Perc battery module model specifications

Should I use 60 Cell PERC modules with MPPT controllers?

In accordance with past recommendations, Morningstar recommends using 60 cell PERC modules with MPPT controllers as long as there are enough modules in series to fully charge the battery bank. For 24V battery banks, this means at least two 60 cell modules in Series are required.

What is a PERC solar cell?

To reduce efficiency losses, researchers in the solar industry developed the PERC solar cell. PERC technology was first described in the University of New South Wales in 1983 but officially registered in a paper in 1989.

What is PERC technology?

Other advanced panel technologies PERC is only one of the available technologies to improve efficiency and applications for solar panels. There are other advanced technologies like Interdigitated Back Contact (IBC) and Bifacial Solar Cell (BSC) technology. Manufacturers can use either one or even combine PERC with IBC or BSC.

Do PERC modules have higher voltage ratings?

The 5-15% higher voltage ratings of the new PERC modules can have a big effect on this. 36 cell and 72 cell PERC modules have higher voltage ratings than what was considered to be the standard with traditional nominal voltage modules in the past.

Can PERC modules be used with a PWM controller?

36 and 72 cell PERC modules can still be used at nominal voltage with an equivalent matching battery voltage of 12V or 24V respectively, with both PWM and MPPT controllers. MPPT Boost gains are now even more significant compared to a PWM controller.

Who makes PERC panels?

PERC is high on the hit list of record efficiencies. In the last 12 months, the world record was broken 6 times. Today’s highest efficiency PERC cell of 23.95% was made by JinkoSolar, followed by a 23.6% cell from LONGi. When it comes to production of PERC panels, the general metric is rather module power than cell efficiency.
