Mono Vs. Poly Solar Panels
One of the first questions to consider when shopping for solar panels for your home or business is whether you should pick mono or poly solar panels. Both mono and poly solar panels are made of silicon, have silicon molded into crystalline forms, but there are some major differences between the two types, and each has their advantages and disadvantages.
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. The older of the two, mono panels are the most developed type of photovoltaic panel cells.
Advantages of Mono Solar Panels
- Mono panels are the most efficient since they’re made with high-quality silicon. They typically perform better than polycrystalline alternatives, albeit by a small amount.
- Because of their quality, they also tend to last the longest. Many installers offer a warranty of at least 25 years, with most panels poised to last beyond that.
- Mono solar panels make the most energy for the space they take up, thanks to their high efficiency.
Disadvantages of Mono Solar Panels
- Since they’re the highest-quality, they’re the most expensive.
- Due to the way mono panels are wired, covering one section can lead to the panel not working properly. This can be something as simple as a tree’s shade or snow landing on the panel, but there are wiring options to avoid this issue.
- If you’re concerned about waste as well as energy, a mono solar panel unfortunately creates more silicon waste than other types of panels.
Polycrystalline Solar Panels
Poly solar panels are a newer and have a simpler manufacturing process than monocrystalline panels. The silicon used to make them is simply poured into a mold and allowed to cool, and then cut into squares.
Advantages of Poly Panels
- They’re cheaper than mono panels since they aren’t made through an intensive manufacturing process and use less silicon. They also produce less waste as a result.
- In hotter weather, poly panels will have a relatively similar energy output as with cooler temperatures. Performance won’t be affected thanks to this, but the output is usually negligent when compared to mono panels.
Disadvantages of Poly Solar Panels
- They are less energy-efficient than poly panels, although not to a detrimental degree.
- You’ll need to cover a larger amount of space for the same energy production as a mono panel.
The solar panel that’s best for you depends on your home or business special needs. The usable space on your roof and current rebates and incentives will drive your choice of which solar panel to choose.
