Unless the panels are subsidized by tax dollars they’re not worth the purchase and installation cost.

It won't last as long as they say it will.

They won't warrant it so you pay more when it breaks and won't help offset costs if production falls off.

You still don't have power when grid goes down.

They won't get it installed in time, so you are financing, perhaps, 8 months into something you're not getting ROI on.

If you sell your house this becomes a pain point more often then not. (Lein on your house.)

You need to cut the trees down around your house for it to become most efficient.

You need to get on roof to clean them.

I suspect DIY is best way to so it (saves you 20k plus finance) or using company called SunRun seems to be a good option. Sunrun you don't own the equipment and they lock your utility bill price. But they only operate in like 5 states.

If you live in the tropics, go for it. If you don’t, it’s not likely you’ll ever recoup your investment.

7years now going strong.
2,400sq k house runs 93% peak on panels
There are tricks and tweeks you learn over time.
6 ton AC is set on 65° when its 120+°
Soaks up alot of free juice.
Massive savings after 2-3 weeks of killer heat.

First and foremost, it would depend upon your environment, and where your house is situated. If you are southerly facing, in an environment that gets a lot of sun, it could potentially pay dividends.

However, even if you live in a environment that gets a lot of sun, you need to think about what kinds of storms that you get as well, as dust / debris, etc.. will make them lose their efficiency.

Lastly, if you do go forward with them, be wary of many of the contractors out there, as there are plenty of scams where you are paying the fuckers off in a 20 yr. installments, when they might only last 10-15 based upon the conditions that they are put through. Also, the quality of the product as their is a lot of variance there as well.

I looked into it, but it did not make sense for my situation.

Direct Solar Power (no batteries)

All the people saying solar panels are shit?
ProTip: They don't have solar panels.
These NPCs don't actually know what they are talking about.
All they are doing is mindlessly parroting something someone somewhere told them at sometime.

Here's what you need to know.

Step 1: Can you put a solar panel out in the sun and plug something in to it and get electricity?

Step 2: Now run some math and ask yourself if owning your own electric company that YOU control is worth the cost of reducing your reliance on someone else to provide electricity for you.

Solar power is an expensive backup for your house.

The panels are expensive, highly toxic, last a maximum 5-7 years regardless of what they promise you, and their capacity to generate power dwindles over time.

A battery storage system is also needed if you want power at night or in heavy cloud cover, and those are expensive, highly toxic, never last as long as promised, and dwindle storage capacity over time, also.

Remember, a warranty is as good as the company that provides you the warranty, so if you get solar, read the warranty (usually because it's pro-rated) and look into the likelihood that when you need a warranty replacement, that the company that warranties your panels might be long gone.

I did lots of research on solar about 5 years ago as consideration for my tiny home. (@550 square feet) I was unimpressed. A deisle generator and a tank of fuel is far more reliable.

I watch that last few years, but it really depends where you live, and most info you will get on websites of those who actually make them, specially their instructions about maintenance.
First thing I noticed, there is great business for those who now clean installed panels, that tells you a lot, so it's good to check info about these maintenance companies.

I think I would already get them, if living in some California-like place, but for climates such is central Europe is different. For those who install solar panels in more "rural" area, I seen there are instructions one should not even put them close to barn or any source of pollen.
So even if living in city, or maybe US suburbs, depends how "alive" is the area - we have zillion of birds and with that comes all normal natural insects, bees, etc, also lots of plants and trees everywhere- so if you live in nice environment, you would have to clean those panels a lot, if not every year, which would be costly if you can't do it by yourself.

Also, one should think about fire safety - if for some reason something get on fire, then I think firefighters are not able use water, but chemicals. Lots of wires in the attic means also things can happen with some cheap installation, or if it's not regularly checked.

I know only those who installed it with some huge state green subvention, so with others people money, are happy, mostly use it in summer for air conditioning... otherwise will not pay off here allegedly even after 10 or more years I was told by some. During winter get covered with snow, and not sure if one have stronger wind, or hail, what would happen. So a lot of things for consider, but for very specific areas solar may be good.

It depends on your use case. My boat is 100% electric, solar only, and even on cloudy days it's more than enough, and we have AC.

Many people don't know this but sloppy bird shit, seagulls & crows especially, will eat through the panels.

You need majority of days to be unclouded sunlight...250 or more is ideal (eight months of sunny days). An easy ask for southern California and the desert southwest US, but anywhere else its just an expense.
