Let's continue in the existing thread.

It's a sub from the pub.

Second link also appears to be mono. Global have poly 340W @ 3790 Baht. Do your Baht-per-Watt sums and order the best bang for your buck. I did buy a few panels from Lazada, one arrived broken and I spent ages unpacking the metres of bubble wrap. Mostly I just ordered a bunch from Global for collection, paid online, they called when they were ready to pick up. In the back of the truck with cardboard in between (cardboard supplied by Global) for the 15 minute drive home. No unpacking and no waste bubble-wrap to dispose of.

It's a lot more than one would think, remember that your "4m3" truckload is uncompacted, by the time it's been compacted it may well be half that ???? If you can find a contractor who will do it as "raise this land by 1m after compacting" you reduce the risk of having to shell out further $$$ when your estimate comes up short.

Yeah, it will fit Thai outlets just fine. The problem is that the cord exits from the side when inserted in a regular outlet preventing you using two in a double outlet. The (defunct for now) Haco P001 and P002 had cords which allowed two plugs in a double outlet.

I am saying nothing!

Related Anecdote. Once upon a time in a country far, far away (OK Rome, Italy, just after 9/11) I had my UK passport stolen! (Along with my PC and other stuff, seems you can open a Fiat Punto with a blunt teaspoon). Trotted to the local cop-shop with an Italian friend and made a police report. Hot footed it to the British Embassy with said police report. Filled in a form, I had photos (Italy is as bad as Thailand for wanting photos). Paid my xxxxx Lira. Collected my new, 10 year, passport that afternoon. Life really was simpler then. EDIT Said passport wasn't "machine readable" which did cause me some issues with a certain "united" country I could mention

Let him have his way if he wants poly, keeps him happy and hurts nobody. I would however insist on half-cut (no, not 5 pints of Stella) panels, they are slightly more efficient and rather more reliable than regular panels.

Sparks is less than correct, poly is less efficient at converting solar to electricity, but who cares when the input energy is free? Poly have been around a long time, durability is a given. That said I don't see mono as being any less durable. If you like the cool, black look of mono ...

With no space restrictions I'd go poly and have more of them.

I'm afraid that genie is well and truly out of the bottle and into the bong!

By accident or design??

Whilst planning your house ensure that your car-port is oriented north-south with the roof sloping towards the south. You need somewhere for those solar panels

Our south-west corner (spare bedroom) gets the most solar radiation. Lots of trees in the way now after Madam went on a planting spree. Our bedroom on the north-east corner is pleasantly cool by the time we retire for the night. The coolest room in the house is our en-suite bathroom on the north-west corner, it gets pretty well no direct sunlight at all.

Ditto, I was right on the end of the "force right-handedness" era in the UK, luckily grammar school was more, er, progressive.

Our outside floodlights have a 150W solar panel feeding a 20A PWM charge controller and about 30Ah of 12V LiFePO4 batteries (batteries are made up of a motley selection of 32650 cells acquired over the years). I noted from day 1 that the charge current wasn't quite what I expected, but it was filling the batteries so I put it down to the el-cheapo PWM charge controller. Fast forward a few months and I see the lights are not making it through the night and the batteries are nowhere near full at the end of even a nice sunny day. Changed the charge controller - no difference. Tracing the wiring back to the panel revealed:- Evidently warmth had been generated over a period, that wire was hanging on by a couple of strands. The screw terminal was decidedly not tight! Since the plastic cover was melted and brittle a new one was fabricated, that's just a regular plastic electrical box that was in-stock, not even new. It looked a bit manky so I sprayed it with black acrylic. Connections were tidied up and proper crimps used on the cables. Under test before I install it back onto the patio roof. So, it wouldn't hurt to verify your panel connections are good before hauling them up onto the roof.

Employ a local! If you really have to do it yourself pull the live at the meter output (turn off all loads first).

The cheapest RO I've found is from Close (never heard of the brand) and it includes UV for around 3,500 Baht. https://globalhouse.co.th/product/detail/2011172029956 Not sure if I would buy down at that price point but it takes standard cartridges.

We have a mid-price Mazuma (a known brand), 3 stages (particulate, carbon, resin) + RO + finishing carbon (no UV). I think the latest version is about 8k Baht. Never replaced the RO membrane, been going 10 years. A full set of genuine Mazuma filters (not including the RO membrane) is about 1,500 Baht, off brand ones can be much cheaper. I change the filters when Madam says the water tastes "bad" (I can't tell any difference), I just replace the carbon and particulate, our water isn't "hard" so I don't bother with the resin unless it's on offer with the others. In reality the filters get swapped out once a year or so. We have a whole-house crunchy-bits filter which catches the big particles before the water enters our storage tank, I change that when the tank becomes slow to fill, it's usually the colour of very stewed tea by then.

The RO membranes do have a long life, it's the particulate / carbon / resin combined filter that needs regular replacement, and of course you can't just replace one element if, say, the particulate filter gets clogged. It's all in a nice compact box if that's what you like, but it doesn't seem to do anything that a 4000 Baht Mazuma or whatever does.

The AUT3234 is not RO. The AUT2015 is RO, not sure from the data if it has a built in tank or what. The AUT7000 is RO, it has a built in 8L tank with UV. I would look very carefully at the cost of the replacement filters, they are non-standard so you are at the mercy of Philips to keep making and supplying them.

New tube, new ballast, new starter and it won't ignite = low supply voltage (actually measure it at the fitting, you can't guess here) or a wiring issue.
