Here is what i have going so far. The Motorola 10w 6.2v Zener Diode will be mounted to the plexi glass as well or i may have another Idea. The radiation shield will be will be mounted to the bottom of the box. I am using a voltaic 9W panel for my solar source.
Isn't the Zener supposed to be across the solar panel leads (rather than in line)? In the winter it should be inside the box to help with the heating but in summer it needs to be outside the box. It may also get too hot for plexiglass.

I noticed the battery just like stopped charging shortly after the previous post. is this because the solar panel isnt able to charge at this point? the LIPO battery current positive voltage gave me the indication that the battery isnt charging. the suncontrol board however has the power good and charging led's lit.
LIPO_Battery Bus Voltage: 3.95 V LIPO_Battery Shunt Voltage: 40.68 mV LIPO_Battery Load Voltage: 3.99 V LIPO_Battery Current 1: 406.80 mA
Solar Cell Bus Voltage 2: 4.50 V Solar Cell Shunt Voltage 2: -0.32 mV Solar Cell Load Voltage 2: 4.50 V Solar Cell Current 2: 3.20 mA
Output Bus Voltage 3: 5.13 V Output Shunt Voltage 3: 29.72 mV Output Load Voltage 3: 5.16 V Output Current 3: 297.20 mA
Does the output current have to be so high? Can you identify the components that draw the most? With the current setup you'll barely have enough oomph in the panel to recharge the battery in a meaningful way.

Yeah i am using a 3A+ and beginning to notice its too much. I probably should use the pi wireless 0 i have laying around. I bought the 3A+ for this project not knowing the power consumption is identical to the 3B+. i dont have anything hooked up other than whats necessary. Ok yeah i am using a 6.2v 10w motorola Zener with the panel below.
