PV Optimizer & Solar compass reviews
4.6 out of 5, based on 807 reviews.
What people like
- Great for finding panel angles
- Very useful for installers
- Simple and accurate calculator
What they complain about
- Crashes instantly on startup
- Ads won't close properly
- Gyroscope alignment feature broken
Great must have app
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.
Seulement de la pub
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!
No instructions and no rotation
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.
PV Alignment not working
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)
Nice but could be better.
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.
Great for RV and Overland portable solar panel setup
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.
Doesn’t work anymore Useless
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
Good but...
Would be better if there was a 'reverse' option to allow the iPhone to be pressed up against the underside of the panel, so the display pointed down. My panel is mounted so that without scaffolding I can't see the iPhone screen when it is sat on the front of the panel
Issue with the graph
Over 7MWH graph shows 1’s and 0’s. Below that seems to be ok. Descriptions need work and there should be a setting for inverter clipping.
Great app. Useful but crashes on IOS 8.4
Great app. Useful but crashes on IOS 8.4
Awesome
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!
No gyro connection problem
I use to love and use the app. But it has problems connecting with the gyroscope now. Maybe from an iOS update? Please update the app! Thanks
Useful and unique
Extremely useful for tuning your solar panels. Two feature requests: Tips for how to use the solar compass Ability to get azimuth/tilt for an arbitrary date/time. Often I'd like to know where to set my panels for the next morning.
Forecast agorithm incorrect?
Put in 1000W panel. Fixed, zero tilt (ie horizontal) and zero azimuth (North). Forecast output is 1771 kWh/yr (I’m in Spain). Changing the azimuth to 180 (but still horizontal) yields a forecast of 1513. Something’s wrong in the way it’s calculating? Makes me distrust it Is this a bug Jaoe?
Great for DIY Solar Installations
This is a great app to optimize solar installations and compute ROI.
Crashes
Repeatedly crashes after opening.
Lebanon
There was an error downloading relevant data for PV Optimizer to work. We are very sorry for the inconvenient. Please try again later.
Incorrect results?
This app is telling me that here in the Bay Area my optimal azimuth is 306 degrees and optimal tilt is -79 degrees. Huh?
Amazing app
As a one man PV install business, I find this app extremely useful. And it’s free. The only bug I have found is that when getting your yearly output in MWh, the scale on the graph breaks down. The values are rounded without decimals. And also one feature request - some sort of loss calculation (% or $) for incorrect PV orientation. Would be helpful to consider how far off can it be to have reasonable payoff time Anyway, thank you
Crap. Crashes instantly!
Crap. Crashes instantly!

Excellent app for alignment solar panels
Looks good but crashes
The app looks good. It has all the info I would like to get at - but it crashes a few seconds after startup making it unusable. Only 1 star rating because of crashing problem.
Very good
This is a great quick PV calculator and even better, free.
Crashes instantly - worthless
If you are looking for an app that crashes faster than any other app, look no further. I'm impressed with how fast the app crashes. It barely loads the splash screen before failing. The developers have really outdone themselves with the speed of this app failing. Kudos to the QA team for ensuring rapid failure.
Works great
Using the free version
Thanks
I use this all the time
