Understanding the quantity and quality of solar energy that can be harnessed at a site is essential for estimating and optimizing the cost of energy production for most developing and developed nations. This article details the design of an efficient, low-cost system to measure solar irradiance using dual-axis tracking, irradiation sensors, and an algorithm to track the solar position. The sensed data is acquired using a data acquisition system and provides a user-friendly remote access using a collaborative platform to monitor and control real-time data with options to change parameters and graphically display the data and live streaming. Evaluating a potential site for solar energy installation could be studied without acquiring expensive equipment. Positive results from the study conducted to capture the perceived usefulness, overall adaptability and ease in understanding of underlying scientific concepts and their retention for novice users indicate the effectiveness of the system developed.
