Quick Answer
Yes, you may need additional equipment for bifacial solar arrays, such as bifacial compatible inverters, tracking systems, and monitoring software to optimize energy production.
Bifacial Inverter Requirements
To take full advantage of bifacial solar arrays, you’ll need an inverter that is specifically designed for bifacial operation. Look for an inverter with an active backsheet or a bifacial inverter that can handle both mono-facial and bifacial operation. Some popular options include the SMA Sunny Boy 5.0-3-US-22 and the Enphase IQ 7+ with Bifacial capability. Ensure the inverter’s peak power rating matches or exceeds the array’s total power output.
Tracking Systems for Bifacial Arrays
While tracking systems are not strictly necessary for bifacial arrays, they can significantly boost energy production. Bifacial arrays benefit from tracking systems that adjust the angle of the panels to optimize energy capture from both front and back sides. For a 10 kW array, consider a tracked system that can adjust the angle to between 25° and 40° to achieve optimal results. Some popular options include the Sunpower SP Pro and the Array Technologies AP Series.
Monitoring and Optimization Software
To get the most out of your bifacial array, you’ll need monitoring and optimization software that can track energy production from both front and back sides. Look for software that can provide real-time data on energy production, temperature, and other key metrics. Some popular options include the SolarEdge Monitoring Portal and the Enphase Envoy. These systems can help you identify issues, optimize performance, and ensure your array is running at its best.
