Bifacial Modules - enphase IQ8MC Installation And Operation Manual

IQ8MC/IQ8AC/IQ8HC Microinverters Installation and Operation Manual
The output voltage and current of the PV module depend on the quantity, size, and temperature of the PV cells, as
well as the insolation of each cell. The highest PV module output voltage occurs when the temperature of the cells
is the lowest, and the PV module is at an open circuit (not operating).

Bifacial modules

Enphase IQ8 Series Microinverters are compatible with bifacial PV modules if the temperature-adjusted electrical
parameters (maximum power, voltage, and current) of the modules, considering the electrical parameters,
including the bifacial gain, are within the allowable microinverter input parameters range. In evaluating the amount
of bifacial gain, follow the recommendations of the module manufacturers.
Bifacial solar modules produce power from both sides of a bifacial module, increasing total energy generation. The
power gained from the rear side (bifacial gain) is highly influenced by various design factors such as albedo,
module elevation, pitch, temperature, and shading. The bifacial gain can be anywhere between 0% to 30% of the
nominal rating (front-side power rating) of the module. Because the bifacial gain is highly influenced by various
design considerations, pairing the bifacial module with the right microinverter depends on the electrical
characteristics of a given module.
