We don’t wholesale to alternative businesses.
Temp COEF, short for Temperature Coefficient, is the percentage at which the performance of a solar panel reduces beyond the Standard Test Condition (STC) temperature point (e.g. 25oC).
As cell temperature increases, the power output by the solar panel decreases by a nominated percentage.
Relevance to Western Australia: A lower Temp COEF value assists in a calculable improved energy yield (kWh), especially in peak summer.
It’s easy to be confused when researching solar. Most solar panels in 2025 are comprised of a 3.2mm glass composite (glass-laminate or dual-glass), the weight of a solar panel more often than not represents the efficiency of the technology inside.
- Less efficient panels weigh more (Watt for Watt) through increased surface area.
Cut through the spin if Watts, Temp COEF and module efficiencies become too much. On a more simplified scale, try using weight of a solar module for quick comparison.
Ideal average leading brand technology 2025 residential rooftop module weight: 22 kG. Quick guide:
475W (22 kG) is efficiency superior to 440W (22 kG).
475W (24.6 kg) is efficiency inferior to 440W (22 kG).
