Residential Solar Power Suppliers in Korat
« on: April 27, 2013, 08:40:27 PM »
Hi, Members, Just a short question? Is anyone aware of any suppliers or companies in Korat offering deals on residential solar power deals.
For those who are a little confused, the solar systems on sale in OZ are an arrangement of solar panels attached to a roof that draws energy from the sun and that energy then travels through an inverter which powers your residence saving you using the power supplied by the power company, and in some cases any excess power that you solar system generates above your normal usage goes back through the power companies grid in effect reducing your power bill to practically zero.

Here in Australia for any excess power sent back through  the electricity companies power grid/lines you not only have a reduced bill, they actually pay you for the excess, the only charge you see on your bill is for the connection and rental of the meter which is next to zero.

I was wondering if anything like that happens in Thailand and for that matter Korat or is it something they may have planned for the future like 3g or 4g internet?

Love to read any comments/replies
Cheers Jonesy.

The nearest business I could find was in Phuket. The system cost THB500,000 and wasn't sufficient to power the whole house on a normal day. In addition to that, the bank of batteries would need to be replaced every two or three years.

I was told that I could feed any excess power into the grid but would nit be paid for it.

Given the cost of electricity here, there is, as yet. no cost justification for solar power.

Hi Saf, thanks for your reply, that sounds like an absolute rip off! half a million baht!! that's nearly 17 thousand aussies dollars :-[
We have 4kilowatt  systems available here in Australia for $3,000 AU installed that will supply enough power for a house full of air conditioners and still send the excess back to the power grid so you don't get a bill.

I would say that is (the old Farang Price versus the Thai price syndrome)
Since I started this thread I discovered that there is a company in Korat called GRENZONE http://www.grenzone.com/ who supply and install a 1 kilowatt system for houses for $150,000 Thai Baht - nearly $5000AU but with those systems you would be lucky to be able to power a TV, fridge, washing machine and electric kettle,.

My wife phoned them from here in Australia so I would hazard a guess that we got the Farang price.

That leaves me with no other option that to make the solar panels myself, buy an inverter and have a sparky install it at our house Korat.
They are easy to make and anyone with basic carpentry skills and knows how to use a soldering iron can make them, the only real expense is the solar cell film which is made in Thailand and China.

I have complete illustrated DIY plan sets of how to make them from scratch, free to any member if interested or you can Google and download the plans for around $20.00.

You could then sell them ( the panels) to the Thais.................. for a special price of course hahaha! :)

Saf, you are right. The concept of using solar panels to charge batteries is completely illogical.  As you say, the battery life is only 2-3 years.  You can get 10 year battery life by keeping them in a 25C air conditioned environment but the solar panels cannot provide this amount of power.  This is all a nice sales con pitch to people who think they are "saving the planet."

Too true Tamun Tun, that's why its best to stay away from using batteries to store the power and instead use an inverter that connects to your household wiring system and electricity companies grid, regardless of whether or not the electricity company pays you for your excess you would still reduce your power bill and in turn use their power to run your air conditions in the hot season.

Far from saving the planet, domestic solar systems increase the activities of eco-unfriendly battery manufacturing plants and encourage the dumping of defunct batteries.

How much electricity over how many years do you have to produce from the system to recoup the initial outlay and the cost of replacement batteries?

Perhaps I don't know enough about this but without batteries I assume you could use solar energy only while the sun shone. At night time you would have no solar-generated electricity. If that's so, for the same capital outlay, you would be generating less electricity and using more from the grid. That would make the exercise even less cost effective.

What Jonesy asked is for example mandatory in Germany for privately run wind turbines: you have to feed excess generated into the grid, but I don't think you get much for that. Don't know about solar-generated though. But I can imagine it to be the same. So his question is fully understandable to me. I'm also interested in finding a valid and comprehensive answer regarding Korat. But at the moment I'm not planning to actually install solar panels or even a wind turbine. And until I'm financially able technology might have advanced again.

The problem with electricity around here is that too many houses' wiring systems haven't been set up by people who actually knew what they were doing or what material is suitable. So others are suffering from almost permanent ground-faults and cross-currents. Not being fed by the grid, but by your own generator, were the only way to escape that. But the costs given as estimates on the forums aren't encouraging at all...

