Design of solar insolation power logging system with ADC error testing and correction

摘要

This study presents a low cost solar insolation meter with accurate measurement of inherent non-linear transfer characteristics of ADC. Measured values were found close to accuracy of highly sophisticated instruments (pyranometer and pyrheliom-eter), which are costlier for large-scale use, low commercial availability and need for a specialized knowledge for handling. Test results over a long duration under varying seasonal conditions were almost identical to those of a calibrated standard pyranometer.
