The effective utilization of solar energy has been urgently required in the fields of agriculture and industry from the view point of energy saving. In order to fulfill this purpose, it would be essential to develop economical and highly reliable pyranometer to measure intensity of solar energy.
Pyranometer of this type using N on P type silicon solar cell used for artificial satellites has been developed.
As a result of three year running test with a thermopile type pyranometer, it was found that this new type has the output of smaller zero drift, quicker response and better stability. In addition to these, error caused by temperature dependence peculiar to semiconductors has been minimized by adopting temperature compensator.
Japan Meteorological Agency has examined this type for one year and admitted the accuracy of within±2.5% error.
