TL;DR
A solar production guarantee is a contract clause in which the installer or financing company promises the system will generate a stated number of kilowatt-hours annually, typically 90 to 95 percent of the modeled estimate, and pays the customer for any verified shortfall. It is standard in leases and power purchase agreements and increasingly offered on cash sales as a performance backstop.

It is standard in leases and power purchase agreements and increasingly offered on cash sales as a performance backstop. The fine print matters: weather adjustments, monitoring requirements, and shading exclusions determine whether a shortfall actually pays out.
