What are the advantages of solar power for radio communications?
Solar power is ideal for radio communications as the DC power does not introduce line noise or 60 cycle hum. Isolation from the grid (in most installations) also will assure relative immunity from grid power surges. Using solar energy as a power source actually fulfills a prime mission of amateur radio: reliable emergency communications. Solar powered communications will function when everything else is off[line. Solar power can also keep a standby battery bank constantly topped-off and ready to use in the event of a power failure. UPS inverters are also available that switch power over to solar power upon a quarter-cycle failure of the 110VAC grid.
