In recent years, using renewable energy, especially solar energy, has become popular. The tropical monsoon climate, high radiation intensity in Vietnam brings great potential for exploiting solar power.

While the national power system is under increasing pressure, especially during the dry season and peak heat waves, the solution of distributing power sources from rooftop solar power models is considered the "key" to share the burden with the traditional power grid and promote the development of green energy.

In Bac Giang province, with the rapid industrial development and the continuously increasing demand for electricity, rooftop solar power has affirmed its role in ensuring local energy security. Some businesses in Bac Giang are becoming models in applying rooftop solar power to both optimize costs and affirm their commitment to sustainable development.

BGG Lang Giang Garment Joint Stock Company has pioneered the installation of rooftop solar power systems with an installed capacity of 1,615.68 kWp since 2020. Since then, the company has not only significantly reduced electricity costs in production operations but also generated hundreds of millions of VND in surplus electricity from the grid.

Crystal Martin (Vietnam) Limited Company in Van Trung Industrial Park has deployed a 2,675 kWp capacity system, with technical documents standardized according to Decree 58/2025/ND-CP.

The company not only ensures safe operation but also affirms its ability to comply with ESG (Environment - Social - Governance) standards in the global production chain.

Along with the business sector, many households have boldly invested in solar power systems with BESS – Battery Energy Storage System. This is a smart trend, helping to optimize electricity usage, ensuring safety even when the grid loses power.

Vu Van Trung's household in Viet Yen Township installed a 49.68 kWp system with a BESS capacity of 51.2 kWh to help maintain stable household electricity even when the grid is interrupted. At the same time, the rooftop solar power system also helps prevent heat for the building.

The family of Nguyen Cong Toan in Bac Giang city also effectively exploits the 18 kWp system with BESS 16.1 kWh to help save electricity costs, optimize efficiency and reduce dependence on grid electricity.

As of May 2025, 602 customers in the province used rooftop solar power with a total capacity of nearly 15 MWp, the cumulative electricity output to the grid in the first 5 months of the year hit more than 2.6 million kWh with a pre-tax amount of more than 5 billion VND.

Bac Giang Power Company has synchronously deployed technical support solutions, guidance on connection procedures and monitored safety along with widespread communication to spread awareness about the benefits of rooftop solar power.

The self-produced and self-consumed rooftop solar power model is not only a solution to save electricity but also an important part in promoting green development of the province. Each rooftop and factory with solar power has contributed to building a Bac Giang that develops sustainably and is self-sufficient in energy.

Bac Giang implements incentive mechanisms for rooftop solar power development

BAC GIANG - On the morning of November 14, the Bac Giang Provincial People's Committee held a conference to disseminate Decree No. 135/2024/ND-CP dated October 22, 2024 of the Government (Decree 135) stipulating mechanisms and policies to encourage the development of self-produced and self-consumed rooftop solar power.
