User reviews

Forecast accuracy

Every day the forecast is only 50 to 65 percent of actual. Is it because we are in the Northern Hemisphere and this is an Australian app? Is it Australian??
My settings are all correct.
I even tried putting in very wrong settings and it made no difference to the forecast.
Have I done something wrong?

Response from developer

Hi, thank you for the detailed feedback, and sorry for the frustration. Kilowatt works in both hemispheres, and you haven't done anything wrong. We'd like to look into your forecast together: please write to us at info@kilowattapp.com with a short description of your system, and we'll get back to you personally.

The most customisable and most accurate

Tried a few and Kilowatt was by far the best, even compared to the paid predication sub my system came with

Getting better by the day!

I have had this app for a few months now and originally the estimate was considerably out but I reached out to the Kilowatt team and they listened and asked questions which was great. The accuracy has improved dramatically for me and it is a worthwhile app for anyone with solar panels and particularly with batteries and wondering how much you need to charge! Thank you Team Kilowatt.

Les valeurs s’efface

Bon ben au début ça fonctionnait bien mais pour le mois de décembre déjà impossible de saisir la production du 29 au 31 décembre puis ensuite maintenant impossible de saisir la production de tout les premiers du mois !!! C chiant et j’envisage à tester d’autres applications !!!

Response from developer

Bonjour, Vous aviez raison, et notre réponse de mars ne réglait qu'une partie du problème. La saisie du 1er de chaque mois n'a été corrigée qu'en version 4.0.3 : un décalage de journée enregistrait votre valeur sur un autre jour, si bien que le 1er restait vide. La version 4.3.1, disponible aujourd'hui, contient ce correctif et celui des icônes manquantes. Une chose ne se répare pas toute seule : vos journées du 29 au 31 décembre ont été enregistrées sous l'année suivante à cause de l'ancien bug, et restent donc vides dans votre calendrier. Écrivez-nous à info@kilowattapp.com et nous les remettrons à la bonne date. Merci de nous l'avoir signalé deux fois — c'est ce qui a permis de le corriger. — L'équipe Kilowatt

Beaucoup de progrès à faire

Malheureusement cette application n’est vraiment pas au point. J’ai une production plus que doublé par rapport à ce qu’elle annonce même en rafraîchissant plusieurs dans la journée les valeurs changent en permanence. Je désinstalle l’application pour ma part. Heureusement que je n’ai pas acheté la version pro
