Some comments about this we saw on the web:

* /u/tardhat on /r/BurningMan late response, but maybe it’s still useful to you: I’ve used mine at local events (Utah) and it works pretty fantastically. Don’t waste your packing space with portable battery packs if you can avoid it. I spent about $50 on this little solar panel to run the fans ( https://www.amazon.com/gp/product/B012YUJJM8 ) and it makes it so the fans turn on when the sun’s up and off when it goes down.

I’ve been able to sleep in until 4 in the afternoon without the fans. With the fans, the interior basically cannot get above ambient temp. It is quite dark inside as the only light coming through is from the couple inches of gap at the bottom where the fly floats just above the ground. The vestibules are huge too. Cooler doesn’t have to come inside the sleeping area of the tent and doesn’t soak heat from the ground since the ground is never getting any sun.

——* /u/willrobot on /r/BurningMan Solar works really really well without a lot of infrastructure or investment. A cheap camping panel, charge controller, and inverter can cost you a couple hundred bucks new, less if you can scavenge, solder and dumpster dive. Add a $80 deep cycle marine battery and you can keep some lights, your usb batteries, and a few devices happy all week.

Stepping back a bit I use one of these https://www.amazon.com/Anker-Charger-PowerPort-iPhone-Galaxy/dp/B012YUJJM8/ref=sr_1_1_sspa?ie=UTF8&qid=1514404002&sr=8-1-spons&keywords=backpack+solar+panel&psc=1

It outputs directly to USB and keeps a couple battery packs I run LEDs off of and a small tablet I use for an occasional late night movie going all week. It’s light and folds up into my backpack quite well. It’s been going strong for three years now.
