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. 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. Solar cells are always .5 volts, no matter how large or small they are, they always pump out half a volt. There are two ways to wire power supplies (like batteries or solar cells) together. To wire in series you wire the positive wire from one power source into the negative wire or the other.
Build Naturally...Blog: Collaborate with the sun...passive solar design basics
Passive solar design takes advantage of solar orientation and other climate conditions to minimize (and in some conditions, eliminate) heating and cooling requirements for a building. The name says it all... PASSIVE = no mechanical parts & minimal if any maintenance SOLAR = uses (free) energy from the sun DESIGN = integrated into the building design The result is free heating (& cooling) that works because of how a building is design, so it cannot break. The basics are simple! 1. The easiest direction to control when the sun enters your space is from the South side (see #2 below). 2. Have you ever noticed that the angle of the sun in the sky is lower on the horizon in Winter and almost overhead in Summer? 3. The biggest mistake made with a passive solar home is to make the Windows on the South too large. You also need to consider the size of windows facing North, East, & West. 4. This simple strategy is often overlooked, but is quite effective. Recommended Reads
How I built an electricity producing Solar Panel
Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available. I built a wind turbine to provide some power on the remote property. Here is a video of the solar panel set up and in use on my remote, off-grid property. Let me state up front that I probably won't be able to help you out much if you decide to build your own solar panel(s). So what is a solar panel anyway? I started out the way I start every project, by Googling for information on home-built solar panels. seller. Oops!
A straw bale roundhouse, step by step.
The 7m diameter French roundhouse (6m internally) stands on a rubble trench [see picture 1] cut deep enough to reach below the frost line. This protects the building from movement in the winter when the ground above the frost line freezes and expands. The trench is filled with rubble over drainage pipes that channel out any water collected from above. A ring (often incorrectly called a henge) of debarked douglas fir roundwood, 15-20cm diameter, stands on stone pads that rest on the rubble trench [2] braced by six timbers to stop the frame twisting. The floor is a limecrete mortar consisting of 2 parts subsoil, 1 part sand, 2 parts pozzolane gravel (volcanic rock a bit like pumice) and 1 part lime (NHL5) poured over a geo textile sheet resting on a 15cm deep layer of stones. It's rare that any house is built by one person and this house was no different because Matthew had help from many hands including Tony, Joe, Kristian, Sam, Ali, Edouard and Guillaume.

DIY Solar Panels
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 X 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.
