Hybrid RF and Solar PV energy harvester

Hybrid RF and Solar PV energy harvester / Erva Natasha Mohd Saiful
Penuaian tenaga telah wujud untuk masa yang sangat lama. Pada masa itu, tenaga telah dituai pada awal revolusi elektrik dengan meletakkan penjana di sungai yang telah dikuasakan oleh air yang mengalir untuk menjana tenaga elektrik. Tenaga yang paling kerap digunakan adalah tenaga matahari yang merupakan item yang paling penting dalam menghasilkan tenaga. Konsep pengeluaran tenaga dari alam semula jadi, yang boleh digunakan untuk menggantikan sumber kuasa konvensional. Penuai tenaga perlu ditukar ke voltan untuk kuasa sistem. Salah satu cara untuk menggunakan penuaian tenaga dengan menggunakan sumber-sumber hibrid. Sumber hibrid boleh dibentuk dengan menggunakan tiga jenis sumber iaitu Termoelektrik Generator (TEG) yang varians suhu sekitar dan haba. Kedua, sumber getaran yang digunakan seperti motor dan peranti getaran, Frekuensi Radio (RF) yang menghasilkan kuasa pancaran. Selain daripada itu, penuaian tenaga adalah pelaksanaan dunia sebenar pertama berskala bateri tanpa wayar platform pengesan untuk kualiti hidup dan Internet Perkara permohonan (IOT). Tenaga yang biasa digunakan ialah teknologi tenaga matahari. Walau bagaimanapun, peranti kini perlu menggunakan elektrik secara berterusan tetapi tenaga matahari mempunyai had. Ini kebimbangan tesis mengenai siasatan terhadap tenaga penuaian untuk tenaga RF dengan menggunakan panel solar. Kedua-dua tenaga RF dan tenaga solar boleh diserap melalui panel solar. Dalam kata lain, panel solar juga bertindak sebagai antena untuk menerima isyarat dan menukar kepada tenaga RF. Analisis akan dibuat untuk menganalisis sama ada tenaga RF boleh didapati dari panel solar. Antena patch telah direka dan dibina. Panel solar telah diuji dengan peralatan RF untuk mengukur parameter prestasi panel solar dan dibandingkan dengan patch antena. Untuk kekuatan isyarat, panel solar menunjukkan prestasi yang baik berbanding dengan antena patch dimana panel solar adalah -32.67dBm di 2.5GHz manakala patch antena adalah -38.88dB di 2GHz. Sebaliknya, tenaga ambien menunjukkan sedikit perbezaan dari segi penerimaan kuasa tetapi untuk frekuensi, kekerapan yang diterima adalah dalam julat ± 1.8GHz. Selain itu, gandaan untuk panel solar adalah 2.31dB dan ia adalah lebih rendah daripada gandaan patch antena 4.73dB kerana toleransi dalam proses pembuatan PCB. Kesimpulannya, frekuensi dominan untuk panel solar adalah 1.8GHz ± dimana kegunaan untuk frekuensi ini digunakan di dalam GSM. _______________________________________________________________________________________________________ Energy harvesting has been around for a very long time. At that time, energy was harvested in the early days of the electrical revolution by putting generators on river mills that were powered by running water to generate electricity. The most common energy is solar energy which is most important item in energy harvesting. The concept of energy extraction from nature, which can be used to replace the conventional power source. The energy harvester needs to be convert to voltage or current to power the system. One of the ways to use energy harvesting by using the hybrid sources. Hybrid sources can be formed by using three types of sources which are Thermoelectric Generator(TEG) that the variance of temperature between the surrounding and the heat. Secondly, the vibration sources that are used the vibration sources such as motor and the shaking device, the Radio Frequency(RF) that are produced radiated power. Other than that, energy harvesting is the first real-world implementation of scalable battery-less stand-alone wireless sensor platforms for quality of life and the Internet of Things (IoT) application. The energy that commonly used are solar energy technologies. However, the devices currently need to use electricity frequently but solar energy have it limitations. This thesis concerns on the investigation on harvesting energy for RF energy by using the solar panel. Both energy which are RF energy and solar energy can get from the solar panel. In the other words, the solar panel also act as the antenna for receiving the signal and convert to RF energy. The analysis will be made to analyze whether the RF energy can be got from solar panel. The patch antenna was designed and fabricated. The solar panel was tested with RF equipment to measure the solar panel performance parameters and compared with patch antenna. For the signal strength solar panel showed a good performance compared to patch antenna which for solar panel was -32.67dBm at 2.5GHz while patch antenna was -38.88dB at 2GHz. On the other hand, the ambient energy showed slightly difference in terms of receiving power but for the frequency, the frequency received was in range ±1.8GHz. Moreover, the gain for solar panel was 2.31dB and it was lower than patch antenna gains of 4.73dB due to the tolerance in PCB manufacturing process. In conclusion, the dominant frequency for solar panel is ±1.8GHz which the application for this frequency is in GSM
