US PV panel maker First Solar will supply independent power producer Silicon Ranch with 4GW of latest generation thin film cadmium telluride (CdTe) solar modules from 2023-2025 for use in its US solar projects.

Financial terms were not made public for the master agreement, one of First Solar’s largest. Nashville-based Silicon Ranch began contracting PV modules from First Solar in 2015 and has installed more than 1GW in 30 utility-scale projects in US southern states.

“Long-term module supply agreements with a trusted partner provide a vital hedge against the pricing and supply uncertainties that have impacted the solar industry over the past few years,” said Georges Antoun, chief commercial officer, First Solar.
