Patent ID: 7754963

Claim:
A solar power generation system comprising at least a solar cell and a cooling mechanism, the cooling mechanism comprising: a cooling means for cooling the solar cell; a memory means for memorizing an optimum cooling and driving state of the cooling means with respect to an output of the solar cell, the memory means including a microcomputer having a nonvolatile memory; and an operation means for operating the optimum cooling and driving state of the cooling means with respect to the output of the solar cell, wherein the memory means comprises a plurality of previously determined standard temperature values for an atmosphere where the solar cell is installed, each of the plurality of standard temperature values corresponding to a respective one of a plurality of predetermined time points of the year, wherein the operation means comprises a clocking function and operates the cooling means in accordance with a selected one of the plurality of standard temperature values from the memory means for a current time point at the installation location of the solar cell, wherein the cooling mechanism further comprises a power detection means for detecting an output power of the solar cell, and wherein the operation means estimates a magnitude of a rise in the temperature of the solar cell based on the detected output power of the solar cell and based on the selected one of the plurality of standard temperature values.
