical manuals, standards, local regulations, and project-specific requirements.
