What's New in Solar Energy Forecast

1.2.1

August 26, 2026

Added a new “Forecast and History” screen: you can now view solar potential, cloud cover, radiation, and solar system generation across an extended range of past and future days. On the main screen, today’s forecast now shows how much energy the system may still generate before the end of the day, along with the forecast for the whole day.

User reviews

Highly recommended

If there was a setting to account for shading that adjusts with the season etc. it would be more accurate. The only way now to do it is to adjust for losses.
I like the simple interface and it gives me a pretty accurate prediction for my system.

So far so good

Great app. Not sure why it doesn’t add the solar arrays together?

Response from developer

Thank you for your feedback! We’re sorry the review prompt appeared too soon. We’ll take a look at its timing and make it less intrusive in future updates. Thanks for letting us know!

Neat App

Having solar panels it is always good to know what kind of conditions we might expect. This app is incredibly easy to use and understand and actively reflects the weather. It helps me to plan when to make good use of the energy I have stored and when not to.
I’ve had the app for quite some time and I use it everyday on my phone and IPad. It’s so useful I hope they develop a Mac version soon.

Highly recommended.

Thank you so much for your kind review and recommendation! We’re very glad that you find the app useful and easy to use. Thank you for your support! ☀️

Great App

Very simple to use and setup and has all the functionality of other paid apps - great app

Not great

The predictions are all over the place and often seem completely disconnected from the actual weather forecast. I can check the BOM well in advance and see conditions that clearly don’t match what the app is predicting.

Even on a fully overcast day, the app can still predict around 65kWh of generation, when in reality we’re nowhere near even 15kWh. That makes the predictions pretty useless for planning battery usage.

It would also be really useful if the app allowed users to enter their actual generation at the end of each day. Surely feeding real-world data back into the system would help improve its future predictions.

At the moment, I just don’t find the predictions reliable enough to be useful.
