ABSTRACT:
A device and method are disclosed for measuring solar energy during a testing period which uses a cell to provide an electrical signal in response to received solar energy and a resistor connected to the cell for providing an adjusted electrical signal at a valve chosen to represent a specified value of solar energy. A pulse train is provided which has a reduced frequency proportional to the adjusted electrical signal, the number of pulses are counted and this accumulated number is displayed, the number being representative of the solar energy received by the cell during the testing period. Batteries are used to supply power to the device and a normally open switch activates the display which is normally inactive during the testing period to conserve the life of the battery.
