Longfei Wood Products Factory Achieves Milestone with PV Power Plant

In a significant development for renewable energy, the photovoltaic (PV) power plant at the Longfei Wood Products Factory in Yichun, Heilongjiang Province, China, has recently achieved full grid connection. This milestone marks the official start of operations for the first HPBC 2.0 distributed PV power plant.

Yichun, renowned as "The Forest Capital of China," is characterized by its vast forestry resources, boasting an 84.8% forest coverage rate across a forestry area of 40,000 square kilometers. This region is pivotal for the timber industry, housing numerous power-intensive operations. The Longfei Wood Products Factory, integral to this industry, relies on heavy machinery, including sawmills and cutting machines, which creates a considerable demand for electricity.

With an installed capacity of 2.2 MW, the new power plant employs LONGi's advanced HPBC 2.0 dual-glass PV modules, each capable of generating 630W. Remarkably, this facility is expected to produce around 3.2 million kWh annually, which will not only meet the electricity requirements of the factory but also generate annual electricity sales revenue of approximately 1.2 million RMB.

The HPBC 2.0 modules stand out due to their exceptional performance, generating an additional 110,000 kWh of energy compared to equivalent TOPCon PV installations, reflecting a remarkable 3.56% improvement in energy output. Furthermore, LONGi’s dual-glass technology enhances capacity and efficiency by achieving a 5% increase in energy generation relative to other modules.

Optimizing Installation for Enhanced Efficiency

Achieving optimal energy output is a priority in PV installations, and the Longfei project adopts an innovative ground-mounted system with a carefully calculated tilt angle. This design decision enhances solar radiation absorption, resulting in a whopping 25% boost in power generation over traditional rooftop configurations and simplifies maintenance efforts for operators.

Furthermore, in November 2022, LONGi introduced its groundbreaking HPBC 1.0 cell technology, paving the way for the BC technology era. The transition to HPBC 2.0 represents an evolution of this technology, overcoming earlier challenges and achieving industry-leading cell efficiencies exceeding 26.6%. This technology is built using LONGi's proprietary high-quality TaiRay silicon wafers, minimizing degradation and enhancing the overall reliability and longevity of the power generation system.

One of the standout features of HPBC 2.0 is its superior performance even under extreme temperatures. In Yichun, where winter can plunge to -30°C, the modules exhibit remarkable resilience, featuring an improved temperature coefficient of -0.26%/°C, which is better than earlier technologies. This reliability under demanding conditions underlines the suitability of HPBC technology for diverse climates across China.

A Step Towards Sustainable Development

The commissioning of the HPBC 2.0 PV power plant is a significant stride toward transforming Yichun’s economy from a conventional timber industry base to a more sustainable, ecological model. It showcases the potential for distributed PV systems to thrive across the country, endorsing LONGi's commitment to advancing the BC technology ecosystem. As this technology gains traction, LONGi aims to collaborate with various partners to deliver high-performance PV power plants tailored for both commercial and industrial applications. These initiatives promise not only increased energy efficiency but also contribute to a greener and more sustainable future.

With continuous advancements in solar technology, LONGi and its collaborators are well-positioned to champion the cause of renewable energy and support the global transition towards sustainable development. As this innovative power generation approach takes hold, it sets the stage for broader adoption of solar energy solutions that can power industries and economies for decades to come.
