## What is PV Solar Tilt?

Simple and accurate determination of the optimal PV tilt angle. Make your PV System generates maximum electricity for your desired location. The wrong position of your PV System can cause losses in electricity generation and your project feasibility may be a question.

With this App you will obtain:
- Solar Data charts (elevation, azimuth, sunrise, sunset time, noon time, sunlight duration, etc.)
- Tilt vs azimuth optimization (find the ideal tilt angle for any chosen azimuth)
- Optimal Tilt angle for any desired location on the map
- Optimal orientation
- Optimal monthly tilt angle
- Optimal daily tilt angle
- Optimal hourly tilt angle
- On-site inclinometer for measuring angles

The tilt angle of the panels is one of the most important parameters for your PV system. It is the angle at which the photovoltaic panels are set to face the sun relative to a horizontal position. The panels must have appropriate tilt angle, set for gaining maximum possible electricity from your PV system for your location. PV Solar Tilt is using optimization model for obtaining the most appropriate tilt angle of your panels in order to gain maximum electricity generation from your system.

The model is based on sophisticated simulations for maximizing energy yield for a given location.

### 5/5 — Update.  Premium finally back after a few months

*2026-05-13, version 20.0*

My premium features were gone from January to May, now finally back!  Thanks Igor! 

I have loved this app, Optimal Tilt, and found it very useful in adjusting my ground mounted solar panel’s angle each month in order to have the best production. 

However, when I just opened the app, it now only shows the optimal annual tilt!  This ruins the whole point of the app!  Before, I could depend on the app to tell me the optimal tilt for any month, day, and even the hour during any given day!  Now, it is useless! 

I only gave my previous review 3 stars, because even though I paid for a lifetime license, it still showed ads, and not all features were showing.  
But it’s fixed!  All is now well, no ads, and everything is working like it’s supposed to.  For anyone with a solar system, especially with an adjustable ground mounted rack, or who is contemplating a new system and wanting to know what angle will work best for each month, day, or even hour, this app is really great!  Yet very simple to use!  A very worthwhile app to have!

### 5/5 — Premium upgrade is worthless. Don’t pay for it

*2026-02-13, version 19.0*

Got taken by this unscrupulous developer.  Paid for the premium to get the daily recommendation    Tried deleting and reinstalling and resetting the internet connection but the app still asks to be paid.

### 5/5 — Update to my previous 3 star review

*2025-08-15, version 19.0*

Igor is the best!  I discovered an issue with the app not showing more than just basic yearly information, even though I have the lifetime premium version, and contacted him about it.  He got back to me the same day with a few questions which I answered.  The next day he emailed me to let me know it was fixed and to be sure I had version 19.0.  I updated it, and viola!  It’s now working!  A one day turn around and resolution!  Igor is the best! 

I updated my review shown below, and gave one star because of the issues I’m having, and also emailed Igor about it.  I have deleted and re-installed the app a few times, but so far, no change.  But after doing so, I noticed that it appeared that there must be some kind of temporary glitch going on.  And then very quickly Igor emailed me to try to resolve what’s going on.  That says a lot, because any product or app is bound to have an issue now and then.  But what makes a successful company, product, or app, is those who not only stand behind the app, but are quick to respond, as Igor is doing.  So I have restored my 5 star rating.  Here’s hoping we can get this resolved soon.  

Hello, 

I have loved this app, Optimal Tilt, and found it very useful in adjusting my ground mounted solar panel’s angle each month in order to have the best production. 

However, when I just opened the app, it now only shows the optimal annual tilt!  This ruins the whole point of the app!  Before, I could depend on the app to tell me the optimal tilt for any month, day, and even the hour during any given day!  Now, it is useless! 

I have tried to see if settings, swiping up, down, left, or right, but I don’t see any way to see anything more than the useless annual tilt!  

PLEASE RESTORE THE FEATURES THAT I PAID FOR AND THAT MADE THIS A USEFUL APP!

### 1/5 — Incorrect tilt angle calculations

*2025-06-15, version 17.0*

If you submit a location like Aleppo in Syria, it says the tilt angle should be 0 while it should be 9 to 10 ideally

### 1/5 — Daily Angle is not correct

*2024-05-05, version 13.0*

Today is May 5 in San Carlos, CA. I queried three solar tilt applications go determine the optimal tilt angle to set my portable panels to today. 

Tilt (this app) says 12 degrees 
Sun Seeker says 21 degrees
Simply Solar says 20 degrees

### 1/5 — Tilt is off always

*2023-11-07, version 11.0*

Always tells me to tilt my panel AWAY from the sun.

### 1/5 — -32, 115

*2023-07-14*

Unfortunately, doesn’t calculations correctly when locations are south of equator.

### 1/5 — There is no tutorial

*2023-03-17, version 11.0*

I’m sure the app works great but the ui is not straightforward and there’s no explanation to how to actually use this app in relation to solar systems. As a complete beginner it is pretty useless.

### 1/5 — Paid the lifetime fee for…. Nothing I guess

*2022-12-16, version 9.0*

The app is still showing me annul only even though I paid for the day/hourly….. I finally got to try my first pair of 180 watt solar panels in series today and sadly a pop can was what I had to rely on after purchasing this app thinking I was “smart”. I’ve opened and closed the app several times and nothing just annul only… I only bought for hourly for camping but looks like I was robbed . Now I can’t find anywhere to get a refund and apple says the app doesnit have a receipt…. Well it sure gone from my bank…. Thanks optimal tilt.. for nothing

### 2/5 — Paid to upgrade and made no difference

*2022-10-12, version 9.0*

I wanted the daily and hourly feature, so I paid to upgrade this app. Despite exiting the app and restarting this app several times, as recommended by the dev in another review, my upgraded features are still not working. Waste of money.
