The brokerage firm said it anticipates " lower costs for solar and favorable policy support ... to drive meaningful upside to the market," and forecast year-over-year utility-sector solar installation growth of 12% in 2019, and another 10% in 2020. Further, Goldman said it expects "some of the strongest growth to materialize in key regions such as the U.S., Europe, and the Middle East."
