Understanding the result
What does the temperature coefficient mean?
Operating temperature affects how efficiently photovoltaic modules convert sunlight into electricity. The power temperature coefficient describes the relative change in module output for every 1°C increase above the Standard Test Conditions (STC) reference temperature of 25°C.
A negative coefficient means output decreases as module temperature rises. A value closer to zero therefore represents less temperature-related power loss under comparable conditions. The original announcement compares M72(HC) with a typical value cited for similar modules.
Laboratory results
Testing conducted at KIWA Laboratory
Philadelphia Solar tested the temperature coefficient of its 166 mm-cell M72(HC) module at KIWA Laboratory, referencing the IEC 61215 standards identified in the company announcement.
Performance comparison
M72(HC) versus the cited reference value
According to the announcement, M72(HC) achieved a power temperature coefficient of −0.295%/°C versus a cited comparison value of −0.35%/°C for similar modules. Under comparable measurement conditions, the reported result represents a smaller relative power decrease as temperature rises.
