Dian Solar and Huawei Team Up to Build Smart Solar Power Systems in Indonesia
Published · 3 min read
PT Dian Swastatika Sentosa Tbk (DSSA), through its Dian Solar brand, has partnered with Huawei Digital Power to develop an integrated smart solar power plant system in Indonesia. The collaboration covers smart photovoltaic (PV) technology and a battery energy storage system (BESS) ecosystem.
The partnership brings together Dian Solar’s local market presence with Huawei’s FusionSolar technology platform, a system designed to monitor, optimize, and manage solar power generation in real time.
What the Technology Does
At the center of the collaboration is a Solar Innovation Hub powered by FusionSolar. The platform provides real-time performance monitoring of solar installations, tracking power output, voltage, temperature, and system efficiency through centralized dashboards.
Smart PV optimizers are a key part of the system. These tools manage individual solar panel performance independently, preventing a single underperforming panel from reducing output across an entire array. This is especially important in conditions involving shading, dust, or panel aging.
The platform also supports predictive maintenance, using data analytics to identify potential failures before they happen. Research shows this approach can cut maintenance costs by up to 30 percent and reduce system downtime by as much as 70 percent.
Battery Storage Is Central to the Plan
The partnership also focuses on building a battery energy storage ecosystem alongside solar generation. Huawei’s BESS products, including the LUNA2000 Series, integrate directly with solar systems through hybrid inverters that manage energy flow between panels, batteries, and the grid.
Storage allows solar energy generated during peak daytime hours to be discharged during evening peak demand periods, when solar output has already dropped. This makes solar-plus-storage a more reliable and economically valuable energy source for grid operators and industrial customers.
Huawei’s LUNA2000-215 Series, launched in early 2025, uses a hybrid air and liquid cooling system, an approach designed to manage battery heat more effectively across different climate conditions, including tropical environments like Indonesia.
Why This Matters for Indonesia
Indonesia is working to add 42.6 gigawatts of renewable energy capacity by 2034 under its latest Electricity Supply Business Plan, known as RUPTL. The broader national goal targets 75 gigawatts of operating renewable capacity by 2040.
To meet that target, the country needs to install roughly 5 gigawatts per year, a significant jump from its historical pace. Solar has added only 717 megawatts over the past decade despite favorable conditions.
Currently, renewables make up just 19 percent of Indonesia’s electricity mix, with solar contributing only 0.2 percent. The Dian Solar-Huawei partnership directly addresses the technology and supply chain gaps slowing that expansion.
Local Manufacturing Adds to the Push
Dian Solar is also part of a joint venture that opened Indonesia’s first integrated solar manufacturing plant in June 2025. The facility, PT Trina Mas Agra Indonesia, is located in the Kendal Industrial Estate in Central Java and has an annual production capacity of 1 gigawatt.
The plant uses i-TOPCon Advanced technology, producing panels with efficiency rates of up to 23.2 percent and output of up to 720 watts-peak per module. Total investment in the facility exceeded 1.5 trillion Indonesian rupiah, or approximately $91.4 million USD.
That domestic manufacturing base reduces Indonesia’s dependence on imported solar components, a constraint that has historically slowed deployment.
Who Benefits
Industrial customers across the Indonesian archipelago are the primary market for the smart solar system. The country’s archipelago geography also makes distributed solar-plus-storage systems well suited to remote islands currently dependent on expensive diesel generation.
Indonesia’s electricity demand is projected to grow between 4.8 and 5.2 percent annually, with peak demand potentially reaching 77.3 gigawatts by 2030. Faster deployment of intelligent, integrated solar systems is increasingly seen as critical to meeting that growth with clean energy.
