Investigation effectiveness of agrivoltaic towards solar pv

Investigation effectiveness of agrivoltaic towards solar pv / Abdul Rashid Abdul Kadir
Setiap tahun, dengan peningkatan petumbuhan populasi, permintaan elektrik juga bertambah dari 5% kepada 8% di Malaysia dengan sasaran sebanyak 10GW pada tahun 2020 [1]. Sebagaimana negara-negara lain, Malaysia juga telah mula melaksanakan tenaga boleh diperbaharui sebagai pengganti bagi arang batu. Walaupun tenaga solar boleh dikategorikan sebagai tenaga paling bersih dan sumber tenaga lestari, ruang yang besar diperlukan untuk penggunaannya. Sebaliknya, kerangka kerikil di bawah solar PV boleh menyumbang kepada kesan pulau panas yang akan meningkatkan suhu sekitar di bawahnya [2]. Oleh itu, penggunaan tumbuh-tumbuhan di bawah pelbagai solar dapat membantu mengurangkan suhu udara persekitaran dengan mewujudkan iklim yang lebih sejuk. Kelebihan ini diambil untuk meningkatkan pengeluaran makanan beserta penjanaan tenaga. Dalam kajian ini, pelbagai herba telah ditanam di bawah modul PV. Misai Kucing (Orthosiphon Stamineus), Rerama (Mariposa Christia Vespertilionis), Stevia (Stevia Rebaudiana), telah dipilih sebagai herba-herba eksperimen dalam ladang pertanian solar PV. Matlamat utama untuk kerja ini adalah untuk mengkaji keberkesanan sistem agrivoltaik terhadap PV solar. Hasil kajian menunjukkan terdapat sedikit penurunan suhu sekitar purata PV solar dari 1.29 - 2.04 ºC, suhu panel solar purata menurun sebanyak 0.07 - 2.27 ºC dan kuasa purata meningkat sebanyak 1.35 – 2.9 W. Herba-herba di bawah sistem agrivoltaic menunjukkan kemajuan pertumbuhan yang baik. Kelembapan tanah di bawah kawasan panel solar boleh dikekalkan sebanyak kira-kira 30% lebih tinggi daripada kelembapan tanah di bawah kawasan cahaya matahari langsung. Akhirnya, dengan merujuk kepada hasil dan rujukan, ia disahkan bahawa agrivoltaic dapat mengurangkan suhu ambien yang kemudiannya mempengaruhi kecekapan panel solar. _______________________________________________________________________________________________________ Every year, with the increase of population growth, electricity demand increases 5% to 8% in Malaysia with a target of 10 GW by the year 2020 [1]. Along with the other countries, Malaysia has started to implement renewable energy as an alternative replacing fossil fuel. Although solar energy can be described as the most clean and sustainable energy sources in the world, large space is required for its utilization. On the other hand, gravel underlayment for solar PV site may contribute to a heat island effect which will increase the ambient temperature underneath it [2]. Therefore, the use of vegetation under the solar array could help reduce the ambient air temperatures by creating a cooler microclimate. In this research, various herbs are installed under PV modules. Java Tea (Orthosiphon Stamineus), Butterfly Wing (Mariposa Christia Vespertilionis) and Stevia (Stevia Rebaudiana) are chosen as experimental herbs under solar panel. The main aim for this work is to investigate effectiveness of agrivoltaic system towards solar PV. The result of this research showed there is slightly decrease in average ambient temperature of solar PV from 1.29 - 2.04 ºC, average solar panel temperature is decreased by 0.07 - 2.27 ºC and average output power is increased by 1.35 – 2.9 W. The herbs under agrivoltaic system shows good growth progress. The soil moisture under solar panel area can keep maintained for about 30% higher than the soil moisture under direct sunlight area. In the end, by referring to the results and references, it is verified that agrivoltaic does significantly reduce ambient temperature which later affect the efficiency of solar panel.
