What Makes for the Best Solar Panels?

Efficiency: Efficiency refers to how well a solar panel can convert sunlight into electricity. Higher efficiency means more energy generation from a smaller area. High-quality panels typically have efficiencies above 20%, producing more electricity per square foot of panel area.

Materials and Technology: The type of materials used and the technology employed play a significant role. For instance, monocrystalline silicon panels, known for their single, continuous crystal structure, are generally more efficient and durable than polycrystalline silicon panels. Advanced technologies like PERC (Passivated Emitter and Rear Cell) and bifacial designs also enhance performance.

Durability and Longevity: A high-quality solar panel has been built to withstand various environmental conditions for years. This includes resistance to UV exposure, high winds, heavy snow loads, and temperature fluctuations. The lifespan of a good quality panel is typically 25-30 years or more.

Temperature Coefficient: Refers to the panel’s ability to perform under hot conditions. All solar panels lose some efficiency when they get hot, but high-quality panels have a lower temperature coefficient, meaning their performance declines less in high temperatures.

Warranty and Manufacturer Support: Reputable manufacturers stand behind their products with solid warranties. A high-quality solar panel usually comes with a performance warranty of 25 years or more and a product warranty covering defects for at least 10-12 years.

PID Resistance: Potential Induced Degradation (PID) can cause significant power loss over time. High-quality panels are designed to be PID-resistant, ensuring stable performance throughout their lifespan.

Certifications and Testing Standards: Look for panels that meet international testing and quality standards. Certifications from organizations like the International Electrotechnical Commission (IEC) and Underwriters Laboratories (UL) indicate that the panels have been rigorously tested for quality and safety.

Build Quality: This includes aspects like framing, backing, and encapsulation. Good build quality ensures the panels are robust, can support heavy loads, and are sealed against moisture and other environmental factors.

Energy Payback Time: This is the time it takes for a solar panel to generate the amount of energy used to produce it. High-quality panels have a shorter energy payback time, making them more environmentally friendly.

Aesthetics: While not a direct measure of performance, the appearance of panels is essential for residential customers. High-quality panels often come with sleek designs, like all-black panels, that blend well with the roof.
