BIG SUN's iPV Tracker builds further & stronger momentum

Taiwan based PV solution provider, BIG SUN Group has recently synergized its innovative iPV Tracker, a Dual axis tracker, with a bifacial module resulting up to a 100% power generation gain over a conventional fixed tilt system.

HSINCHU, Taiwan, Aug. 31, 2017 /PRNewswire/ -- By 2021, solar tracker installations will grow to an amount of 37.7 gigawatts and account for nearly half of all ground-mount solar systems, according to GTM Research. The booming of this niche market is self-evident since Warren Buffett is also taking the lead in investing in the Dual Axis Tracking system.


Taiwan based PV solution provider, BIG SUN Group has recently synergized its innovative iPV Tracker, a Dual axis tracker, with a bifacial module resulting up to a 100% power generation gain over a conventional fixed tilt system.

On the rear side of the bifacial module power generator, iPV tracker's unique 360 degree, universal axis design with a slim cable drawn driving mechanism, has much reduced the shading impact from the sizable Linear actuator and slewing drive employed by the conventional dual axis trackers.

Moreover, to eliminate any shading induced from the module mounting frame, Summer Luo, the Chairman of BIG SUN, also the inventor of iPV Tracker, has redesigned the rear supporting frame so as to match exactly to the frame dimension of any module. "In addition, the iPV Tracker is tall enough to have the sunlight reflected and absorbed onto the rear side of the bifacial module. These features have enabled the realization of the benefits of bifacial modules, especially in snow season."

A worthy PV product must be capable of not only enduring various climate zones and different seasons, but also accommodating the extreme weather resulted from the climate change. The iPV Tracker is the only robust dual axis tracker that can fully accommodate extreme weather with special features as "Wind Resistant", "Snow Removal", "Dust Removal", "Flood Avoidance" and "Back Tracking". The patented back tracking mechanism has enabled the iPV Tracker a more dense installation yielding 15-50% more on land utilization.

Another innovative energy monitoring system, iPVita, designed by BIG SUN, can furnish power generation status, environmental sensor feedback (irradiance, wind speed, temperature), operation efficiency and remote control, at just a click away on your mobile device. In particular, the auto abnormality alert system has in itself differentiated specific hardware failure, system down, network issues or a communication breakdown issue. Such diagnosis function combined with the auto abnormality dispatching/tracing function of iPVita has facilitated the iPV Trackers to reach > 99.9% availability in field operation.

BIG SUN continuously enhances the design of iPV Tracker, besides flexible module platform frame design to match to any module frame dimension to avoid shading on bifacial modules, another significant enhancement this year is the unleash of the 2nd generation wheel axis structure and spring design. This much simplified design has prevented the slipping of steel cable rendering much less noise than before. Also the upgraded design of spring in parallel connection with steel chains has further reinforced a more robust driving mechanism.

BIG SUN has also unveiled a scale up and cost down version of 12Kw tracker suited for sites without strong wind. This can accommodate 40 panels with a 60 cells module or 32 panels with a 72 cells module. This is best applied to large scale power plants with lower LCOE, while maintaining reliable & robust operation. As Luo commented, "The PV industry now is seeking a wide range of balance while the profitability is evidently most pursued and 12kw iPV Tracker is 100% ready for this end."

In Solar Power International 2017 (SPI in Las Vegas, USA), BIG SUN has the privilege to jointly exhibit advanced modules from Longi Solar, China and First Solar, USA mounted on iPV tracker to demonstrate the flexibility of its accommodation. You are cordially welcomed to visit our booth at #503 for further information and discussion.
