Perc cell technology defines a solar cell architecture that differs from the standard cell architecture that has been in use for three decades and that is usually featured in all photovoltaic manuals.
2018 which solar panels use perc.
This stress can cause the ribbons to disconnect from the cell or the cells to crack diminishing power production for the entire system.
Not all solar panel manufacturers use perc technology but certain installers may carry perc products.
From top to rear.
Jinko solar eagle perc 60 jinkosolar is number one on the list and going through their list of solar panels the eagleperc 60 is the top residential product the panel tops out at 18 3.
News item from longi.
Mono perc may not be suitable for all types of solar projects.
I m not talking about the labour efficiencies they receive.
Most tier 1 module manufacturers.
However they are optimal for residential rooftop installations where faster roi and lower installation costs are the driving factors.
Perc panels have a higher energy density per square foot and perform well under low light conditions and high temperatures.
Update 16th april 2019.
Most solar panels including those with perc use metal ribbons to connect the cells.
Those metal ribbons expand in heat and contract in the cold.
Many perc panels have suffered from letid deterioration problems since this article was written.
Panels incorporating perc technology give more freedom to developers and designers especially when dealing with unorthodox spaces or locations that were once thought to be less than desirable for solar.
Thanks to perc solar cells we can now get affordable panels at higher wattage.
Solar panels degrade over time.
Perc cells enabled access to module with higher power ratings of up to 370 w for a 72 cell module and power ratings could cross 400 wp in the near future.
Solar panel manufacturers crave efficiency.
Perc is a technology that increases perc solar cell efficiency in the more affordable p type silicon modules.
As of today the vast majority of crystalline solar cells produced follow the structure presented hereunder.
The increase in demand for high efficiency panels is inevitably pushing the consumers to adopt mono perc panels.
This article here goes into the problem and this article on the mc electrical blog covers it in detail and gives information on which perc panels are resistant to letid.
Longi solar s commitment is that while creating new records for module efficiency the company will continue to adopt new module technologies in 2018 to realize higher module efficiency focus on both high efficiency and high power create greater value for the pv application market and accelerate the advent of grid parity.
Undoubtedly there has been a lot of excitement and anticipation around perc solar cell technology with many solar cell manufacturers enthusiastically promoting it as a game changing technology.
