What's New in Sizer App
4.1
September 15, 2026
### What’s New in This Version We’ve made solar system sizing even easier! **Solar Panel Sizing** You can now enter your total energy usage in Wh (watt-hours) to calculate the total solar panel capacity required. Tap the calculated solar panel capacity, enter the wattage of each panel (e.g., 450W or 550W), and the app will automatically tell you the number of solar panels you need. **Battery + Home Energy Calculation** You can now enter your battery capacity in Wh together with your home’s total energy usage. The app will calculate the solar panel capacity required to both fully charge your battery and supply your home’s energy needs. Smarter calculations. Better system sizing. Easier solar planning.
