Solar panels for the house

OK I searched and didn't find anything.
Anyone have solar panels? Cost? ROE? Anything else I need to know is appreciated.
BTW I hate the look of them.
TIA

I'm planning on using the 11kw (Panels) 13kw (inverters) and 20kw (batteries) kit from signature solar. Those are 445 watt or so panels that I intend to mount to a porch awning and not on the main roof.
Kit from signature solar
I believe you get the 30% tax credit with any solar setup.
I'm figuring around a 90$/month cost spread out over 10 years. Some components will last longer, some shorter, the li fe batteries are stout and 10 years should be doable. The kit listed is expandable to 16kw panels on the inverter/charge controllers.

At $15K+ will you ever see a true savings? Will you be able to sell any overage back to the electric companies?

I actually heard a guy that works for Entergy Arkansas discuss this at our schoolboard meeting the other night. He said they have guys that have crunched the numbers on them for consumers and businesses and right now it's still not cost effective to install them due to the up front costs. I do realize that you take that with a grain of salt realizing they still provide a service and the solar will have an effect on their business. But they are moving to solar fields in some areas to help supplement the power grid. Our school is actually part of a cooperative on one (Stuttgart field I believe).
He just said the residential ones aren't yet showing the benefits of savings vs up front costs.
Take that for what it's worth.

Thanks and this is what I thought too. I have solar panel companies come by all the time and the first thing I say when I open the door is "if you're selling solar, I ain't buying"....it greatly shortens the conversation

Even worse in Louisiana since the public service commission changed the net metering policy in 2019. Excess electricity you sell back to Entergy is at an avoided cost which is a small fraction of the retail rate. Anyone who had solar before the change was grandfathered in for 15 years to the old policy which was selling back at the retail rate. Only reason to install solar now in LA is if you have no other option to get electricity. It will never come close to paying for itself.

Post this on home and garden board as well.
That being said, the companies that are selling solar to individuals are some of the worst companies. They are absolutely ripping your face off at their levels.
not only that the finance levels are horrible.
Then you need to know what levels you can sell back to the energy companies are at your location. Many energy companies are cutting that out or reducing it to levels that make it not worth the expense to install.

I used to be a director at a national solar company, and I was principle level at GE Power, so let me answer for you.
Will you ever see a true savings?
I suppose this depends on your definition of "savings," so I'll use ROI for this. Timelines will depend on how much sun you get, how shaded your panels are, etc. but yes you will definitely get a return on your investment (defined by the delta of solar production against grid consumption as offsets vs your initial installation costs). Chances are the breakeven point will occur 7-10 years after initial install if you have no shade and live in Louisiana.
If you combine tax incentives with this, it will likely be sooner.
Will you be able to sell any overage back to the electric companies?
Depends on if you live in an area with net metering. If you do, your ROI timeline will contract because you'll be compensated when you generate more than you consume.
Other comments
If you go with solar, a DIY-ish set up is your best bet. Unfortunately most solar companies are run by morons who just know how to schmooze investors. Solar wholesale is a great option for this.
Calculating your ROI really depends on a lot of variables. While you definitely will hit break even, when you do depends on a lot of things beyond shade and roof angle. When you use your power matters. For example, to save on energy today it's best to run your appliances at night when it's off-peak. If you're trying to use solar, is night the best time? Of course not.
So anyone saying it's a one-size fits all answer is lying to you. It depends on where you live, how much you can install, how you manage your energy usage, whether or not you get battery storage (which will hurt your ROI), etc.

That's a good resource for calculating tax credits and incentives.
https://www.energysage.com/solar/calculator/
A decent calculator for ROI (which has my house at 14 years base ROI).
Edited to add - The division I ran, and my entire project that I owned, was a project that took customer goals and showed them outcomes based on those goals. If your only goal is ROI, rest assured you will more than break even over the lifetime of your panels. But, if your goal is net-zero, that's a different issue. Likewise, if your goal is like mine - energy availability after a hurricane, that's also a different issue. Each of these goals has an effect on the other areas, so it all depends on what your goals are and from there you can craft the best solution for you.

I'm going completely off grid with a manual transfer switch for emergency use/repair and will not be selling anything back.
My current meter is listed as agriculture and I'm going to have an 80 amp panel in the barn side (true barndominium) that stays hot.
I'd have new service costs to deal with the local utility if I were to add the Barn to the grid.
There's another item I intend to take care of with the system, When we trenched to the barn, we ran a separate 6/2 back to the existing meter by our well house. I intend to keep our two ponds filled (I irrigate with a tractor pto pump) with the panels and not run the pump on the grid if my batteries are topped off. I have run a 140$ bill in the summer strictly from pump use and the solar setup can allow me to run the well a lot more than what I did in that instance.

Can you post energy use info for maybe average and peak months? Florida right? How far from the coast (hurricane concerns).

This is awesome. Not at the same scale, but this is exactly what I did for my chicken coop for a fan in the summer and a heater in the winter.
I live in a neighborhood though so I don't have the space you do. One thing I'd throw out is consider wind too. There are some good consumer grade wind turbines coming out that obviously run day and night.

Over the past year the average is 1,269 kWh per month with summer being the peak; 1482 in Jun, 1749 in July and 1602 for Aug.
Florida yes
I'm about 20 miles or so from Tampa so maybe 30ish from the Gulf Coast.
