Prostar PPS150W 150 watt 12 volt polycrystalline solar panel price |

Prostar PPS150W 150 watt 12 volt polycrystalline solar panel (sometimes called polycrystalline solar panels) is made from polycrystalline solar cells, but polycrystalline solar cells are cheaper to make than monocrystalline cells. To make a polycrystalline ingot, you simply melt a load of silicon and then pour the molten liquid into a big box where it solidifies. This is a lot simpler than growing a monocrystalline ingot on a multi million dollar crystal growth machine from a tiny seed over days or weeks until you have a beautiful shiny cylinder made of a single crystal of silicon!

Prostar PPS150W 150 watt 12 volt polycrystalline solar panel is particularly suitable for utility scale installations. Thanks to the excellent temperature coefficient, a high yield is guaranteed also at high temperatures.

The only real differences between a mono and polycrystalline solar cell are:

1) Polycrystalline solar cells are perfectly square;
2) Polycrystalline solar cells have grain boundaries (clearly visible) which slightly reduce the solar efficiency by making it a bit harder for the electrons to flow.

So does mean Prostar PPS150W 150 watt 12 volt polycrystalline solar panel is priceinferior to monocrystalline? Not really, because the multicrystalline cells’ square shape means that when they are laid up into the panel, there is no wasted space. This makes the efficiency of a typical polycrystalline solar panel almost identical to a typical monocrystalline module these days.

Polycrystalline cells were previously thought to be inferior to Monocrystalline because they were slightly less efficient, however, because of the cheaper method by which they can be produced coupled with only slightly lower efficiencies they have become the dominant technology on the residential solar panels market.
