*Prices are shown after applying the 30% federal tax credit.
As of May 2024, the average cost of solar panels in Grand Cane is $2.33 per watt making a typical 6000 watt (6 kW) solar system $9,790 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.

High pressure sales will tell you they should be able to do anything you want to get you to sign the contract that has no protections for the customer if they do not deliver what you want. Then once you get passed the 3 days you have to cancel, they will give you song and dance till eventually they tell you they can't do what you asked for, but hey your locked into the contract and if you don't take what we want to give you, you'll have to pay 10% of the contract price and get nothing. Which is the route I took as it ended up being cheaper to pay them the 10% and hire a different solar vender. It was all cheaper in the end. Also, they Charge almost a 22% service fee up front on loans in addition to the 8-9% interest rate you'll have to pay over the life of your loan. Basically, they are using the government tax credit to subsidize their lending group.

I recommend South Coast Solar for anyone wanting a solar solution for their home. They installed a 14KW whole home with 4 Tesla batteries for back up. Sales person - Rebekah Olinde 100% professional, realistic and knowledgeable. She IS THE reason I chose South Coast over other companies. Technicians - Professional, knowledgeable, trustworthy, clean and efficient. No complaints, work was done timely and on schedule. Happy.

Our installation was done about five years ago. When it was done we paid the full price and it took Gulf South Solar about 6 more months to finish installing the ducts to our heating system that had been moved as part of the istallation. The result was that we had carbon monoxide going into our attic the every time we used the heat and we did not know it. Our heating company told us about it. <br /><br />We have been without our solar power since Thanksgiving, almost four months now. First, one board in one of the inverters quit and then the second board quit. The repair person is very nice and competent. But it takes forever to get things repaired and they typically do not return my emails.

Eddie Haynes and crew KNOW solar energy. I had all sorts of issues regarding the age of my solar power system. Eddie took the time to research all available options and costs associated with getting me back up to speed. My wife and I are far more pleased with JEH than we’ve ever been with the outfit that did our initial installation. If you’re considering going solar, save yourself a lot of headaches and unnecessary costs. Give Eddie a call!

Solar Energy Services provides great service with a friendly and professional staff. I dealt with the same people every time I contacted the company, with no run-around or loopholes. I am very satisfied with my pool heater and look forward to dealing with Mr. Hebert and Solar Energy Services in the future.<br />

We purchased our solar system in 2015 right before the state tax credits where due to expire. When we submitted the paperwork to the state we where rejected because the paperwork provided by the installer was incomplete. When we contacted the installer they said they no longer did solar and come to find out a lot of companies did the same after the tax credit expiration. Luckily for us a friend recommended Raji Mugrabi with Bayou Solar and he walked us through getting our tax credit money back and since then on several occasions has helped with minor maintenance since then. Its sad that the tax credit expiration shut down nearly 200 installers in Louisiana but thank god a few of them stayed around to help people out like Bayou Solar has.

I live in Arizona and purchased a solar system for my home from Green Home Systems. It worked ok but didn’t produce like I was promised. It stopped working in September of 2023 and to this date (April 2024) they have NOT fixed it!! They finally sent a tech in December of 2023 who diagnosed the problem to be a bad Solaredge converter. GHS told me “its just a fuse inside the inverter.” What a joke these people are! Nobody has been sent to change this “fuse” and after several phone calls to GHS they said to me, “Do you know anyone who can change the “fuse?” How unprofessional is that!! It is GHS warranty and they told me if I worked on it it would void their warranty! But they do absolutely NOTHING to repair my system! So as of now I am out of pocket paying for a system that doesn’t work AND a monthly electric bill. So warning to all DONT USE GREEN HOME SYSTEMS!!!

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 Grand Cane 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 Grand Cane.
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) | 10.97 kW |
Annual power generation | 14,882 kWh |
Pay-back time (assuming Cash purchase) | 10.7 Years |
Internal rate of return (IRR) on investment | 3.6% |
Gross cost | $26,047 |
Total Upfront Incentives and Rebates | -$6,772 |
Net Cost of System after rebated and incentives | $19,274 |
Total Cost of Utility Power Avoided over 25 years | $54,636 |
Please note that the investment return figures do not include the possible increase in property value
