Investing in renewable energy helps you reduce your environmental impact while saving money on your electricity bills. If you want to take a small step toward using solar energy, or if you want to extend the solar power you’re already using, a do-it-yourself (DIY) solar panel kit could be a good way to avoid professional installation labor costs and take advantage of solar power.

Note that DIY solar panels are meant to power smaller spaces, such as sheds or poolhouses. They’re not meant to power your entire house. If you’re interested in a solar panel system for your home, take a look at our guide to the best solar panel companies

 


 

What Are DIY Solar Panels?

DIY solar panels come in the form of a solar kit that includes the basic materials you need to set up a solar energy system yourself. These are meant for small-scale applications and are not recommended to power your entire home. Most aren’t made to be connected to the power grid. They’re best for off-grid solar use, such as powering a detached workshop, a small guest house, or even an RV. If your system doesn’t generate enough electricity to fully power these spaces for a day or two due to overcast conditions, it won’t be a big deal. 

What’s in a DIY Solar Panel Kit?

Most solar panel kits include the following items:

You need to buy cables and mounting hardware separately if your kit doesn’t include them. Kits typically don’t include tools you’ll need for assembly and installation. Also note that kits come in different sizes. You can get kits with varying numbers of solar panels and battery backups, depending on how much energy and backup power you need.

DIY Solar Panels Cost

One of the biggest reasons people choose to install solar panels on their own is that it saves money on the labor costs of hiring a professional solar installation company. According to EnergySage, solar kits from popular brands such as Grape Solar, Renogy Solar, and Eco-Worthy cost in the range of $575 to $875 for a 400–600-watt system size. Kits range between $1,000 and $1,350 for an 800-watt system size.

Installation typically accounts for around 10% of the total cost of a solar system. That said, the amount of money you save by skipping professional installation will likely be minimal. You may find that any money saved isn’t worth it overall. 

It’s also important to note that installing solar panels yourself often disqualifies you from solar incentives that can help you save money through solar tax credits and exemptions. Incentives and rebates, such as net metering, are usually reserved for larger system sizes and professional installations.

 


 

Professional vs. DIY Solar Panel Installation

A DIY solar installation lets you control the process and timeline while eliminating labor costs. However, you must factor in the cost of any tools your kit requires. More importantly, installing solar panels requires assembly skills and an understanding of your energy needs and how to run cables to power your space.

Since professional installers already have this expertise and the necessary tools, many find it easier to have a pro do the job, especially since labor is only a fraction of the cost of going solar. A professional solar company is licensed, so you can get solar incentives to help you save money. Professionals handle most of the paperwork needed to get a permit for the installation, and licensed installation means you’ll get a labor warranty if you have any issues with your system. Since your system may require repair or maintenance, not having a warranty is one of the biggest cons of DIY solar projects.

 


 

Factors to Consider Before Installing DIY Solar Panels

Before purchasing a solar kit, there are a few things DIYers should consider:

 


 

Our Recommendation

A DIY solar system might be a good option for you as long as you understand you won’t get a warranty or solar incentives. Make sure you have expertise in solar power systems, understand the capabilities of an off-grid system, and are comfortable with the time it takes to install. If you prefer to be grid-tied or to have warranty coverage and help with permitting, we recommend spending a little extra for expert installation. You’ll likely save money and time in the long run and won’t have to deal with the headache of troubleshooting if you run into issues during installation.
