We use the same size panels for all the Units so they can be swapped on playa in the event of a repair. It also controls costs on fabricating units. The panels we use are industrial with aluminum frames and real glass that doesn’t scratch when we. clean them which extends their life. We have an opportunity to buy 3 Pallets of 27 panels at an incredible price which is almost half of what we need on our path to our 2030 goals of charging 200 batteries on playa.
