*Prices are shown after applying the 30% federal tax credit.
As of Mar 2024, the average cost of solar panels in Marydel is $2.73 per watt making a typical 6000 watt (6 kW) solar system $11,456 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 about 6 months of research and about 8 quotes collected, I finally settled on Lumina solar for my home solar project. With so many door-to-door pushy salespeople coming by with bad info, it was great to chat with the reps at Lumina (Gabriel was awesome) who were super knowledgeable and provided me with honest information and a great quote. Once I signed the contract for my 33 panel installation, Lumina was right there every step of the way. They kept me in the loop on all details around permitting, and did a thorough roof/attic inspection before anything started. When install day arrived, the crew got right to work, and did an amazing job, finishing the work in one day. The master electrician was very accommodating, and was able to land the inside breaker near my panel and out of sight. The whole crew was very professional and did a full cleanup before they left. I received PTO about a month after install, and was able to energize the system myself using the clear instructions from Lumina. Its been operating perfectly since day 1, and could not be happier with the overall process and service from Lumina. Highly recommend Lumina, they exceeded my expectations and continue to be available for any questions I have.

SEW did a great job in solar installation right from the initial consulting to the final installation. They were very responsive, willing to work with the clients on their specific needs, customization, etc. My solar advisor/rep was Katie and she is absolutely fantastic and did a perfect job in the right communication throughout this process. Katie took her time to explain the entire process and was regularly in touch with us till the installation was completed. We were probably one of the tougher customers to deal with and so we really appreciate all the patience and cooperation that Katie and SEW team showed. The installation crew was also very professional in their job. No issues at all. After the installation, we realized that our consumption meter was not properly activated. SEW responded very quickly to connect us with their service team to fix this. It speaks for their value of the customer even after the installation is completed!!! Highly recommend SEW for solar installation!!

Very professional and efficient installation. 12 panels on the garage, 14 more above the attic. All work completed in one day - started at 9 AM, completed by 4:15 PM. We couldn’t be happier with Green Street.

We had CMI install our solar system several years ago and were very happy with the work and the system. Earlier this year we asked them to help us with a generator hookup. We had no problems until several weeks ago. We contacted CMI and they were able to correct the problem. We definately appreciate the overall quality of their install and their willingness to stand by their work to resolve any issues.

No issues from technical side, but after-sales customer support is not professional. Our Zantrex/Snider box stopped inverting during real-life grid outages. Standard Solar sent a technician who couldn't find or fix the problem, but sent $760 bill without explanation or warning. We had to deal with Snider on our own, and Standard Solar had problem to find proof of purchase. When they send technician to the house, they charge $92/hour, including transportation, on-site downloading manufacturer's instructions, etc. Not the level of service one would expect.

What a great experience working with Clean Energy USA on my residential install. I would highly recommend this team to anyone looking to install solar. Everyone at Clean Energy USA was a pleasure to interact with and highly knowledgeable. As a new customer to solar I could not be more appreciative of the efficient and smooth process from sales, back office and intstallation.

SunnyMac did have an attractive offer, as I was directed to them by using the EnergyPal service. My EnergyPal advisor pushed to have proceed with a Site Survey to continue moving forward, while waiting for Tesla to come out and take a look. During this period, we had five companies out to take a look and give us quotes (none of them with a fee - more on this below). With SunnyMac however, they sent over an agreement for a "deposit," which did not say nonrefundable, which was due for the site survey. I spoke with my EnergyPal advisor, Caleb Siu who told me the deposit was only owed, if I had SunnyMac submit permits on my behalf, so I agreed to the site visit. Well, my advisor was wrong. I am now receiving $1250 invoices from SunnyMac for the site survey and for "designing" my system, although I had to tell them exactly where to put all of the panels (based on other companies visits), as their proposed designs (poor computer generated models) were terrible and would have been terribly inefficient. Anyway, do not have anyone come to your home from SunnyMac unless you are 100% certain you are going to go with them, or they will send you a trumped up bill and threaten collections.

I have a solar panel system that was installed by wanex and it has rodent damage that was found by Sun power. The technician from Sun Power told me that I would not have had this damage had I been given the option of having a rodent guard system installed at the time of the installation. I at now at a loss of over $5000.00 over negligence on the contractors part. I had also asked the contractor to split the install on my garage roof because of the weight of the panels (over 40lbs.) each and since they did not listen to me at the time of the install my garage which is sitting on stone has since sunk into the ground on the side the panels are installed on and continues to sink. At this point we do not know what to do because these damages are not covered by homeowners insurance.

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 Marydel 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 Marydel.
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.
