Mono Perc Vs Poly Solar Panels

Solar panel manufacturers crave efficiency.

Mono perc vs poly solar panels.

Hyundai rg series his default. Many perc panels have suffered from letid deterioration problems since this article was written. The older of the two mono panels are the most developed type of photovoltaic panel cells. Jinko solar eagle perc 60m 280 300default.

I m not talking about the labour efficiencies they receive. Monocrystalline solar cells are more efficient because they are cut from a single source of silicon. Image one half cut cell image 2 standard mono perc solar panel. Canadian solar hiku mono.

Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together. So first off it s important to know a few basics. Thin film technology costs less than mono or poly panels but is also less efficient. Monocrystalline solar panels a mono solar panel is made with high quality silicon manufactured with intricate patterns across the surface making them easy to differentiate from poly solar panels.

On the other hand passivated emitter and rear cell perc uses dielectric passivation film on the rear surface of the cells. Thin film solar panels are the cheapest but have the lowest efficiency rating and require a lot of space to meet your energy needs. Polycrystalline solar panels are cheaper than monocrystalline panels however they are less efficient and aren t as aesthetically pleasing. 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.

It creates more pathways for power to get to the inverter. Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient.

The main difference between the two technologies is the type of silicon solar cell they use. A half cut cell doubles this amount to 120 in the same size solar panel. Perc is an innovation that is currently available in the form of mono and poly cells. So what and who cares.

It is mainly used in large scale commercial applications.
