Solar company Sunrun, which installs solar panels on the rooftops of homes, has set the terms for its planned IPO, which could raise up to $309 million. The eight-year-old, Silicon Valley-backed company, first filed its IPO plans last month.

The company, which will list under the symbol “RUN” on the Nasdaq, plans to sell 17.9 million shares at a price range of $13 to $15 per share. Underwriters have an option to purchase an additional 2.69 million shares. At the mid point of that range, and excluding the additional shares, Sunrun could raise closer to $251 million in the offering.
