Understanding Solar Panel Specifications
When choosing solar panels, it's important to understand the key specifications.
Power Output (Watts)
The wattage rating tells you the maximum power output under ideal conditions. Higher wattage means more electricity generation.
Efficiency
Efficiency is the percentage of sunlight converted to electricity. Higher efficiency panels produce more power in less space.
Temperature Coefficient
This shows how performance changes with temperature. A lower coefficient means better performance in hot weather.
Warranty
Look for panels with at least 25 years performance warranty. This guarantees a minimum power output over time.
