Sistem fotovoltan (PV) dipasang secara meluas untuk meningkatkan penggunaan tenaga boleh diperbaharui serta mengurangkan kesan buruk terhadap alam sekitar yang berasaskan bahan api fosil. Sistem rakaman fotovoltan dianggap sebagai aspek penting untuk mengetahui kecekapan sistem panel solar PV. Bagaimanapun, masih tiada rakaman atau peranti pengawasan untuk memastikan sistem PV berterusan berfungsi. Oleh itu, projek ini memberi tumpuan kepada pembinaan sistem rakaman parameter untuk mengatasi masalah ini. Dengan menggunakan sistem rakaman, pengguna boleh memantau keluaran solar panel fotovoltan mereka (voltan dan arus) dalam masa nyata, melalui kaedah Internet of Thing (IoT). Nilai yang dirakam daripada penderia boleh disimpan dan dikemas kini secara berterusan dalam talian. Sistem terdiri daripada sensor untuk mengukur dua nilai voltan, arus dan suhu. Mikropengawal NodeMCU dipilih sebagai platform open source IoT yang mempunyai perisian tegar yang menggunakan WIFI ESP8266. Data dihantar ke laman web Adafruit IO melalui sambungan WIFI. Secara keseluruhan, hasilnya menunjukkan bahawa sensor yang dibangunkan untuk data PV yang direkodkan berfungsi dengan betul. Data yang diproses oleh mikrokontroler NodeMCU dipaparkan di papan pemuka halaman web perkhidmatan awan Adafruit IO. Papan pemuka menunjukkan voltan dan output semasa dari panel solar, output voltan dari bateri boleh dicas semula dan suhu persekitaran di sekitar panel solar PV. Dari sistem rakaman photovoltaic, kecekapan sistem yang dibangunkan dan faktor lain yang menyumbang atau membawa kepada kerosakan dalam sistem solar boleh direkodkan.

Photovoltaic (PV) system is widely installed to increase the share of renewable energy as well as to reduce the environmental impact fossil fuel-based energy. Photovoltaic recording system is considered as a crucial aspect to observe the efficiency of the PV solar panels system. However, there has been no recording or monitoring device to ensure continuous working of the PV system. Hence, this project focuses on developing parameter recording system to overcome the problem. Using the recording system, users are allowed to monitor their photovoltaic solar panels output (voltage and current) in real time, through Internet of Thing (IoT) method. The recorded values from the developed sensors can be continuously stored and updated in the cloud service. The system consists of sensors each for measuring two voltages values, current and temperature. NodeMCU microcontroller is chosen as the open source IoT platform which includes firmware which runs on the ESP8266 WIFI Development Board. The data are sent to Adafruit IO webpage through WIFI connection. Overall, the result show that the developed sensors for PV data recorded are working correctly. Data processed by the microcontroller NodeMCU were displayed on the dashboard of Adafruit IO cloud service webpage. The dashboard shows the voltage and current output from the solar panel, voltage output from rechargeable battery and the environment temperature around PV solar panel. From the photovoltaic recording system, the efficiency of the developed system and the other factor that contributed or leading to malfunction in the solar system can be recorded.
