6 Properties Of Monocrystalline And Polycrystalline Solar Panels


Solar panels, alternately called solar electric panels, is an assembly of photo-voltaic cell modules that are mounted in a framework for rooftop installation. Solar panels utilize sunlight as their main source of energy for generating direct current electricity. 

They come in various types, shapes,, and sizes varying according to performance, longevity, design,, and other aspects. The two most common categories of solar panels available in the market are (i) Monocrystalline, and (ii) Polycrystalline.

Different properties to look at while choosing between monocrystalline vs polycrystalline

The following section gives an overview of the factors you should consider before finalizing a monocrystalline vs polycrystalline solar panel for your home or business:

  1.  Cost

The first and foremost aspect to choose between monocrystalline vs polycrystalline is cost. While monocrystalline solar panels are made of a single silicon crystal involving a complex manufacturing procedure, it is classified under the ‘premium’ range and is expensive. 

Polycrystalline, on the other hand, is made simply by melting off silicon fragments cut into thin wafers. Due to their ease of manufacturing, polycrystalline solar panels are more budget-friendly.

  1. Temperature Coefficient & Efficiency

Monocrystalline tends to allow more space for electron flow thus generating huge amounts of energy during hotter temperatures whereas polycrystalline requires more panels for generating the same output. Hence, between monocrystalline vs polycrystalline solar panels, monocrystalline provides greater efficiency than polycrystalline.  

  1. Power Capacity

Watt peak (Wp) is the measure of power rating of solar panels depicting the peak DC that can be generated by the solar panel under standard conditions. Different types of solar panels vary in Wp wherein Mono-PERC Half Cut panels combining monocrystalline Half Cut cells and PERC technology gives a 540 Wp DC power rating. Polycrystalline panels are typically available with 320 to 370 Wp power capacity. For monocrystalline vs polycrystalline, the former is suited for commercial use because of its higher power capacity while the latter is good for homes.

  1. Space availability

Space availability is a big factor when finalizing between monocrystalline and polycrystalline solar panels. If you have a limited rooftop space for installation, you can consider monocrystalline as about 50% to 60% high power capacity panels can fit in that space. However, if you have ample space, you can opt for polycrystalline solar panels that are larger and more economical in the long run.

  1. Longevity

Having an average lifespan of more than 25 years, both monocrystalline and polycrystalline solar panels undergo annual degradation. While mono reduces by 0.55%, poly decreases 0.7% annually in the power rating capacities. 

After 25 long years of operation, monocrystalline panels lose 15% while polycrystalline reduces by 19% in power rating. To choose the right one, you should consider companies offering better power production warranty.

  1. Design

Design and appearance may not be the first factors that come into your mind when buying a solar panel, but it does matter a lot if you are planning an installation for business purposes. Monocrystalline solar panels have ornamental octagonal shapes with black and dark blue hues whereas polycrystalline panels are blue-hued and square. 

So, if you want something aesthetically pleasing, monocrystalline solar panels are a great choice due to their sleek design but if you prefer simplicity, you can consider polycrystalline solar panels.

The prime deciding factor

If you are still hesitant about opting between monocrystalline and polycrystalline solar panels, you should remember that the prime deciding factor is your personal preference. Only you know best what kind of performance, characteristics, output,, and usage you are looking for, hence you can choose the right option by thoughtful consideration of the above-discussed factors. 

Be careful to check the pros and cons of monocrystalline vs polycrystalline solar panels before you head to the market for buying one.
