That's not how it works for my coworker who has their system. They installed it for free, and he just pays them for his electricity. If he overproduces during the day and doesn't use that much at night, he gets money back from his utility company. If his roof needs work, they come and move panels out of the way for free. And, when he goes to sell his house, the new home owner can be under the same plan or they can buy the whole system outright and roll it into their mortgage, freeing them from Solarcity entirely.
He loves it. I'd have it too if I wasn't surrounded by trees.
That is exactly how it works if you are leasing the system. Nothing is "free". This is the problem and it is why they are being pressured by Congress. They don't clearly state how much they are making. Sure, they'll move it for free, because they are moving *THEIR* property, that also is imbedded into the "cost" of the system, do you think they want some bonehead roofer moving *THEIR* property? What if the homeowner doesn't want to be under that plan? What if the lease is now included in the DTI/PTI/LTV of the home (which it is from what I understand) since it is not a contingent but a fixed liability with a known payment? What if they can't roll it into the mortgage since it's not considered a 100% improvement (it isn't, in fact, it hurts home values from what I have read). That means for a 20k system you now need to put in more equity, a lot more. You also can't afford as big of a house, since you now have another liability. What if the new person doesn't want it aesthetically?
You don't even realize the benefits they are getting, nor the equity returns they are reaping. It's hiding right under your nose and you don't get it.
I have been offered tax-equity toggle certificates that return 15%. That's *AFTER* the tax-equity is done reaping their profit. It's the scraps.
Think about it. They are selling scraps at 15% return. Scraps. How much are they returning before it becomes the "scraps"?
Think about this.
1. How much does the equivalent panel system cost out of pocket or by a loan
2. How much do you get for federal (or other) incentives?
3. How much is it worth not to have a UCC-1 filed on your house?
4. How much is the resale of the panel worth on the back-end (you own it, you sell it, you get cash out)?
5. Can you finance it with a HEL/HELOC which allows *you* to deduct the interest?
6. How much can you really sell the depreciation for? If they can depreciate 40-50% of the panel up-front (if not more) and reap 20-30% equity return from that depreciation, *PLUS* the government subsidies, they should be able to "buy" that from you for an equivalent deduction to the purchase price, plus a nominal secured financing fee.
You see, they are selling *YOUR* panel's depreciation to somebody who needs to offset revenue with depreciation and then they are stripping *YOUR* incentive away from you *AND* they are charging you an imbedded interest rate in the lease fee while generating power for free with a sub-par system on a 20-year loan and then they are financing that at a very low rate.
A 5-year Solarcity bond yields 4% with 5-year swap rates at 1.57%. That means you are earning 2.43% over swaps, which ain't much for an unrated, illiquid, relatively risky bond backed by an investment structure that heavily benefits other people.
