An Easy to Make Solar Wagon

Yesterday one of our readers sent in pictures of a solar system he built using two 180-watt solar panels.  This should produce a maximum of a 108 amp hours of power on a good sunny day.  You can see that he is using three deep cycle marine batteries.  There is a controller located between the panels and the batteries.

The inverter is a 2000-watt unit that you can purchase from stores like Harbor Freight and Tools.

With this cart, he can move it around the yard to take advantage of the sun.  You will notice that he has left room for additional batteries to be added in the future.  This unit has the capacity to support several more batteries.  This would give it more reserve power in case of bad weather.  This unit should run a refrigerator for 3 hours or so a day without any problems.

He stated that he uses his ATV to move the solar wagon.  In the future, he intends to put larger wheels on to make it easier to move over uneven ground.

This is very similar to the type of unit I am building.  The big difference between his and mine will be that I am using one 300 watts solar panel and mine will be designed for a more permanent installation. Here’s a close look at another solar wagon design that might be helpful to you.
