I'm always happy to provide a convoluted answer to a simple question.
At this site, you can learn from my real world experiences
in solar energy production and how I produce power at our cabin in Northern
Michigan. The cabin is located right on the 45th parallel near Gaylord,
Michigan. Check out our photography
site which has some photos around the cabin in the nature and winter
sections.
While this format of the site will stay
here as it is, more of our updates and new articles will be in the new
format. Visit the
new format site here.

First of all, welcome to our site! We've been
around for several years and conduct all kinds of half baked DIY projects on our
show, This Old Shack. Be sure to check out all
of our half witted articles and pages. If you have questions, just Email
us and we will do our best to confuse you beyond all belief.
Disaster
planning should be part of every single household across America, strike that,
the world. When disaster strikes, people die or lives are c80%hanged. In times of
plenty, forego the Playstations and buy extra food. You can explain a lack of
toys better than a lack of food to your children.
In
1980 our military switched its entire food ration program over to the full
moisture MRE pouch system. These are the meals we tested on "This Old
Shack". Check
them out here.

Xantrex Charge Controller
07/21/2010
Note: we'll be replacing the C12 with a C35 charge controller once we have made our new solar panels (that's right, we're going to finally start building solar panels). At that point, we'll retire the C12 as a spare if we need it.
Update: Our Xantrex C12 charge controller has been in service since 2006. Since that time, we've had no problems with it aside from the "night light" feature going wacko one time a couple of years ago. The thing works great - we leave the shack and the bank is at 80% charge and when we get back it's 100%. The charge controller has 3 stages two of which are set by the user - bulk and absorption. The unit enters the float setting by itself.
This is a Xantrex C12, a 25 amp version of their C controllers. This particular model features Pulse Wave Modulation (PWM) charging. It has field settings for bulk charging, absorption charging and float charging. It also has settings for automatic equalization (or it can be done manually by pushing a switch). Unique to the C12 is a feature that will turn on 12 volt lights at night, what they call the "night light" feature.
The C12 also has a 12 volt distribution output for running 12 volt appliances up to 25 amps. A good place to order this controller from is Infinigi.com - I've ordered parts and supplies from them and they're very good with customer service.
You can download the specs. or the manual at www.xantrex.com
Here is how big the
controller is. It's about the size of my hand.
Here are two of the 1/2 inch conduit openings in the unit. There's another one on the back side for wall mounting.
The guts. You can see the POT settings on the right hand side. There are also test points so you can set the voltages almost exactly where you want them.

Solar-Frontier.com
provides the most economical, ecological solar energy solutions such as Solar
Panels on earth--on the world's largest scale.
There are several people on various newsgroups and discussion areas that waylay in uninformed or those just starting out in the off grid world of self power generation. This involves an almost religious belief in a phantom 6v golf cart true deep cycle battery that is superior in every way to any other battery in existence.
A simple examination of the specification sheet for a line of 6v and 12v off grid batteries will tell you quite clearly that there is no one single best solution for all circumstances. It is not accurate to say one is best.
Our system has been using the much maligned Harbor Freight 45 watt solar panel kits for 4 years. Over these years, we've moved them back and forth from the main home in Saline, Michigan to the shack in Gaylord. They've been dropped, exposed to heavy rain, snow, sleet, hail. One even has even had the glass on it shattered from a tree limb dropping on it.
Look, using testing equipment is all well and
good but those spec sheets don't mean squat if you can't run YOUR stuff
for as long as you want to. So what I do (so you don't have to) is get the
equipment (batteries, inverters, solar panels) and put what I run on it.
Usually about 30-50 watts at 12 volts - few amps of draw. You know, turning
lights on and off, running a computer (a laptop) and whatnot.
Throughout the test, a digital meter is run on
the bank and a hydrometer is used once an hour to determine whether the meter is
reading the correct voltage. During the sunlight hours on the panels, there is
another digital meter installed at the primary junction box (where the panels
feed into the 10 gauge cables that feed to the charge controller) that measures
panel voltage and amps.
One of the things that I like the best about
alternative energy is that you can make it as complicated or simple as you like.
Some people, even though they use alternative energy simply don't have a good
grasp on the entire substance that goes into the makeup of an engineered system
that has been built from scratch.
Don't ask me why, but I've recently become interested in
studying earthquake/volcano activity around the world; ash plumes and such. I've
added a page with RSS feeds and links to satellite imagery.
