Solar power setup for Field Day

This is the solar setup I will be using for field day this year. It has a total of 400 Watts of solar panel along with a 120 Ah 12V deep cycle marine battery. I will be running QRP at around 20 watts which will allow me to be completely self powered for the entire weekend with no generator help. The panels are made my Renogy and here is a link to Amazon where I purchased them:
