The SunSource® Commercial Energy System is a whole-building solution that uses solar energy to power a solar-ready Energence® premium rooftop unit (RTU). According to the manufacturer, Energence units can achieve an effective efficiency of 34 SEER and beyond when the SunSource system is integrated with the RTU. The solar modules are connected directly to the RTU, so electricity generated from the modules can power the RTU and other equipment or appliances in the building. Up to 25 solar modules can be hooked up to each RTU. The modular design of the commercial energy system allows additional solar modules to be installed at any time, and no system redesign is required. With the SunSource system, if one solar module fails, or does not perform to its maximum capacity, output from the rest of the solar modules is not affected, said the company. Each solar module uses a microinverter to convert dc power harnessed by the panels to ac power, which is then sent to the RTU. The communications module allows online monitoring of system status, energy production, and environmental benefits in real time. The system will automatically monitor and analyze the solar performance 24/7 and is viewable on a secure website.
