VoltSize
Solar Panel & Battery Sizing
Free · Designed for iPad. Not verified for macOS.
Panel, battery, inverter & cable sizing; Home/Caravan/Boat wizards; real panel tilt measurement with camera + compass — all in one app.
VoltSize is a complete calculation and planning toolkit for anyone building a solar power system.
CALCULATORS
- Panel Sizing: how many watts of panels you need based on your daily consumption
- Battery Capacity: compare LiFePO4, AGM, Gel and other battery types
- Inverter Sizing: find the right inverter power with a safety margin
- Cable Gauge: pick the right wire thickness based on voltage drop
- Daily Consumption: pick from a ready device library to total your Wh/day
WIZARDS
Step-by-step guided wizards for Home, Caravan and Boat setups: pick your system voltage and battery type, add your devices, enter your sun hours, see results instantly.
PANEL ANGLE & DIRECTION
Pick your location on the map or use GPS; VoltSize suggests the optimal panel tilt angle and direction. Then use your phone's camera and compass to measure the panel's real angle and direction live.
SHARE
Export your wizard results or device list as a PDF and share it via WhatsApp, email, or any app you choose.
All data stays on your device. Calculations in VoltSize are estimates; always consult a licensed electrician or solar installer before any real installation.
