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

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

Plan your solar PV system with confidence. Simply input:

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

The app instantly calculates all essential system parameters:

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

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

Why Users Love It

• Fast and precise: Get professional-grade calculations in seconds.
• All-in-one solution: PV array, batteries, inverter, and charge controller sizing.
• Offline-ready: Works anywhere, no internet required.
• User-friendly interface: Clean, modern design with easy navigation.
• Flexible for any project size: From small rooftop systems to large commercial PV plants.
• Non-intrusive ads: Designed for a smooth user experience.
Who Can Benefit
• Engineers & technicians: Save time and reduce manual errors.
• Students: Learn solar system design principles with practical examples.
• Solar enthusiasts & DIY users: Plan and optimize home solar 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.
• Commercial PV plants: Estimate large-scale system requirements with accuracy.
• System optimization: Calculate DC/AC ratios, inverter sizing, and charge controller selection.

Why It Stands Out

Unlike other solar calculators, Solar PV System Calculator delivers complete system sizing in one app — no extra software required. Its offline functionality, fast calculations, and intuitive interface make it perfect for field work and project planning.
