Abstract: A self-regulated solar power delivery system for data center. The ambient temperature outside of the data center is monitored. When the temperature exceeds a preset threshold, a controller activates switches to connect a PV system to a DC/DC converter and the DC/DC converter to a plurality of thermoelectric coolers (TECs). When the temperature drops below a second threshold, the controller disconnects the PV system. In this manner, when additional cooling is needed the most, i.e., during hot ambient temperature, the PV system also generates the most energy and can be used to energize TECs which enhance heat transportation from the processors. The PV system may also be used to activate a liquid cooling pump or other cooling devices to enhance heat removal from the servers.
