In the heart of Southeast Asia, a small nation is making significant strides towards a sustainable energy future. Brunei, known for its vast oil and gas reserves, is now turning its gaze towards the sun, exploring the potential of residential rooftop solar power. A recent study published in the EPJ Web of Conferences, which is the English translation of the European Physical Journal Web of Conferences, has shed light on the immense possibilities that lie above the rooftops of Brunei’s homes.
Brunei has set ambitious targets for electricity generation, aiming for approximately 600 MW by 2035 and about 1,200 MW by 2050. However, with limited land resources and a significant portion of the land dedicated to agriculture and forest preservation, the country is looking for alternative means of energy generation. This is where residential rooftop photovoltaic (PV) systems come into play.
The study, led by Muhamad Nor Asiah from the Department of Electrical and Electronics Engineering at the Faculty of Engineering, Universiti Teknologi Brunei, focuses on the residential sector, which primarily consists of detached, semi-detached, and terrace houses. These types of homes, which make up about 86% of households in Brunei, typically have spacious rooftops suitable for installing PV panels.
The research utilized building plans from the National Housing Scheme (RPN) in Brunei to estimate the average residential rooftop area available for solar panel installations. The findings are promising. The total residential rooftop area in Brunei is estimated to be between 4,219,902 square meters and 8,051,467 square meters. This vast expanse of rooftop real estate has the potential to generate between 787 GWh and 1,501 GWh of electricity annually. This energy production represents about 19% to 36% of the current national electricity generation, a significant contribution that could help Brunei meet its future energy needs.
“Investing in residential rooftop PV systems could be highly beneficial for the country regarding solar electricity generation,” said Muhamad Nor Asiah. “This study provides a solid foundation for policymakers and investors to consider the potential of rooftop solar in Brunei.”
The commercial impacts of this research are substantial. For the energy sector, this presents a new frontier for investment and development. Solar panel manufacturers, installation companies, and energy providers all stand to benefit from the growth of residential rooftop solar power. Moreover, this shift towards renewable energy could lead to job creation and economic growth, further diversifying Brunei’s economy.
The study also highlights the importance of strategic planning and policy-making in harnessing the full potential of rooftop solar power. It calls for a collaborative effort between the government, private sector, and local communities to overcome technical, financial, and regulatory challenges.
As Brunei moves forward with its renewable energy goals, this research serves as a beacon, guiding the way towards a sustainable and energy-secure future. The findings not only underscore the viability of residential rooftop solar power but also pave the way for similar studies in other countries with comparable challenges and opportunities.
The implications of this research extend beyond Brunei. It offers a blueprint for other nations looking to maximize their solar potential while preserving valuable land resources. As the world continues to grapple with climate change and energy security, innovative solutions like residential rooftop solar power will play a crucial role in shaping a sustainable future.
The study, published in the EPJ Web of Conferences, is a testament to the power of research in driving meaningful change. It is a call to action for policymakers, investors, and communities to embrace the potential of rooftop solar power and work together towards a brighter, more sustainable future.
