Mono Vs Poly Solar Panels

Posted on Monday, August 12th, 2014

What is the difference between Mono-crystalline and Poly-crystalline solar panels?

Monocrystalline vs Polycrystalline solar panels LeicestershireFirst things first, let’s break it down.

The mono-crystalline panels are made out of cells from pure silicon.

The difference between mono-crystalline and poly-crystalline solar cells is simply that Mono is produced from a single crystal of silicon whilst Poly is produced from a piece of silicon consisting of many crystals. Mono Panels take more time to manufacture and this is reflected on the price. Usually Mono is pricier than the Poly panel.

Mono modules have a darker appearance with rounded cells whereas Poly modules have a less uniform appearance since they are made up of many crystals. This also means that the Poly Modules absorb slightly less solar energy and produce slightly less electricity, hence the cheaper price.

Mono-crystalline solar panels will typically have higher efficiency rates (15-20%), converting energy particularly well in low-light conditions. For a limited area, Mono would be the best option since usually they have higher efficiency. Although As technology progresses, the gap between mono and poly continues to shrink.

Poly-crystalline cells are known to function better than mono-crystalline under high-heat circumstances however less efficient in low light conditions.

 

Mono Pros:

Highly efficient

Uniform appearance

Performs well in low-light conditions

Ideal for areas with space constraints.

They have been around a long time, proving their longevity and durability usually comes with a 25 year warranty.

Mono Cons:

Slightly more expensive

Sensitive to shade.

 

Poly Pros:

They waste less amount of silicon hence being more budget friendly.

Poly Cons:

Lower efficiency

Performs less in low-light conditions

Panels require more space when installed

So the ultimate question is, which panel should you go for?

Now that we narrowed down the pros and cons for each solar panel, other factors come into place when making a decision, such as the manufacturer. Different manufacturers carry different qualities and at the end of the day if the solar panels come with a 25 year guarantee you would need a reputable manufacturer that has been in the industry for long enough to know that he will honour the guarantee when it comes down to it 25 years down the line.

The installation team is also something you should look into; you don’t want to just get the best solar Panel but also need to have the whole process concerning the design and installation.

Now back to the original argument, Mono VS Poly. If you are limited with space, you are more likely to benefit from the Mono-crystalline panel since they take up less space whilst producing more.

Even though Mono-crystalline has a better reputation for being more efficient, the Poly-crystalline solar panels have come on leaps and bounds as technology has progressed over the past few years. The climate where you reside, budget, roof space and aesthetic preference are all factors one would need to take into accounts before making an official decision but we mostly side with Mono solar panels at Renergy Solutions due to the efficiency and experience have with the great performance of Monocrystalline solar panels.

Most of the solar panels we have fitted in Leicestershire and around the midlands have been all black monocrystalline system. Please view our gallery to see examples of our work.
