Weather patterns can be notoriously difficult to predict, yet doing so is an essential part of getting the most out of solar systems. Carsten M. Steenberg, Vice President of Product Management at RainWise, briefs us on the benefits of having a dedicated weather station for a forecast that can be relied on.
PES: Thanks for speaking to me Carsten. Firstly, how important is it to monitor and measure the efficiency of photovoltaic systems throughout their lifecycle?
Carsten M. Steenberg: The expected life cycle is around 25 years or more using the latest technology. After that, photovoltaic (PV) module efficiency degrades at about 0.5% per year, and of course, failure rates tend to be higher as the equipment ages.
