## What is SolRad4Me?

How much sunshine did your yard actually get? SolRad4Me tells you.

SolRad4Me reports the solar energy (in kWh/m²) that reached any location over any date range, using trusted NASA POWER satellite and meteorological data. Look up your home, your garden, your solar panel site, or your vacation spot, then compare one period against another.

Wondering how this September compares to September four years ago? Curious whether last summer was sunnier than the one before? Planning a solar installation, or tracking the growing season for your garden? SolRad4Me gives you the numbers.

LOOK UP SUNSHINE
• Pick a saved address or enter latitude and longitude
• Choose any start and end date
• Date pickers adjust automatically so your range never gets backward
• See total solar energy for the period, with missing days clearly reported

SAVE AND COMPARE
• Save any result to review later
• Drag to reorder your saved lookups in the order that matters to you
• Browse a clean list and detail view on iPhone and iPad
• Compare periods side by side, such as Sep 2026 vs. Sep 2022

MANAGE ADDRESSES
• Save named addresses like Home, Cabin, or Solar Farm
• Set a default address for fast lookups
• Addresses are located once when you add them, so lookups are quick
• Optional support for non-US addresses, with a country picker and flexible region and postal code fields

BUILT FOR iOS 26
• Designed with SwiftUI and Liquid Glass
• Built-in Help tab explaining every feature
• Utilities tab for bulk cleanup of saved lookups and addresses
• Your data is stored on your device

ABOUT THE DATA
Solar values come from NASA's POWER (Prediction Of Worldwide Energy Resources) project, specifically the all-sky surface shortwave downward irradiance measurement. NASA POWER data lags real time by a few days, so the most recent days may be reported as missing.

SolRad4Me is not affiliated with or endorsed by NASA.

Whether you're a solar enthusiast, gardener, homeowner, student, or just curious about the sun, SolRad4Me puts years of sunshine data at your fingertips.
