PROBLEM TO BE SOLVED: To provide a low-cost solar power generation system eliminating a complicated and expensive circuit and a battery with a large capacity, and efficiently using the power generated through the system.SOLUTION: The solar power generation system adjusts loads of electric appliances on a solar panel, which is voltage-controlled. The system achieves a simpler circuit (with less connections of active elements), eliminating or reducing the use of a battery, by changing loads of electric appliances in response to the maximum output of the solar panel. Accordingly, all or most of power for operating a refrigerator, a freezer, and other electric appliances can rely on the solar power generation system using no battery. In the same way, the solar power source can be used for kitchen garden implements. Preferably, the source is used in hours of sunshine, which enables the system to operate at a low cost and without using a battery. |
