How to Build Your Own DIY Solar Generator

Solar energy is no more a futuristic concept. People choose to go solar for a variety of reasons. Some people desire to convert to clean, renewable energy. Others prefer the concept of minimizing their reliance on the power grid.

However, the most crucial reason to go solar is to save money. According to a Pew survey, 96 percent of those who have installed or want to install solar do so to save money on their power bills, which is higher than any other reason given.

It is now entirely possible to achieve significant savings by working with a professional solar business–after all, that is how the majority of customers go solar. However, if you want to keep your upfront costs as low as possible, you might choose a do-it-yourself (DIY) installation.

For less than $300, you may build a DIY solar generator in your own home (or wherever you want it). There must be some snag. Nothing, unfortunately. All you have to do is put together the generator, which you can do yourself.

There are only a few alternative energy sources that don’t pollute or have any adverse environmental repercussions, and solar energy is one of those options. People using solar energy, which is a big step toward turning our planet green again save annually 75 million barrels of crude oil.

Although environmentally benign and practical cost, solar energy is also highly convenient due to its accessibility anywhere and time of use. Make your own portable mini-power plant with a DIY solar generator that can run your gadgets and even small appliances without relying on a power source like the grid.

DIY Solar Generator: Concept and Benefits

A solar generator is a gadget that turns sunlight into power that can be used at any time by our electronic devices.

DIY stands for Do It Yourself. This entails purchasing a pre-made item that you will construct on your own. DIY allows you to choose the best components and build your device exactly to your specifications while saving you money! When you do things on your own, you end up learning a lot in the process.

There are three primary purposes for the DIY solar generator:

  • Maximize solar power generation.
  • Maintain a supply of power in reserve.
  • Use solar power to generate usable electricity.

It’s lightweight, plug-and-play, long-lasting, and doesn’t require any special care or maintenance. It is also expandable in terms of both power and size.

What Are the Benefits of Building Your Own DIY Solar Generator?

Solar and wind power are the best options if you want to run your house, RV, hunting lodge, or other electrical systems and equipment safely and environmentally friendly. Solar power, in particular, is a low-cost renewable energy option that can be built and used quickly.

And because they are powered by solar energy, we can use these generators all year round, indoors or out. In the event of a fire or leak surrounding the generator caused by fossil fuels, your family and pets are more likely to be injured or killed.

While a solar generator won’t charge instantaneously, it normally takes 12 hours or fewer for it to be fully charged with a solar generator. Making your own, on the other hand, can result in a significant increase in charging time. That means you’ll have instant access to the power you need in an emergency, for everyday tasks around the house or RV, or for whatever else you need it for.

Your expenses will be virtually eliminated as soon as you get a solar generator. Because the generators and solar panels are meant to endure for decades—most have 20-year warranties–the upkeep is minimal. You should inspect your solar panels after inclement weather, clean them twice a year, and make sure that nothing is blocking the sunlight from reaching the photovoltaic cells. If not, you’ll need to put together a generator and solar panels before you can leave.

Even if they are the least expensive and easiest to maintain, regular generators may not be the most reliable. However, if you built your own solar generator from the ground up, you’ll be prepared to replace any broken components. This results in even greater financial savings for you.

Ready-made solar generators are available that are powerful enough to meet your requirements. However, if you want to power your entire residence, have larger energy requirements than the “typical” RV owner, or simply require more juice, a kit may not be sufficient. If you do it yourself, you’ll know exactly how much electricity your generator and set-up produce.

When you build your own solar generator, you not only learn a lot about new technology but you’re also rewarded with a great deal of satisfaction. This solar generator was developed by you, not some random shopkeeper. Also in contrast to purchasing a large generator all at once, you can save money by putting together the necessary components yourself.

Components and Parts

To begin, locate all of the elements and components that will go into your solar generator.

Rugged Case

You need a watertight, weatherproof, and most all, strong case to store the device’s most important components. The Pelican 1620 Case, which has numerous tough handles and rolling wheels, is a wonderful option. A huge DeWalt Tool Box can also be used to make solar generators portable.

AC solar power inverter

To convert DC voltage from your batteries to AC voltage for your appliances, utilize an AC solar inverter (also known as an ac-to-dc converter). The Renogy 2000W Pure Sine Wave Inverter offers a surge power of 4000W and overload protection for both the DC input and the AC output.

Solar Panel

The solar panel collects energy from the sun and feeds it into the battery. As one of the solar generator’s most visible components, your panel must be both high-quality and long-lasting. This Jackery SolarSaga 100 Watt Solar Panel, which is both tough and light, comes highly recommended by me. It’s lightweight and folds up small enough to take with you when you travel, and it works great with your generator anywhere you decide to pitch a tent.


