Solar Food Dehydrator (Dryer) Dry your fruit, vegetables, and other goods with your own sun powered dehydrator.
Electric Food Dehydrators can be expensive and consume unnecessary energy. This solar dehydrator was made entirely of recovered materials. It was constructed with scrap ply wood, 2x4s from an old ladder, a house window, and other items which could be considered trash. It was created as a project at Maharishi University of Management in Fairfield, Iowa. Why We Dry: Removal of moisture prevents bacteria from ruining your values fruits and vegetables. How to build a Solar Panel - Home.
Welcome to The Sietch - Projects Build Your Own Solar Battery Charger. First we need an old window, I got mine from a construction site.
Its your basic old nasty basement window. Make sure you wash both sides of the glass well with soap and water and window cleaner, more dust means less light gets through to your solar cells. Next take your multi-meter and sit in a sunny spot (or under a flood lamp) and check all your cells to make sure they get about .5 volts per cell. You do this by gently (cells are REALLY fragile) putting the red on the front (make sure its on the little metal lines) and black on the back (any place) of each cell while it is in the sun. It should say about .5 volts. For this project I used 12 cells but you really only need 6. As you can see they all fit with a lot of room left over, if I wanted to I could have used this window for a larger project but I only need a battery charger for right now. Next we get down to the fun part, soldering. There are two ways to wire power supplies (like batteries or solar cells) together.
How to Make Inexpensive DIY Home-Built Solar Panels with Damaged Solar Cells from Ebay. Mike Davis is an astronomer.
To practice his hobby away from the light pollution of cities, he bought some land in a remote part of Arizona. But there was a problem: No electricity. But he's a resourceful fellow. He built some solar panels using inexpensive blemished and damaged solar cells from eBay! Read on for more photos and some technical details to give you an idea of how he did it. I bought a couple of bricks of 3 by 6 mono-crystalline solar cells. A solar panel is really just a shallow box. Next I cut two pieces of masonite pegboard to fit inside the wells. I laid out the cells on that grid pattern upside-down so I could solder them together. I used a low-wattage soldering iron and fine rosen-core solder. Here's what the solar panel looks like from the front. Here I am testing first half panel outside in the sun.
I drilled a hole in the back of the panel near the top for the wires to exit. [...] Here is the finished product, producing 18.8 volts and 3.05 amps in the sun.
