Rooftop solar for export textile factories: lower costs, greener supply chains
Du Long Industrial Park is welcoming many export-oriented textile and dyeing projects. For these companies, rooftop solar is not only about saving money but also part of the push for greener supply chains.
Why textile factories should care
- Brands require emission cuts: many major fashion brands have set emission reduction targets across their supply chains and ask factories to report energy use and the share of clean power.
- High daytime consumption: knitting, dyeing and finishing lines run multiple shifts – matching the hours when solar generation is strongest.
- Large factory roofs: wide, flat roof areas are well suited for installation.
- Abundant sunshine: the Thuan Bac area enjoys many sunny hours, ideal for solar power.
Key benefits
- Lower power bills: self-consumed solar power reduces the energy bought from the grid, especially during daytime normal and peak hours.
- Cooler roofs: panels shade the roof and help reduce the temperature inside the factory.
- Helps companies meet ESG criteria and reduce emissions: clean-energy output data can be included in reports to brands.
Three ways to go solar – even without capital
| Self-investment | Roof lease | ESCO partnership | |
|---|---|---|---|
| Company capital | 100% of system cost | Zero | Zero |
| Main benefit | All solar output | Regular roof rental income | Solar power cheaper than grid power |
| Operation & maintenance | The company | Du Long Power | Du Long Power |
| Best for | Companies with available capital | Factory owners wanting extra income | Plants with high daytime consumption |
Under the ESCO partnership, Du Long Power invests in the entire system; the company only pays for the solar power it actually uses, at a price lower than grid power. During the contract term, the company may take over (buy) the system if needed, as agreed.

What to prepare
- Roof information: area, roof type, roof age, structural drawings (if available).
- Recent electricity bills to estimate daytime consumption.
- Production and expansion plans for the coming years.
For factories under construction, consider solar when designing the roof so the structure is suitable and no reinforcement is needed later.
