PV Master - Solar Panel System

Just wasted my 10 dollars here.. It crashes immediately after launch.

Does not work, and appears tha t stopped working in 2018 (as noted in comments below). Where can I get a refund? 😡

Used to love this app for 6 years, now it stopped working. Totally USELESS. Shame.

Inputted latitude and longitude and then screen stays blank... wast of 9.99 :-(

This worked for the first week. Then it wouldn't open any more. Total POS!

I bought this app in hopes of having a handy PV calculator or some other resources available on my phone. Piece of crap literally never even opened once!!! Crash. Crash. Crash. Total scam!!!

I thought it would do more I know how to do most of these calculations on paper....the data could be handy if I traveled to install PV in different regions I suppose....the glossary is nice to have.....I should have kept the Lite free version

I've been trying to get this to work as well but the database returns an 'err' message and there's no troubleshooting guide either. I'll be contacting Apple for a refund as well.

It has been an hour now and the app is still trying to connect to the remote database. I'm starting to wonder if there really is a data base. There does not seem to be a way to contact the developer in any way. Will try to get in touch with Apple to see if I can get a refund for this app. Shame, I really wanted it to work.

I use this in my iPhone 4. It displays almost all the statistics I need for my location, running a small 600 watt per day system. The battery and panel calculators are handy. These things could be better: * The borderless "Manual coordinates" button on the main menu is too tiny and hard to click. * When you click a field to enter a decimal, the text keyboard opens. * Overall performance is slow. * Statistics only displayed properly when viewed in landscape. * This has a really boring interface. Don't get me wrong, this is a good app and I give 4 stars. For $12 this app should be better.
