How to measure the reflectivity of photovoltaic panels
develop a new guideline to properly measure reflectance in the solar field of concentrating solar thermal plants. This topic has already been addressed by researchers by several approaches [12][13], and is the main focus of the new.

JIS R3106 stipulates methods for measuring and calculating visible transmittance, visible reflectance, solar transmittance, solar reflectance, and normal emittance as indices for expressing the properties of flat glass.
The goal of this document is to serve as a guidance on the relevant parameters and measurement possibilities to reliably evaluate the reflectance quality of a solar reflector material. It is a tool on how to obtain and provide the necessary data on reflectance properties, so that the material in question can be adequately evaluated for its.
We define clear sky air mass one global horizontal (“AM1GH”) solar reflectance Rg,0, a simple and easily measured property that more accurately predicts solar heat gain. Rg,0 predicts the annual peak solar heat gain of a roof or pavement to within 2 W m −2, and overestimates N by no more than 3%.
One of the most common measurements made by the solar energy industry today is quantification of a material’s surface reflectance. These materials are as diverse as metal coatings, semiconductor coatings, anti-reflective coatings on window material, as well as the window material itself. While both transmission and reflectance are of interest .
