Comparison of Solar Power Meter and Intelligence Solar Power Meter and Its Impact on Solar Photovoltaic Design

The terrestrial measurement of solar irradiation power in the selected location is crucial for the solar photovoltaic power plant design. However, it should be carried out manually onsite using the current Solar Power Meter (SPM). A device that can record this value remotely online is needed to ensure more efficient work. Hence, an Intelligent Solar Power Meter (ISPM) using a BH1750 sensor equipped with a cover in the form of an LED light cover was designed. The terrestrial measurement using both devices along with satellite measurement has been carried out in the Merangin site for performance comparison purposes. The result showed that the difference between each device in measuring the probability distribution, the financial model and the intermittent profile is less than 5%, with data that can be monitored remotely using internet connected IoT features.
