*before incentives
It’s important to note that everyone’s installation cost will vary. Factors such as location, how many solar panels you install, and what installation company you use will impact the total price.
How can I save money on a solar panel installation?
Through incentives, rebates, and other unconventional methods – there’s a few ways you can save some money on a solar panel installation.
Federal solar tax credit
Right now, the best incentive for going solar is the 30% federal solar tax credit, which equals 30% of installation costs and reduces what you owe in federal income taxes by thousands of dollars.
The average solar installation costs around $20,000, meaning you’ll receive a tax credit of $6,000.
Local solar rebates and incentives
Different states, municipalities, or utility companies may offer incentives for going solar that can help reduce the solar installation cost. This can come as a tax credit, an upfront rebate, or a performance-based incentive.
Local incentives are also available to those who install battery storage with their solar installation, and low-income solar programs to help qualifying households go solar.
DIY solar panels
You can install solar panels yourself to cut installation costs by purchasing a DIY solar panel kit. Saving money is always a plus, but we do not recommend DIY installations for rooftop solar.
Installing solar panels yourself is risky for most homeowners unless you have experience with construction and electrical work.
Also, some utility companies may not even allow you to interconnect your solar system to the grid unless installed by a professional installer – meaning you’ll lose out on net metering or other available utility incentives.
Installing panels yourself also risks voiding the solar panel or roofing warranty. So, you’ll save a bit of money on installation but risk a poorly installed solar system that may not be covered under any warranties. Take our advice and hire a professional to avoid any headaches.
Used solar panels
You can find cheap solar panels from private sellers online that can save you hundreds on materials. If you want to utilize solar technology, used solar panels can be a solid option for small-scale projects.
We do not recommend purchasing used solar panels on a rooftop home solar installation. Instead, consider looking into refurbished solar panels because they have been restored to an acceptable working condition. If you want the best results for residential solar, consult a professional who uses reliable solar panel brands (like the ones in this article!).
Net metering
Net metering is the utility billing practice of recording the excess energy generated by a solar panel system and applying that excess energy on the customer’s bill as a credit towards energy drawn from the grid.
In other words, if your solar system generates more energy than your home consumes, you can sell that excess energy to your utility provider instead of letting it go to waste. In turn, you save additional money on your electricity bills through these credits.
Net metering policies differ depending on where you live and your utility. To learn more about the net metering benefits you can take advantage of, visit your local utility’s website.
Compare solar quotes
Comparing solar quotes is a great way to educate yourself and help save money on your solar installation.
We recommend obtaining at least three solar quotes from local installers to compare the best price for your budget. Looking at fewer solar quotes could mean paying more for a service that another company could charge less for!
Can I finance my solar panels?
If you cannot entirely pay for your solar system out of pocket, you have the option to finance your project through a solar loan, lease, or power-purchase agreement (PPA).
Solar loan: Loans are a great way to pay for a solar installation in monthly payments rather than in one lump sum, while also saving money on your electric bills. However, financing through a loan will make your solar installation more expensive with interest rates and dealer fees.
Solar lease/PPA: Through leases and PPAs, you can install solar panels for $0 down. The solar company owns your panels for a contracted period of time, meaning the company is entitled to any incentives and rebates. By choosing these options, your savings will be less than if you were to own the solar panels directly.

Cheap solar panels: Methodology
Our solar experts analyzed top solar brands to find the brands that offer the best price without sacrificing quality or reliability.
We looked at four scoring criteria: Value, Module quality, warranty, and company financial performance.
Value (15 points): We looked at the average wholesale selling price of the panels in container volumes landed in the United States. The lower the wholesale price, the higher they scored.
Module quality (10 points): We considered each module’s specifications, including efficiency, temperature coefficient, and bonus points if the modules were listed on the PVEL scorecard. The better each panel performs, the higher the score.
Warranty (5 points): We looked at the product and performance warranties to ensure the panels recommended come protected and built to last. Panels scored higher if they had a product warranty greater than 15 years. For performance, the lower the degradation rate, the higher the score.
Company financial performance (5 points): To be sure that the manufactures we recommend are also in good standing, we reviewed the financial performance of each company. Points were awarded for revenue, revenue growth, and a positive net profit margin. A bonus point was also given to publicly traded companies, and companies with financial statements available.Cheap solar panel FAQ
Are cheap solar panels any good?
Cheap solar panels can be good quality, if you seek out the right brand. When it comes to performance and overall quality, there are plenty of solar panels out there that come at a lower price than the national average but still perform well.
If you plan on choosing a full-service installer for your solar system, you might find that sometimes the only difference between the ‘cheap’ option and the ‘industry standard’ option is only about a 5% to 10% price increase.
