ABSTRACT:
A low power consumption solar cell meter-recorder capable of measuring the output power of a solar cell and recordingthe measured data and the date of measurement, all at a remote location using only battery power, is disclosed. The voltage output of the solar cell is converted into a frequency which is counted over a predetermined time to produce the measured data. The measured data is stored in a first address section of a memory. Digital date information is generated and stored in a second address section of the memory. Both the first and the second address sections are addressed by the same address number. When a read out is desired, the measured data and date stored in the memory are displayed.
