As of 2025, the federal ITC provides a 30% tax credit for qualified commercial solar installations. This rate is scheduled to remain at 30% through 2032, after which it will step down to 26% in 2033 and 22% in 2034.
[pdf] Key projects include the 300MW/1.8GWh storage project in Lijiang, Yunnan; the 200MW/1000MWh vanadium flow battery storage station in Jimusar, Xinjiang by China Three Gorges Corporation; and the 250MW/1GWh vanadium flow battery energy storage project in Chabuchaer County, Xinjiang by China Energy Conservation and Environmental Protection Group.
[pdf] In July 2025, Congress passed budget reconciliation legislation that significantly altered clean energy tax credits for solar and wind projects. This article explores the impact of the bill for commercial & industrial solar and storage projects.
[pdf] ISO 668:2020 gives the main rules for containers in refugee solar projects. These rules make sure each ISO container follows global shipping container standard guidelines. The standard tells how to sort containers and what sizes they should be. Most containers are either 20ft or 40ft long.
[pdf] Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh. Technological advancements are dramatically improving solar storage container performance while reducing costs.
[pdf] The National Electric Code (NEC), published by the National Fire Protection Association (NFPA) and officially designated as NFPA 70, sets the standards for electrical safety and performance and provides a comprehensive framework that photovoltaic and other renewable energy projects must follow.
