In a groundbreaking study, researchers have unveiled the economic viability of hybrid off-grid solar power plant systems for households in Yogyakarta, Indonesia. This research, led by Hendra Setiawan from the Electrical Engineering Department at Universitas Islam Indonesia, provides crucial insights into the potential benefits of solar energy in a region where electricity access is often inconsistent.
The study meticulously analyzed a solar power system comprising eight polycrystalline photovoltaic panels, each with a capacity of 410Wp, a 3kW inverter, and a 48V 300Ah lithium ferrophosphate battery. Operating since early 2021, the system recorded energy outputs ranging from 3.2kWh to 17.4kWh, ultimately yielding an impressive total annual energy of 3,740.7 kWh after accounting for an 85% efficiency rate. This translates to an annual average yield of 1,140.5 kWh per kilowatt peak (kWp) and a performance ratio of 63.4%.
Setiawan emphasized the significance of these findings, stating, “The results of our analysis indicate that investing in hybrid off-grid solar systems can be highly beneficial under specific conditions. This is particularly important for households in regions with limited access to the grid.” The study also highlighted the Net Present Value (NPV) as a critical indicator of investment feasibility, projecting a payback period of 24 years with a 7% discount rate and accounting for the degradation of photovoltaic systems and battery performance over time.
The implications of this research extend beyond individual households. As Indonesia grapples with energy security and sustainability challenges, the findings advocate for governmental support and regulatory frameworks to enhance solar power applications. Setiawan noted, “Government intervention is essential to create a conducive environment for solar energy investments, which can ultimately lead to a more sustainable energy future for Indonesia.”
This study, published in ‘Jurnal Elkomika’ (which translates to ‘Journal of Electronics and Computer Science’), underscores a pivotal moment for the energy sector in Indonesia. By demonstrating the commercial viability of solar energy systems, it paves the way for increased adoption and investment in renewable technologies, potentially transforming the energy landscape in the region.
As the world increasingly turns to sustainable energy solutions, research like this not only informs policy decisions but also inspires innovations that could reshape energy consumption patterns, making solar power a cornerstone of Indonesia’s energy strategy.
