LEARN | The Importance of Solar System Design pt 2

In our NEW series, we unpack the importance of solar system design, and what it involves. In part one, we looked at Mechanical Design, outlining the key design attributes, and their relationships with performance modelling calculations. In part two, we give you a basic understanding of the electrical portion of solar system design… Understanding Electrical Design The electrical design of the array determines the electrical behaviour of the array: the powers and voltages that the system will be running at. This can have a major impact on the system's energy production. 1. String Size and V...

LEARN | The Importance of Solar System Design pt 1

Did you know that the efficiency (energy yield) of a solar system is largely affected by the design of the system? The component choice will drive the behaviour of the module(s) and inverter(s). The orientation of the modules will drive the sun angles at each hour of the year, and therefore the total energy yield of the array. And the electrical design (module stringing, conductor sizes, etc.) will determine the system voltages, which impact wire losses and inverter efficiency. In our NEW series, we unpack the importance of ...
