Summary: | Photovoltaic system is one common alternative in reducing usage of fossil fuel to
generate electricity. Photovoltaic system requires low cost of maintenance and is less
location-dependent. However, the cost to install a photovoltaic system is relatively high.
Furthermore, not all locations are suitable to build a photovoltaic system. Therefore,
solar irradiance data is crucial in determining feasibility to install a photovoltaic system.
In practical, solar irradiance data is collected using data logger and cannot be collected
remotely. To tackle these problems, a cost saving irradiance data collection system
which is able to perform solar tracking mechanism and IoT data collection, is designed
and constructed. Arduino UNO was implemented as the core in performing solar
tracking mechanism, while ESP32 was implemented as the core in performing IoT data
collection system. In this project, LDRs were calibrated in order to achieve high
precision in tracking the Sun. High precision current-to-voltage circuity for both
pyrheliometer and pyranometer were constructed in order to achieve accurate current
reading in ESP32, which will indirectly help in achieving high precision pyrheliometer
and pyranometer. Low cost pyrheliometer and pyranometer were designed and
constructed in this project. Extra features were included in this project. One of the
features includes the initialization of solar tracker when the solar tracker is powered on.
Another extra feature included was the ability of Blynk user interface platform in
displaying the current status of solar tracker besides being able to display real-time solar
irradiance data.
