Bidders must also obtain net-metering and grid connectivity for the rooftop systems. They must also take all necessary permits, approvals, licenses, and insurance for the projects.

The projects must ensure an annual capacity utilization factor (CUF) of at least 15%. Selected bidders must pay penalties for shortfalls in energy of up to 50% of the PPA tariff.

The project must be completed within seven months from the effective date of the PPA. The maximum time allowed to commission the projects, with the applicable penalty, is limited to six months from the scheduled commissioning date.

The projects must only use modules and cells listed on the Approved List of Models and Manufacturers. The modules must be warranted to deliver at least 90% of peak output at the end of 10 years and 80% at the end of 25 years. They must also be warranted for at least 10 years for failures due to material defects and workmanship.
