How it works

Two steps to the price lock value

Step 1

Get the escalator rate from the offer you're comparing against

This should be stated clearly in that provider's contract. Check the escalator rate calculator first if you want to see that contract's savings trajectory in full detail.

Step 2

Use the same subscription size, rate, and discount for both

This isolates the escalator's effect specifically, rather than mixing in differences from other contract terms. For a full side-by-side including all terms at once, use the provider comparison tool instead.

Understanding what a price lock is worth

Why the value compounds over a longer contract

An escalator applies year after year, so its cumulative effect grows substantially the longer your contract runs. A 20-year contract avoiding a 3% escalator can be worth thousands of dollars more than the same terms with the escalator included, while the same escalator over a 5-year contract represents a much smaller dollar difference. Contract length is the single biggest driver of how much a price lock is actually worth, similar to how the subscription cost per kWh tool can reveal the true effective rate across a term. A fixed-rate rooftop loan offers the same kind of predictability, covered by the fixed versus variable rate loan comparison.

Why a price lock isn't automatically the better choice

A provider offering an escalator might offset it with a stronger starting discount or credit rate, meaning the price-locked offer isn't necessarily the better deal overall once you account for every term. Always compare total cost over the full contract term rather than treating the presence of an escalator as an automatic dealbreaker. The savings versus rate inflation projection tool is a useful companion for weighing this same tradeoff against a rooftop system.

How a price lock interacts with rising utility rates

A price lock only fixes your own subscription cost, it has no effect on the utility's credit rate, which can rise independently based on typical utility rate growth. When your subscription cost stays flat while the credit rate you're being measured against continues rising, your savings actually grow larger each year, which is the most favorable outcome a subscriber can have. The Department of Energy's community solar basics guide covers the underlying bill-credit mechanism this favorable outcome depends on.

Using this alongside a full provider comparison

Once you know what the price lock itself is worth, weigh it against other differences between offers, such as contract length flexibility or cancellation fees, using the contract length comparison tool and developer fee comparison tool for a complete picture before deciding. Check the DSIRE database too if you're comparing offers across more than one state.

Questions

Frequently asked

A price lock means your subscription discount or price stays fixed for the entire contract term, with no annual escalator increasing what you pay. This protects you from paying progressively more each year the way a contract with a 2% or 3% escalator would.

This depends heavily on the escalator rate being avoided and the contract length, since the value compounds over time. A 20-year contract avoiding a 3% escalator can be worth thousands of dollars more than the same contract with the escalator included, while a 5-year contract avoiding the same escalator is worth considerably less.

Not necessarily, since a provider offering an escalator might offset it with a better starting discount or credit rate. Compare the total cost over your full contract term, not just the presence or absence of an escalator, to make an informed choice.

No, a price lock only fixes your subscription cost, not the utility's credit rate, which is a separate figure that can rise on its own. A price lock combined with rising utility rates typically means your savings grow over time, which is the ideal scenario for a subscriber.
