Solar panels generate direct current (DC) power, and computers, printers, telephones, lights, and pretty much every other typical office power load use DC power. Why waste energy converting all that power to alternating current (AC) and back again, just to satisfy a century-old convention for how we electrify buildings? That’s the premise behind a fascinating project underway at China’s Xiamen University that’s using DC power to connect rooftop solar panels to lights, HVAC systems, data centers and plug-in vehicle chargers. Nextek Power Systems is providing the solar-to-building DC power technology, China-based Canadian Solar provides the solar panels, and Palo Alto, Calif.-based startup People Power will provide the cloud-based software platform to connect it to people in the building. Lawrence Berkeley National Laboratory will provide “algorithms for the optimal equipmen...
