 Vietnam’s Solar Market Outlook

Vietnam, a developing country in Southeastern Asia, has seen a dramatic increase in energy demand in the last five years.  This rise in demand has subsequently fuelled the growth of the solar sector in the swiftly developing Asian country.  According to recent International Renewable Energy Agency (IRENA) statistics, Vietnam is among the top ten leading countries in solar utilization. This is pretty awesome for a developing nation, don’t you agree?

Statistics released in late 2020 reveal that Vietnam’s solar capacity stood at over 7.4 Gigawatts. This is positively surprising considering that the country’s solar capacity was only 4 megawatts in 2015.  The figure below will help paint a clear picture of Vietnam’s exponential growth in matters concerning solar energy;

Solar equipment supply capacity in Vietnam

From a solar products production and supply perspective, Vietnam has immense growth potential.  As part of an ambitious solar sector growth plan, the government of Vietnam has implemented flexible investment policies. These policies are primarily responsible for the rise in domestic and foreign producers and distributors dealing with different solar product categories.

It is also worth mentioning that Vietnam’s incredible port and logistical infrastructure have further strengthened its positive solar sector outlook. As stated by the World Economic Forum, Vietnam ranks at position 80 on the quality of port infrastructure. Do you intend to sell or buy solar products from the Vietnamese market? If the answer is yes, you can rest assured that you can safely transport any product to or from Vietnam.

I can confidently conclude that there are immense opportunities for individuals who intend to buy or supply different solar products in Vietnam.

Whether you are a solar installer or EPC, the SolarFeeds family is eager to help push your Agenda in the Vietnamese solar market.

Gel Battery

Gel Battery

All solar power systems are composed of solar batteries. However, not all solar panel system manufacturers and installers provide one solar battery type. Most of the time they offer different models of batteries. Generally, there are four main types of solar batteries that are paired with residential solar panel systems. The commonly used batteries are Lead-acid batteries, Lithium-ion batteries, Nickel-based batteries, and Flow batteries. Each of these solar batteries has its own characteristics. But among the four types, the most commonly used is the lead-acid batteries, and this type of battery also comes with different variations. 

For today’s article, we will discuss one of the lead-acid battery types, which is the Gel battery.

What is Gel Battery?

A gel battery is a common type of sealed lead-acid battery. The major difference between gel batteries among the other lead-acid options is the material inside. Generally, a gel battery is made up of silica in its inner electrolyte mixture, which is responsible for producing a gel-like substance. Among other lead-acid batteries, gel batteries produce more power. Besides, this battery is valve-regulated, low maintenance, extremely robust, and versatile.

Since the battery is also “sealed”, it does not require water level monitoring unlike standard lead-acid options, plus it does not expel gas. It only produces few fumes so it’s ideal to use in any place without much ventilation. These factors make it a safer option for solar panel systems than other traditional lead-acid options.

Advantages and Disadvantages of Gel batteries

Gel Batteries are becoming increasingly popular when it comes to solar battery choice due to their several advantages and minimal disadvantages.

Advantages 

  • It is ideal for deep cycle applications and the battery life span is ranging between 500 to 5000 cycles.
  • It does not require any high maintenance, unlike other batteries. 
  • Since it produces a gel-like structure, there will be no spill.
  • It has minimal corrosion making it compatible with sensitive electronic devices
  • Rugged and vibration-resistant
  • Safe option to choose. You’re less likely to suffer from sulphuric acid burns.

Disadvantages 

  • Among the other lead-acid batteries, it has the most expensive initial cost.
  • Water cannot be refilled if overcharging happens.
  • You are required to use special chargers and regulators.
  • Hot temperatures can adversely affect the acid, making the gel hard and may shrink away from plates.

Conclusion: Is it Good to Partner Gel Batteries with Solar Panels?

When it comes to solar panels, the most debated type of battery to partnered with solar panels are the Gel battery and AGM batteries. However, not all solar installations are identical, and there are several factors such as climate and discharge demands to consider when choosing what’s the best battery. 

If you’re going to observe, gel batteries remain on top as they provide many benefits to solar users for long-term energy storage. Although gel battery is the most expensive among the lead-acid batteries, it is free from high maintenance, making it still an ideal battery for solar users, particularly for smaller solar projects. 

On the other side, for most residential solar panel installation that requires high energy demand to power its entire household, you may consider exploring lithium-ion batteries like the Tesla Powerwall to cover all the high energy input from a solar panel system.
