SOLAR PANEL DATABASE
“We are the first generation to feel the impact of climate change
and the last generation that can do something about it.”
— Barack Obama
A FIRST-OF-ITS-KIND COMPREHENSIVE DATABASE
At Spectrum Energy, we've developed the first-of-its-kind comprehensive solar panel database, designed to feature the critical aspects that matter most when choosing a solar panel. This database includes key performance metrics like power output, efficiency, and long-term durability. To make the decision-making process even easier, we've created a proprietary scoring system to grade each panel based on these metrics. Our goal is simple: to educate and empower homeowners and business owners who are interested in going solar, ensuring they make informed choices that best suit their energy needs and long-term sustainability goals.
We hope you enjoy using our database, and we invite you to contact us to design a solar system tailored specifically to your needs.
KEY TERMS
Power Output (Watts): The amount of electrical power a solar panel can produce under Standard Test Conditions (STC), which simulate ideal conditions: 1,000 watts of sunlight per square meter, a cell temperature of 77°F (25°C), and an air mass of 1.5. Power output is measured in watts (W).
Efficiency % (STC): The percentage of sunlight a solar panel converts into usable electricity under Standard Test Conditions (STC). These conditions include 1,000 watts of sunlight per square meter, a cell temperature of 77°F (25°C), and an air mass of 1.5. A higher efficiency means more energy is generated from the same amount of sunlight in ideal conditions.
Watts/ft²: The amount of power a solar panel produces per square foot. This measures the power density of the panel.
Power Tolerance: The range of possible deviation from the stated power output. For example, a panel rated at 450W with a power tolerance of ±3% could produce between 464W and 436W.
Year 1 Power Loss: The percentage of power loss that typically occurs in the first year of a solar panel’s operation due to initial degradation.
Degradation Rate (% per year): The annual reduction in a solar panel's power output after the first year, expressed as a percentage. Lower degradation rates are better for long-term performance.
Power Output in Year 25: The estimated power output after 25 years of operation, considering the degradation rate. It shows how much power the panel is expected to produce in the future.
Temperature Coefficient of Pmax (% per degree Celsius): The percentage decrease in power output for every degree Celsius the panel's temperature rises above 77°F (25°C). Lower values indicate better performance in hot conditions.
Test Load Front (Snow): The maximum weight of snow that the front of the panel can withstand without damage.
Test Load Back (Wind): The maximum wind pressure that the back of the panel can tolerate without structural failure.
