### 5/5 — The most customisable and most accurate

*2026-05-15*

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

### 5/5 — Getting better by the day!

*2026-03-22*

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.

### 2/5 — Les valeurs s’efface

*2026-03-06*

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 !!!

**Developer response:** Cher client,
Merci pour votre commentaire. Nous vous invitons à effectuer la mise à jour vers la version 3.2.9, qui résout le problème que vous avez signalé.
La version web fonctionne désormais correctement elle aussi.

### 1/5 — Beaucoup de progrès à faire

*2024-12-07*

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

**Developer response:** Nous sommes désolés que vous n'ayez pas trouvé notre application utile. 
Nous essayons de donner la même fiabilité aux systèmes de tous nos utilisateurs, quelle que soit la position géographique, l'exposition, l'orientation et les prévisions météorologiques locales. 
Nous donnons la possibilité de l'essayer gratuitement précisément parce que la fiabilité dépend encore de nombreux facteurs. 

Merci pour vos commentaires

### 4/5 — Helpful app

*2024-06-08*

I like the app. I wish it included an option to manually add daily usage in kw, to supplement tracking system net production. The forecasting based on location and weather conditions is pretty slick.

**Developer response:** hi JsmartAK,
thank you for reviewing us.
In order to improve the product, we are interested in hearing your feedback.
You can contact us at kilowattinfoapp@gmail.com
Best regards

### 5/5 — Excellent summary of sunshine forecast

*2023-10-29*

This looks to be an early version app but it has the best hourly data list of today’s remaining forecast production based upon your location and array details. It gives a weekly forecast as well. And best of all at least for now, it’s COMPLETELY FREE. No other apps out there give the relevant data to make home load decisions for the current and upcoming day.

The main room for improvement is improving the font/formatting which is currently clipping text/data at least on my iPhone

### 2/5 — Doesn’t work

*2023-10-12*

Doesn’t work

### 3/5 — Solar Forcaster

*2023-01-31*

Interesting app that I’m using to see whether I can justify getting PV panels and a home battery system.

It has the most detailed data that I have seen on any solar forecasting app but it let down by the fact that it does not require you to input your tilt angle and direction that the panels face eg 180 degrees.

It’s giving me far more optimistic readings compared to other apps that do require tilt and direction so I think it will be interesting to see how accurate these readings are when my PV panels arrive.

**Developer response:** Hi North's Lost Generation 1980s,
we have released a completely new version in terms of interface and functionality, which also includes the possibility of entering panel orientation.
We invite you to try it out and give us your feedback.

Best regards

### 1/5 — Nice app confusing expensive charging model

*2022-11-07*

Nice app

But please set fixed monthly/yearly price all this credits used for an update is unclear and expensive- deleted app

**Developer response:** Hi grumpy39,
Thanks for your feedback. 
We are in the process of releasing an update that changes the current package and subscription offering by making it easier to update estimates.
There will be only one subscription with no usage limit regarding the updating of estimates. We hope you can use Kilowatt again.
Thank you bye
