Sungrow Power Supply Co. (300274.SZ) stock: Winston Score, insiders and Congress trades

Sungrow Power Supply is a Chinese company that makes inverters and energy storage systems for solar and wind power. Inverters convert the electricity generated by solar panels into the type of power that homes and businesses can use. Sungrow is one of the world's largest inverter manufacturers by shipments, serving utility-scale solar farms, commercial buildings, and residential customers. The company earns revenue by selling inverter hardware, battery storage systems, and related power conversion equipment. It is headquartered in Hefei, China, and sells products in over 150 countries, making it a major global player in the clean energy supply chain. Its scale, broad product lineup, and strong R&D spending give it a cost and technology advantage over smaller competitors. Key growth drivers include rising global solar installations and increasing demand for energy storage, though the business faces risks from trade restrictions, pricing pressure, and dependence on government renewable energy policies.
