How To Find Parts For Wind Turbines And Solar Panels

How To Find Parts For Wind Turbines And Solar Panels

A couple of you have asked recently where to find some of the parts needed to build an alternative energy system, in particular some of the hard to find items for wind turbines.

Today I want to tell you where I found most of the stuff I used when building them.

Motors For Wind Turbines

The best place for getting motors (especially Ametek motors) was ebay. They’re still available there (like from this guy) but they’re a bit more expensive than they used to be.

Nowadays, you might see if you can pick up a broken (or well used) treadmill on your local Craigslist site. They usually don’t go for too much and while sometimes they won’t work, most of the time you get a pretty good one for little cost.

EBay is also a great source for solar cells for building your own solar panels.

Buying Batteries

No super dark secret here. Deep cycle batteries, especially marine batteries, are great. You can often find golf cart batteries relatively inexpensively.

I’ve also heard of some folks using batteries from fork lifts, but I don’t really have any personal experience with that.

Like I’ve said before though, don’t use car batteries. They can’t handle the charge cycles.

Finding A Power Inverter and Charge Controller

As with most things wherever possible, Amazon is my source of choice. This charge controller here is a good entry level one, but it’s probably not one that you’ll use for long term purposes. But for playing around and experiementing it’s a good inexpensive option. You’ll want to step up to something a bit more robust if you want to go whole hog with it.

For inverters, no specific recommendations since sizing is pretty much unique from situation to situation, but as I posted last week, a combination between true sine wave and modified sine wave inverters isn’t a bad way to go unless you’re doing a whole house system.

Anyhow, enough for tonight. Let me know if there’s anything else I can help you with!

Designing Emergency Power Systems For Medical Equipment: Intro!

Recently a reader asked a question I wanted to answer more broadly and definitely publically. The topic was about how to deal with electrically powered medical equipment in an emergency. The actual question was for a specific type of equipment, but the answer is definitely broadly applicable. There’s three major things to consider here, and… Continue Reading

DIY Alternative Energy

DIY Alternative Energy

Last year, I believe it was, I worked with a friend of mine to put together an e-course on DIY alternate energy. It’s been sitting on a shelf for a while, and I thought now would be a good time to throw it out there for folks to try and get some feedback. Well, technically… Continue Reading

Alternative Energy Options

Alternative Energy Options

I want to take a few moments today to write about alternative energy.  Now I don’t advocate this because I am a believer in man-made global warming.  Quite the contrary, I believe it is a complete fraud. However, that doesn’t mean that we should ignore alternative energy sources just because the Al Gore crowd thinks… Continue Reading

Secure Internet Based Communication Options

Secure Internet Based Communication Options

Lately there has been an upswing in the amount of news I’ve read talking about internet surveillance, snooping, and the like.  In fact, China redirected massive parts of the Internet’s e-mail flow through its own servers for a few months before it was detected.  Wonder why they’d do that? Sooner or later, we all have… Continue Reading

How To Choose The Right Generator

A reader recently emailed me and asked about choosing a generator. She in particular wanted to understand the differences in fuel types. So I thought instead of just sending her a reply directly I’d post my response here so everyone benefits! The broad answer is that there are two main things to consider when choosing… Continue Reading
