Deprecation on a Schedule C

I think it smells.

Some solar companies sold this idea.

Schedule C is a business.  A business is an ongoing activity that tries to make a profit.  What did he do THIS YEAR to try to make a profit?

I think you have two scams here.

The discount wasn't income and is not a business activity.

The generation isn't a business activity, either.

The latter idea was sold by solar installer companies with the stamp of approval of "our CPA." They even posted the approval letter. The strategy is, if your solar installation has a production value for meter reversal as credits or Net Metering, they tell the residential owner to treat it as production.

Sometimes there is a kernel of truth in what is otherwise a scam. In many places, utilities are required to buy back the homeowner’s excess power generation from solar installations. This is first applied to the owner’s bill for delivered electricity, but it’s possible for actual cash payment to be made if the credit is more than the bill. Does IRS tax this? Why not? It’s like renting a room in your house, but it’s space on your rooftop instead.

I found a PowerPoint presentation on this that concludes, “Note: if the customer is a net exporter of electricity and receives a check, the customer has income.” It’s by a Harvard Law graduate:

Let’s say a vendor sells a $20,000 system to a homeowner for $30,000, because these buyers don’t care how much they have overpaid as long as they get a tax credit to offset some of the gouging. Then it turns out that 95% of the power generated is used at home, but 5% is sold back to the power company. Shouldn’t 5% of the unit’s cost (net of tax credits) be allowed as a deduction, if the payment is taxable?
