*Prices are shown after applying the 30% federal tax credit.
As of Apr 2024, the average cost of solar panels in Huntsville is $2.28 per watt making a typical 6000 watt (6 kW) solar system $9,584 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.

If you’re considering Solar, look no further, CKR is the one to choose. From our initial meeting with Ian, to the final inspection, the level of professionalism we experienced with CKR is just something you don’t see much these days. They walked us through every step of the way. When there were unforeseen delays (there always are in any industry) they kept us informed and updated. The owner, Chris, was at our home during the install (almost the ENTIRE time) answering questions and getting to know us. It was somewhat sad when they were done because we had gotten to know the CKR team and really liked them. There are so many examples of what they did right, it’ll be easier to say what they did wrong. NOTHING! I mean it! There are few opportunities when you spend this kind of money but never have we made such a large purchase and walked away feeling like we were taken care of. That is, until we did business with CKR. Again, if you’re even just thinking about Solar, give CKR a call, you won’t be disappointed!

Solar Technology Alabama installed a grid tied PV system on our gymnasium to help offset some of the energy consumed by 30 tons of air conditioning. Ron Holland is a very conscientious and knowledgeable person who takes the time to answer any question you may have about what he is installing. His employees are very professional and they will leave your job site as clean or cleaner than when they arrived. I would definitely recommend Solar Technology Alabama to anyone interested in on-grid or off-grid alternative energy.

They install solar system with battery to my moms and I and said we won’t be paying for electricity anymore and our bill has been over $250 a month plus the system. On top of that the commission that their sales guy offer me still waiting on final payment. I wouldn’t recommend them at all!!!!!! They need to take ownership over this and choose well their sales team as they will say anything to sell you a system.

Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Solar panel manufacturer | Avg. cost per watt |

Canadian Solar | $2.13 |
LG Solar | $2.53 |
SunPower | $2.66 |
Panasonic | $2.56 |
LONGi Solar | $2.05 |
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 Huntsville 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 Huntsville.
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.
System information | Value |
---|---|
System Size (for 100% usage offset) | 12.83 kW |
Annual power generation | 18,122 kWh |
Pay-back time (assuming Cash purchase) | 9.2 Years |
Internal rate of return (IRR) on investment | 6.7% |
Gross cost | $34,176 |
Total Upfront Incentives and Rebates | -$12,385 |
Net Cost of System after rebated and incentives | $21,788 |
Total Cost of Utility Power Avoided over 25 years | $75,868 |
