While color solar panels are an excellent option for putting your home on the map, they do have a few disadvantages:Color is not ideal if you live in an area with heavy snow or rain because it can be reflected off of the surface and decrease efficiency levels by up to 15%. Keep this in mind when choosing colors like white or blue.Color panels are not as efficient as black or dark blue. . [pdf]
Nominal power (or peak power) is the of (PV) devices, such as , and . It is determined by measuring the and in a , while varying the under precisely defined conditions. The nominal power is important for designing an installation in order to correctly dimension its and . Nominal power is also called peak power because the test conditions at which it is determined a. Peak Power in Solar Panels is defined by the metric KILOWATT PEAK: kWp. kWp represents the theoretical peak output of the system, used as a measure to compare one system against another. [pdf]
