App Features

More than just a calculator...
Your smart engineering assistant

Discover the professional tools the Solar Calculator app puts in your hands to design accurate and safe systems in seconds.

Smart Device Scanning (OCR)

Use your phone's camera to scan appliance labels, and the app will automatically extract power consumption (Watts) or calculate Volts and Amps to ensure flawless accuracy.

Hydraulic Pump Calculator

An advanced engineering engine that calculates friction loss and Total Dynamic Head (TDH), guiding you to the optimal pump and inverter size for your agricultural project.

Integrated Site Tools

The app provides a built-in compass to determine panel tilt, GPS for location, and a smart cable sizing tool (DC/AC) to prevent voltage drop.

Professional Engineering Reports

After completing your calculations, generate a PDF report containing all engineering details and share it instantly with your clients or team via WhatsApp or email.

Sudan-Specific Irradiance Data

A built-in database for 25+ Sudanese cities with real Peak Sun Hours (PSH) for each region, so your results are realistic, not just estimates.

Works Offline

Every calculation runs on your phone, so you can use the app in the field or in areas without a network — and your projects stay saved until you're back online.

Exclusive Features

Why the Solar Calculator App?

Frequently Asked Questions about the Solar Calculator App

Is the app only for homes or also for large projects?
The app is comprehensive and designed to serve all needs. It includes tools to evaluate off-grid and hybrid systems for homes and businesses, plus a specialized, precise hydraulic calculator for agricultural water pumping projects.
How does the app handle variations in solar irradiance between cities?
The app features a built-in geographic database. Once you select your city, the system fetches the exact Peak Sun Hours (PSH) for that region, ensuring fully realistic calculations rather than mere approximations.
Can I adjust loss factors or change battery types?
Absolutely. The app gives you deep control (Preferences) to adjust loss factors, set inverter safety margins, and choose battery types (like Lithium or Lead-Acid) while automatically calculating the specific Depth of Discharge (DoD) for each type.
How do I benefit from the built-in 'Cable Calculator' tool?
The cable calculator helps technicians and engineers on-site determine the required wire gauge based on voltage, current, and wire length. This ensures system safety, prevents cable overheating, and avoids voltage drop.
Does the app work without an internet connection?
Yes. All calculations run right on your phone, and the solar irradiance data for Sudanese cities is stored inside the app itself. You only need internet to download or update the app, or to share a PDF report.
Is the app free? Is it available for iPhone?
The app is completely free with no ads, available for Android 6.0 and up on the Google Play Store. iPhone and desktop users can use the web version directly from their browser.
