Partnering itself with Solinvest, CE has successfully installed a 35 kWp, grid-tied PV system on the rooftop of a government office building (Gedung Dinas Otonom Pemda Kota Jayapura) in Entrop, Jayapura. This PV system – without the use of battery storage – is distinctive for Eastern Indonesia considering that this is the first grid-connected system in the region.
It features 186 solar panels in total; a combination of mono-crystalline and thin-film modules, as well as several different types of inverters. Approximately 50 MWh/year of energy production is expected to power many appliances in the building, including lights, computers and air-conditioning units.
This particular project serves research and educational purposes of three universities, namely Bandung Institute of Technology (ITB), University of Twente (The Netherlands), and Universitas Cendrawasih, as well as an NGO (WWF Indonesia). The different types of panels and inverters will output various data which allows the universities to compare the performance of different PV technologies operating in tropical conditions.
For this purpose, a weather station and electrical sensors have been installed to constantly measure all aspects of the PV system. The strategic location of this public building will also promote the use of PV panels to the local community.
Grid-connected PV system itself guarantees constant, reliable power; ensuring that the office will always have access to electricity. In the case of bad weather when solar energy fails or is insufficient, electricity shortages will be imported from the local PLN grid.
The implementation of PV will in overall reduce the building’s electricity bills.
