Efficiency Of Mono And Polycrystalline Solar Panels

But as you climb the wattage efficiency scale poly panels are left behind and mono panels break above 17 efficiency.

Efficiency of mono and polycrystalline solar panels. The efficiency of polycrystalline solar panels is somewhat lower but the benefit for customers is that this option is more affordable. It is mainly used in large scale commercial applications. In addition polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels. Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient.

Polycrystalline solar panels generally have lower efficiencies than monocrystalline options but their advantage is a lower price point. But bear in mind that this specification is notoriously unreliable if you rely on the manufacturers to measure it. Monocrystalline solar cells are more efficient because they are cut from a single source of silicon. However thanks to new technologies polycrystalline panels are now much closer in efficiency to monocrystalline solar panels than they have been in the past.

The mono solar panel is a bit better according to the manufacturer s spec. While installing solar panel it is like a headache to choose from monocrystalline vs. In addition when you seek polycrystalline solar panels for sale the sellers may highlight the blue hue of these panels compared to the monocrystalline panels black hue. Because of the lower efficiency rate they are not as space efficient since they produce less power per square foot.

This is a measure of how much the power drops when the panel gets hot solar panels like light but don t like heat. Polycrystalline solar panels are also made from silicon. Polycrystalline panels have lower efficiency rates typically in the 13 16 range. Monocrystalline panels have higher efficiencies in the range of 15 20.

Polycrystalline panel efficiency ratings will typically range from 15 to 17. Monocrystalline panels are more efficient reaching efficiencies between 15 20 on average while polycrystalline panels are only 13 16 efficient. This crystal structure makes the efficiency rate of polycrystalline panels lower than monocrystalline panels. You would need a much larger array of polycrystalline panels to produce the same amount of energy than if you used monocrystalline which may not work for households with limited roof space.

However once we get into the range of 270 275 watts efficiency of the poly panels are about the same as the monocrystalline panels around 16 5 to 16 9. For this reason if maximising electricity generation and reducing costs is a priority monocrystalline are likely to be slightly more effective.
