Put a real dollar figure on what sitting on a waitlist costs you in missed savings, so you can weigh it against enrolling somewhere sooner.
How it works
Step 1
Ask directly rather than guessing, since waitlist estimates vary widely between programs and regions. If you're comparing multiple providers, run this for each one's estimated wait using the provider comparison tool alongside it.
Step 2
If the missed savings during a long wait outweigh the benefit of holding out for a better offer, enrolling sooner with a decent option may net you more overall. The enrollment timing calculator covers this tradeoff in more depth.
Every month spent on a waitlist is a month of full-price electricity that a subscription discount would otherwise have reduced. A $150 monthly bill with a 10% discount and a 6 month wait costs roughly $91 in missed savings, a number that's easy to overlook when a waitlist feels like a minor scheduling detail rather than a financial one. A rooftop installation can face a comparable delay from permitting and interconnection timelines, covered by the grid interconnection cost estimator.
As your utility rate rises over time, the dollar value of a fixed discount percentage rises with it, so a missed month later in a long wait costs more than a missed month early on. This is why an 18 month wait costs more than three times what a 6 month wait costs, not just three times as much. Run the subscription savings calculator for the full picture once you're enrolled. The Department of Energy's community solar market trends data confirms that subscriber demand and program capacity have both grown quickly, which helps explain why waitlists have become common.
A longer wait can still be worth it if it gets you into a meaningfully better program, for example a significantly higher discount or a more favorable credit rate structure. Compare the missed savings from this tool against the actual difference in discount using the subscription cost per kWh tool for each option before deciding. The gap between an offer's advertised and actual savings is exactly what the real versus estimated savings gap calculator is built to catch, worth running before committing to a longer wait for a "better" program.
Some providers allow joining multiple waitlists simultaneously, which can shorten your effective wait since you enroll wherever capacity opens first. Check the eligibility checker tool to see what other programs might be available in your utility territory in the meantime. Check the DSIRE database too, since a strong state incentive program might make a shorter wait at a nearby array worth prioritizing over a longer wait for a marginally better one.
Questions
A $150 monthly bill with a 10% discount and a 6 month wait costs roughly $91 in missed savings, growing to about $276 over an 18 month wait as utility rates rise during the delay. The exact cost scales with your bill size, discount rate, and how long you wait.
Compare the missed savings from waiting against the difference in discount between the two options. If the wait is long and the discount difference is small, enrolling sooner in a slightly less favorable program often nets more savings overall.
A shared array has a fixed subscriber capacity based on its size, and once that capacity fills, new subscribers wait for a new project to come online or for an existing subscriber to leave. Popular programs in high-demand areas can have waitlists stretching many months.
Yes, joining more than one provider's waitlist is generally allowed and can shorten your effective wait time, since you can enroll with whichever program opens capacity first. Just be sure to withdraw from the other waitlists once you enroll somewhere to be considerate of other subscribers.
