As fossil fuels get depleted, we certainly need to find alternative sources of power, don’t we? If you want clean, reliable power, then the best hydroelectric generator might be exactly what you need. Using water as a source of power is nothing new, and humans have used it for many years. Several ancient civilizations have records of using water bodies to create power and today, focus is shifting to creating cleaner, easier forms of energy. With the advent of technology, you can also join the movement, so to speak, and have your own hydroelectric generator.

There are quite a number of these generators on the market and it can be a tad cumbersome finding the option that would fit your requirements. Well, in this post, we reviewed five of the best options. In making this list, we considered important factors like voltage, watts, dimensions and weight, output, pressure resistance, and water pressure. We will discuss the importance of these factors in the buying guide. In the meantime, let’s consider our best picks.

Since the model is very compact, you will find it easy to handle and capable of getting power from small water bodies and pipes.

It is a low-cost option that will make good use of the water that you have in the home. It is cheap but will offer you good returns on your purchase. One of the best things about the model is that it can handle plenty of pressures, even better than several others on the market. It should be noted though, that these are a bit bulkier than the regular models in this category. Therefore, it can be somewhat harder to fit them into small spaces. Thus, before installing it, you must ensure that there is enough space to fit it in.

What makes it stand out? The KEENSO HYDROELECTRIC GENERATOR is an excellent model that will deliver power from the waterbodies on your property. It is affordable, lightweight, durable and useful for different water pressures.

Which disadvantages must you keep in mind? This model is somewhat bigger than your regular micro generator. Thus, you must have enough space for installation.

Things to Consider

In the section above, we reviewed five of the best hydroelectric generators that you can find right now. These units are excellent for generating small amounts of power in and around the home. The five options help to narrow your options. We promised to discuss the factors that affected our roundup, and in this section, we will look at these factors. Knowing about these will certainly assist you in choosing the right options on the market.

How Hydroelectric Generators Work

The working principle behind these generators is rather simple. They capture the energy of moving, falling or pressurized water to create electricity. They often have some type of turbine inside that converts the kinetic energy of the water intro mechanical energy, and this energy is then transformed into electrical energy. Water has been used for several centuries as a source of energy.

5 Best Hydroelectric Generators - Eco-Friendly Power

Before you head over to the market, you must be sure that you have the facilities to engage in such type of generation. The generator itself is just a minute part of the process. The most important factor that will determine whether you should invest in a hydroelectric generator is the accessibility to water. After all, if there isn’t a water source, it would be pointless getting the generator.

Therefore, consider the following questions: would you be camping near a river or a stream? Do you have running water on your property, in the form of lakes or streams? How much water runs through the pipes of your home, and what is the pressure?

The answers to these questions will go a long way in determining whether you should have a hydroelectric generator installed.

In the event that you don’t have these water bodies on the property, you can still manage to have a hydroelectric generator in the home. In this case, mini or micro generators like those we have considered on this roundup will come in pretty handy. These can be set up and connected to your plumbing system.
Examples include the Yosoo Micro Hydroelectric Power Generator and KEENSO HYDROELECTRIC GENERATOR.

Features to consider

Before buying a hydroelectric generator please consider the following first:

Water Source

One of the important things that will affect the option you choose is the type of body of water that you have available. If you are looking to generate plenty of electricity, you must consider the head and the flow of the water. Let’s see what these are.

The head refers to the vertical distance the water falls. The higher the distance, the more the pressure that will be generated. With more pressures comes more power.  If the head is not up to two feet, then using a hydroelectric generator would be pointless.

The flow is the amount of water that, well, flows through the water body, and it is essential to the amount of power that you can generate.


Another important feature to consider when buying a hydroelectric generator is the amount of power that you plan to produce. As with other types of generators on the market, hydroelectric generators generate different amounts of power. Some offer high watts output, while others are lower. The total amount of power is often indicated on the generator. The models that we have reviewed above offer around 10W. An example is the Pmsanzay Micro Hydroelectric Generator.


It is also important to consider the ease of installation. If you have a large hydroelectric generator, you will likely have to call on the help of a professional before you can set it up. The same thing goes for medium-sized models. If you don’t have sufficient DIY skills, it would be nearly impossible to install it yourself. And part of installation involves ensuring that you have the right conditions for setting up a hydroelectric generator.

If you do not have a lot of experience, then it would be better to choose a mini or micro hydroelectric generator. One of the advantages of these units is the ease of set up. Most of the options on the market, and all of the options reviewed in our roundup offer easy installation. They are often small and uncomplicated.
An example is the Tinsay Hydroelectric Generator.



There are five major types of hydroelectric generators. These are the cross-flow turbine, in-pipe micro, pelton wheel, portable, and multi-use. Most of the options that we have considered above are in-pipe options. These are connected to the piping system of the home and use the water from your showers and similar installations. The ApplianPar Yellow Micro Hydroelectric Generator is an example of an in-pipe hydroelectric generator.


Hydroelectricty is a renewable energy source that can go on for a long time. However, the generators used to create the power have their lifespan. The lifespan depends on different factors including the frequency of use, level of maintenance, the manufacturer, and others. If the model is from a reputable company, the generator can last for more than five years.

The noise level often depends on the size of the machine. Dams, which are a form of hydroelectric generators can produce sound of up to 120 decibels. However, smaller machines like the micro hydroelectric generators are usually very quiet.

Check out the terms and conditions of the machine. Whether a warranty is provided or not depends on the manufacturer. When making a buying choice, though, it is better to go for an option with a lengthy warranty period. That way you can make repairs or replace the machine at no additional costs.
