7 Reasons Why You Should Oversize Your PV Array

featured

Oversizing a PV array, also referred to as undersizing a PV inverter, involves installing a PV array with a rated DC power (measured @ Standard Test Conditions) which is larger than an inverter’s rated AC output power (i.e. DC @ STC > AC). It can be a valuable tool for system designers seeking to deliver a maximum amount of energy at a lowest possible specific cost. Reasons for over-sizing PV arrays and important factors to consider are summarized below.

Understanding OptiTrac Global Peak

The technology everyone is talking about right now is power optimizers—electronic components that work directly with the PV module to ensure that the maximum amount of DC power can be extracted from each and every solar panel. This can be particularly advantageous when modules are in heavy shade, as the optimizer companies claim they can “save” as much as 25 percent of the energy lost through shading. However, Joachim Laschinski, technology expert at SMA, explains what the phenomenon of shading actually entails and how SMA has already solved this problem with it’s own OptiTrac Global Peak that’s included with all new Sunny Boy inverters.
