PV Hardware USA (PVH), a photo voltaic tracker producer, has developed Diffuse Management, a photo voltaic tracker algorithm designed to extend photo voltaic plant era throughout overcast situations, doubtlessly growing manufacturing by as much as 20% on some days in comparison with conventional solar monitoring algorithms.

“Solar monitoring is most frequently primarily based on pure geometry, the place the solar’s place is adopted by transferring the trackers perpendicular to the primary path of the rays,” stated Oscar Cabrero, electronics and management supervisor of PVH. “Nevertheless, we all know there’s power to be collected surrounding the photovoltaic modules. When diffuse gentle predominates the setting, our superior algorithm calculates the optimum panel inclination tilt to seize this power.”
Whereas photo voltaic panels nonetheless generate electrical energy utilizing conventional photo voltaic tracker expertise throughout cloudy climate, they produce considerably much less energy in comparison with sunny days. Utilizing real-time climate information captured by sensors positioned inside the photo voltaic plant, the Diffuse Management algorithm robotically calculates the photo voltaic panel inclination tilt required to seize extra power throughout wet or cloudy situations. To keep away from pointless power use, the algorithm will be configured to cut back motor consumption throughout operation, thereby maximizing productiveness positive aspects.
“Utilizing new fashions of how photo voltaic power is captured, we now perceive that measuring environmental irradiances is one of the best ways to calculate a panel’s inclination tilt throughout inclement climate,” Cabrero stated. “With this new understanding, PVH was capable of develop the Diffuse Management algorithm.”
PVH carried out a collection of exams to validate the efficiency of the Diffuse Management algorithm, together with empirical testing of the expertise over a number of months and a side-by-side comparability between two actual contiguous photo voltaic vegetation the place normal photo voltaic monitoring and the Diffuse Management mannequin have been applied. Findings revealed that in diffuse irradiance situations, the Diffuse Management mannequin captured extra irradiance, leading to the next manufacturing and power acquire. A white paper detailing the expertise and the testing confirming its efficacy is obtainable to obtain here.
