Abstract: A solar power system for supplying electrical energy to a load based on solar energy comprising at least one solar panel, a power supply, and at least one mode select switch. The at least one solar panel comprises at least one solar cell. The at least one mode select switch is operatively connected to the at least one solar panel, the power supply, and the load. The at least one mode select switch is operable in a first mode and in a second mode. In the first mode, the at least one solar cell is capable of supplying electrical energy to the load. In the second mode, the power supply supplies electrical energy to the at least one solar cell such that the at least one solar cell generates heat.

Abstract: A system for generating electrical power signals from a fluid fuel source. The system comprises an engine and a generator. The engine burns the fuel and is connected to the generator such that the generator generates a raw power signal. An output stage generates an output power signal from the raw power signal. A control circuit controls the operation of the engine based on the output power signal. The control circuit further controls the operation of the engine based on an output current of the generator when this output current exceeds a current threshold level. The control circuit additionally controls the operation of the engine based on a temperature of the engine when the engine temperature exceeds a rated temperature level. The system thus generates sufficient power to supply a variable load but stays within an operating range defined by a rated power level and the rated temperature level.
