We have received several inquiries about the possibility of running our repeaters on Solar Power. It should be do-able if we look at the specifications for the component devices. 


We show that the BCR-50V, BCR-40DU, BCR-220 units draw Tx max of 11.2 amps, with standby Rx of .3 amps.  Based on the DC Watts = Amps/Volts and a nominal of 13.8 volts and your anticipated duty cycle, you know exactly what you will need. 


Companies like Harbor Freight offer low-dollar gang-able solar panels along with power management controls, and there are some super efficient high-dollar options available as well.


Good Luck and let us know what you come up with (send pics) and tell us how well it works!
