Recently, Pearl Electric's green PV energy storage transformer project has been successfully grid‑connected and has commenced generating its first “green electricity”. This self‑owned rooftop solar‑plus‑storage facility marks an important milestone for Pearl Electric, demonstrating our comprehensive capability to deliver a complete green PV energy storage transformer project from design to grid connection.
The project fully utilizes the company’s nearly 23,000‑square‑meter rooftop space and existing power supply infrastructure, with an installed capacity of 1.814 MWp and an energy storage system rated at 200 kW/458 kWh. Through rigorous on‑site surveys and scientific planning, it operates under a “self‑consumption with surplus feed‑in” model. Under this mode, on‑site generated green power first supplies factory production loads, and excess electricity is fed back to the public grid, realizing high-efficiency utilization of renewable energy. The supporting power transformers deployed in this system guarantee stable voltage conversion, which is the core foundation of the whole green PV energy storage transformer project.

Photovoltaic (PV) power generation is a technology that directly converts solar energy into electricity through the photovoltaic effect at semiconductor interfaces. In contrast to conventional fossil fuel‑based power systems, PV generation offers zero emissions, pollution‑free operation, and renewable characteristics. With geographical flexibility enabling deployment on building rooftops and other surfaces, it represents an energy‑efficient and eco‑friendly electricity production method.
Combined with matching energy storage devices and dedicated transformers, rooftop PV projects can smooth power output fluctuations, stabilize on‑site power quality, and further improve the self‑consumption rate of solar power. Such distributed renewable solutions are widely adopted in modern industrial parks, which aligns with Pearl Electric’s product portfolio for solar‑oriented compact substations and power transformers built for the green PV energy storage transformer project.
The project is designed to generate approximately 40.4 million kWh of electricity over its 25‑year operational lifespan. With an initial annual output of 1.73 million kWh from the photovoltaic plant and an average yearly generation of 1.62 million kWh, it is projected to save around 273 metric tons of standard coal equivalent (SCE) and reduce carbon dioxide emissions by 729.9 metric tons annually.
Besides cutting carbon footprint, the project also brings tangible economic returns by lowering the factory’s purchase of grid‑supplied commercial electricity. It achieves synergistic economic and environmental benefits, setting a practical example for manufacturing enterprises to carry out on‑site green power transformation, and verifying the reliability of our transformer solution inside the green PV energy storage transformer project.
Moving forward, Pearl Electric will deepen its focus on carbon footprint management across the entire lifecycle — from origin, conversion, utilization to disposal — while implementing digital transformation and process reengineering in manufacturing operations. These strategic initiatives aim to optimize energy and resource efficiency, progressively advancing toward the construction of smart industrial parks and zero‑carbon factories.
While pushing forward internal energy‑saving renovation, Pearl Electric also continues to deliver reliable transformers and compact substation products for global photovoltaic and energy‑storage clients. The successful operation of this in‑plant green PV energy storage transformer project serves as a live reference for overseas customers who need customized power equipment for their solar plus storage plants. The company strives to contribute both internally and externally to the global energy transition and sustainable industrial development.
