We use solar powered since 2010. We no longer have the access to the large amount of panels the we had in the past, but continue to produce enough power from our current mutant vehicle to cover mobility, a decent sound system, lights, tools, cellphone charging, air pumps etc.
La Chiva Electrica; our mutant vehicle is one of the few solar beasts roomanig and blasting sound at BRC; we detest noisy generators and love our pure sound at camp or around. As per radical inclusion we do not detest non noisy generators.
The system consists of:
8 deep cycle 6v 340 amp hour batteries forming a theoretical 18 kwh storage unit.
1 – Outback power FX3648 pure sine wave inverter 
2 – MX60 Charge controllers 
2 – Junction boxes
6 – 190w/h panels.
in 2010 we had 4 panels.
in 2011 we had 12 panels.
in 2012 we had 20 panels.
in 2013 we had 19 panels.
in 2014 we had 19 panels.
In 2015 we had 6 panels; on top of the chiva.
In 2016 we had 6 panels; on top of the chiva.
In 2017 we had 6 panels; on top of the chiva.
Apart from this system we have smaller 12v panels charging independent deep cycle batteries for LED lights and other 12 volt stuff.
