Project Overview

Highjoule is converting the rooftop of its Shanghai headquarters into a clean energy asset, aligning corporate strategy with national green goals. The newly commissioned 302.5kWp distributed solar system maximizes the use of the available roof area of the commercial building. By utilizing a “self-generated, self-used” model with surplus power supplied to the grid, the project not only reduces the company’s daily electricity costs, but also enhances its energy self-sufficiency and contributes positively to the environment.

The project’s grid connection underscores Highjoule’s commitment to clean energy. It also serves as a practical model for deploying distributed PV in commercial settings.

Project Highlights and Technical Solution

Installed Capacity: The project has a total installed capacity of 302.5kWp, with an estimated annual power generation of hundreds of thousands of kWh, sufficient to meet the majority of the factory’s daytime electricity needs. Especially during peak production periods, solar power generation plays a vital role in balancing power demand and alleviating grid pressure.

Module Selection: To ensure long-term, stable system operation, the project selected monocrystalline silicon PV modules with stable performance and high conversion efficiency. These modules have a low degradation rate and can continuously provide stable power over a long lifecycle, improving the overall return on investment.

Intelligent Operation and Maintenance: The project is equipped with an intelligent data monitoring platform, which provides real-time monitoring of power generation data, power plant operating status, and emission reduction results. Through remote operation and maintenance and refined management, the system operates efficiently and safely, quickly locating and resolving faults, and ensuring efficient power generation from the solar system.

Operational Mode: The project’s electricity is primarily used for the plant’s own consumption, with any excess energy fed into the public grid via grid connection. This operating model not only ensures the plant’s green power needs but also generates additional economic benefits by feeding surplus power into the grid.

Economic and Environmental Benefits

Energy Savings and Consumption Reduction: By generating its own electricity and using it for its own consumption, Highjoule reduces its reliance on the external power grid. The system now meets approximately 60% of the building’s daytime electricity demand, leading to a substantial reduction in energy costs and a favorable payback period.

Green Emission Reduction: The project is expected to save hundreds of tons of standard coal annually, significantly reducing emissions of carbon dioxide and other harmful gases. This reduction tangibly lowers the company’s carbon footprint, representing a concrete step towards corporate climate leadership.

Asset Revitalization: A previously underutilized factory rooftop has been transformed into a green electricity production base. This initiative improves the efficiency of rooftop resources and generates sustained economic benefits for the company, achieving asset appreciation and green transformation.

Industry Demonstration and Social Impact

Highjoule’s 302.5kWp distributed solar rooftop project demonstrates the practical application and potential of distributed PV power generation in the commercial sector, providing a successful case study for other companies. The project demonstrates that photovoltaic power generation is not only technically feasible but also economically viable, with broad application value.

With growing awareness of environmental protection and green energy, similar projects will be implemented in more companies and industrial parks in the future, promoting the optimization of the global energy structure and the achievement of sustainable development goals.

Looking Forward

Building on this project’s success, Highjoule is evaluating further integrations of solar and storage technologies across its operations. In the future, we will further expand distributed PV and other renewable energy solutions, and strive to provide customers and society with greener, more efficient and intelligent energy services, and promote the low-carbon transformation process.