In order for your generator to use solar energy, it has to have a battery. Lithium-ion or deep-cycle lead-acid batteries are your best bets out of all the battery types. The following are the benefits of both methods:


  • Highly effective (up to 98%)
  • Lightweight and compact in design
  • The battery can be partially recharged without suffering any long-term damage.
  • Most products come with a 10-year warranty.
  • a 12V Renogy Lithium Iron Phosphate Battery

A lead-acid battery with a long cycle life

  • Time-tested innovation
  • Life expectancy is up to 15 years in some cases.
  • Recyclable materials
  • The battery life is significantly increased with a small charge.

Not all batteries and inverters are the same. And the Goal Zero brand is an alternative that outperforms the competition. The Goal Zero Sherpa 50+, in particular, is a superb inverter option that is compatible with most systems and is guaranteed to endure for years.

The battery is a DIY solar generator lithium battery pack with 50 watt-hours of capacity and several connectors, including USB ports, laptop ports, and a conventional AC electrical outlet. The battery includes an easy-to-read display that also shows how much juice is remaining in the battery.

The Mighty Max ML35-12 battery is another reliable option for your DIY solar kit. This sealed lead acid battery is made to last and will provide hours of power storage for your equipment. It is a spill-proof SLA AGM battery with a high discharge rate, a wide operating temperature range, and a long service life.

Solar charge controller

The solar charge controller regulates the voltage and current levels coming from the solar panel to prevent overcharging your battery. Choose a solar charge controller with a moisture-tight coating if you’re constructing a portable solar generator.

Battery maintainer 

A battery maintainer is a small battery charger that gives a small quantity of electricity to your battery when it is dormant for a long time. You should make use of it to extend the battery’s life.

AC power inlet 

The hard case’s external ac-in power supply inlet. Opt for a power outlet with a built-in 18-inch extension cord that does not require any cable changes or hand wiring.

LED floodlights 

Equip your generator with bright and dependable LED floodlights so you can utilize them as a light source around your campsite, boat, or home during a power outage.


Choose the right solar system type 

Choosing the proper type of solar power system is the next step. The components in all solar generators have a lot in common: solar panels, inverters, mounting hardware, and wiring. However, there are some significant variances that may have an effect on the project’s cost and complexity. Here’s a quick rundown of what each one is about.

  • A grid-tied solar panel system makes use of the grid as a battery via net metering. Due to the lower upfront equipment requirements, grid-connected solar systems are the most cost-effective option. These systems have the drawback of being completely self-sufficient.
  • A battery storage option is included in a hybrid solar panel system, but the system remains connected to the utility grid. In comparison to grid-tied systems, hybrids are more expensive, but they provide additional capabilities like backup power in the event of a grid failure and flexibility in terms of when energy is used.
  • Off-grid solar system: Off-grid solar generators don’t rely on the grid for power. Without a grid to fall back on, a huge battery bank and a lot of solar panels are needed to power a house 24/7/365, even in winter and/or during long periods of gloomy weather. As the name implies, this system is the most expensive.

Instructions for Making a Do-It-Yourself Solar Generator

While the other people do an excellent job of providing detailed directions, I believe a brief explanation of the main procedures for making your own off-the-grid solar charger would be useful right now. This should give you a good understanding of what you’re getting yourself into, allowing you to make an informed decision on how to proceed from here.

Determine Your Energy Requirements

If you’re building the solar generator for home usage, check your energy bill. Alternatively, you can look at a chart that shows how much energy the various devices you use require to run. This will assist you in determining the load required for your system.

  • 10-50W ceiling fan
  • 15W DVD Player
  • 5W CB Radio
  • 7W modem
  • 25-100W for laptops
  • 250W Drill (1/4 inch)
  • 1200W Toaster Oven
  • 15W Blu-ray Player
  • Recharging a tablet takes 8W.
  • 30W Satellite Dish
  • 35W Cable Box
  • LCD TV: 150W
  • 10W LED light bulb (40-watt equivalent)
  • 100W LCD Monitor
  • 6W Smart Phone Charger
  • 1000W Coffee Maker
  • 1200W fridge (16 cubic feet)

If you’re wondering how to create a 5000-watt solar generator, make sure to use components that can withstand such a load.

Make a Well-Thought-Out Selection of Your Materials

Check the ratings, wattage, and other information given in the more detailed guides before making any purchases to ensure that you have the correct parts for your project. You don’t want to waste your time, money, or energy on something that won’t work the first time around.

Perform a Parts Check

Your system must be tested before you begin construction. Some of the instructions above go into great depth about how to do this safely and accurately.

