Abstract
A solar power generation system having a solar cell provided therein and which is provided with a cooling mechanism, characterized in that the cooling mechanism has a cooling system for cooling the solar cell and a memory and operation for memorizing or operating an optimum cooling and driving state of the cooling system with respect to an output of the solar cell, wherein the cooling system is driven based on an output of the memory and operation system.
Claims5
A method for controlling a solar cell in a solar power generation system, comprising the steps of:
- (a) detecting an electric energy output of said solar cell,
- (b) computing a magnitude of a rise in the temperature of said solar cell based on said detected output of said solar cell,
- (c) adding said computed temperature rise magnitude to a prescribed estimate temperature of said solar cell to presume a temperature of said solar cell at a current time,
- (d) computing a temperature difference between said presumed temperature and a temperature range within which the temperature of said solar cell is intended to be controlled,
- (e) computing a forcible cooling drive magnitude for lowering said temperature difference by a cooling means for cooling said solar cell, and
- (f) driving said cooling means so as to meet said computed forcible cooling drive magnitude by means of a control means.
