摘要

The rapid exhausting traditional energy sources and the contemporary constantly intensifying energy entreaty with respects to biological matters have reinforced concentrated research on solar energy novelty. Capturing maximum energy from the sun by applying photovoltaic solar technology is challenging. A limited feature that affect the solar energy harvest of such technology include the photovoltaic material, topographical area of solar irradiances, surrounding temperature and climate, the angle of sun and orientation of the panel. This work presents an automated and low-cost irradiance-temperature (W/m2) logging meter, Low-Cost Sensor (Pyranometer) to measure Solar Irradiance in Nsukka, Nigeria. The core distinctive of this device is the low-cost of all its mechanisms. The design of this device is grounded on by means of temperature sensor DHT11 and phototransistor PT202C. This design was implemented for the periods of 90 days along with standard pyranometer and thermometer installed to two 250 watts photovoltaic (PV) solar panel similar at University of Nigeria, Nsukka. This device enhanced sensitiveness to solar irradiance, permitting a brilliant feedback of the device in a range from approximately 250 to 1200 x10-9 m. This device incapacitates out dated complications in this kind of device and propositions comparable features to those of thermopile-based irradiance meter and, hence, can be used at all setting up where consistent sizing of solar isolation is required and the overall result indicates that the coefficient of correlation of the solar isolation gotten with the projected device is 0.9996.
