About this app
SolarBESS Sizing Studio is the ultimate mobile and web utility engineered for solar professionals, electrical contractors, and energy entrepreneurs to streamline residential and commercial photovoltaic (PV) and battery energy storage system (BESS) projects from initial concept to final contract deployment.
Designed for maximum efficiency in the field and the office, the application guides you seamlessly through a comprehensive nine-step workflow—Project Info, Loads, Site Data, Design Preferences, Results, Bill of Quantities, Financials, Export, and Documents—transforming raw client energy data into a fully priced, print-ready proposal in minutes.
Key Features & Workflow
Precision Project Configuration: Set project parameters, client details, and target markets. Country packs automatically handle local currency rules, VAT policies, net-metering caps, and regulatory compliance notes.
Intelligent Load Profiling: Build detailed appliance lists categorized by phase, wattage, quantity, and daily runtime. Designate critical loads for targeted backup during grid outages while monitoring live summaries of daily energy and peak demand.
Advanced Site & Environmental Data: Factor in peak sun hours, tilt, orientation, shading, ambient temperature, altitude, and mounting structures to optimize panel derating and cable sizing.
Flexible Engineering Sizing Engine: Run the sizing algorithm against five independent constraints—energy autonomy, inverter limits, charge rates, and DC voltage windows. Choose between automated equipment selection (🤖 Auto-Select), browsing verified real-world products (📋 Browse Available), or custom manual inputs.
Dynamic Bills of Quantities (BOQs) & Pricing: Generate detailed itemized BOMs covering panels, inverters, batteries, cables, breakers, mounting kits, and earthing. Apply custom margins, labor fees, and design rates, or upload custom equipment catalogs and CSV price templates via bulk import.
Robust Financial Analysis: Calculate annual savings, simple payback periods, 25-year Net Present Value (NPV), Internal Rate of Return (IRR), and CO₂ offsets based on local utility tariffs, escalation rates, and your Weighted Average Cost of Capital (WACC).
Professional PDF Exports & Documentation: Export print-ready Technical Proposals, itemized BOQ estimates, and Financial Analysis reports directly to your device storage. Access built-in multilingual user manuals, terms of use, and privacy policies in English, Spanish, Portuguese, and French.
