A 60% cost reduction in solar projects over a span of five years (up to 2021) was matched with a consistent 20% annual growth in its solar capacity.
Decentralized or distributed solar installations have emerged as a definitive trend in the Asia Pacific region. This approach entails the distribution of smaller solar systems across a wider geographic area rather than concentrating capacity in large-scale farms. Australia stands as a testament to this trend's popularity. By the end of 2022, the country witnessed over 3.5 million rooftop solar installations. In percentage terms, that means nearly 21% of Australian households had adopted solar energy, a significant upswing from just 0.2% a decade earlier. Furthermore, Indonesia, with its archipelagic topography, saw over 15,000 villages leveraging decentralized solar systems by 2021, given the logistical challenges of a centralized grid. The trend is not just a reflection of logistical convenience but also an outcome of dropping solar panel prices, which plummeted by 89% between 2010 and 2020, making smaller installations economically viable for individual households and communities.
With the exponential growth of solar power in the Asia Pacific, a significant challenge has materialized: grid integration and stability. The sudden influx of power from solar sources, especially during peak sunlight hours, can create voltage fluctuations and destabilize the grid.
