On January 7, 2023, the ministry set the ceiling prices at 1,184.90 VND (5.05 cents) per kWh for ground-mounted solar projects, 1,508.27 VND (6.43 cents) for floating solar projects, 1,587.12 VND (. . The government is proposing a tariff of VND671 (US$0.024) per kWh for surplus power from the rooftop solar panels, with a proposed offtake volume of up to 10%. [pdf]
Vietnam’s Ministry of Industry and Trade (MIOT) recently introduced new ceiling prices for solar and wind projects that sell electricity to Electricity of Vietnam (EVN). The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects.
The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects. Vietnam’s Ministry of Industry and Trade (MIOT) has set new price ceilings for the so-called “transitional” wind and solar projects.
On 7 January 2023, the Vietnam Ministry of Industry and Trade announced new ceiling prices for solar and wind energy in the country, pursuant to which Vietnam Electricity (“ EVN ”) can now negotiate tariffs in relation to transitional solar and wind energy projects in accordance with Circular 15/2022/TT-BCT (“ Circular 15 ”).
However, the current Vietnamese solar PV market is estimated to be only around 5 MWp, with 80% off-grid applications in rural areas. Solar energy is not yet integrated into political energy development strategies, such as the national Power Development Plan (PDP).
In 2021, the data showed that Vietnam now has 16.5 GW of solar power. This was accompanied by its green energy counterpart wind at 11.8 GW. A further 6.6 GW is expected in late 2021 or 2022. Ambitiously, the government plans to further bolster this by adding 12 GW of onshore and offshore wind by 2025.
Solar energy in Vietnam is available all year round, is rather stable and distributed widely over different eco-geographical areas. Solar energy, especially in the southern and central regions can be used on average 300 days per year. It can be exploited to meet the two main demands: thermal and electrical power (To Quoc Tru, 2010).

Ginlong Technologies Co Ltd, trading as Solis, was founded in 2005. The Chinese company is listed on the Shenzen Stock Exchange and headquartered in Ningbo, China. The company focuses on the manuf. . A solar system’s inverter is the point at which the DC electricity produced by solar panels is turned into grid-compatible AC electricity. Typically, there are 2 approaches to in. . All of the CEC approved Solis Inverter range are Transformerless Inverters, which contributes to their high efficiency rating. With efficiency ranging from 98.3% to 98.7%, they offe. . Solis inverters are manufactured in China and have reached a significant scale of production meaning they are able to offer cost-effective prices. Indicative wholesale pricing Keep in m. . An important aspect of getting the most value out of a solar inverter is to choose an appropriately sized inverter to optimise the solar panel system efficiency. To read about the import. [pdf]
Solis now match the market expectation of providing a full 10-year warranty for their inverters. In the event of a Solis replacing an inverter, customers must bare the cost of returning the solar inverter to Solis Australasia, which is presumably to their Melbourne office.
Solis single-phase solar inverters have gained popularity in Australia and among users worldwide. These inverters are well known for their effectiveness, reliability, and consistent performance in weather conditions. Furthermore, Solis inverters have proven their excellence through applications by delivering performance and energy output.

There are 92 of Solis Inverters (under the name of Ginlong Technologies Co Ltd) approved by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program. The majority of the listed inverters are available in Australia.
In terms of residential three-phase inverters, the S5 GR3P (5-20) K series offers a range of options starting from 5kW to 20kW. Solis’s residential 3-phase inverter’s maximum efficiency is 98.7% which is much more impressive than their single-phase models.

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more. . Goals that aim for zero emissions are more complex and expensive than NetZero goals that use negative emissions technologies to achieve a reduction of 100%. The pursuit of a zero, rather than net-zero, goal for the. . The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply,. . The intermittency of wind and solar generation and the goal of decarbonizing other sectors through electrification increase the benefit of. . Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage systems. These batteries have, and will. [pdf]
With new incentives to start battery storage projects, the Wheatridge Renewable Energy Facility is, hopefully, the first of many of its kind from a utility company. Combining wind and solar with battery storage offers advantages over using either system individually. Hybrid systems like these can generate energy essentially at any point.
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
“Our results show that is true, and that all else equal, more solar and wind means greater storage value. That said, as wind and solar get cheaper over time, that can reduce the value storage derives from lowering renewable energy curtailment and avoiding wind and solar capacity investments.
Some storage technologies today are shown to add value to solar and wind energy, but cost reduction is needed to reach widespread profitability.
Indeed, the required storage power capacity increases linearly while the required energy capacity (or discharge duration) increases exponentially with increasing solar PV and wind energy shares 3.
For on-grid applications, combining wind and solar can also offer advantages. One primary benefit is grid stability. Fluctuations in renewable energy supply can be problematic for maintaining a stable, consistent energy supply on the grid. The hybrid system can help mitigate this issue by providing a more constant power output.
