Highest yields – even in sweltering heat.

In all photovoltaic modules, output diminishes as temperatures rise, which results in yield losses. This is why the performance of conventional technologies is considerably lower in the summer months or in hot regions, in spite of high irradiation values.

The characteristics described in the module datasheet refer to the performance under standard testing conditions, which are measured at a module temperature of 25 °C. Any additional degree Celsius gained by the module under real conditions means a loss in output. 

Temperature has less effect on Solar Frontier’s CIS modules than on crystalline silicon modules, which means Solar Fontier’s PowerModules have a higher temperature stability. This is reflected in a lower temperature coefficient of the output, which is usually indicated on the datasheet as a percentage per degree Kelvin.

The advantage of greater temperature stability becomes even more evident when you consider that installations are at work particularly during high summer or in warmer regions. Modules that are exposed to an ambient  temperature of 30 °C can reach surface temperatures as high as 70 °C. Given this possibility, the temperature stability of CIS PowerModules is a great advantage, which can be reflected in energy production as much as 10% higher than crystalline modules.
