(quoted from post at 08:18:21 01/07/18) So you had to pay income tax on that state grant and finance that along with the 1/3 installation cost. What will be your net gain in energy savings after you pay off that loan ? Then also subtract maintenance costs, service calls, and degrading performance on the equipment. Like I said ... solar = salesman's dream.
Solar has come a long way in just the past five years, both in cost and efficiency. Guys who put in systems 10 years ago have less efficient, more expensive systems than guys who put one in last year. I imagine guys who put in systems five years from now will have better systems than the guys who put them in now. I don't know how it's been performing yet, but Tesla installed a battery pack in Australia a couple months back. That'll be the next thing.
Thing is, if you don't start now, when will you? I'm seriously considering installing a system in the next year, but mine will be on posts in the yard below the barn. That way, they'll be able to be adjusted for sun angle through the year. they'll also double as shade for the chickens when they're out to pasture.
Some of you guys are so negative about "new" things. I imagine if you were around 100 years ago, you'd be sitting on your horse, blowharding about how that new-fangled horseless carriage will never make it, what with its unreliability and its high cost of ownership, and how the roads it rides on are subsidized by taxpayers.
