4 Frequently Asked Questions about "Photovoltaic panel reflectivity standard specification"

What standards are available for the energy rating of PV modules?

Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.

How is solar reflectance quantified?

In solar applications, reflectance is best quantified in terms of solar-weighted reflectance, since not all parts of the solar spectrum have equal amounts of energy. So weighting a reflector's spectral reflectance according to the energy content of the solar spectrum is proper.

Is there a guideline for solar weighted reflectance and monochromatic specular reflectance?

In spring of 2011, a first interim guideline version on a specified measurement method to obtain solar weighted reflectance and monochromatic specular reflectance values with commercially available instrumentation was created by this small working group and published at the SolarPACES homepage .

How is solar-weighted reflectance calculated?

Solar-weighted reflectance Solar weighting of the reflectance parameters is calculated with the currently valid standard solar spectrum ASTM G173 for direct irradiance and the appropriate Air Mass (i.e. for Europe and USA it is AM 1.5). Solar weighting is performed according to the equations provided in chapter 7 and Annex B .
