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.

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 long does a monocrystalline solar panel last?

Monocrystalline solar panel manufacturers will usually offer a 25-year warranty because of the longer lifespan of the product. On this parameter of lifespan, polycrystalline solar panels are not very different, but the warranty period offered by the manufacturers may vary.

How are monocrystalline solar panels made?

Monocrystalline solar panels are made from a single, continuous silicon crystal. This manufacturing process results in a panel comprised of silicon wafers that have a consistent, uniform molecular structure. When sunlight hits the monocrystalline cells, the photons catalyze the uniform silicon atoms to dislodge and excite electrons.
