Solar Irradiance Meter using Practical I-V Curve Construction Method

The increasing household installation of photovoltaic generation system is creating a strong demand for equipment that enables accurate measurement and evaluation of the electric output of solar module (array). In order to fabricate such equipment, it is necessary to develop an inexpensive and highly accurate solar irradiance meter as well as excellent evaluation and diagnostic software.I constructed a solar irradience meter on the basis of the above requirements by applying the widely accepted principle of the Practical I-V Curve Construction Method which I developed.The results of my study indicate that a simple, general purpose and highly accurate solar irradiance meter can be developed.
