Taiwan Union Technology Corporation (TUC) (Stock Code: 6274), headquartered in Zhubei City, Hsinchu County, has recently completed the grid connection of its photovoltaic power plant. In proactive alignment with the government's green energy obligations for major electricity users, TUC reached out to Billion Watts for project development and selected the SolarEdge smart inverter solution. The company has begun selling power to Taiwan Power Company, generating stable revenue, with an estimated initial annual return on investment exceeding 10%. In line with company policy, TUC plans to eventually transition to self-generated green electricity to support manufacturing needs, secure renewable energy certificates, and fulfill its renewable energy goals.

Taiwan Union Technology Corporation (TUC), since 1998, has successfully expanded into the production of copper-clad laminates and bonding sheets, continuously delivering top-quality foundational materials that support the global electronics industry with high added value and environmental sustainability. In alignment with its commitment to corporate social responsibility and ESG investment strategies, TUC is dedicated to achieving sustainable development through renewable energy and green technology. As companies worldwide work toward carbon reduction and net-zero emissions, along with new international carbon tax policies, TUC has chosen to advance its green energy planning efforts.

Elaine Chen, Associate Director of Billion Watts, expressed her honor in serving TUC, a leading player in Taiwan’s electronics industry. She highlighted Billion Watts’ substantial achievements, including over 200 MW of photovoltaic projects connected to the grid across Taiwan and a proven record in operation and maintenance services. Billion Watts offers the industry’s only 20-year warranty, alongside a smart solar power solution that ensures photovoltaic safety and reliability.

The Phase 1 canopy-type rooftop solar power plant, with a grid-connected capacity of 395.2 kW, is equipped with three SolarEdge SE120K inverters, 504 SolarEdge P801 optimizers, and a monitoring system to manage the plant. Recently, it successfully completed grid interconnection with Taiwan Power Company (Taipower). However, the real challenges for the solar system only begin after grid connection. Beyond the module’s inherent 0.5% annual degradation rate, each solar panel has a unique degradation rate. When using traditional centralized inverters, any issues like bird droppings, dust, shading, or a single module’s decline can impact the entire plant’s power generation. In this regard, the DC power optimizers provided by SolarEdge enhance the output of each module, effectively reducing power losses caused by module mismatch.

Additionally, with a higher risk of flammable materials stored at the site, SolarEdge’s equipment complies with the international UL1699B standard, helping mitigate fire risks caused by electric arcs and reducing the risk of electric shock to personnel. Its built-in SafeDC™ mechanism lowers DC voltage to a safe level when the AC is disconnected, ensuring the safety of maintenance and firefighting personnel.

Billion Watts provides project design, execution, and pre-sales planning, including design optimization, system simulation comparison, return-on-investment analysis, engineering services, training, and remote operation. In addition, with a professional maintenance team, the company offers accurate site alerts, performance monitoring, remote troubleshooting, and other services, delivering diverse solutions that exceed customer expectations.
