Solar panels are an appealing way to make your home more eco-friendly and reduce your monthly energy bills. However, they’re expensive to install, with a large portion of the cost going toward labor. Do-it-yourself (DIY) solar panels have become increasingly popular as a result, but this is a complex project that requires knowledge and skill. In fact, we surveyed 1,000 homeowners and found that less than 0.3% chose to install their panels themselves.

We’ve spent more than 770 hours researching the best solar panels available, including DIY solar kits. Our guide explains what a DIY solar panel project entails and explores whether it’s worth the money you save, compared to the return on investment for standard solar systems.


Pros and Cons of DIY Solar Panel Installation

Pros

  • Helps you save money on solar panel installation
  • Gives you more control over the installation process
  • Lets you design your own solar power system

Cons

  • Requires a lot of expertise, and mistakes can lead to roof leaks or damage
  • Is a highly time-consuming project
  • Isn’t backed by a warranty

Solar Panel Cost

One of the primary appeals of DIY solar panels is that you can save money. According to EnergySage, solar panels cost an average of $29,410 for a 10-kilowatt (kW) system. Roughly half of that cost goes toward labor, overhead, margin, customer acquisition, and other costs that do not apply to a DIY solar power installation. Your overall cost for DIY solar depends on factors like where you live and whether or not you need solar batteries along with a charge controller that manages them. Many customers save $5,000 or more on DIY solar panels compared to the cost of professional solar installers.

However, professionally installed solar panels come with a few benefits that can help offset the higher price:

  • Wholesale discounts: Professional installers get better deals on solar panels and other equipment. You will likely pay more for the same components if you buy them yourself.
  • Financing: Many solar companies offer financing options to make your project more affordable. Getting a loan for a DIY project will be significantly harder, so you may have to pay the full cost upfront.
  • Warranties: Professionally installed solar panels typically come with a warranty from both the manufacturer and the installer. These warranties can save you money if something goes wrong with your system in the future.
    Tax incentives:
  • Peace of mind: An experienced installer can maximize the reliability and efficiency of your solar system. For most homeowners, that extra assurance justifies the higher cost.
  • Convenience: Installing your own solar panels requires a significant time investment. Professional installation costs more but saves you time, hassle, and risk.
  • Tax incentives: Federal and state governments, utility companies, and municipalities offer a variety of incentives to lower solar installation costs. However, DIY installations may not qualify for many of them.

Quick Tip

  • Find out which tax credits, cash rebates, Solar Renewable Energy Credits (SRECs), and property tax exemptions apply to DIY installations. One example is the federal solar tax credit, which provides a tax reduction equal to 30% of your DIY solar panel system installation costs. If your tax liability is lower than the deduction, it will roll over to the following year. If your utility company offers net metering, which allows grid-tied solar homeowners to sell excess energy back to their utility company, DIY solar installations can take advantage of that too.

Sunrun

4.5

We like Sunrun for its four financing options, including its unique leasing options if you don’t want to own your system. This stands out to us because the other companies on this list don’t offer as many options.

Prepaid and leased systems also include a 25-year warranty with system service and maintenance, ongoing monitoring, and theft insurance. The company even offers financing plans for quality monocrystalline solar panels and products from trusted brands such as LG.

How We Scored Sunrun

Its accolades include Best CEOs for Diversity 2022, Best Company Culture 2021, and Best Company for Women two years in a row.

Sunrun currently holds an A+ rating from the BBB and is accredited. Former customers praised the comprehensive coverage for leased systems but complained about delayed installations, poor customer service, and poor communication with project managers. Additionally, some customers note being confused by Sunrun’s leasing and PPA options, though they also mention Sunrun is willing to discuss and clarify these plans.


Solar Panel Installation

It’s possible to install solar panels on your own, but DIY solar installation requires serious know-how and tools. Some solar companies design solar panel kits targeted toward DIYers. However, these kits are often meant for small builds, such as converting a shed, RV, or boat. 

Installing a solar energy system requires knowledge of electrician work. You’ll have to work on your roof and with buried wires. The stakes are high for a mishap; crossed wires can malfunction and even cause electrical fires. Additionally, it may be illegal for you to do this work without a professional, depending on your municipality’s zoning laws. Many zoning laws also prohibit installing off-grid solar energy systems. 

DIY solar panels work best for small projects or to supplement a traditional energy source. If you want to power your home with solar, we recommend hiring one of the top solar companies to design and install your system.


Solar Panel Maintenance

Professional solar companies include a warranty with an installation that protects your investment if there’s a malfunction or installation error. They’ll complete repairs or replacements if necessary and may even cover the cost.

