Overview

Khanh Hoa has some of the best solar irradiation in Vietnam, ideal for rooftop solar. For factories with heavy daytime loads, solar significantly reduces the energy purchased from the grid.

More and more international brands require suppliers to demonstrate renewable energy use and emission reductions. A rooftop solar system is a practical way to meet these requirements.

Scope of service

  • Roof survey, structural and irradiation assessment
  • System design optimized for your load profile
  • Support with procedures under current rooftop solar regulations
  • Supply of PV modules, inverters, mounting structures and protection devices
  • Installation, connection and acceptance
  • Online monitoring, panel cleaning and scheduled maintenance

Benefits for your business

  • Lower electricity costs

    Self-generated daytime power replaces part of the grid supply, especially during morning peak hours.

  • Support for ESG criteria

    Helps your business meet ESG criteria and reduce emissions, in line with customers' green supply chain requirements.

  • Cooler factory

    Panels shade the roof and lower indoor temperatures, improving working conditions.

  • Safe and durable

    Properly engineered with lightning and fire protection; scheduled maintenance keeps performance high.

Frequently asked questions

How many kWp can my factory roof hold?
It depends on roof area, orientation, structure and daytime load. As a rule of thumb, each kWp needs about 5 – 7 m² of roof. Our engineers calculate precisely during the survey.
What is the payback period?
It depends on electricity prices, self-consumption and investment cost. The payback period is analyzed specifically for each factory in our quote.
Will solar installation affect a metal roof?
The structure is checked before installation; dedicated clamps attach to the roof seams with waterproofing, without drilling the roof depending on roof type.
Can surplus power be sold to the grid?
Systems are designed primarily for self-generation and self-consumption. Exporting surplus power (if any) follows current regulations; we will advise on the right solution.
