Many solar leases promise a minimum amount of electricity each year. If your system
falls short, the lease usually says you're owed a credit. Since Sunnova, SunPower and
PosiGen went bankrupt, some homeowners are finding those credits aren't being paid
unless they ask.
GuaranteeCheck compares your system's real output with what your lease guarantees. If
there's a shortfall, it writes a claim letter for you to review, sign and send yourself.
Checking is free, and takes about five minutes with your lease in hand.
You only pay if a shortfall is found and you choose to get the letter.
We never contact your servicer for you. The letter is yours to send.

Either way, the check itself is free. You can change your mind later.
Step 1 of 3
Your lease and system details
Most of these numbers are in your original agreement. Nothing is sent to your servicer.
Step 2 of 3
Your result
Please double-check a few numbers
A couple of the values you entered look unusual for a residential solar lease. This
won't block you, but a wrong number in a claim letter can weaken it. Please check them
against your lease.

Step 3 of 3
Your claim letter
Since a shortfall was found, you can get a claim letter and evidence packet to send under
your own name. This step is $99, charged only because a shortfall exists.
