Auswell energy goes into more depth about which solar panel type is best for you.
Monocrystalline
To recap, monocrystalline panels consist of single-crystal silicon cells. The manufacturing process is more involved and complicated because the silicon is synthesised in a lab to produce pure silicon.
Polycrystalline
Polycrystalline panels consist of multiple silicon crystals. This is because the silicon is melted and poured into a mould, and the cooling process produces multiple crystals.
Points of Comparison
1. Cost
Monocrystalline solar panels are more expensive than polycrystalline due to the manufacturing process and higher performance of the panels.
SWITCH TO SOLAR & SAVE
Polycrystalline is the more cost-effective option. Although you will be sacrificing performance, as long as you’re meeting your electricity requirements with your PV system, you will be saving money overall.

2. Efficiency
Monocrystalline panels are the most efficient type of solar panels with about 17-22% efficiency rating. Due to the way the cells inside the panels are manufactured, electrons that break off from the sun’s rays easily flow through the cells. Monocrystalline panels also have a higher power capacity rating with some models exceeding 540w.
Polycrystalline panels are moderately less efficient with 15-17% efficiency rating. Because the cells within don’t have uniform crystals, electrons get trapped within the cells. Polycrystalline panels also have a lower output ranging from 240-300 watts and are less readily available overall because of this.
3. Lifespan
The type has no impact on the lifespan of solar panels. Silicon cells will last for 25+ years as long as you take care of your solar panel system. For more information on solar panel longevity, read our post: How long will my solar system last?
4. Temperature Coefficient
The temperature coefficient of a solar panel determines how well the solar panels will perform in warmer weather. Monocrystalline outperforms polycrystalline as it performs better in higher temperatures.
5. Aesthetic
Monocrystalline panels appear black due to the way the cells are manufactured. Polycrystalline panels have a blue hue because of the un-uniform crystal structure.
Which is the best type for you?
The best solar panel type largely depends on your budget and space. If you have a smaller budget but more space to install solar panels, then polycrystalline panels could be the way to go. If you have less space and less budget constraints, then monocrystalline would be the best option.
The best solar panel type also depends on your aesthetic preferences. Monocrystalline panels have more of a subtle aesthetic on darker roofs.
Nevertheless, whichever solar panel type you choose you will be saving money on your electricity bill in the long run.
