The US solar sector lost US$4.6 billion in 2023, marking the fifth consecutive year that average power loss has increased, rising from 1.61% in 2019 to US $4,696/MWDC, according to Raptor Maps. This means that the average revenue loss for solar operators has almost tripled from US$1,692/MWdc in 2019, and the overall cost of the solar sector has increased. The majority of power losses are due to system-level faults, rather than specific solar modules, not specific modules. Module-related faults accounted for just 4.5% of all power losses in 20th, although this percentage has increased from just over 1.5%. The report also highlighted differences in power loss in five US regions, with the north-east and south-east posting the highest figures of revenue loss at US$6,108/MW DC and US$5,784/MW respectively. There is a notable discrepancy in the value of revenue lost at sites of different sizes and a significant discrepancy in revenue lost per MW.
