The Good-ole US of A did actually try, the bill failed but ...

@eddysaccwhich inverter do you have?

There have been a couple of rather vague reports of Thai digital meters charging for export, I've also seen it reported on other solar forums not just in Thailand. I suggest checking if the meter is counting up when you know you are exporting! Just turn everything off around lunch time when the sun as at peak output.

The results of our semi-scientific study. Background Myself and @JAS21 live about 20km apart as the crow flies, at this time of year there's no localised storm activity so we get broadly similar weather. Although our systems are of different capacities the panels are oriented in roughly the same direction and angle. We also tend to clean our panels on a sort of regular basis. The factor we used to determine if cleaning made a measurable difference was Total Daily Solar Generation which would be in kWh. What we did Testing took place over two 2-day periods. Period 1 - 27th and 28th February 2023 JAS cleaned his panels on the morning of the 28th, I did nothing (my system is the control or weather-reference). 27th JAS = 21.92kWh Crossy = 40.60kWh 28th JAS = 23.31kWh Crossy = 38.30kWh The reference output went down by about 4.25% If we apply that factor to JAS output on the 28th we get a corrected output of 24.71kWh. So, the effective change from cleaning is about +12.7% Period 2 - 4th and 5th March 2023 This time I cleaned my panels on the morning of the 5th and JAS did nothing (so his system is the reference) 4th JAS = 23.22kWh Crossy = 35.9kWh 5th JAS = 22.39kWh Crossy = 37.9kWh The reference output went down by 3.6% Applying that factor to my system output on the 5th gives a corrected output of 39.30kWh So, the effective change from cleaning is about +9.5% Conclusion It's not a particularly good test methodology and neither set of panels was particularly dirty (JAS panels were probably a bit dirtier than mine), but there does seem to be a correlation between cleaning them and a not insignificant increase in output. Of course, this does assume that I've done my sums correctly, which is why I've included our measurements if anyone wants to pull my maths apart ???? We will do the same test again when we clean again, actual schedule hasn't been decided as yet, probably about a month unless things look particularly grubby.

Yes. Very good point, we have had reports that digital meters have been charging for exported energy as well as import!

Possibly. Did you use a registered installer? Is your inverter on the approved list? Not sure if this is the absolute latest list: - https://www.pea.co.th/Portals/0/PEAContent/eee/aee_div/reg_equip/PEA Inverter list 6-2565.pdf?ver=2022-07-21-181114-117 If either is "no" then getting a solar friendly meter probably isn't going to happen ???? But it sure as heck it can't hurt to ask. Otherwise, time to shift your lifestyle to use all your energy during the day, washing, ironing, charge the EV.

Nah, THIS is a shameless bump!

Yeah, Madam does something similar, whole fish filled with assorted herbs and stuff and including a secret ingredient. Wrapped in foil then gently cooked on the griddle. She calls it "Happy Fish" because the secret ingredient is my JW Black! ???? (We did try JW Red but it's not quite the same).

Spectacles from the US should be 5% duty + 7%VAT on the CIF value. If sent by a regular mail system rather than a courier you may get away with being charged nothing ????

Yeah, that frozen white fish (Pangasius?) is pretty tasteless and has massive amounts of water. They do have Barramundi ($$$) and Tilapia ($$) both of which are much nicer without having to flavour them up with curry sauce etc.

We get them (and little black flies) sometimes too, annoying. Leave your A/C on "recirculate". A good spray of Raid (or similar) when you close up at night should handle them, the smell will have gone by morning.

I'm conducting a "somewhat controlled" cleaning experiment with another member. Results here when we have something useful.

Right now, things are on hold due to financial circumstances (waiting to sort out a new contract). Watch this space ????

If you give us a clue as your expected usage (with day/night split) and how much space you have for panels. We can give you a guesstimate. Can you go all week on one charge of your EV (top up from solar at the weekend)? Solar here does pay back, having a hybrid inverter with storage can extend the ROI significantly, using a contractor rather than DIY can make it even more expensive. If you can get on the Thai feed-in-tariff that could enable you to balance your TOU costs without using storage! How long do you expect to stay in your home? Once you have covered your costs the energy truly is free! Expect to break-even in 4-10 years.

Yeah, it looks like a mono-bob.

Echoes of Cool Runnings. Very well done young lady ????

Exactly ^^^, once we got rid of the floods the garden has been bone dry, barely a drip of rain.

I saw an Atto in the office parking last week, looks rather nice. Need to find out who it belongs to. I like the look of the BYD-e6 but you have to go to SATR as the importer (they import the BYD fork trucks, vans and buses) as it doesn't seem to be in the dealerships. A mate bought a BYD van from SATR earlier this year, his wife loves it so he still drives their MG ES. The Atto has a 60kWh pack, say 48kWh to charge 10% to 90% so about 130 Baht at cheap-rate TOU. BYD also use LiFePO4 batteries, which are less liable to go fzzzt than the Li-ion packs and their "Blade" batteries are easily serviced if a cell fails.

Pretty much. TOU timings and tariff are on the PEA website. https://www.pea.co.th/en/electricity-tariffs Nothing to stop you using a timed automatic transfer switch to move night loads over to the other meter, the car will be sucking up to 7kW (32A) so a 15/45 leaves you with around 2.5kW (say 25,000 BTU of A/C with lights and technology) to play with.

There's a rapidly increasing installed base, not just domestic but the big retail places have realised that they can offset their A/C (and the shading reduces the load too).

The choices from MG are good value, BYD of course. The GWM Good Cat is very small but not the cheapest. If you get a dedicated meter for the EV (talk to PEA) you can put it on TOU (Time of Use) and get very cheap power overnight! You can charge off a regular outlet (granny lead) at about 2kW. If you don't drive far that could be enough but I would get a "proper" 7kW charger. And, of course, get those solar panels up for truly zero emissions and free motoring!