DIY solar panel installation doesn’t come with this support. However, once the solar system is set up, regular maintenance is low. Solar panels require cleaning every few months, which can be done by rinsing them with a garden hose. If you lack the technical expertise to identify issues with solar panels, hiring a professional to inspect your panels once each year is a good idea. Similarly, if your solar panels are damaged and require repairs beyond your technical ability, you will need to hire a professional to resolve the issue.


How To Find the Best Solar Panels

You’ll need to consider many factors when selecting the best solar panels for your project, including the panel type, efficiency rate, and warranties. We’ll go over each of these factors in more detail below. A solar panel manufacturer can help you with your selection, but hiring an installer is the best way to ensure you get the right panels for your project. Racks and roof mounts to place your solar panels on and an inverter to convert solar energy into alternating current may also be necessary.

“If you work with a turn-key installer that communicates at each step of the process, the home solar installation should be easy and worry-free,” says Matt Johnson, co-owner of Namaste Solar. “A seasoned installer should handle all the logistics from design to permitting to finding all the incentives and rebates available.”


Solar Panel Types

Knowing the different types of solar panels available can help you narrow down your options.

Monocrystalline

Solar panels are the most popular. They’re the most efficient and have a simple, low-profile design ideal panels for residential homes. Monocrystalline panels are created from pure silicon and come in two different variations: passivated emitter and rear contact (PERC) and bifacial. PERC panels have a conductive layer added to the backside of cells to increase energy absorption. PERC panels are most commonly used in rooftop solar systems. Monocrystalline solar panels are the most popular. They’re the most efficient and have a simple, low-profile design ideal for residential homes. Monocrystalline, or mono, panels are created from pure silicon and come in two different variations: passivated emitter and rear contact (PERC) and bifacial. PERC panels have a conductive layer added to the backside of cells to increase energy absorption. PERC panels are most commonly used in rooftop solar systems.

Bifacial

Bifacial panels absorb light on both sides at a higher rate than PERC panels. For this reason, they’re typically reserved for ground-mount systems that expose both sides of the panels.

Polycrystalline

Polycrystalline solar panels use older technology than mono panels and are a cheaper option. However, these panels are less efficient than monocrystalline offerings and, in turn, require more panels to power your home.

Thin-film

Thin-film panels are the standard for small DIY solar panel kits. They’re also among the cheapest solar panel options. The manufacturing process for these panels is less complicated, so they take little time to make. They’re also the least efficient panel type, but they have practical uses. Small DIY solar projects, such as RVs and small off-grid systems, use thin-film solar panels.

Efficiency

Solar panel efficiency is vital to your solar energy system’s performance. A higher efficiency indicates that the solar panel can convert a larger percentage of sunlight throughout the day. The more sunlight that gets converted, the more power your system generates to run your home. The National Renewable Energy Laboratory (NREL) says solar panels typically fall between 16% and 22% efficiency. The most efficient panels cost the most, but they can be worth it because they’ll save you money on your electric bills in the long term.

Warranty

Standard solar panel warranties cover the product and its performance. Some companies provide comprehensive warranties that cover both the product and its performance in one contract. However, warranty coverage for DIY solar panels is limited since you’re taking on the installation yourself.

A standard product warranty lasts for 10–12 years. Some companies offer extended warranties for 25 or more years. Other companies only offer extended product warranties if you use one of their authorized dealers or installers. 

The standard performance warranty guarantees 90% production for 10 years and 80% through year 25. Some premium solar panels guarantee 90% or higher output for 25 years. These warranties typically include coverage for any dips in performance as well. If your solar panels are not performing to the standards outlined in your warranty, the solar installer will send you the required parts for free repair or upgrade.

The video below offers an overview of common factors you should consider when shopping for DIY solar panel kits: 


Our Conclusion

DIY solar panel installation is possible if you feel comfortable dealing with the issues outlined in this guide, but we only recommend it for small projects. Solar panel installation is complicated and can be dangerous, so you may prefer working with an installer. A professional can help you determine the correct number of panels for your project based on your budget and energy needs. If you do decide to install panels yourself, make sure to do your research and take the proper safety precautions.

FAQ About DIY Solar Panels

Are DIY solar panels worth it?

DIY solar panels are worth it if you have the expertise and tools for the project. They might not be worth it for a full-sized home, but they work well for small projects such as converting an RV or shed.

Is it cheaper to build your own solar system?

Yes, it’s cheaper to build your own solar panel system. Since you don’t have to pay for labor and other overhead costs, you could save $5,000 or more with a DIY system. However, installing solar panels is a complicated process with many possible mistakes, and you may have less access to cost-saving solar incentives.

How many solar panels will I need to run a house?

You will need 17–25 solar panels to run a house. The exact number varies depending on your annual energy usage, the number of peak sunlight hours in your area, and the wattage of the panels.
