Israeli-based company SolarEdge Technologies (SEDG - Get Report) said over the weekend that its founder, Guy Sella, has died. Sella was also a co-chairman of the company.

"It is with a very heavy and sad heart that we notify of the passing of our dear friend and inspiration, Guy Sella. All of us who had the privilege to work with Guy and be witness to his unwavering drive and infinite levels of energy and passion for what he did know what a huge loss this is, not only to SolarEdge. Guy has left an incredible legacy and his spirit will live on forever in SolarEdge. The entire SolarEdge family mourns his loss. On behalf of our Board of Directors, management team and employees, we extend our deepest sympathies to Guy's family."

The solar-energy technology company said last week that Sella had taken a sudden leave of absence because of a health condition. He had earlier been diagnosed with colon cancer, but the company did not disclose the cause of his death.

SolarEdge's vice president of global sales Zvi Lando has been appointed acting CEO.
