## What is PV Optimizer & Solar compass?

PV Optimizer & Solar compass is a tool intended to maximise the output of your solar panels.
To use the optimiser you only need to choose between one of the 4 time frames available (if you pretend to adjust your panels for the moment, every 3 months, 6 months or yearly), place your device above your panels, and adjust its azimuth and tilt according with the values given by the app.
PV optimizer's algorithm will make sure you get the most from your panels and don't waste any opportunity to increase your output.

This app also comes with a solar compass which you might find useful for optimizing your panels or for other activities, with plenty of real time data regarding solar position and radiation.

In version 2.0 we are proud to present you a forecast for your solar panels output. Just input your panel capacity, tilt and azimuth angles, and you'll get a forecast for the monthly energy you might generate in theory.

All the functionalities of this app are completely free.

## Key features

- Solar panel output maximization
- Azimuth and tilt adjustment guidance
- Real-time solar compass
- Solar panel output forecast
- Adjustable time frames for optimization

### 4/5 — No instructions and no rotation

*2025-11-11, version 2.44*

Once you’ve worked out how to use it, it works pretty well. But it took me quite a while to work if out and to make sure the phone’s calibration was set properly. There could be more guidance and it could be more obvious where to find it, as the guide feature doesn’t show on the opening page.

### 5/5 — Pour orienter les panneaux

*2024-12-29, version 2.44*

Simple fiable pratique !!!

### 5/5 — Utile pour incliner les panneaux photovoltaïques

*2024-10-30, version 2.44*

Je cherchais une application capable de donner l’inclinaison optimale des panneaux PV par mois. Celle-ci propose par an, 6 ou 3 mois mais aussi l’inclinaison optimale actuelle ce qui me suffit finalement. Les publicités sont pénibles mais j’ai payé pour les enlever et surtout récompenser le développeur : l’alignement optimal (azimut et inclinaison) se fait en une fois en posant le téléphone sur les panneaux.

### 1/5 — Seulement de la pub

*2024-10-20*

Impossible de l’utiliser, des popup de publicité ne se ferment pas. J’ai essayé d’attendre, de relancer. Je n’avais jamais vu cela avant. On clique en bas, direction un sponsor. À droite direction un sponsor, et seulement après plusieurs redémarrage pour se débarrasser du bandeau qui prend tout l’écran. Avec la rédaction de cet avis, c’est mon oscar annuel, même à vie, de perte de temps!

### 5/5 — Great must have app

*2024-02-25, version 2.44*

I wish I got this months ago. It’s excellent.  I’ve spent weeks writing a similar program (though it does all my panels and takes shading in account) but I have to commend the accuracy and simplicity of this app. Worth paying the trivial 99p to go ad free.  Well done.

### 1/5 — Doesn’t work anymore Useless

*2023-10-20, version 2.44*

Can’t use angle solar panel option anymore.
Error- iPhone gyroscope off.
My gyroscope works with other apps
My iPhone is updated & app is updated.
I tried deleting app & reinstall, still not working.
Any help to resolve would be appreciated

### 5/5 — Great for RV and Overland portable solar panel setup

*2022-12-13, version 2.44*

This is the best app I have used for finding optimal setup angles for our portable solar suitcases. The location and irradiance info help in estimating power generation so we can better budget usage. The position optimizer feature takes out most of the guesswork out of setup. A selection for a shorter time period like a day or week would make this app perfect for portable panel setup.

### 2/5 — PV Alignment not working

*2022-08-07, version 2.44*

I tried to use the Align function and keep getting an error “There was an error downloading relevant data….”. This could be a great app if all functions are working! (iphone 13,  iOS 15.6)

### 5/5 — Awesome

*2022-07-26, version 2.44*

This honestly get any Solar panel more power!!! 

I used a small 28w panel and was trying to get the best angle and this was it! I got the most out of it and now got a 100w panel which is working amazing with it too! Thank you!

### 3/5 — Nice but could be better.

*2022-06-22, version 2.43*

I use this every so often to align my panels. It would be nice though if the alignment tool adjusted to the time setting that you have set up. Sometimes it would be nice to adjust the panels at night.

## Frequently asked questions about PV Optimizer & Solar compass

### What does the PV Optimizer & Solar compass app do?

This app is designed to help you maximize the energy output of your solar panels. It provides guidance on adjusting your panels' azimuth and tilt angles based on real-time solar data. It also includes a solar compass and offers forecasts for your potential monthly energy generation.

### How do I use the solar panel optimizer feature?

To use the optimizer, select one of the four available time frames (momentary, 3 months, 6 months, or yearly). Then, place your device above your solar panels and adjust their azimuth and tilt according to the values provided by the app. The app's algorithm will then help you get the most from your panels.

### Is the PV Optimizer & Solar compass app free to use?

Yes, all the functionalities of this app are completely free. While the app has in-app purchases, the core features for optimizing solar panel output and using the solar compass are available without any cost.

### What kind of data does the solar compass provide?

The solar compass provides real-time data related to the sun's position and solar radiation. This information can be useful for optimizing your solar panels or for other outdoor activities where knowing the sun's location is important.

### Can I get a forecast for my solar panel energy generation?

Yes, version 2.0 of the app includes a forecast feature for your solar panels' output. You can input your panel capacity, tilt, and azimuth angles to receive a theoretical forecast of the monthly energy you might generate.
