Welcome to the Northern Arizona Wind & Sun Solar Electric Store
** 2009 is our 30th anniversary - 1979 to 2009. For this occasion we are offering many solar panels at extra discounts, especially on the 130 to 210 watt Kyocera solar panels. ** -- There is no state sales tax on solar panels or solar electric systems in Arizona (local taxes may still apply). --
* We will be closed on Friday for the 4th of July holiday *
Testing charge controllers: Nearly all charge controller REQUIRE that they be hooked up to a battery in order to operate. You cannot hook up a solar panel to the input and use the LOAD or OUTPUT with no battery connected. Also, if you try to measure the volts or amps on those terminals with no battery, you will not get a valid reading.
** All About Charge Controllers ** - Not sure what a charge controller is, or what type you need, of if you even need one? Then read our Charge Controller FAQ first.
