Recently, Our company has successfully developed an Intelligent PV junction boxSmart box-Cwhich is
special used for Solar PV panels. This kind of junction box uses the most advancedCloud computing and
the Internet of thingstechnology,and carries a software system for point-to-point PV panels monitoring,
analysis, power optimization and fault diagnosis; It applies sensor technology to remote extracting and
monitoring operation parameters of each solar photovoltaic panel; and uses the
MaximumPowerPointTracking (MPPT) to optimize the power output of single panel in a complex climate
environment; and it also can raise the whole PV power generation efficiency, and reduce the cost of power
generation. As is well known, the junction box carried by traditional PV panels is only used for PV panels’
connection and current transmission. However, in the past 25 years’ history of using PV system, its
generating efficiency were often affected by the chimneys, tree bowers, birds droppings, black clouds and
dusts, and fire hazard were correspondingly increased. Some international authoritative photovoltaic
experts have done a study and show that, in the severe cases, if 10% of the power generation area of PV
system is shaded, maximum loss of power in the whole system could be as high as 60%. Meanwhile, PV
station would lose 9%-11.5% of the total power because of various integrated factors in normal use
environment even if there are not special factors. It would be a potential safety hazard and greatly reduced
the generate electricity benefit of PV system. This manufacture will solve the problem and significantly
improve power efficiency.
