The cold side of the thermoelectric generator is marked with numbers and letters. Using double sided thermally conductive sticky pads that come with the heat sinks connect them together. The heat sinks will be used to cool the cold side of the TEG

There is a capacitor attached to the middle of the solar panel so the two sets of solar panels will have to be glue slightly apart from each. The side without the numbers should be directly glued to the panel

The water acts as a heat sink for the TEG. The heat that is absorbed by the solar panel is transfered into the water heat sink chamber. The water, having a high heat capacity, slowly heats up. The water therefore helps keep a temperature difference across the module for longer periods of time. 

The Schottky diodes help keep the direction of current the same way. This is important because at times of  low temperature difference we don't want the solar cell to cause the TEG to become a load. The diodes should be wired so that the current flows from positive to negative.

All the housing parts were modeled and 3d printed. The designs did not take do a good job of taking into account the wires and new holes will be needed for wires to go through

At peak voltage this module is good to power a particle photon for data collection. I had it wired directly to a photon and a soil moisture sensor. The particle was receiving enough current to operate. I highly recommend wiring a solar lipo charger and a voltage booster into the device. This is so it can power a small battery.
