PV System Calculator – Fast, Smart, and Professional Solar PV Design

Take your solar projects to the next level with PV System Calculator, the ultimate tool for engineers, students, solar enthusiasts, and anyone planning an off-grid or grid-tied PV system. Designed for speed, accuracy, and simplicity, this app makes PV system sizing fast, reliable, and stress-free.

Instant, Accurate PV Calculations

Plan your solar system with confidence. Just input:

• Daily energy demand (kWh/day)
• Peak sun hours for your location
• Battery efficiency and Depth of Discharge (DOD)
• Days of autonomy and battery voltage
• PV panel specifications and module short-circuit current (Isc)
• Peak loads

The app instantly calculates all essential system parameters:

• Required PV power
• Number of solar panels
• Battery capacity
• Inverter size
• Charge controller ratings

No guesswork—only clear, actionable results for home, off-grid, or large-scale solar projects.

Why Users Love It

• ⚡ Fast and accurate: Professional-grade calculations in seconds
• 🔧 All-in-one solution: Size PV arrays, batteries, inverters, and charge controllers
• 🌐 Offline-ready: Works anywhere, no internet required
• 🎨 User-friendly interface: Clean, modern, and intuitive design
• 📏 Flexible for any project: From small rooftops to large commercial PV plants

Who Can Benefit
• Engineers & Technicians: Save time and reduce manual errors
• Students: Learn solar system design principles with hands-on examples
• Solar enthusiasts & DIY users: Plan and optimize home PV setups efficiently
• Off-grid planners: Ensure reliable power in remote areas
Use Cases for Every Solar Project
• Residential rooftops: Design and optimize home solar systems
• Remote/off-grid installations: Ensure dependable power for cabins, farms, or rural areas
