Nope only when the sun is out. Have hot water heater on a timer it runs from like 7pm-10am

Yes, takes some work but worth it.
Yes it is saving on heating costs.

I was thinking of making a solar water heater for my hot tub...I bet that would keep it pretty hot...

can you message me where you got the setup from so i can look into it?

Actually they were my dads that he is letting me use. The one I should have done tomorrow needed some work done to it to work again.
There are many videos on YT about how to make them for you to check out.

It’s scalding hot for me in Hawaii. Can’t run it full hot or I will burn myself.

For solar hot water it’s not much of a setup, you just put the panels on your roof similar to PV and then hook it up inline with your hot water system. Prolly gonna want to hire someone unless you feel confident in your plumbing and sealing penetrations on the roof

Got the second panel up and it got up to 136 degrees yesterday!

our neighbor has a tesla roof. it produces so much energy they can power their entire house with it, including heating. they even have enough surplus energy to sell some of it to the power company.

Nice! I'd like to do something like that someday...
