Posted: 06.04.2013, 09:29 Photovoltaics and feed-in possible in Vietnam

hello dear forum community,

The electricity prices for Vietnamese standards are quite high ... 6500 to 8000 dong / KWh.
Is it also possible to feed electricity into the grid with a photovoltaic system?

Best wishes
Thomas

Aren't the electricity prices closer to 1,500 - 3,000 vnd? In any case, this is not feasible with photovoltaics.
As far as I know, there is no feed-in regulation. So far there are actually only systems for self-consumption. Hospitals, hotels etc.
However, a feed-in law has been in planning for a long time. There are probably some companies waiting for a new law to then invest heavily in UN.

I pay around 2000 VND / KWH here in Can Tho.

But with the sunshine here, something should be worth it, right? But I don't know anything about that.

I don't have exact dates. But I could calculate if you are interested in it.
Feeding in solar power is certainly not worthwhile. It only makes sense for companies with large diesel generators to be able to compensate for power failures or in regions remote from the grid. In every village there are families with diesel generators who charge (car) batteries from neighbors etc. for a fee, which are then used for power supply. Since diesel is becoming more and more expensive in VN as well, it is already worthwhile for many to convert to small PV modules.

From June I will be doing an internship in a Vietnamese company that has recently also produced PV modules from its own production. Then I can give you more detailed information on market prices, etc.

Hello,
Thank you first for all the answers.

I would like to briefly provide information on what the question is aimed at.

It is not about receiving a feed-in remuneration or subsidy.
It's more about if I feed in 10 kW that I can draw 10 kW from the grid again for free (whether that makes sense or not is not my question here)

In the region I am interested in, the electricity price is higher than the 1000 or 3000 dong mentioned here
Just ask what the KWH costs on Con Dao.

Since I would still have the opportunity to create a self-sufficient system that is operated with PV and its own batteries (but these batteries are still very, very expensive)
I asked about the possibility of feeding in electricity and drawing it again.
Is that possible?
1 to 1?
Greetings Thomas

Hello Thomas,
what you are talking about does not work in this form in VN at the moment.
There are subsidies for solar systems, but not for you (us foreigners).
The subsidization is subject to special conditions, I am sure that you cannot fulfill any of them for your project.

It makes much more sense to install an island solution, besides batteries there are other possibilities for energy storage. (HHO e.g.)

As an example, I will mention a modern adsorber refrigerator, which can be heated directly with solar power without conversion, with 230V ~ and even with HHO.
The hobs can be operated with HHO without any problems, I recommend a copper insert to make the flame visible.

The energy for TV, PC, LED light, etc. is easy to handle in small storage facilities with an investment volume of less than 2000USD for several parties.

A very good 100A charge control with MPPT technology was implemented by in cooperation with the Technical University in Hanoi for less than 200 euros.

So all in all not a thing and feasible for little money.
This can only be calculated from currently approx. 14,000vnd / kWh (currency losses not taken into account) for at least 16 years with a 10KW system.

My conclusion: in the current uncertain situation, especially with regard to the rights of foreign investors, uneconomical, too expensive.
In terms of comfort, supply stability, the global energy and garbage situation, a must.

wow ... sau-cheap, I read here in the forum that electricity on islands like Phu Quoc should be more expensive ... around 8000, - dong

ups ... I made a mistake ... Can Tho is mainland ,,, I meant on an island like Con Dao. Think if it costs around 8000, -Dong per KWh in Phu Quoc, it won't be much different on Con Dao ...

Hello,
I believe you from my word. I didn't think of subsidies either.
I would only be interested in a 1 to 1 solution and the question was aimed more at the technical feasibility of whether the Vietnamese allow a feed ... so 10 kW pure results for me as a consumer again 10 kW for 0, -Dong

So stand-alone solution sounds great
don't know HHO at all ... I'll find out more about it.
Thanks!!!

Wow, thanks for this info ...
So there is also an affordable option if you need electricity 24/7 with almost 100% security.

I don't want to have much to do with fluctuating power grids (now and then failures) in energy costs or other dependencies.
That would be an ideal solution

The market seems to be slowly rolling. After a few other countries (Thailand, Indonesia, China) in the region, Vietnam now also wants to focus more on renewable energies.
Plots for wind power and photovoltaic systems were put out to tender for this year, a little south of Nha Trang. Overall it seems to be at least 140MWp PV and 60MW wind.
The first talks have already taken place, preliminary contracts have been partially concluded. Apparently they have agreed on a purchase price of around 15 cents per kWh, plus blatant reliefs such as duty-free imports and 10 years of tax exemption.
If this really happens this year, that would be a really big step for Vietnam in my opinion.
The largest PV system known to me that has been connected to the grid so far is a 110kWp roof-top system in Hanoi. So hardly worth mentioning.
It will remain exciting in the coming months / years.

Posted: 04/17/2014, 21:39 Search also for a plant for my commercial project.

Unfortunately, I have to adjust the monthly consumption at the moment, but I know my monthly costs of approx.

I'm thinking about whether a solar system for electricity solves two problems on the roof of a commercial property (restaurant / bar) in Ho Chi Minh City.

Avoid blackouts and keep costs under control.

System approx. 10kw although I haven't calculated that yet.

How expensive is something like that in Vietnam and already mature. There are already good companies that can build something like this!

Is that a photovoltaic?



I photographed Crazy House on the roof in Da Lat.

What does a photovoltaic look like? . Do you have photo?
