With A Focus On Rooftop Solar For C&I Consumers, I And My Team At Tona Syntegra Solar Had Wonderful Opportunities To Implement Beautifully Complex And Quality RTS Systems From Medium-to-large Scale: Phuong Anh Nguyen – Chief Executive Officer, Tona Syntegra Solar


Reading Time: 4 minutes

In an exclusive chat with SolarQuarter ASEAN magazine, Ms. Phuong Anh Nguyen, Chief
Executive Officer, Tona Syntegra Solar spoke about how Vietnam has been an important player in the solar game in the region. She also spoke about the technology adopted and the latest rooftop work done by the company. We also got insights on the future outlook of PV Solar in Vietnam.


Vietnam is one of the promising solar destinations in South East Asia. What have been the contributing factors for the same?

Yes, Year 2020 set a critical path for the Solar PV industry in Vietnam when the country
became a PV Solar leader of South East Asia after having achieved the installed capacity of 19.400 MWp by 2020 end. This target was actually planned to record by post 2025 in the National Master Power Plan VII.

Among many critical facets in terms of timing, demanding, or supplying for the Solar PV
development recently, the following factors should be commended as most influential to
Vietnam PV speedy growth, namely: the abundant supply of irradiation, with the daily average DNI (direct normal irradiance) of 4-5 kWh/m2 across the country; the substantially increasing energy demand with the average additional 6,000 MW to 7,000 MW annually until 2030; the lowest average LCOE of Solar PV for Vietnam to pursue Low-carbon pathway aspiration; and ultimately, the incentive pol icy and regulations namely FIT1 effective in March 2019 and FIT2 issued on April 2020, whereby the 20-year PPA with EVN is at USD $0.0935 per kWh and USD $0.0838 per kWh, respectively.

Could you please tell us about the recent rooftop solar project works that you undertook in the country?

With a focus on rooftop solar (RTS) for C&I consumers, I and my Team at Tona Syntegra Solar had wonderful opportunities to implement beautifully complex and quality RTS systems from medium-to-large scale (i .e. below 1 MWp to 7 MWp systems) as the turn-key EPC across Vietnam. Most of them are large net-metering systems for C&I sectors with intensively high load consumption profiles, eminently demanding for safety, reliability and stability of electricity generated from Solar PV systems while strictly complying with EVN regulations of not exceeding 1.2 MWp per system and grid’s capacity during low load periods; concurrently without curtailing the output of RTS systems. Well , it has been an amazing path and motivation for us to accelerate the application of advanced technologies for our RTS projects.

How is the future outlook of PV Solar in Vietnam?

With the increasing energy demand and low-carbon pathway set, the future of PV Solar remains bright in Vietnam. Against this backdrop, a much stricter regulatory framework for the PV industry with al terms and conditions regarding technical standards and compliance will be rapidly effective, requiring all of the PV industry stakeholders to learn, share and comply. Furthermore, with current exceeding target installed capacity by 2020 end, I think a more programmed scenario with annually allocated capacity according to actual regional and/or business sectoral demand will be discussed to ensure the matching between Solar PV output and the infrastructure capacity for achieving the maximum system utilization once installed. Under any circumstances, the long-term safety and reliability of the solar PV system would not be traded-off, I believe.
