The darker the panel, the lower the production. . What Color is the Wire Although the International Electrotechnical Commission (IEC 62930) and the US UL 4,703 standards allow the use of different colored cables to distinguish polarity, in actual large-scale ground power station projects over 500 MW, you will find that more than 95% of modules are. . But are solar panels actually three different colors? No. The color attributions reference the backsheet that sits behind the cells, which are all generally the same color (a very dark blue). For example, here is a snapshot of an Enphase energy system from the Enlighten Manager (enlighten. com) where you have (3) branch circuits, one on a south roof, another on an east. . How to distinguish positive and negative poles of photovo gative terminals of the panel are located at either end of this series. Most panels will. .
