Efficiency Of Mono And Polycrystalline Solar Panels

Polycrystalline solar panels generally have lower efficiencies than monocrystalline options but their advantage is a lower price point.

Efficiency of mono and polycrystalline solar panels.

Polycrystalline solar panels are also made from silicon. While installing solar panel it is like a headache to choose from monocrystalline vs. However thanks to new technologies polycrystalline panels are now much closer in efficiency to monocrystalline solar panels than they have been in the past. Polycrystalline panels have about 13 to 16 efficiency while monocrystalline panels have an efficiency rate of anywhere from 15 to 20.

Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient. This crystal structure makes the efficiency rate of polycrystalline panels lower than monocrystalline panels. Monocrystalline solar cells are more efficient because they are cut from a single source of silicon. Because of the lower efficiency rate they are not as space efficient since they produce less power per square foot.

Monocrystalline panels are more efficient reaching efficiencies between 15 20 on average while polycrystalline panels are only 13 16 efficient. The mono solar panel is a bit better according to the manufacturer s spec. Both monocrystalline and polycrystalline are solar power panel made of silicon and work on same. 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.

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. Thin film technology costs less than mono or poly panels but is also less efficient. Monocrystalline panels have higher efficiencies in the range of 15 20. The efficiency of polycrystalline solar panels is somewhat lower but the benefit for customers is that this option is more affordable.

For this reason if maximising electricity generation and reducing costs is a priority monocrystalline are likely to be slightly more effective. It is mainly used in large scale commercial applications. This is a measure of how much the power drops when the panel gets hot solar panels like light but don t like heat. But as you climb the wattage efficiency scale poly panels are left behind and mono panels break above 17 efficiency.

Polycrystalline panels have lower efficiency rates typically in the 13 16 range. Polycrystalline panel efficiency ratings will typically range from 15 to 17.
