Water Turbine Generators Buyer’s Guide

Picking the right one will depend on several different variables and it’s important to understand these before making a decision. And to be clear, there is a bit of math and physics involved here. To help you understand the devices and ensure you’re choosing the right type and model, we’ve put together this comprehensive buyer’s guide about water turbine generators and how they work.

Types of Water Turbine Generators

There are several types of water turbine generators, from large-scale models that are more for commercial use, to medium sized options for powering homes, to mini and portable models that are far easier to use though much less effective. We’ll go over the latter three options to help clarify their uses and functions.

• Medium Sized

This type of device is a more large scale option designed to harness energy from a body of water near or on your property. It’s difficult to install but does generate a significant amount of power when functioning at its peak. Before investing in a water turbine generator like this, you’ll need to know the flow and head of the river you’ll be using. To find those numbers, you’ll need to do some rather complex math. So a system like this would really require a professional to install. But if that’s something you’re considering for your home, be sure to consult an expert.

• Portable

The portable water turbine generators are ideal for folks who do a lot of outdoor recreational activities. You’ve probably seen solar charging units, and these are a lot like those in purpose and function. They’re designed to harness the energy of a river when access to an electric grid is not available. They’re easy to use and don’t require installation. You simply attach it to a rock or riverbank and let the flow of the river juice up your devices. The benefit of this type of product versus a solar charger is that it can function in day or night, and they tend to be a bit sturdier. However, without access to a river they aren’t helpful.

• Mini/Micro Water Turbine Generators

Designed to attach right onto your pipes, these little devices are handy and affordable. They screw right onto a faucet or pipe and turn your pressurized water into usable energy. Though they don’t generate a ton of wattage, they are effective in their own right. Use them with rechargeable battery units to keep LED lights or small devices charged without using your home’s electricity source. When purchasing one of these, keep in mind the psi of your plumbing system. Higher pressure is required to get the most out of them. Otherwise, they’re easy to use and perfect for implementing a small amount of clean energy into your overall electricity consumption.

What Do You Need to Power

Choosing the right water turbine generator ultimately comes down to this question. For reference, the average home uses over 10,000 kilowatt-hours per month, which translates to several thousand watts. So if powering your home is what you have in mind, then micro and portable options (even likely medium sized options) are not going to come anywhere near what you need. But if you’re just looking to charge small devices or LED lights, or possibly just generate some backup power in case of an outage, the in-pipe and portable models will all produce enough juice to meet your needs. A smartphone, for example, uses between 2 and 6 watts, so a 10 watt water turbine generator will produce enough energy to charge the phone twice.

Access to Water

Of course this goes without saying, but it’s important to remember that water turbine generators require a flow that will generate enough kinetic energy to actually convert into energy. The smaller units will work with minimal flow, but it’ll take far longer to actually produce a useable amount of juice. Natural flowing and pressurized water all have different psi, so bear that in mind. If you’ll be relying on the pipes in your house, it would be in your best interest to check the pressure beforehand to ensure you’re getting enough to utilize the water turbine generator effectively. If you’re using a portable device, you shouldn’t need to actually calculate the head and flow of the stream or river. More than likely, even a slow stream will be sufficient. Just remember, the more pressure the more power.

The Conclusion

As a means of alternative, clean energy, small water turbine generators are a low-cost solution that anyone can implement with relative ease. For emergency backup or to charge phones or other handheld devices, they produce the power you’ll need for the most part. But since there are so many variables to consider first, it’s critical that you’re prepared before you make an investment. Knowing how they work and understanding your specific power demands is essential to picking a product that’s actually going to work the way you need it to. Be sure to use this buyer’s guide when purchasing a water turbine generator so you can ensure you get the type and model that’s best for your needs.
