How To Build A DIY Solar Generator Step By Step?

Are you tired of being tied to an electrical outlet? Do you want to have a portable power source for camping or emergencies? A portable solar generator could be the solution you're looking for. In this article, we will guide you on how to build a DIY solar generator step by step.

What Is A DIY Solar Generator?

A solar generator is a device that converts sunlight into electricity, which can be used to power various devices. A DIY portable solar generator is a homemade solar generator that you can build by yourself using affordable materials and tools. There are many different types of solar generators out there, but they all have one thing in common: they utilize the power of the sun to produce electricity. The most common type of DIY solar generator is called an off-grid system.

An off-grid system is designed to be used without an existing electrical grid or grid-tied inverter. This means that when there's no power from the utility company available, then your off-grid system will kick in and start generating electricity for you.

Benefits Of Building Your Own Portable Solar Generator:

Building your own portable solar generator has several benefits, including:


Building your own portable solar generator can be cost-effective compared to buying a commercial one. The cost of a solar generator varies depending on the quality and capacity of the components used. However, a DIY solar generator can be built using affordable materials and tools, saving you money.


When you build your own portable solar generator, you have the freedom to customize it to meet your specific needs. You can choose the size and capacity of the solar panel, deep cycle battery, and inverter based on the amount of power you need to generate.

Easy maintenance:

DIY solar generators are easy to maintain as they have fewer parts than commercial generators. With regular maintenance, a DIY solar generator can last for several years.

Environmentally friendly:

Portable solar generators produce clean energy and do not emit harmful greenhouse gases. By building a DIY solar generator, you can reduce your carbon footprint and contribute to a sustainable future.

How Do I Build My Own Solar Generator?

To build a DIY solar generator, you will need the following materials:

  • Solar panel;
  • Charge controller;
  • Deep cycle battery;
  • Inverter;
  • Battery box;
  • Wires and connectors;
  • DC circuit breaker;

Follow these steps to build your own solar generator:

Step 1: Choose the solar panel

Select a solar panel that can generate enough electricity to power your devices. A 100-watt solar panel is a good place to start.

When picking out solar panels, there are a few things to keep in mind. For example, some things you better think of as follows:

l Portable:

If you want to be able to move your solar panels from place to place, then a portable system will work best for you. For example, OUPES' portable solar panel 100W/200W has an easy-to-install bracket for easy installation and use.


l High conversion efficiency:

Solar panels with high conversion efficiency can help you save money by generating more electricity from the same amount of sunlight that falls on your roof or land.

The conversion rate of solar panels on the market is generally above 18%, and there are some better ones, such as OUPES's - its conversion rate reaches 22%! It is covered with monocrystalline silicon solar cells that convert light energy into electricity more efficiently.

l Suitable for outside use:

If you plan on using your solar panel system outdoors, then it needs to be weatherproof and durable enough.

Step 2: Choose the charge controller

A charge controller prevents overcharging of the battery. Select a charge controller that can handle the wattage of your solar panel.

Step 3: Choose the deep-cycle battery

A deep-cycle battery is designed to discharge and recharge repeatedly. Select a deep-cycle battery with enough capacity to power your devices.

Step 4: Choose the inverter

An inverter converts the DC power from the battery to AC power that can be used to power your devices. Select an inverter that can handle the wattage of your devices.

Step 5: Assemble the components

Connect the solar panel, charge controller, deep cycle battery, and inverter using wires and connectors. Install them in a battery box.

Step 6: Install the DC circuit breaker

Install a DC circuit breaker between the battery and the inverter to protect your devices from electrical surges.

Step 7: Test the solar generator

Test the portable solar generator by charging it with the solar panel and using it to power your devices.

Cost of Buying Vs. Building Your Solar-Powered Generator:

The cost of building a DIY solar generator varies depending on the quality and capacity of the components used. However, building your own solar generator is generally cheaper than buying a commercial one. A commercial portable solar generator can cost between $300 and $3000, while a DIY solar generator can cost between $150 and $500.

However, whether you buy a commercial portable solar generator or make a DIY solar generator yourself, both are also used as a more energy-efficient energy storage method. If you are confused about how to choose a solution that is more suitable for you, you can also ask more professional personnel (such as the OUPES customer service team).

Frequently Asked Questions:

l How long will a DIY portable solar generator last?

A well-maintained DIY solar generator can last for several years.

l Can a DIY solar generator power my home?

A DIY solar generator may not be powerful enough to power an entire home, but it can power small appliances and electronics. If you want a more powerful solar power station, you can buy a Mega 5 4000W solar power station as a powerful off-grid backup power supply.

l Can I add more solar panels to my DIY solar generator?

Yes, you can add more solar panels to increase the charging speed and capacity of your solar generator.


Building a DIY solar generator can be a fun and rewarding project. With a little time, effort, and money, you can create a portable power source that can be used for camping, outdoor activities, or emergencies. Remember to choose quality components and follow safety guidelines to ensure the longevity and efficiency of your portable power station.
