Excellent App

This is a very well thought out and designed app. Visually pleasing very useful and surprisingly accurate. Handy also a general indication of weather. Recommended.

Obstacles

It would be great to be able to set a Start angle and an end angle which allows the sun to actually hit your pv cause living behind a hill dramatically reduces resonable expectations.

You’ve got the option with the hours but that requires weekly changes at least.

Simple and effective.

I’ve been looking for a simple app to give me a general idea of what kind of power to expect, particularly during the winter months, it helps me plan power usage in my van conversion. No adds, no faff.

I would suggest a feature where you can input your system, battery bank and panel size for example, and be given a rough projection of wattage you might gain through the day. But I appreciate that’s a big ask for a free app.

Excellent, pratique et fiable

Merci pour cette application réellement utile , superbement faite, très intuitive et pratique avec une interface d’une lisibilité au top !!!
J’ai croisé les prévisions avec les données mairies d’ensoleillement etc : c’est fiable
J’ai également comparé à ma production réelle : fiable aussi (même à la limite prudemment un tout petit peu sous-évalué.
Sincèrement bravo et merci
Une suggestion, si ce n’est pas trop galère : pouvoir importer l’historique réel de production de la station (en csv ou autre) afin de comparer, éventuellement affiner le réglage etc !

OK but not perfect

The generation graph has a scale labelled kWh. The figures are presumably Wh, not kWh! It might be easier to read on the small page if they actually were kWh.
Update! This app is going berserk. Today was extremely cloudy and I generated just 2.2kWh. Your app has predicted that I should get 1.9MWh.
…..and another thing: it’s now before midnight on Sunday, but your app says it’s Monday. The clocks changed yesterday, so it looks like the app doesn’t understand daylight saving time.
