Solar panel advice & experiences

[stoneinfocus]

Our new house is in Buriram, and the PEA have failed to supply us with enough power (180v). They're saying they'll sort it, but I've had enough (3.5 months already). Some of my equipment won't operate properly, as you can imagine. 

 

We use about 400 units a month on average (less in winter) so what do you think might be the best way to proceed? I don't think ditching the main grid completely is the answer, as most of the time it's not an issue.

It would depend on what equipment you want to work, that doesn't work now.

Well, specifically, my hi-fi equipment! The massive integrated amp' actually works fine, but the stupidly expensive CD player gets upset if someone turns on the tap, thus causing the water pump to kick in. 

 

Thing is, I do sometimes want to listen after dark, so some battery storage may be necessary.

I think you should have a look at this topic!!

Cheers for that. 

 

So do you solar boys incorporate an AVR? 

 

PEA rang my wife and assured her that once their crane is fixed, they'll be right over!

I don't have an AVR, but I have all my "important" devices like fridge, PC, Modems, TV's, NAS etc connected to an Individual UPS.

 

I often hear them clicking, which means that the voltage they are getting from the PEA is too low and they are compensating for it but no issue for the appliance connected to it!!

 

Here we often have brown-outs that only lasts for 1-5 secs and that is (AFAIK) very bad for appliances!!

I gots to be honest, I regret spending so much on my <deleted> hi-fi.

Don't one day you will absolutely enjoy it when the PEA fixes your problems!! And that is priceless IMHO!

I'd go the two-pronged attack. A small AVR to solve the low-voltage problem for the Hi-Fi followed by a suitable UPS if you have brownouts so that your listening pleasure is uninterupted.

 

That won't break the bank.

 

Then once PEA have done their worst start looking at solar, your usage is pretty small so you should be able to DIY something to get your bill down to close to zero.

I once managed to put together a bed frame with allen keys, but that required some really good headphones and The Orb's Adventures Beyond The Ultraworld turned up to 8.

Don't worry @Crossy even wants me to connect my Solar Panels/Inverters/Batteries myself. I think he wants to make everyone a Electrical Expert ????

Red to red, black to black, if smoke comes out then go back

 

Seriously, it's not rocket science and with the help you can get here ...

 

I'll even get @MJCM on line (if he can get his good sparks off the bottle for a few hours) ????

If it's not rocket science why are you making the big bucks then ???? and why is it so hard to find a good Sparky.

 

We were waiting at our old house for the delivery of steel and we were talking to the son of our neighbor who is learning to be a sparky (he is in his 3rd year)

 

Was talking about ไฟฟ้ากระแสตรง  - DC and ไฟฟ้ากระแสสลับ - AC and he had no idea!!

 

And bear in mind that I have no education whatsoever in Electric!! Maybe something went lost in translation, but we were clearly talking about Solar, and he in his 3rd year must know for sure that it is different then electricity what the PEA brings in!!

Sure as heck not helping people out on this forum (and not in my day job either).

Tech college in Thailand is more like reform school in the UK.

I don't think they teach them much, they all make zip guns in the workshop.

More about keeping them from fighting in the streets.

The only thing we wanted to express to him is that he needs to learn more about Solar maybe specialize in that and not only be just another "Baan Nork" sparky.

 

We would help him to setup his business (money wise) but it all (sorry to say) was met with blank stare. I think he is more interested in be able to fix his old SFH (Speakers from Hell) system (you know the ones that have does headache splitting Bass coming from them) ????

Yeah, I might just allocate the solar money to another project: an anechoic chamber...

Look for a voltage stabilizer, There are big and smaller ones , depending on total power you want corrected.

You can also do per electric item and have their own stabilizer for the used power (Watts).

More and more you see in electric items, buit in power supply which can handle then from 180-230volts or even from lower.

Inverter and  gel battery around 9,000bht.

I have this plugged into the socket between the mains and my entertainment.

Works for 2hrs if no electricity at all, and forever if it's just momentary interruptions.

(TV, computer, router, speakers, XBox 360)

 

This one, 4000bht

And a 12v 100AH battery 4800bht

You don't need solar at all .......... this switches itself from mains to battery as required.

Yes, the panels will require cleaning every so often, depending upon how dirty they become.  Lets say in the worse case scenario they need cleaning once a month.   A bucket of water and a soft brush plus 15 minutes of time at 50 THB/hour will give a grand cost of say 30 THB /month or 360 THB /year.  Not really going to break the bank.

I do not have a solar power system yet, but am seriously considering one for a new house build in Isaan.

I am doing the house design myself so want to leave room on the roof for PV solar panels and access to them.

 

Is that really the only maintenance panels require?

Yup, unless you get a failure (rare) or a panel gets damaged you won't need to access them other than for cleaning.

 

Our panels are on the car port for easy access.

I would second @Crossy comment above.  Panel failures are rare and more likely to happen shortly after installation (manufacturing problem). 

 

Periodic cleaning required if panels get very dirty during the dry season from dust etc or occasional bird deposits which can reduce the panel's efficiency.  So giving some consideration to accessing the panels for cleaning would be advantageous.

 

FYI... For cleaning the panels it is recommended to just use a water, a soft brush and a soft rubber squeegee.  Do not use a power washer as the pressure from the nozzle can damage the seals.  It is also advised to avoid using detergents or proprietary glass cleaners as these tend to leave a fine film on the glass which actually attracts dust and dirt.

 

My panels are located on the car port roof and are some 4 plus meters above the ground, with the roof sloping at 15⁰.  Although 75 YOA, I'm fit and able to get up there and clean them as and when required, but inevitably there will come a time when 'mountaineering' will no longer be possible, so luckily the second floor balcony overlooks the car port and panels so I or my better half will be able to give them a good hose down.

Good luck with your build.

I use a 250 litre storage hot water system with a timer to isolate outside daylight hours as an "energy storage" from the solar panels.

Can add up to quite a lot over a 12 month period. More in winter months but approx. $400 per annum.

As an example, the feedback rate in Aus is currently around 6 cents a unit, whereas consumption rate even on off peak tarrif is around the 22 cent mark.

More in winter months but pre-solar cost was approx. $400 per annum and virtually maintenance free.

Last storage unit here was replaced only due to the flood and was over 25 years old, cost AUD$1,000.

Water quality is rather good though as others in different areas of the same city replace every 10 years or so due to being eaten out with rust or not replacing the anode when required.

Looking at a similar arrangement when building in Thailand.

Any links to current Thailand domestic no-feedback solar install costs?
