Solar System
This page outlines all of the information about the solar system.
Solar Panels#
I have decided to go with 3 x 365 Watt Solaria panels. I First heard about the Solaria panels from this video: Solar Power Kit Explained for a Van Build - Off Grid (link goes to the timestamp where they start talking about the panels)
I managed to find a supplier for the panels and they where willing to sell them to me as they weren't for a house project, but I got the impression they don't usually supply to people who aren't certified installers.
Solar Controller#
The solar panels have an open circuit voltage (Voc) of 48v, this is at 25 degrees, however I do have plans of spending time in teh snowy mountains and it can get down to - 5 or on rare occasion -10 so I ran the numbers through the Victron MPPT charge controller calculator and at those temperatures it calculates the panels could be pushing 53 volts:

Calculation results
The full results and selection details are available in this [PDF](http link to /mppt_calculator_2202-01-20T1549.pdf)
As a result of this the larger MPPT 250|70 solar controller is required, which I have ordered from Outback Marine.
