- 📦Sun Hours for Solar Panels updated to version 2.1.5Hi 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 :)… more - ✏️Sun Hours for Solar Panels: new iPad screenshots· GB

• More accurate forecasts. Every release, we work to make your solar forecast and generation numbers more accurate, and this one takes a real step forward in how forecasts are checked against what your panels actually produce.
• Fixed a blank grey screen that some people saw after moving to a new iPhone, particularly with the phone set to Cantonese or certain other languages. Sorry, and thank you for telling us.
• Your currency now follows your region, so savings show in pounds, euros or dollars as you'd expect, whatever language your phone uses.
• Smoother and more reliable: fixes for rare crashes when the app opens, and the 30-day outlook now stays complete when the clocks change.
• If something ever does go wrong, you'll now see a clear message instead of a blank space.
• Loving Sun Hours? Pick the sun in Settings → Feedback to leave a review. Anything less than sunny? Tell us what to improve and it comes straight to the developer.… more - 🆕Sun Hours for Solar Panels: its developer released another app: Outflow: Subscription Tracker

Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Sun Hours for Solar Panels
Will your panels earn anything today? Sun Hours tells you in 8 seconds — just your postcode and your best-ever solar day. No inverter login. No azimuth. No account. No engineering degree.
THE FORECAST
Today's expected kWh before the kettle's boiled. An hour-by-hour generation curve so you know exactly when your panels peak. A 7-day solar forecast with cloud cover and efficiency breakdown for each day. And a 30-day view built from historical weather at your exact location — so you understand your site's full seasonal rhythm, not just this week.
SOL
Every morning, Sol — Sun Hours' pixel-art sun mascot — delivers a personal forecast for your panels before you've touched a chart. When today's forecast matches your all-time best generation day, Sol fires a notification: "It's a 100% day." The solar equivalent of a perfect score. You'll want to share it.
SUN HOURS ALERTS
Opt-in morning notifications that tell you your best two-hour solar window for the day. "Best window today: 11am–1pm." Charge the EV, run the dishwasher, fire up the immersion heater — on your own free electricity, not the grid's. The question every solar owner asks every morning, answered automatically.
SMART APPLIANCE TIMER
Tell Sun Hours what appliances you have. It tells you exactly when to run each one to land inside your solar peak. Washing machine, dishwasher, tumble dryer, EV top-up — scheduled around your free generation, not your habits.
TRAVEL MODE
Portable panels on a campervan? Camping with a folding kit? Drop a pin anywhere or use GPS and get an accurate solar forecast for that exact location — the Lake District, the Scottish Highlands, a clifftop in Cornwall, anywhere. One tap back to your home setup.
WORKS WITH EVERYTHING
Hoymiles, Deye, Marstek, Envertech, APS, Solis, Growatt — and every other rooftop or plug-in setup. No inverter integration needed. If it generates kWh, Sun Hours can forecast it.
ON IPAD AND MAC
The dashboard opens out into two columns on iPad, so today and the week ahead sit side by side rather than stacked, with the animated sky running edge to edge behind a frosted glass toolbar. The forecast accuracy grid uses the extra width and labels each month. It runs on an M-series Mac too.
Free to use. Infrequent, closeable ads. No account. No tracking. Your location never leaves your device.
Built in the UK for solar owners everywhere — by someone who got fed up with apps that made a simple question complicated.
