Yes and no.
Done the way the solar has been with government subsidies, it is insane.
Pumping electricity into the grid at mostly off peak times, little if any when it's really needed.
Utilities still have to maintain expensive peaking stations for morning and evening peak usage.
Solar hot water heating can cut home energy usage considerably.
About 20 years ago I bought 2 used 4X8 Grumman collectors and installed them myself.
They paid off by the end of the summer.
2 years ago I relocated them and made the tilt adjustable for winter use.
Turned it into a propylene glycol loop with a flat plate heat exchanger to move the heat to the hot water storage tank.
Now we get 75% or more of our hot water from the sun in the winter, and 100% in the summer, plus on clear days some house heating from it.
Next will add some evacuated tube collectors that work on cloudy days and add more storage to heat the house partially with solar, the rest a System 2000.
If you buy your stuff new and pay someone else to install it, it will take a few years to pay off, depending on what you bought, who installed it, your present energy costs, etc.
Electric solar is getting close to cost effective if you do it yourself.
I am part way there and plan one being able to go off grid in about 5 years.
The big expense now is the batteries.
Nothing I have done or will do qualifies for government subsidies, which I think are a crock of crap anyway the way they have been done with wind and solar.
The way they do it now doesn't make electrical, environmental or economic sense.
It would make sense to subsidize if you really were making a difference energy wise to prevent us from importing oil from Muslim countries.
For the time being with technology what it is, solar water heating is the only way that works economically.
The problem there is you need a homeowner or business owner who is capable of maintaining that system, which these days, few are.
Solar electric with your own battery storage, especially if you have an electric car can make sense. I prefer it just because I like being independent as much as possible.
In the next few years you are going to see more and more wind turbines idle or burned up when the 5 year maintenance contracts run out.
Then the boondoggle will be even more obvious.
