Design low-intensity concentrator system for silicon photovoltaic / Norhafizah Nordin
Penumpu memainkan peranan penting dalam meningkatkan tenaga keluaran oleh peranti fotovoltaik tanpa meningkatkan kos secara ketara. Didalam projek ini, sistem penumpu penyinaran rendah telah direka dan dibina untuk digunakan dengan peranti fotovoltaik silikon. Pembinaan penumpu adalah berdasarkan pada cermin rata yang memantulkan dan menumpukan cahaya matahari yang diterima keatas permukaan peranti fotovoltaic. Ini akan meningkatkan bilangan foton yang diterima oleh panel solar bergantung kepada bilangan cermin yang digunakan. Untuk menganalisis prestasi penumpu, pengesan-pengesan untuk mengukur ciri penting panel dan sistem simpanan data telah dibangunkan menggunakan Arduino. Prestasi penumpu dianalisis berdasarkan tiga keadaan. Terdapat dua jenis ujian yang telah dijalankan dalam projek ini iaitu ujian panel solar dan ujian sistem. Ujian panel solar ini bertujuan untuk melihat ciri-ciri I-V panel solar untuk setiap keadaan. Ujian sistem dijalankan untuk mendapatkan kuasa keluaran panel solar dan beberapa parameter prestasi telah dikumpulkan menggunakan sistem simpanan data selama empat jam sehari untuk setiap keadaan. Berdasarkan keputusan yang diperolehi, prestasi reka bentuk dua penumpu adalah yang terbaik. Walau bagaimanapun, prestasi penumpu juga dipengaruhi oleh suhu. Suhu panel untuk panel solar dengan dua penumpu mempunyai nilai yang lebih besar daripada panel solar dengan satu dan tanpa penumpu. Didapati terdapat sedikit penurunan kepada prestasi dua penumpu kerana mencapai suhu tertentu. Walau bagaimanapun, kesan suhu boleh dikurangkan dengan mengekstrak tenaga haba kepada sumber berharga seperti air panas, sekali gus meningkatkan lagi kecekapan keseluruhan sistem. _______________________________________________________________________________________________________ Concentrator plays an important role in increasing the energy output of Photovoltaics device without significantly increasing the cost. In this project, low irradiation concentrator system has been designed and develop to be used with silicon photovoltaic device. The concentrator developed, was based on the flat mirror that reflects and focus incoming sunlight onto the surface of the photovoltaic devices. This increase the number of photons received by the solar panel depending on the number of mirrors used. To analyze the performance, sensors measuring important panel characteristic and data logger system was develop using Arduino. The performance of concentrator is being analyzed based on three conditions. There are two types of test that has been conducted in this project which are solar panel testing and system testing. Solar panel testing is conducted to observe the I-V characteristics of solar panel for each condition. System testing is conducted to obtain the output power of solar panel and a number of performance parameters have been collected using data logger system over 4 hours per a day for each condition. Based on the result obtained, the best performance of concentrator design is the one that uses two concentrators. However, the performance of concentrator also is influenced by temperature. The panel temperature of a solar panel with two concentrators has much greater value than solar panel with one and without concentrator. Slightly drop in performance of concentrators was noticed due to reaches a certain temperature. However the effect of temperature can be reduced by extracting the heat energy to valuable source such as hot water, thus further increasing the overall efficiency of the system.
