Are monocrystalline solar panels better than polycrystalline panels?

Monocrystalline panels are usually more efficient than polycrystalline panels. However, they also usually come at a higher price. When you evaluate solar panels for your photovoltaic (PV) system, you'll encounter two main categories of panels: monocrystalline solar panels (mono) and polycrystalline solar panels (poly).

What is a monocrystalline solar panel?

A monocrystalline solar panel comprises high-quality, single-crystal silicon cells. As the cell is constituted of a single silicon crystal, there is more space for electrons to move for a better electricity flow. As a result, they are more efficient than their polycrystalline cell counterparts.

What are polycrystalline solar panels?

Polycrystalline solar panels have blue-colored cells made of multiple silicon crystals melted together. These panels are often a bit less efficient but are more affordable. Homeowners can receive the federal solar tax credit no matter what type of solar panels they choose.

How long do monocrystalline solar panels last?

Both monocrystalline and polycrystalline panels will produce electricity efficiently for 25 years or more. Like efficiency, monocrystalline solar panels tend to outperform polycrystalline models regarding temperature coefficient.

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. How Temperature Affects Polycrystalline Solar Panels Efficiency?

What are the disadvantages of monocrystalline solar panels?

Monocrystalline solar panels have numerous advantages but one of their main disadvantages is the high initial cost. Among all types of PV solar panels types, monocrystalline is definitely the most expensive one to produce.
