Opinion & Analysis


Solar dimming and brightening, and PV power plant output performance

Reliable assessment of the local solar radiation resource is a major component of large-scale PV power plant project development and financing. This assessment is usually based on the assumption that the long-term average annual solar radiation from previous years is not significantly different from the expected future solar resource availability. In many areas of the globe, the solar radiation availability in 2023 was considerably higher (up to 10-12%) than the long-term average, and this might be overshadowing the fact that a large fraction of utility-scale PV power plants is undeperforming.

2024 Outlook: What could La Niña mean for US solar this year?

In a new weekly update for pv magazine, Solcast, a DNV company, describes the possible consequences for PV plan and grid operators of a possible switch to La Niña conditions in North America.

In contrast, the Atlantic coast of the USA has historically seen up to 5-10% above-average irradiance during summer months in previous La Niña events.
