Welcome to the Northern Arizona Wind & Sun Solar Electric Store

Northern Arizona Wind & Sun is one of the pioneer solar power companies, and has been in the solar electric business since 1979. We stock a complete range of solar panels, inverters, deep cycle batteries, and hundreds of other DC power and solar power related products.

** 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 *

Solar Charge Controllers
A charge controller, or solar controller, regulates the voltage and current coming from your solar panels to your batteries.

Depending on the type and brand, solar panels put out ~16 to 50+ volts, so if there is no regulation the batteries may be damaged from overcharging. Generally, there is no need for a charge controller with the small trickle charge panels, such as the 1 to 5 watt panels. A rough rule is that if the panel puts out 1/60th or less per day of the rated battery amp-hour capacity, you don't need one.

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.

Not sure what MPPT is and why it is neat? Read this page about power tracking controllers on our technical information website.
