When GT solar rolled out in our neck of the woods - about 6-8 years ago, the energy leases were all the rage. I quickly saw thru that, no thanks.
At that time most of the commercial installing companies were charging $4 to $6 a panel watt for systems. Doing some reasonable research at the time showed I could install myself for under $2. Prices are even less today. So the only way it made sense to me was to buy the hardware and install it. Hire an electrician to connect to the grid.
I had a couple of major challenges however - one was my 100A electrical panel - it's about $1200 for a new one. At least one solar company was going to pony up the cost for the re-panel for the deal. That should tell you what kind of profit-model they were working with. I have room for maybe a 5-6kw system, so for a 'tier-clipper' that was potentially do-able.
The second challenge was the intention to move after retiring, just a few years off. And calculating payback on the investment, it was way past when we would already be gone. So it just didn't make good financial sense, even with rising energy costs.
And we're energy hogs - pool and pond pumps, AC, computers and big-screens all around, lots of lighting - the power company sends those silly usage comparison reports and says we use twice as much as our neighbors. But I PAY for it so STFU, right?? LOL
My next place, whether I buy or build, will have a solar generation backup, so that grid utility would be a minor expense. And we won't have a pool again. And I don't need a grid-tie system to benefit. Plus I can be self sufficient in case of grid down.
The next challenge is internet data off grid, and so we're waiting for this Starlink thing to be available. Could well be the answer to our remote dwelling opportunity. Oh, and our own well and septic system, and enough land to be able to fence out the neighbors and have a big dog. We are so sick of our zero lot line we could scream.
I don't generally recommend GT PV - do your own math, see if it makes sense for you. One of our neighbors just installed a Tesla roof - the power-tiles thing. It's cool, but some quick research generally says choosing this option means you have more money than brains. LOL
I'm using this forum to learn system building for when that day comes.
