FTC Solar, Inc. (NASDAQ:FTCI) is one of the best renewable energy penny stocks to buy.

On March 10, 2026, FTC Solar said it signed a five-year, 1,000-megawatt expansion to its tracker supply agreement with Strata Clean Energy, deepening an existing relationship between the two companies. The new agreement is scheduled to take effect in the second half of 2027.

The deal builds on the companies’ earlier three-year, 500 MW tracker supply agreement that began in September 2024, under which FTC Solar became Strata’s preferred supplier. FTC Solar said the expansion followed the successful completion of the initial 500 MW of projects using its Voyager 2P solar tracker technology.

The company also said gross margin improved by about 1,500 basis points year over year, while management pointed to stronger commercial traction, a larger project pipeline, and continued recovery in its business.
