I didn't care for putting unnecessary holes into my walls so with some inspiration from another project I came up with this clip. The Somfy Solar panel is just long enough that these will fit on opposite ends of the battery and allow the panel to hang just below it. I printed it out in PLA and it fit perfectly on my blinds, however since they will technically sit in sunlight it may be better to print them in ASA... time will tell.
