"We have had a strong track record of success with JinkoSolar's high quality and reliable modules," said Ryan Creamer, CEO of sPower.
"We are confident of JinkoSolar's technology roadmap and cost leadership and we look forward to maintaining our strong partnership."
JinkoSolar has supplied over 800MW- about 2.5 million solar panels - for sPower's PV projects. The agreement includes significant down payments, which will help Jinko expand manufacturing capacity in the US and Asia.
Gener Miao, JinkoSolar vice-president of sales and marketing, said the company looks forward to working with sPower.
JinkoSolar has been investing heavily in advanced solar technologies, and these efforts have yielded major benefits, he said.
