Which is better monocrystalline or polycrystalline solar panels?

Whilst monocrystalline solar panels are preferred due to their efficiency, polycrystalline solar panels are popular as they are more affordable. However, you should consider all the pros and cons as mentioned in this guide on Monocrystalline vs Polycrystalline solar panels before making your decision.

What are polycrystalline solar panels?

Polycrystalline panels, sometimes referred to as ‘multicrystalline panels’, are popular among homeowners looking to install solar panels on a budget. Similar to monocrystalline panels, polycrystalline panels are made of silicon solar cells. However, the cooling process is different, which causes multiple crystals to form, as opposed to one.

Why are polycrystalline solar panels less efficient?

For this reason, they are called “poly” or multi crystalline. The electrons in each cell will have less space to move because of many crystals in a cell. Therefore, the efficiency ratings of polycrystalline solar panels are relatively lower. Temperature Coeff.

Are polycrystalline solar panels the cheapest option?

Historically, polycrystalline panels have been the cheapest option for homeowners going solar, without majorly sacrificing panel performance. Low prices allowed polycrystalline panels to make up a significant market share in residential solar installations between 2012 and 2016.

Are monocrystalline solar panels expensive?

Monocrystalline solar panels come under the category of premium solar panels and are expensive. This is because of the single silicon crystal used in making the cells and the complex manufacturing process.

How does temperature affect polycrystalline solar panels efficiency?

Most monocrystalline solar cells have a temperature coefficient of around -0.3% / C to -0.5% / C. So when the temperature rises 1 degree Celsius or 32 degrees Fahrenheit, the monocrystalline solar cell will temporarily lose 0.3% to 0.5% of its efficiency.
