When looking for the perfect solar generator kit, one of the top priorities is the solar panel itself. There are a few details that should be considered such as size, durability, type, and the total number of panels needed.

Solar panels can range in their measurements. It’s important to know how many panels are needed for your electricity consumption so that you can choose a panel that fits properly on your mounting location.

Durability is another essential aspect of solar panels. All of the solar panels included in our list of the 7 Best DIY Solar Generator Kits are constructed from high-quality and long-lasting materials. The more durable your solar panel the longer its lifespan.

Finally, panel type is a factor you may want to consider. Monocrystalline solar panels are more efficient than Polycrystalline panels, though often include a higher price tag. Of course, higher quality solar panels mean faster and more efficient charging.

Charge Controller

Charge controllers are essential for regulating the amount of power that gets transferred to the battery. In turn, this keeps the battery from incurring any damage due to an excess of charge coming from the solar panels.

The two main types of charge controllers are PWM and MPPT controllers. PWM (pulse-width modulation controller) is the most common and cost-effective type of charge controller, however a MPPT (maximum power point tracking) charge controller can operate more efficiently and work well with a larger solar generator system.

Mounting kits

Depending on where you plan on mounting your solar panels, you’ll want to choose the correct mounting kit. Most of the options on our list of the Best DIY Solar Generators include Z mounting brackets. These types of brackets allow for easy installation on roofs and other flat surfaces.

Although Z mounting brackets are fairly universal, they will not work for every setup. For instance, if you intend on mounting your solar panels on a pole or similar structure, you’ll want to choose a proper mounting kit.

Cable Housing & Retention Devices

In order to connect multiple solar panels to achieve your desired energy output, you’ll need branch connectors. Branch connectors allow you to attach multiple solar panels to one system. Quality is important with these connectors.

Look for branch connectors that are both waterproof and dustproof, so you can be confident that they’ll last in an outdoor environment. Check out our guide on the different types of solar panel connectors. 


solar power inverter

An inverter is essentially the piece of equipment that enables you to provide power to all of your everyday devices and appliances. By converting DC energy to AC energy, the inverter makes all of the stored solar energy accessible.

Some of the DIY solar generator kits on our list include inverters, while others will require the addition of an inverter to complete the overall setup. The output capacity of your inverter is important to note, as you want to have a wattage output that aligns with your desired energy consumption. You can check out how many batteries you would need for a 2000 Watt & 5000W inverter here

Only one of the DIY solar generators featured above includes a battery, but in order to store all of that free solar energy, a battery is a critical component.

When looking for a solar generator battery, or multiple storage batteries in the case of larger solar setups, you’ll want to choose one that is built to last. No matter if you’re powering an RV or cabin, the battery is what provides the lasting energy.

The two most popular and types of deep cycle batteries available today are made with Lead Acid and Lithium Ion technology. When it comes down to it, both options are effective, but Lithium Ion batteries being are generally more efficient, long lasting, and costly.

Why use a DIY Solar Generator?

For those who are still on the fence when it comes to the benefits of DIY solar generators, we’ve compiled a list of the major advantages DIY solar generators have to offer.

Gas Generator vs Solar


Why choose a solar generator instead of a gas generator? First of all solar generators are not only better for the environment, but also eliminate the health and safety concerns that come along with gas generators.

These safety concerns include hazardous fumes and fire danger. On the other hand, solar generators can be safely used indoors.

Additionally, solar generators are environmentally friendly and use 100% renewable energy. Due to that fact, solar generators end up saving you money in the long run and can function completely off-grid without the need for continuous fill up or regular maintenance.

Cost comparison

reduced cost

One of the most appealing aspects of solar generators is their ability to pay for themselves in a short amount of time. Other types of generators, such as gas powered models, require a large initial investment as well as a continued investment in fuel and potential maintenance or repair.

Once all the required components of a solar generator kit have been purchased, there is no additional cost to run the generator. Using readily available and free solar energy, you’ll quickly recoup your initial investment with all your energy savings.

Built to Last

Another great thing about DIY solar generators is their durability. As you can probably tell by the long warranties, the materials used to make both the solar panels and additional accessories are superior quality.

The solar panels included in these DIY solar generator kits are meant to provide decades of power with minimal issues. You can expect your solar panels to last anywhere from 25-30+ years. DIY solar generators are a smart investment when planning for the future.

DIY Generator Provides More Power

By purchasing a ready-made generator you are limiting your total power output to the capacity of that specific generator. DIY solar generators don’t have set limits, so you can choose the exact amount of power you need for your own circumstances.

The kits on our list all provide a solid base to start with, but additional power can easily be achieved.

Customize To Your Liking

One of the best parts of DIY solar generators is their customizable nature. You won’t be stuck with a solar generator system made entirely from stock parts. Your choice of batteries, inverters, solar panels, charge controllers, and even brackets and cables, comes down to personal preference.

The customization aspect lets you fine tune your DIY solar generator to function the way you want and power everything you need.

Ability to Expand & Upgrade

No one wants to be stuck with a generator that doesn’t provide them with the energy they require. Luckily DIY solar generators don’t have that problem. Once you decide to tackle a DIY solar project, you’ll become more familiar with the internal workings of the system.

This knowledge will help in the case of needed repairs or when the time comes for an upgrade. Seeing as you aren't tied down to any specific equipment, you can upgrade your batteries, panels, etc., as your energy consumption changes over time.

Huge Savings over Buying Stock

There are several integral parts of a solar generator. DIY solar generators allow you the freedom to hand-select the brand and model that works best with your setup.

You can search for the best deals, many of which have been included in our list, instead of going all in on a non-customizable and often expensive stock option. Having the option to pick and choose can lead to sizable savings.

How to Put Together DIY Solar Generator

DIY solar generators are relatively simple to piece together and install. Here is a brief description so you can have a general understanding of the process. When putting together your own solar generator always refer to the instruction manuals.

  • First, your solar panel or panels should be mounted in an area with unobstructed and adequate access to the sun.
  • The second step is to wire the solar panels to the charge controller in order to regulate the transfer of power to the battery.
  • The next step is to connect your charge controller to your battery so that the collected solar energy can be stored.
  • Finally, connect your battery to your inverter to allow the DC current to be converted to usable AC current.

Now you’re ready to plug in all of your devices and enjoy your new DIY solar generator. For a more detailed look at the installation process, check out this guide on how to build a solar generator.
