## PV Master Description
Thinking about going solar, or trying to get more out of the panels you already have? PV Master turns confusing solar numbers into clear decisions, so you spend less on power and waste less of the sun.

Using just your location, PV Master shows you what your roof can really do, when to rely on your own panels, and when to lean on the grid. Whether you are planning your first system or fine tuning an existing one, you get answers you can act on.

What PV Master helps you do:

Plan with real numbers, not guesses. Get accurate, location based solar data plus a live grid forecast, so you know the best times to use your own power and when cheaper grid power makes sense.

Position your panels for maximum output. The built in compass and tilt tool helps you find the angle that captures the most sun all year long.

Size your system with confidence. Simple calculators work out how much energy you need, how many panels and batteries it takes, and what it will cost, so you can weigh the ROI before you spend a cent.

Get more from every sunny day. Local weather is built in, so you can see how conditions affect production and plan around them.

Learn as you go. Clear guides, FAQs, and a plain language glossary explain every solar and photovoltaic term, so nothing holds you back.

It all lives in one friendly app, from first idea to finished install, with information that is genuinely easy to read.

Download PV Master today and start making smarter, greener energy decisions.

## PV Master Reviews in United States

### *---- "Apple needs to remove this app"
Does not work, and appears tha t stopped working in 2018 (as noted in comments below).  Where can I get a refund? 😡
-- roferpr, 2020-01-01

### *---- "Ing."
Used to love this app for 6 years, now it stopped working. Totally USELESS. Shame.
-- flautadanzon, 2018-11-17

### *---- "Won’t even find location"
Inputted latitude and longitude and then screen stays blank... wast of 9.99 :-(
-- kjsweden, 2018-11-06

### *---- "PV Master App"
This worked for the first week. Then it wouldn't open any more. Total POS!
-- Unhappy Purchaser 7, 2016-05-04

### *---- "Total piece of garbage!!"
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!!!
-- Murfdeezy, 2016-01-21

### **--- "B-Solar"
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
-- egg$138, 2013-01-23

### *---- "Database Unreachable"
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.
-- Northland5, 2011-05-08

### **--- "U.S. Nova Corporation"
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.
-- Garrbelly, 2011-05-08

### ****- "Could be better"
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.
