PV Solar Tilt

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

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

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

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

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.

Paid for the upgrade and will not work

This app is tremendous but the one big flaw is that the time for the daily or hourly angle is not local but rather is set for Switzerland. It would be nice if they could set it to show based on my local time instead of me having to do math. Otherwise, it is great.

I read the developers response to another person who had the same problem. After stopping the app and restarting it a few times the extra cost features (daily & hourly angles) began to work. The next day the same problem returned and after restarting the program twice, it still would not prove the daily or hourly tilt angle.

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!

App froze up after I purchased the license, none of the features (daily, hourly) seem to work, and I can’t change the location. Seems like a good idea but broken
