Solar Setup: Off-Grid Calc
By Ammar Khatib
Solar Setup: Off-Grid Calc is a utility app for iOS and Android that automates solar panel, battery, and inverter sizing for off-grid power systems.
The App DNA
What makes this app unique?
The application removes the cognitive cost of manual electrical math and spreadsheet modeling, allowing users to design reliable systems without professional installer sales calls.
For Off-grid enthusiasts, van-life travelers, and tiny-house owners planning independent solar power systems.
What does it look like?
Key features
Fetches satellite-based solar irradiance data for specific locations to calculate panel requirements.
Calculates bank capacity based on depth-of-discharge limits and round-trip efficiency for lithium versus lead-acid chemistries.
Generates a professional summary of the sized solar system for installers or project documentation.
How much does it cost?
The one-time $6.99 payment model avoids subscription fatigue, directly appealing to the DIY off-grid audience.
