This MPPT solar charger is build around Tim Nolans open source MPPT solar prototype project. I made a print layout for the MPPT solar charger, and below you can se how the mechanical mounting was meant to be.
This picture show a salvaged Pentium 4 cooling plate with fan mounted on top of it.
The complete MPPT solar charger is mounted to the cooling plate, using a aluminium U profile, where the MOSFETs and voltage regulator are placed.
To complete the mppt solar charger project, i still need to do some work with a plastic cabinet, and also i will make some kind of temperature controlled PWM speed adjustment for the fan.
