    Shedding light on renewable energy tech

    Izah Azahari

    Representatives from companies shared their project experiences and opportunities with Roof Top Solar PV as the ‘Roof Top Solar Photo-Voltaic (PV)’ became one of the main focusses during the afternoon session of the Renewable Energy Policy and Development Forum in conjunction with the Brunei Mid-Year Conference and Exhibition (MYCE) 2021 as part of the Energy Theme Week recently.

    Sivli Sdn Bhd Project Engineer Muniem Syakir bin Haji Md Iskandar Zulkarnain said Sivli is an electrical engineering company that specialises in the electrical transmission and distribution network, working closely with the Department of Electrical Services (DES).

    Since 2018, the project engineer said the company began exploring the solar market and has since carried out several projects with the government such as solar street lighting, off-grid systems and grid-connected solar PV systems.

    In 2018 and 2019, Sivli carried out several off-grid projects with the capacity of three kilowatts and five kilowatts in remote locations in Belait District, where lead-acid batteries were sized to supply power for each site, while their solar lights project saw a total of 85 units of 100W LED solar lights installed along Jalan Labu in Temburong District where they repurposed existing light poles.

    The project engineer also touched on the net-metering pilot project in Temburong District, which is aligned with the Temburong District Development Authority (AKDT) initiative for a sustainable development of Temburong District.

    “All these solar installations were done by the roadside to generate public interest when they pass by, and we want to capitalise on the roof tops as that is the most accessible space for solar panels and available to most people in their homes.”

    Muniem Syakir, in his presentation, detailed the steps to owning a roof top PV plant with net metering which includes a site survey to determine the appropriate size of system and potential challenges; structural integrity assessment to be done by a registered civil and structural engineer, and to be submitted to the Authority for Building Control and Construction Industry (ABCi) for acknowledgement; net metering application to be submitted to the Sustainable Energy Department for approval and requires Electrical Qualified Person (QP) approval for proposed system design; installation of system after successful application; and commissioning of system after net-metering assessment by QP approval.

    He also shared the unique challenges the company faced within the different projects, material planning and accessibility, as well as on aspects of opportunities for solar PV systems, where new buildings should be designed to facilitate future rooftop installations, and PV contractors could work together during the design phase, lowering the cost for installation in the future and giving the option to consumers. As technology matures and expertise increases, costs will also be lowered, along with the development of renewable energy policies to stimulate the growth of solar power.

    Meanwhile, Perusahaan Wadura Business Development Manager Wong Ching Ming detailed on the net-metering solution: what net-metering is; the types of metering schemes for PV such as the gross metering and bi-directional metering (which enables net-metering); the net-metering scheme; and the types of metres used along with the metre data sample retrieved.
