*Prices are shown after applying the 30% federal tax credit.
As of Apr 2024, the average cost of solar panels in Baltimore is $2.3 per watt making a typical 6000 watt (6 kW) solar system $9,661 after claiming the 30% federal solar tax credit now available.
This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt.
The size of a solar panel system also plays a role in how much the installation will cost.
Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

After our AEP bill kept increasing monthly, we decided to go solar! We used Gold Path Solar in Dublin, Ohio. What we liked about this company, you are not just speaking with a salesman, but the actual owner, Jake Trubiano. He is super knowledgeable and clearly explained the process from start to finish. Communication was top notch via phone, email, and text. So glad we decided to make the jump to solar. Highly recommend this team.

Ecohouse Solar installed our 8.4 kW system in July of 2022 which included a new electrical service panel. Mike Hopper was excellent to work with and answered all of our (many) questions. He helped us design the best system with the right panels for us, at a great price. After signing the contract, Mike continued to keep us informed of all activities. Both the local and utility permitting/inspections were handled with little to no effort from us. All the installers and electricians were courteous and professional. They worked quickly without disrupting the yard or interior of the house. I would gladly recommend Ecohouse for anyone considering solar.

We had a 30 panel system installed by Third Sun. They did a good job and the system has worked well. Last year one of the panels went bad and we contacted them about the warranty. The panels are from LG. . We were told when we contracted with Third Sun that if there was a warranty issue, we could go through them. When I reminded them of this they said they would look into it only to send an email a few days later saying they could not get in touch with LG. They basically said that it was our responsibility to contact LG but would not even supply any information about how to do that. The next issue has come up recently. When we purchased the panels we specifically asked what the cost would be for them to remove and replace the panels if we had to have the roof replaced. They told us that is would cost around $4,000. We are now having that done, so I contacted them and the price they now give me for removing and replacing the panels is over $19,000. Even given inflation this is outrageous. After the government tax rebates that is only a few thousand less than the original cost of the whole project and I suspect that we could put an entirely new system in for not much more than that. The message is beware of this new incarnation of Third Sun. Whatever integrity the original company had is apparently gone, so do not expect any help or service from them after installation. We are not only committed to solar but also in another area of the solar business, so we are well informed about costs. Kokosing is not a company with which we would advise doing business.

They updated my electrical box for the solar panel install. The electrician under size range breaker and was called out by inspector. They have sent an electrician out twice to replace this breaker, and both times, no work was completed. I also have a 240v air compressor circuit that has each leg wired to 2 completely separate breakers on different ends of the main panel as this is not a functioning 240v circuit and yet an electrician shows up and reports no work needed to be done. Everything about their response is wrong. For starters, after each electrician visit, there has never been an email stating why no work has been done and won't be able to provide proof of emails sent. 2nd, as an incompetent company, they refused to address the issue verbally they wired my 240v circuit for the air compressor wrong. Their electrician stated they can run new wire to our stove or replace or oven with a 30 amp stove. This is a company that can't honor what their employees are promising and need to get the hell out the way so honorable companies can do right by their customers paying $78k for a job. This place is clearly ran by someone with zero integrity as I have received responses that are flat out lies

I had a 19 panel system installed last week. I’m overall very satisfied with SIF on pricing, quality of equipment, and quality of install. The only area that I wish was a little better is their communication. During my 3 month install process, I called the office 3 times. I never had anyone answer the phone when I called, but they did call me or text me back within 24 hours. Ultimately, no major issue, but hope they improve this going forward. If/when I move, I would be happy to have SIF install a system on my next home.

We hired Bold Alternatives to do a 3KW array on our house (no storage). They pulled all permits and passed inspection the first time. The array looks beautiful. They worked with a roofer who seems to have done a good job with our cedar shingle roof. Overall a highly recommended company.

I had several estimates for my solar project and ended up with Yellowlite. They were very informative and prompt on answering any questions anytime. Also wanted to stay with a local business. So many other solar companies are not even based in my area. Yellowlite is the way to go and will be referred. Thank You Yellowlite for making this project carefree of any issues from day one to the finish line.

ARP - The best Solar system out , over 1 month
I am not sure where to start. I saw a huge difference in the various installers out there. ARP-Solar is EXCELLENT. I looked seriously at four different providers and Gary Easton at ARP-Solar was by far the best; best design, most knowledgeable about the products in the industry and the industry in general, fastest response time to questions, best references, and yes, the best price. His installation team was very pleasant to work with and top notch. They even re-stacked my fire wood next to where they installed one of the disconnect boxes. I can’t wait to tell everyone in my network about them. The only issues I really had all were dealing with Duke Energy and getting the bi-directional meter in. We had issues with them reading it correctly and entering the data correctly. It should be fixed now – my last Duke energy bill was $5.36 for November. I still need to find a way to keep the snow and ice off the panels and to clear out these clouds! I can’t wait to see my production numbers this coming spring and summer!

We had a good experience with Johnathan and his team at Modern Energy, they are very profesional. Also, we are very pleased with the way they handled all the permits with German Village commission and the city. Thank you to Modern Energy we became the first house in German Village with solar panels!

The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.
We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!
The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.
These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:
Homes that use more electricity will need more solar panels to cover their energy needs.
Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.
But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.
The price of solar panels can vary depending on the type of solar panels you choose.
There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.
The type of inverter you buy will also influence the cost of your solar system.
You may see some solar quotes with prices that seem too good to be true.
If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!
It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.
The overall cost of solar can be influenced by the solar incentives available.
Across the U.S., homeowners can apply for the federal solar tax credit. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 30% of the cost of their installed solar panel system.
Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.
See what solar incentives are available in your area by using our solar panel calculator.
The cost of installing residential solar panels in Baltimore varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in Baltimore.
As you can see the payback period is relatively short and equates to a much better return on investment than he historical returns that have been available from investing in things like shares or property.
