Masjid Darul Naim at Kampung Lintang is highly busy – not with bubur pedas, but with the instalment of solar panels for its solar hybrid system – the result of a collaborative community project by Perundingan KAZ SDN. BHD. and our Faculty of Engineering.
The mosque hosts jemaah mainly from Kampung Lintang and Kampung Bedil Besar. One of the mosque’s appeal is its enthusiasm towards technology and digital connectivity. This Ramadhan, Masjid Darul Naim hosts Madrasah Ramadhan online through Facebook Live. When its solar hybrid system is fully operational, the mosque is expected to save up to 18% of energy.
So, what is the solar hybrid system?
The solar hybrid system, or familiarly known as hybrid solar, is a grid connected solar with energy storage. It has gained popularity in grid-connected residential system due to the attributes of the energy storage system. Using this system, the mosque can save money and resources because the system is designed to prioritise the usage of up to 83kVAh power stored in batteries instead of the grid.
However, great power comes with great responsibilities. High-level expertise is crucial to install the system due to its complexities. Ir. Dr Hazrul Mohamed Basri, our inhouse professional engineer, discussed the load profile analysis and the technical requirement for the design which includes the hybrid solar photovoltaic-grid system, and the one-day battery autonomy designs with Ir. Hj Abang Asri bin Ariffin, the expert from Perunding KAZ Sdn. Bhd. The Masjid Darul Naim’s system is constructed based on the calculations set by the Sustainable Energy Development Authorities Malaysia to optimise energy production and ensure that safety aspects are guaranteed.
The Faculty of Engineering team, consisting of Dr Kasumawati Lias, Associate Prof. Dr Thelaha Masri, technicians Mr. Nasri Eli and Mr. Wan Mohamad Haekal Wan Herdwat, and final year students Mohd Shuffy Suhaidi and Mohd. Zulhilmi Firdaus Rosli, also constructed wiring diagrammes and assisted with the installation of the solar hybrid system to ensure that a precise and specific mounting design is retrofitted.
“Carrying the heavy panels was hard labour.” – Dr Kasumawati Lias.
“Coincidentally, most of the parts arrived in Ramadhan and we just proceed!” Dr Kasumawati, who supervises the installation for the mounting, is delightful that the project, which started before the fasting season, progresses smoothly during Ramadhan.
This hybrid solar project has the capacity of 25kWp, which provides 15kW and delivers 63kVAh of energy for the mosque’s three-phase system. The return on investment is expected for 8 years, whilst the system's lifespan is targeted to be between 10 to 15 years. The Solar Hybrid System is scheduled to be handed over to the Jawatankuasa Masjid Darul Naim early June 2021.
