 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.

PWM Regulator

Wholesale PWM Regulator (solar charge controller)

Pulse width modulation (PWM) regulator is essentially a switch(aka. Solar Charge Controllers) that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.

PWM is arguably the most effective means to achieve constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’s condition and recharging needs.

Advantages of PWM Charge Controllers for PV Systems?

Charging a battery with a solar system is undeniably a difficult challenge.

In the past, simple on-off regulators were used to limit battery outgassing when a solar panel produced excess energy. However, as solar systems matured, it became clear how much these simple devices actually interfered with the charging process.

The history of on-off regulators has been full of battery failures, increasing load disconnects, and growing user dissatisfaction. PWM has recently surfaced as the first significant advance in solar battery charging.

PWM regulators make use of technology that is similar to other modern high-quality battery chargers. When a battery voltage reaches the regulation setpoint, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery — and yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result of this is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.

Additionally, the PWM charge controller promises some very interesting and unique benefits. These benefits include:

  1. Ability to recover lost battery capacity and de-sulfate a battery
  2. Dramatically increase the charge acceptance of the battery
  3. Maintain high average battery capacities (90%–95%), compared to on-off regulated state-of-charge levels that are usually 55%–60%
  4. Equalize drifting solar battery cells
  5. Reduce battery heating and gassing
  6. Automatically adjust for battery aging
  7. Self-regulate for voltage drops and temperature effects in solar systems

A great deal of testing and data supports the benefits offered by PWM regulators. Additionally, manufacturers are continuing their own ongoing test programs to refine the PWM charging technology. As a result, over time, each of these benefits will undoubtedly be improved and more clearly defined.

Are All PWM Chargers the Same?

Many solar charge controllers that simply switch FETs differently than the on-off algorithm claim to be PWM regulators. Buyers should be aware of this because this is actually not true. Only a few controllers are actually using a PWM constant voltage charging algorithm. The rest are switching FETs with various algorithms that are cheaper and less effective.