Afternoon TT. I was trying to follow the thread, but didn't understand your 08.37 response too much.
As an expert, what would your advice be about Household Solar Power in Korat ?
I remember visiting Turkey (Olu Deniz) 10 years ago and was impressed that nearly every house had a couple of panels and a tank on the roof! Not suggesting that's what I might want here.
But - any viable options you know of for Korat ?
Thanks.

No not at all, I do not and never have assumed that I am that I am dealing with hicks from the sticks or that I am an expert on solar energy, so congratulations on your qualifications, maybe you can offer everyone some more positive advice than I tried to do

I won't ask what "electical" is! It's an official Australian term used for electrical installations. :-[

Roger, what you  saw in Turkey was a means of heating the water.   Good idea. No photo electric cells, batteries or inverters.  But in Malaysia/Thailand do you really need to do this?  Good to start the day with some nice cold water!

Yes TT I agree. Cold water is good ! Is there a viable way though, to get domestic solar energy here ?
Incidentally, have you seen the 'solar panel farm' opposite the Korat Resort - opened about a year ago - maybe 50 Rai ?
Wonder if it makes money ?

Do you mean this one 10 km south of Phimai directly at the A2, opened 2 years ago? Unfortunately it is forbidden to take photographs there. So, here an official photo:

According to that article there are even more in Korat:

No Johnnie. This one is on the way to Chok Chai, turn right for the Zoo, 1km. Close to Korat resort.
Looks very similar to your picture.

Here you go jonesy

Graphene paint could power homes of the future

Houses could be painted with a new super-material that generates electricity from sunlight and can even change colour on request, following new research



Scientists at the University of Manchester used wafers of graphene, the discovery of which won researchers a Nobel Prize, with thin layers of other materials to produce solar powered surfaces.

The resulting surfaces, which were paper thin and flexible, were able to absorb sunlight to produce electricity at a level that would rival existing solar panels.

These could be used to create a kind of “coat” on the outside of buildings to generate power needed to run appliances inside while also carrying other functions too, such as being able to change colour.

The researchers are now hoping to develop the technology further by producing a paint that can be put onto the outside of buildings.

Thanks Thaiga, Very interesting! If I could paint the roof the Graphene green colour I would change my forum id to "Kermit of Korat".............Just Kidding :)
Its a very interesting concept and I hope it comes off. Recently we got a quote from a supplier installer in Korat for a 1 kilowatt solar system for 150,000 baht, must have been the Farang price though.

I would imagine paint has to be a cheaper alternative to solar cells and I hope the idea works and takes off

Cheers,

Jonesy.

Quite a few have sprung up in the last couple of years,,,,a very big one  3 or 4 times bigger than the one near the Korat resort one on the side of the Highway 24 is probably 75% complete with another pretty big one that is operational on the side of the Nang Rong-Buriram road

When I stand on the balcony of my Condo in Sin City ,there were 3 houses visible that ALL had 6 solar panels on their roofs for at least 10 years,,,that is until quite recently when I noticed ALL the 3 properties had had them removed.

Just a couple of hours ago we had somebody post important, i.e. urgent, information (in German) to this topic on Korat-Info

Until Oct 11 this year one needs to apply to get a contract on this in Korat and adjacent provinces. If granted, you'll receive 6,96 Baht per KW/h you fed into the grid, price fixed for 25 years for systems up to 10 KW/h feeding capacity.

The application forms are available at the office building behind the substation on Mitraparp towards Bkk, past Save One, Ratchasima School, Shell-station, opposite ESSO. On the first floor there is a leaflet (in Thai only) available that informs about the necessary documents.

The poster (Wolf) wrote that for the moment it isn't important whether the system will actually be built or not. Townhouses will not get a contract.

Wolf offers to do the paperwork (Plans etc.).

 Hello folks,

with great interest am I reading articles and discussions in this forum. The topic "own solar power systems" has become more interesting in the last years even. Are there any updates, experiences, from people who actually installed and operate their own systems?

Thanks in advance,

Warnard
