Lightweight High Altitude Balloon Payload
designed for long duration flights

Similar projects worth following
HABEXpico is a lightweight high altitude balloon payload designed for long duration flights. Using superpressure balloons, HABEXpico can fly to specific altitudes and maintain a stable float. The payload is equipped with a GPS, microcontroller, and radio module for transmitting location and power status. To maximize energy efficiency, an on-board power management circuit charges the payload batteries using solar panels, while the microcontroller balances the use of payload subsystems.

What kind of radio module are you using on this?

  Are you sure? yes | no

Very cool, clean design. Any reason for cutting out the board for the solar cell area? I've used a smaller version of them and I don't remember anything in the documentation about that. I could have missed it though.

I realize you are using some monocrystalline photovoltaic cells (i recognize the IXYS cells) but I don't know if you will get get the power you expect out of them if they are at the incorrect angle.  I very much suggest looking into the use of amorphous photovoltaic cells because they aren't designed to work at a particular angle.  There is a lower maximum power that you can get but it will be more consistent regardless of their positioning.
