I Bought a House with Solar Panels

No, pretty much all sales and advertising is built around finding some problem the customer has that the product or service being sold solves (or solves better than their current solution). But there's no need for the problem to be pain and fear--let alone pain and fear that is a perception created by a sales pitch that has no qualms about playing fast and loose with the truth.

I pay US$7.94 a month to my utility to "store" megawatt-hours of electricity over the course of a year. Brand-name home battery storage is still well over $500 per kilowatt-hour installed.

So yeah, I'll engage in shameless commerce with the evil corporate utility if they'll loan me a $2.5-million-dollar "battery" for less than 8 bucks a month.

We didn't get exactly the rig we wanted. As a typical HN reader, I learned more about solar than their customer-facing staff, and had to periodically be put on the phone with a techie they usually insulate from customers. One problem was working around a revered shade tree we had no intention of hacking to optimize solar yield in late afternoon. One shaded array in a string is like one bad battery in a flashlight; that string's output crashes. I determined that we wanted two strings on independent converters, so half the panels would be unaffected. I was willing to pay whatever this cost, but they wanted a simple pricing model. They agreed to my request. Studying the wiring after installation, it was clear that the strings couldn't possibly be independent. It took calls to Germany to understand that the converter algorithm was tuned to "fake" two independent strings, like someone learning to walk with a lame leg. As spelled out in the manufacturer manuals, the algorithms claimed to optimize for the better string, even though they only saw the combined output. They lied about what they were actually installing, or more likely, the customer-facing staff were too ignorant to understand the swap being made without my consent.

There was a full-court crush to get our contract signed by the end of the year, ostensibly to have a chance on a limited number of expiring state-sponsored favorable time-of-day rate plans with PG&E. The state office was swamped with a backlog of unprocessed requests, though it strained credulity that SolarCity wouldn't have some idea about our chances. Of course they knew we had no chance; I found out through a back channel that they never filed until January 7th, making us ineligible. This deception speaks for itself.

Our panels cover various roof vents. This is not allowed by code in many locales. One day, a plumber snaking our bathroom sink drain gave up on the new snake his boss was making him use, and said he'd just go up to the roof and snake from there. (This is standard drain geometry in a house.) He came back down mortified: Our panels were blocking his access. He managed with a different snake, then we discovered the cause for his mortification: Our solar was out as of his visit. His original snake had gone up, not down, and shorted a panel. The panel was fine, but some component near the regulator on the side of the house had literally exploded.

SolarCity repaired this promptly, without charge.

There are schemes where you can get fixed price SRECs by signing them over to a 3rd-party. The third-party then give you a fixed amount monthly or quarterly or whatever but it's a significant discount on the auction price.

There are also companies that will give you a lump sum for your 10-years of SRECs up front but like all 'need cash now' schemes there is a significant discount.
