This site is still under construction. The idea is to collect and explain information for creating your own renewable energy collection-and-storage system that's as portable as possible.

For now, I've created three battery packs that are charged by one or two solar panels. Their capacities were 600Wh, 800Wh and 400Wh. This is more than enough for holiday use, but not meant for domestic installations.

Building a system like this requires a lot of knowledge from various fields. The information is all available online for free, but spread out and mostly difficult to find. The goal here is to have one place to find everything.

My name is Andreas Monitzer, and I'm actually a freelance software developer. However, I spent five years in an electronics school learning all of the basics needed for understanding the information presented here. All of the rest that is presented here is based on information I found online and by experiments I did myself.

Note that I'm not a legally certified electric or electronics expert. Everything you do based on information I give here is at your own risk. You're also encouraged to do your own research and experiments to find out more.

That said, if you want to contribute either improvements or point out mistakes, please contact me at (either English or German is fine). I don't plan to make this page a one-man show, and I will give credit where credit is due (unless you specifically decline).

Why this is not a forum or a public wiki? Well, the current changes to Internet law means that I would be held responsible for everything that is posted by Random People On The Internet. I don't want to have to deal with that, so consider this a curated page.

So, what's the call to action?

If you're interested in independent, renewable energy production, try making your own solar system! It's a very rewarding field, where you can get very far by connecting reasonably priced commercially available components into systems that provide a measuable benefit.
