Key takeaways from Bulgaria’s RE-Source Southeast Conference

The first day of the RE-Source Southeast Conference in Sofia, Bulgaria, this week underscored European and regional interest in renewable-energy projects based on corporate power purchase agreements (PPAs). Negative or very low electricity prices in European electricity markets affect the appetite for such projects, but the solution for investors and policymakers is to approach the issue systematically.

Building back bigger

Already 2024 is shaping up to be another record year for solar installations. In Europe, projects are getting bigger as increasing difficulty with obtaining a grid connection makes smaller systems unviable. pv magazine recently caught up with Bernhard Suchland, CEO of Germany/Bulgaria based project services provider Sunotec, for a look a closer look at this and other trends in the large-scale PV segment.

New model to predict defrost cycles, behavior of air-sourced heat pumps in cold weather

UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The results of their simulation showed a strong relationship between the number of defrost cycles and the ambient temperature.
