  • Is the solar power industry good

    Is the solar power industry good

    Policymakers in some of the world's largest economies are reducing support for solar power generation. Even so, Goldman Sachs Research expects rapid growth in the sector, with global solar installations set to rise to 914 Gigawatts (Gw) in 2030, 57% above 2024 levels. Solar energy converts sunlight into electricity through photovoltaic cells or solar thermal systems. The key drawback is intermittency — no generation at night — and upfront. Despite tax incentive cuts for solar, these companies' technical expertise, customer relationships, and established roles in the clean energy ecosystem will allow them to easily pivot their business. 7 gigawatts direct current (GWdc) of capacity in Q3 2025, a 20% increase from Q3 2024, a 49% increase from Q2 2025, and the third largest quarter for deployment in the industry's history. 69 billion in 2023 and is projected to be worth USD 273 billion in 2024 and reach USD 436.
