Inverter Startup Delays: A 1.88% Drain on Solar Plant Revenue

Leave a Comment / News /

Delayed Inverter Startup Can Reduce a Solar Plant’s Annual Energy Yield by 1.88% When solar asset owners think about performance losses, the usual suspects come to mind: soiling, module degradation, shading, and inverter downtime. But there is a quieter, more insidious source of lost energy that often goes unnoticed — delayed inverter startup after sunrise. Brazilian

Ten reasons why small-scale, non-utility solar is important

Leave a Comment / News /

Solar projects can generally be placed in two buckets: they are either large utility-scale ground-mounted projects connected to the grid, or they are smaller, distributed projects, typically 20 MW in capacity or less.  In California, and many other U.S. states, smaller, distributed projects, particularly ones located behind the meter, are under attack from utilities and

End of net metering not a threat to residential solar profitability

Leave a Comment / News /

Two major Dutch research institutes, CE Delft and the Netherlands Organisation for Applied Scientific Research (TNO), have conducted a study for several renewable energy associations to assess the impact of scrapping the country’s net metering scheme in early 2027 on residential PV system profitability. The report suggests that even without the ability to sell excess power to the grid, PV system