Install All of Your Hardware and Software.

You’ll have to mount your 100-watt solar panels, but you’ll also have to construct or locate your battery bank. Now is the time to carefully review your solar generator plans to make sure there are no surprises later on.

Connect everything with wires

The next step is to safely connect all of your components together. 

Connect All of Your Electronic Devices

You should be able to plug in your devices and start using solar energy once your kit is assembled and everything has been tested.

Look into the rules and regulations relating to solar power

Solar generators are governed by a complex set of laws. States, and even municipalities, have vastly different laws. Some states only allow a licensed contractor to install a solar system before it can be linked to the grid. If this is the case in your area, you will be unable to set up a DIY grid-tied or hybrid solar system.

If you’re doing the installation yourself, you’ll need building permission and a utility permit first, even if it’s legal to do so. A structural engineer or a certified electrician will conduct an onsite examination as part of this process. Once the installation is complete, you’ll have to go through another series of inspections before your system can be activated and/or linked to the grid. 

Things to keep in mind!

Going solar has significant financial advantages: it lowers your monthly electricity bills and can even raise the value of your home. Solar incentives, such as the federal tax credit, can cut your net cost by 26 percent, but solar is still a large investment, and the price tag can cause sticker shock. It’s no surprise that many homeowners are considering DIY projects to save money.

According to EnergySage Solar Marketplace data, the average gross cost of going solar for homeowners is $16,860 (costs before incentives and rebates are applied). Design and installation labor costs account for approximately ten percent of the overall bill — this ten percent is what handmade solar panels will save you in essence, as you will still have to purchase the equipment yourself. Regardless, it is tempting to consider creating your own solar panel installation in order to save money and have complete control over your project. 

Consider the Expenses

As your solar energy system should provide electricity for the next 25 to 35 years, it’s critical that you analyze both the upfront expenses and the relative financial benefits of all of your solar options. 

When deciding to build your own solar panels, keep in mind that you get what you pay for. Although a residential solar kit is less expensive, solar professionals provide enormous value for a relatively small additional cost. Finding someone who knows what they’re doing when it comes to building an expensive electrical system in your house might actually save you both time and money in the long run.

Self-installation process

Self-installation of solar panels can be rewarding, but only if you’re looking for a real DIY project to get your teeth into. If, on the other hand, your previous DIY knowledge is limited to putting together flat-pack furniture from Scandinavia, you might want to avoid taking on solar. It’s a time-consuming undertaking that necessitates a great deal of preparation and organization. A DIY solar installation can take anywhere from one to four months to complete.

If your roof isn’t flat, you’ll have to drill a lot of holes in it to install solar panels. Incorrect drilling can harm the roof’s structure, while improper sealing and flashing can lead to leaks and/or mold growth. Another thing to consider is that if you do your solar installation, the guarantee on your roof will be voided, and you’ll be responsible for paying for any necessary repairs.

When performing a solar installation on their own, homeowners run the risk of serious injury or death due to heights and exposure to high voltage electricity. And the dangers do not end after the installation is complete.

If the panel malfunction over its 25-year lifespan, you’ll be responsible for going back up on the roof to fix the problem. Most dangerously, your rooftop system could catch fire if the wiring isn’t connected properly! If something goes wrong with the equipment, you’re on your own to fix it. You can, of course, contact the manufacturer directly, but proving a warranty claim might be challenging. The warranty may also be voided if an improper installation was performed.

Incentives provided by state

Many states provide rebates and incentives to lower the cost of going solar. On the other hand, some incentives are only accessible if the installation is done by a qualified solar firm. Check to see if there are any incentives or rebates available in your area.

If you’ve been considering going solar, there’s no better time than now. Government financial incentives are still available, the cost of photovoltaic (PV) cells is reducing by the day, and you’ll most likely be the first person on your street to make the switch.

Adding solar generator to your home is a great endeavor for a number of reasons: You’ll save a lot of money on energy and may even be able to sell part of it back to the utility company; you’ll lessen your carbon footprint; and if you’re installing in a remote place (like a cabin), you’ll have a lot less to worry about than if you used a gasoline generator. You’ll also be supporting a burgeoning industry and, as a result, contributing to the global adoption of this fantastic alternative energy source.

We hope you found this information useful and instructive. Home solar generator isn’t very complicated, and with government subsidies, it’s also not overly expensive. In the long term, you can save a significant amount of money on your energy costs and even profit by selling power back to the utility provider.

Once you understand the components of a solar array, the entire procedure becomes considerably less daunting; it’s simply a matter of modifying the formula to your individual situation. Thank you for taking the time to read this, and good luck with your solar project!
