How to Make Any Home Appliance Into a Solar Electric Hybrid

The biggest problem with implementing residential solar power is the start up cost. Home solar systems can cost tens of thousands of dollars and most families just can't afford it. So I came up with an idea for scaling a solar electric system down to make it cheaper and easier to implement. By designing a system for a single appliance, all the parts can be smaller/cheaper and it doesn't require any rewiring of the home's electrical system.

Here are the basics. A solar panel charges a battery. When the battery is fully charged, the system turns on a power inverter and switches the appliance from running on grid power to running on the solar power that is stored in the battery. When the battery gets low, the system automatically switches the appliance back to running on grid power. By using the solar power on a duty cycle, you take full advantage of all the available solar power.

I built a simple system that periodically powers a desk lamp for less than $200

For step by step instructions on how to build one of these systems, check out my Instructables page:

  8. This is going to be my first follow thru instruct able. NO experience doing circuit boards but this project is PERFECT for my needs. I am have a problem with the control circuit list.The optional items what are they needed for and what happens if not used? How about a picture of the backside of the board? So I can see the traces please.

    1. The optional parts are for a charge controller circuit that prevents the battery from being over charged. But this isn't necessary if you regularly turn on the appliance. Sorry, I don't have the original board anymore. I gave it to a friend. So I can't get any new pictures of it. You will just have to follow the circuit diagram.
