What's New in Sun Hours for Solar Panels

2.1.5

November 4, 2026

Hi all, there are some back-end weather model improvements in this version. Thanks for sticking with me. Improving accuracy is my number 1 focus and I have paused new features until we can get the weather model accuracy in a better place. Its the app's first year and it is constantly learning from the seasons as we go on. If you decide to share your data (always optional and deletable) it does massively improve the accuracy as the app applies a seasonal fix to your model :)
