Many solar panels manufacturers promise different results from lower prices to better aesthetics. But when selecting solar panels, key factors to consider include the panel efficiency, durability and warranty.
-
Panel efficiency:
Efficiency refers to how well a solar panel converts sunlight into electricity. Higher efficiency panels are more valuable in areas with limited space.
Monocrystalline: Monocrystalline panels are known for their high efficiency and are often the preferred choice for residential installations. They are made from a single crystal of silicon, resulting in higher efficiency and a more uniform appearance.
Polycrystalline: Polycrystalline panels are made from multiple silicon crystals, making them less expensive than monocrystalline panels but also slightly less efficient.
Thin-film: Thin-film panels are flexible and lighter, making them suitable for various installations, but their efficiency is typically lower than monocrystalline and polycrystalline panels.
Panels with efficiency ratings above 20% are considered very efficient, ensuring you get the most value for your investment.

Durability
In addition to efficiency, solar panels need to be created with durability in mind. This is incredibly important because solar panels sit on rooftops and are subject to harsh temperature and weather changes. Exposure to the elements causes all solar panels to degrade over time. But the rate of degradation can vary heavily from one solar panel provider to another.
Certifications can be an indication of the quality and durability of a solar panel. Look for certifications from organizations like the Underwriters Laboratories (UL) or Canadian Standard Association (CSA) or oither reputable international certification agencies to ensure the panels meet safety and performance standards.
-
Warranty:
Look for panels with a linear power warranty, which specifies the maximum degradation you can expect over the panel’s lifespan (typically 25 years).
A strong warranty is a key indicator of a solar panel’s quality and longevity.
Other Considerations:
Temperature Coefficient: This indicates how much the panel’s power output changes with temperature.
