This is a solar powered trailer that I built. It uses a 115 watt solar module built by Evergreen Solar. The maximum real-time usable wattage I have gotten was about 70 watts, thats wattage comming directly from the panel without using a battery.

  • Why the trailer ? Do us use it to power an RV ?

  • @JimbowT I use it to show that it is possible. Most who saw the Solar Trailer in public, had seen solar power in the books and the tv, but never right in front of them in operation. But it has been powering my house through a second electrical system that I have since built.

  • Looks nice I never thought of using a cap for the inveter. Do you run the panel into the cap then into the inverter. dose it act like a filter/ regulator for the inverter?

  • @VWRabbitdiesel An inverter wants to see 2 things when you first turn it on: 1-Voltage, 2-Current. If I hooked the inverter to the charge controller, without the cap, it would not work. The Cap provides the current, along with the voltage, that the inverter wants to see when it starts up.

  • Wow, you really know what you are doing! =) Great job!

  • Although it may not seem as powerful to what we are used to, when monopolies make energy unaffordable- this is the answer. When we refuse to be controlled by those who want to hold us prisoner to life's essentials, the sun and wind will offer freely. Inventors such as this are giving us hands to receive what nature offers us for free, empowering us all. Thanks Dale!

  • my inverter runs off my batterys never thought about a capacitor

    good info thanks.

  • @VWRabbitdiesel Yup. Got it from Circuit City before they shut down for $130.00.

  • @SSparks555 is it a car stereo CAP?

  • @VWRabbitdiesel Actually, the cap acts more like a battery, kind of. In this non-battery based set-up, I have the panel going into the charge controller, which keeps the capacitor at 12 volts (without the charge controller the voltage would jump to 18 volts and the inverter would shut down due to over-voltage. Then the inverter is hooked up to the capacitor, which gives me 110 volts @ 75 watts directly from the sunlight.

  • Nice man, I never thought of using a capacitor as a battery before.......That really makes sense, especially if you want to reserve the battery for when there is no sun or just lower the cycles on it.

  • POwer to the people!!!!
