JOMBANG — PT Investasi Hijau Selaras (HIJAU), together with PT Pei Hai International Wiratama Indonesia, has officially inaugurated the installation of a Phase I rooftop Solar Power Plant (PLTS) with a capacity of 1.515 kWp and simultaneously signed a cooperation agreement for the development of Phase II with a capacity of 2.262 kWp. This project marks another concrete step by both companies in supporting the clean energy transition within the manufacturing industry sector.
President Director of PT Investasi Hijau Selaras, Victor Samuel, explained that in Phase I, the rooftop solar PV system has been installed and is now operational to support the electricity needs of PT Pei Hai’s factory. Meanwhile, Phase II will significantly increase capacity to enhance the contribution of renewable energy to the company’s operations.
“In Phase I, we installed a 1.515 kWp solar PV system, which will be followed by Phase II with a capacity of 2.262 kWp. The system is designed to be reliable and long-lasting,” said Victor.
During the installation process, HIJAU implemented industrial-grade technology and safety standards, including the use of corrosion-resistant hot-dip galvanized (HDG) structures, high-quality materials, and real-time performance monitoring systems. These measures were taken to ensure optimal long-term system performance.
Victor acknowledged that the implementation of Phase I faced several challenges, particularly high rainfall intensity and delays in the delivery of solar modules from overseas. However, these obstacles were successfully addressed through work schedule adjustments and intensive coordination with logistics partners.
Entering Phase II, HIJAU will focus its strategy on optimizing system capacity and sustainability. Planning is based on actual electricity load analysis using a power quality analyzer, roof condition inspections, and building structure assessments. In addition, HIJAU has prepared a structured operation and maintenance program to maintain system reliability.
From an environmental perspective, the implementation of Phase I is estimated to reduce carbon emissions by up to 30,865 tons of CO₂, equivalent to planting approximately 49,384 trees over a 15-year period.
Meanwhile, PT Pei Hai International Wiratama Indonesia emphasized that the utilization of solar PV is part of the company’s commitment to sustainability principles. HRD Manager of PT Pei Hai International Wiratama Indonesia, Moelyono, stated that the use of solar energy aligns with global standards, particularly for export-oriented companies.
“The use of solar PV helps us reduce carbon emissions while also improving long-term operational cost efficiency,” said Moelyono.
He added that the selection of HIJAU as a partner was based on its track record and comprehensive solutions, ranging from technology and flexible business models to after-sales services. The achievements of Phase I were considered to have exceeded expectations by successfully reducing electricity costs while lowering the company’s carbon footprint.
In Phase II, PT Pei Hai will prioritize capacity expansion and the integration of smarter energy monitoring systems to further optimize the use of solar energy. This collaboration is expected to serve as a model for other manufacturing industries in supporting the national Net Zero Emission target set by the government for 2060.
“We hope this synergy can become a role model for clean energy transition in Indonesia while enhancing the competitiveness of national industries in the global market,” Moelyono concluded.
