Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.
European renewables, including Spanish solar, made big gains as energy demand recovered before the second wave of Covid infections. Nuclear was a notable loser, in part because clean energy volumes in the north of the continent drove down power prices sufficiently to make reactors uncompetitive.
The German renewable energy company has completed two more projects, totaling 29.2 MW, in the country.
Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that is claimed to reduce cleaning cost by around 60%. The anti-reflective and anti-corrosive coating is also said to mitigate potential-induced degradation (PID).
Researchers in the Netherlands and Singapore have measured irradiance-weighted average temperatures of floating PV systems in both countries and have compared the results with reference rooftop and ground-mounted PV systems. They have discovered that floating PV systems with open structures, which allow wind to pass beneath the modules, can provide a higher heat loss coefficient.
The Netherlands Authority for Consumers & Markets has established that the first-come, first-served principle applied by grid operators is the correct approach to manage current grid congestion. The decision was taken to resolve a legal dispute between Liander and an agricultural entrepreneur that was denied grid access for a PV project.
Dutch contractor Heijmans has deployed a solar noise barrier to test three different PV module technologies, including cadmium telluride, CIGS, and crystalline products. Initial analysis has shown unexpectedly low returns, due to the rates at which the installation is selling power to the grid. But high levels of self-consumption could make such designs competitive with conventional noise barriers.
Dutch researchers have shown that bifacial floating PV arrays do not benefit significantly from sunlight reflected from the water, and claim that the water only reduces panel temperatures by a small amount. Bird droppings may also affect system performance, but floating PV could achieve a lower LCoE than ground-mounted arrays if such issues are addressed, they say.
