To provide interested homeowners with some basic information on how to plan a solar PV system to generate electric power in residence. . Solar photovoltaic system is one of renewable energy system which uses PV modules to convert sunlight into electricity that can be either used directly or stored (i.e. in batteries). . Location: Top of building facing sky with minimal shading from tall buildings or trees Angle: Lying the panel flat (0°) produces maximum energy in Brunei, slightly tilting angle ( less than 5°) would be preferable to allow rain water to run off properly. Roof area: Depends on how large the system is. Orientation:Panel installed facing south to be m. . The size of your system depends on your power consumption of loads that need to be supply and available roof space. (i) Calculation of power consumption A. Find out from the electric bill to know your total electricity use in kilowatt-hours per day. Alternatively, add the kilowatt-hours needed for all appliances together to get the total kilowatt-h.

At the moment, there is no regulatory governing the installation of solar panel in Brunei. Companies follow international standards for solar PV systems that convert solar energy into electrical energy, as well as for all the elements in the entire system.
Major active solar installations in Brunei include the country’s first, Tenaga Suria Brunei, launched in 2010 with a capacity of 1.2 MWp, and Brunei Shell Petroleum’s 3.3 MWp solar plant, launched in 2021 to supply power to its headquarters. Both plants have plans for further expansion.
Cabling and trenching works can be very costly due to the installation and maintenance process. Hence, for landscaping and outdoor lightings, solar is the cheaper and more convenient option. How can I maximize solar energy production in Brunei?
Many of you might not know this, but we do have our own solar farm right here in Brunei and it’s been in operation since 2010. This B$20 million solar farm is named ‘Tenaga Suria Brunei (TSB)’ and is located in Seria. With a nominal capacity of 1.2 kWp, the farm covers an area of about 12,000 sq meters with exactly 9,234 pieces of solar panels!
For a 10 kW solar power system and capacity factor of 13% (for Brunei), such system can produce approximately 227,760 kWh of energy over their lifespan (10 x 13% x 24h x 365 days x 20 years). As Brunei uses block electric tariff, electricity tariff of BN$0.06 per kWh will be used in calculation.
The Sultanate also targets achieving at least 200 MWp of solar energy capacity by 2025. This project also supports the Brunei Climate Change Secretariat’s strategies to increase renewable energy adoption and reduce carbon emissions.

In 2004, the Renewable Energy Development Act (REDA) was passed into law. It provides tax exemptions for companies dedicated to producing renewable energy on the island. An amendment to REDA was promulgated in 2008 and it created a program for tax exemptions as well as incentives for continuing work on development of solar power and other renewable energies. There is a stark contrast in energy production between non-renewable and renewable. [pdf]
