We should add a temperature sensor to the interior of the Version 2 solar cells. A good sensor is LM35AH, good accuracy and output of 10mV/C.

To get bipolar output from single power supply:
We should glue one of these onto the plexiglass mount or onto the solar cell itself. Then we need to add a 4 pin bulkhead connector. Picked 6 pins since it's always good to have extras

And add the two diodes and the 18K resistor internal to the package.
Bought 6 pin bulkhead solder connectors from Amazon
better connectors from Ebay:
Also bought panel DVM for direct readout of temperature.
