SolarCalc Pro turns your iPhone into a complete off-grid solar design toolkit for installers, PV designers, and renewable energy enthusiasts who can't rely on cell signal in remote builds. Get accurate solar panel sizing, battery bank configuration, daily load estimation, inverter sizing, charge controller selection, and cable gauge calculations — all in one app, 100% offline. Designed for solar professionals, electrical engineers, and DIY off-grid enthusiasts who need fast, reliable calculations in the field or at the desk. Every calculation runs on-device with zero connectivity required. SOLAR CALCULATORS: • Solar Panel Calculator — Calculate the exact number of panels and total wattage needed for your off-grid system. Factor in location, sun hours, system losses, and panel specifications to get precise sizing recommendations. • Battery Bank Calculator — Design your battery bank with confidence. Calculate total capacity (Ah/kWh), determine series/parallel configuration, and account for depth of discharge (DoD) for lead-acid, AGM, gel, and lithium batteries. • Daily Load Calculator — Estimate your total daily energy consumption in watt-hours. Add appliances with their wattage and daily usage hours to build a comprehensive load profile for accurate system sizing. • Inverter Sizing Calculator — Size your inverter based on total load, surge requirements, and system voltage. Supports 12V, 24V, and 48V configurations with proper safety margins and efficiency factors. • Charge Controller Calculator — Determine the right charge controller amperage and type (PWM vs MPPT). Calculates based on panel array voltage, current, and battery bank specifications. • Cable Sizing Calculator — Calculate proper cable gauge (AWG/mm²) for DC and AC runs. Accounts for voltage drop, current capacity, cable length, and temperature derating to ensure safe, efficient wiring. REFERENCE GUIDES: • Solar Panel Specifications — Quick reference for common panel wattages, voltages, and current ratings. Monocrystalline, polycrystalline, and thin-film comparison data. • Battery Technology Guide — Compare lead-acid, AGM, gel, and lithium-ion (LiFePO4) batteries. Cycle life, DoD limits, temperature performance, and cost per kWh. • Wire Gauge Reference — AWG to mm² conversion tables, ampacity charts, and voltage drop percentages for standard cable sizes used in solar installations. BUILT FOR THE FIELD: • Calculation History — Recent calculations saved automatically. Review and compare past results across different projects and system designs. • Unit Toggle — Switch between Imperial (US) and Metric (SI) units with one tap. Watts, amps, volts, AWG/mm², feet/meters. • Dark Mode — Full dark/light mode support for any environment. • 100% Offline — No internet required. Every calculation and reference runs entirely on-device. Use it on the rooftop, at the job site, or at your desk. WHO IS THIS FOR: • Solar Installers & PV System Designers • Electrical Engineers & Contractors • Off-Grid & Tiny Home Enthusiasts • RV & Van Life Solar DIYers • Renewable Energy Students & Educators • Homestead & Cabin Owners • Marine & Boat Solar Installers • Emergency Preparedness Planners Built for solar professionals and enthusiasts by people who understand the industry. SolarCalc Pro uses industry-standard formulas and calculation methods — not guesswork. From beginner to senior engineer, this is the off-grid solar calculator that belongs in your pocket.
