Maximizing the potential of PV irrigation in Spain’s ‘Sea of Plastic’
Spanish researchers have developed an analytical model to optimize the operation of PV water pumping systems. They say simultaneously irrigating different parts of a farm could help minimize costs and maximize energy use. The model was tested on an olive farm divided into four zones in the Spanish province of Almería.

LBIC: Seeing solar potential
Digital imagery with laser lighting has been utilized to quantify a solar cell's performance for a while through a procedure called light beam induced current (LBIC) mapping. But, because of the serial nature of image processing, it has not been easy to do fast. Danish start-up InfinityPV states it has used a method which can expedite the LBIC rate by over 10 million times.
