Energy Valuation

Energy Valuation

Clean Power Research pioneered many of the methods currently used to quantify the value of distributed PV generation from the perspective of utilities and PV system owners. The company’s energy valuation research examines a range of topics such as the value of solar power generation in the U.S., capturing capacity-related benefits of variable energy resources, and the use of distributed generation to reduce transmission and distribution costs.

Enabling the future of solar: Bifacial PV modeling takes center stage in SolarAnywhere API, powered by industry-trusted pvlib models

According to the World Energy Outlook report by the International Energy Agency (IEA), global annual solar PV capacity growth is expected to more than quadruple in 2030 to 650 GW. Nearly 50% of the global solar capacity is slated to come from utility-scale installations. One trend that is expected to dominate new commercial and utility-scale […]
