You're on a CCA. Does That Change Your Solar Decision?

There is a line on your bill from a company you never chose, and now you are looking at solar quotes and wondering whether the two interact. They do, in exactly one place, and it is worth understanding before you compare quotes rather than after. A Community Choice Aggregator does not change what a solar system produces, what it costs to install, or whether your roof works. It changes who credits you for the power you export, which is one input into the numbers on a quote. The thing to watch is that an installer's estimate may assume your utility's export rate when you are actually on a CCA paying a different one. What a CCA is, briefly Most of California is now served by one. A Community Choice Aggregator buys the electricity, your utility still delivers it, and you were enrolled automatically rather than asked. That is why the line appeared without a decision on your part. Your utility still owns the poles and wires, still reads the meter, still shows up when the power goes out. Roughly half your bill is delivery and none of that moves. What it does not change about going solar Almost everything, which is the useful part. Your roof is your roof. Orientation, shading and available area decide production, and no billing arrangement touches any of it. The install is the same job. Same equipment, same permit, same inspection, same interconnection application to the utility. Your eligibility is the same. Being on a CCA does not disqualify you from net metering or change which version you get. That is set by when your system is approved, not by who sells you generation. The system size you need is the same, because it comes from how much electricity you use, which is a number on your bill and not a function of who supplies it. What it does change: who pays you for exports Here is the one real interaction. Once a system is running, anything it makes beyond what the house is using goes to the grid, and you get credited for it. Under a CCA, the CCA sets that credit rather than the utility. Several California CCAs have paid a small premium over the utility rate. Some pay the same. It is a published number. Your CCA lists it, and so does your utility, and the difference between them is usually small. But it is an input to every projection anyone shows you, which brings us to the part that actually matters when you are shopping. The comparison trap Quotes get built from assumptions, and the export rate is one of them. If an installer's software models your exports at your utility's rate and you are on a CCA paying something different, the projection is wrong. Not dramatically, usually. But you are trying to compare offers, and if one company modelled your actual CCA rate and another used the utility default, you are no longer comparing like for like even before you get to equipment and price. This is worth one question, asked of everyone who quotes you: what export rate did you use, and is it my CCA's rate or the utility's? A company that can answer that immediately is paying attention to your account. One that cannot is quoting from a template. That tells you something beyond the number. It is also the general shape of the problem with solar quotes. Two proposals showing different lifetime figures often differ because of the assumptions underneath rather than the hardware on top, and the assumptions are the part nobody volunteers. What you should actually do about it Not much, and that is the honest answer. Do not delay the decision over this. The export rate difference is small relative to system size, equipment choice and price, and those are the things worth spending your attention on. Do find your CCA's export rate before you compare quotes. It takes five minutes on their website and it lets you check whether the numbers you are shown were built for your account or for a generic one. Do ask the export-rate question of every company you talk to. The answers will vary more than you expect, and the variation is informative. Do check which plan tier you are on. Most CCAs run more than one, the default is not always the cheapest, and switching tiers is a separate and much simpler decision than anything to do with solar. The one thing worth remembering A CCA is a billing arrangement, not a technical one. It does not make solar work better or worse at your house. It changes one number in a projection, and the risk is not that number itself but that different installers use different versions of it without saying so. That is general information about how these programs work, not advice about your account. Your CCA and your utility both publish their current rates, and those published figures beat anything written here. If you want quotes built on the same assumptions rather than four different sets of them, compare offers from vetted installers side by side and ask each one the export-rate question.
