ABSTRAK

Atap photovoltaic pv terintegrasi pada bangunan merupakan salah satu cara memperoleh energi listrik. Meskipun di satu sisi energi listrik ini didapatkan secara cuma-cuma di sisi lain radiasi matahari dapat memanaskan interior dan modul pv itu sendiri. Pemanasan interior akan menurunkan kualitas termal sedangkan pemanasan modul pv menurunkan daya listrik yang dihasilkan. Untuk mendapatkan kondisi optimum baik dari segi termal dan pembangkitan energi dalam konteks atap pv terintegrasi peran ventilasi dan insulasi di ruang atap dalam menghambat laju pemanasan modul pv dan interior akan dikaji dan dieksplorasi dalam penelitian ini. Metoda penelitian gabungan eksperimen dan simulasi digunakan untuk memberikan penjelasan teoritis tentang perilaku panas di atap ruang atap dan interior perolehan energi listrik kualitas termal interior serta untuk melakukan optimalisasi. Pada aspek termal eksperimen digunakan untuk merumuskan peran ventilasi insulasi kapasitif dan reflektif. Simulasi dengan perangkat lunak digunakan untuk mendapatkan tipe ventilasi dan insulasi ruang atap terbaik. Simulasi membantu memberikan penjelasan perilaku termalnya. Pada aspek pembangkitan energi eksperimen digunakan untuk mendapatkan karakter modul pv sedangkan simulasi digunakan untuk mendapatkan besarnya insolasi pada bidang miring. Rumah tumbuh yang dikembangkan oleh pemerintah digunakan sebagai obyek eksperimen dalam penelitian ini. Dalam konteks aplikasi atap pv terintegrasi hasil penelitian menunjukkan peran penting aliran konveksi dan radiasi di ruang atap dalam memanaskan interior. Ventilasi dan insulasi tipe Y-terbalik pada ruang atap adalah suatu model insulasi konveksi dan sistem ventilasi yang efektif dalam menghambat laju pemanasan interior dan modul pv. Kombinasi ventilasi dan insulasi tipe Y-terbalik pada ruang atap tipe pelana mampu mendekatkan kinerja termal dan pembangkitan daya listrik dengan kondisi optimal yang diharapkan khususnya untuk aplikasi atap pv terintegrasi di daerah tropis lembab.


ABSTRACT

Roof integrated photovoltaic RIPV in buildings is one of design strategy that allows building to generate its own energy from the sun. Since the sun shines throughout the year in the warm-humid climate of Indonesia radiation is abundant and can be utilized at no cost. However aside from these advantages radiation can easily heat up the photovoltaic pv module and interior of the building which in turns can deteriorate thermal as well as energy performance of the building. To optimize these two performances the study will investigate and further explore role of roof insulation and roof space ventilation in conjunction with the application of RIPV in preventing both the pv module and interior form overheating. In this study experiments and simulations were combined to provide a theoretical explanation concerning thermal behavior in the building especially in roof attic and interior electricity generation and optimization between thermal and energy performance. On the thermal aspect experiments were used to define the role of ventilation capacitive and reflective insulation. Computer simulation is used to investigate the best type of roof space ventilation. Aspects of energy generation were analyzed through experiments especially to obtain the pv module characteristics. In addition simulation is utilized to attain insolation magnitude on an inclined pane. For the research government-developed house design was taken as an object of the experiment. Results of the study showed that in the case of RIPV convection and radiation in the roof space contributed in increasing temperature of interior of the building.Y-inverted insulation type and roof space ventilation was found to be a good combination of roof configuration that was able to lower temperature of the pv module and interior. In warm-humid regions application of RIPV on a gable roof type which were then combined with Y-inverted insulation and ventilation was proved to be able to balance thermal and energy performance closer to the optimum value.
