irradiance

Understanding year-on-year solar radiation variability is critical for optimising solar projects, particularly amid climate change.

Keith McIntosh of PV Lighthouse describes why energy yield forecasts are underestimated, and how the PV industry is improving forecasts.

PV systems combining bifacial and tracker technologies deliver the lowest-cost PV-generated electricity in most parts of the world.

PV modelling relies on the assumption of 99% availability for forecasting, but the adoption of a more realistic metric would improve finances.

Rising pollution in India, is impacting the annual revenue of Indian solar power plants, industry analysts tell PV Tech Premium.

The rapid emergence of new PV technologies such as bifacial has in some cases outpaced the evolution of suitable technical and regulatory specifications.

As PV projects become more and more common in the Nordics, wind players like OX2 are entering the solar market with large-scale projects.

While bifacial modules promise advantages in power production, they can create complex performance monitoring challenges. That will need to be resolved if project production uncertainties are expected to remain at levels and expectations currently set with the deployment of mono-facial modules, write Ajay Singh and Derek Jones of Campbell Scientific Inc.

A steep decline in solar irradiance in Spain earlier this year highlights the need for an interconnected European grid and increased investments in forecasting, according to PV data firm Solargis.

The impact of solar resource variability on several key global PV markets including India, Australia and North America has been revealed by a ten-year analysis from solar irradiance consultancy Solargis that illustrates “significant deviations from long-term averages”.
