Evaluating CertainTeed Solar: A Comparative Analysis


“Solar panel efficiency” signifies the adeptness with which a solar panel captures sunlight and transmutes it into usable electricity. Under identical conditions, a high-efficiency solar panel will generate more electricity than a lower-efficiency panel of equivalent size. Thus, a superior efficiency rating is generally more desirable.

The performance of CertainTeed panels and solar shingles depends on the specific model chosen for your system. CertainTeed offers products with efficiency ratings ranging from 17.2% to 20.21%. Their Solstice panels, with efficiency ranging from 19.9% to 20.5%, meet industry standards. Panels achieving 18% or higher are considered “high efficiency.” For comparison, SunPower panels, available on the EnergySage Marketplace, achieve an impressive 22.8% efficiency. CertainTeed’s solar shingles and tiles typically range from 14% to 18% efficiency, falling within the standard range for solar roofing solutions.

Performance: Temperature Coefficient 

Understanding Temperature Coefficient

The temperature coefficient serves as a critical metric, reflecting the operational efficiency of your solar panels under suboptimal thermal conditions. Solar panels, akin to other electronic devices, exhibit peak performance when maintained at a cooler temperature, ideally around 25°C (77°F). The temperature coefficient quantifies the extent to which a panel’s efficiency is influenced by temperature variations, particularly during scorching, sunlit summer days.

Impact of Temperature on Solar Panel Efficiency

For every degree above the optimal 25°C (77°F), the electrical output of your solar panel diminishes according to its temperature coefficient. To illustrate, the temperature coefficient for CertainTeed Solstice panels, encompassing both the 400W and 440W variants, stands at 0.35%/°C. Consequently, a one-degree rise in the panel’s temperature from 25°C (77°F) results in a 0.35% decrease in electrical production. Should the temperature elevate to 35°C (95°F), the reduction in electricity generation would be 3.5%.

Optimal Temperature Coefficient for Solar Panels 

Given the likelihood of experiencing numerous hot, sun-drenched days annually, it is imperative for your solar panels to possess the lowest feasible temperature coefficient. CertainTeed’s array of solar products boasts temperature coefficients ranging between -0.35% and -0.45%, ensuring minimal efficiency loss under elevated temperatures.


When investing in significant assets like a television, automobile, or solar panels, a strong warranty from the manufacturer is essential. This assurance indicates the company’s confidence in the durability and quality of their product. In the context of solar panels, the materials warranty, also known as the product or equipment warranty, ensures that the manufacturer will replace any panel that fails due to manufacturing defects or environmental issues.

Comprehensive Coverage by CertainTeed 

CertainTeed provides an extensive 25-year warranty on all its solar products. This warranty encompasses panels, inverters, racking equipment, and the roof’s asphalt shingles. Notably, the inverter warranty is detailed: 25 years for microinverters, 25 years for optimizers, 12 years for optimized inverters, and 10 years for string inverters. This extensive coverage highlights the company’s commitment to long-term reliability.

Assured Power Output 

The power output warranty is a testament to CertainTeed’s confidence in their panels’ performance. It guarantees that the solar panels will produce at least 85% of their original output after 25 years. This assurance is critical for long-term energy planning and cost savings.

Specifics of Degradation and Coverage 

As with most warranties, CertainTeed’s product warranty covers the natural degradation of panel quality due to normal wear and tear from roof installation. However, it does not cover damage from extreme weather events or maintenance by uncertified workers. The annual degradation rate of CertainTeed’s solar products must not exceed 0.54%, ensuring minimal performance loss over time.

Unique Workmanship Warranty 

CertainTeed provides more than just a standard product warranty. They offer a special workmanship warranty, usually covered by the solar installer. Opting for a “Silver” installer ensures a 15-year workmanship guarantee, while choosing a “Gold” installer extends this assurance to 25 years. This gives you considerable confidence in the quality of your installation.
