  1. Smart idea ... just put some panels and a cheap inverter . Later on , you can extend the system if you wish to do so and you can do it with the money you saved from the electric bill .
  2. That certainly is a difficult question . IMHO , for the next 6-12 months , i would certainly guess rising prices . This thx to inflation and energy costs rising in several parts of the world ( Europe) . Together with also electric cars ( sales numbers there very high , creating shortage on batteries ) i would expect for the coming y higher prices . On the possible lower price i can see only 1 thing . That is a big crisis , meaning the inflation together with energy crisis , will make the economy totally grinding to a halt .There are signs that it is happening right now , but lot's of money is still flowing to renewables . On the other things needed for a installation . Inverters will go down in price and newer models will come out . Chip shortages are still a case , but i expect this to slowly recovering .Batteries are a different story . They will almost certain go up in price . Battery shortage is already the case for cars , and lithium prices are rising for a while . If you check the situation and will invest now in panels then it is needed to ask yourself more questions . A will you go with the battery option , it is the best , but also the most expensive . Solar panels are 2nd most expensive item . Having them already , you can already be saving electricity just by adding a supercheap inverter . Even when they are not ideally installed and everything , solar panels will make electricity if they see light .
  3. on 400 V system , 40m , 4mm2 is about 1% loss , so ok . https://www.solar-wind.co.uk/info/dc-cable-wire-sizing-tool-low-voltage-drop-calculator
  4. Do you really need 100m ? 100 m is a lot , how far are the panels to your inverter ?
  5. They are cables . You do have 4mm2 and 6mm2 . In case your panels are wired in series and are not far from from the inverter ( every m more you get more losses ) 4mm2 is good . In parallel or long distance to inverter , then it is upto 6mm2 .
  6. Well , panels are pretty sturdy , as they are able to withstand years and years of weather , including hail and storms . I'd say , leave them in the carton , and put them straight up against a wall . Things to look out for are , somebody walking on the panels (like a adventurous kid) and any light on the panels will create electricity . That electricity can potentially start a fire , inside the carton it is certainly no problem . In case you unpacked them already , face them front side vs the wall and make sure the wires ( connectors) can't touch anything .
  7. Most panels will create higher voltage , but not that much rise in amps , in fact , i did not see a lot of +11 amp panels as of yet . I think your panels will be like 46/47v and around 9.8 amp , maybe up to 10.2 .
  8. Those are 2 strings , each with it's MPPT controller . They can be other side of house , or other angle . Inside the power will be combined , to create 1 flow of electricity . The strings on this type of inverter is series creating high voltage . In this case , per string each 600V maximum . The voltage of the panels is always mentioned under VOC ( the highest number on the spec ) . So if you got 10 panels in series , and lets say they are 46 V , then you got a 460V string . However many panels on the market are still like 350watt panels , so in that case you would never be able to reach the 5000W output . So in order to get it , a 2nd string can be attached with also a number of panels , creating higher output .
  9. Battery started cables are a good cheap source also , available anywere , for a few 100 baht .
  10. Correct , however , there are lightning strikes on homes every single day , and i do know people who did have it . There was no solar installation there , but that is beside the point i think . Problem with solar is that there are high voltages , and they do keep on generating electricity even when the house is completely on fire ( many times dangerous for firefighters these days , as are the lithium batteries when there is a fire in them ) . Surge protectors are near the cheapest item in a solar installation , only a few 100 baht . For that price , why skip on it ? Taking a 50k to several 100k of installation and then let some extra safety let go for a few 100 baht ... I am all in for saving some money but for that amount of money , i wouldn't skip it .
  11. Make the formula much easier ... installed power X 4 . In this case its 3630 watt (11 x 330) X 4 = 14.55 kWh .
  12. Time and date at the immigration counter does count for immigration . So how long you travel towards there does not matter . Also , before you did get a 1 day free overstay , idk if that still is the case . I had it once and they did actually changed the stamp to the day before .
  13. Even if it a few Baht , or even free , provided by you , they many many times forget it , and/or do not add it while you did ask them to . 2nd reason is , are you 100% sure it is damp rising ? I mean , most houses to get water on the wall , from various sources ( the rain itself , aircon condensate , bathroom ..... ) . You only need a sip of water going inside the wall , it will make the paint peel off in blisters in a few years . Especially on outside wall , many times the lack of waterproof cement , together with the splash of rain , will make the wall suck up water . Easy to fix , depending on the situation , yes or no . Anyway , most of the times it is no big issue , unless you are working with gypsum boards . Gypsum does not like water at all ( or is it opposite ... ) .Cement doesn't care about water . Yes you do get peeling or fungus , but there are products for it , and besides requireing more frequent repaints and uses of fungus treatment , there is no issue ( prob the reason why they do not use the waterproofing at all in the 1st place ) .
  14. All of them pretty equal and they mostly stock same items also . I have used and gone to Globalhouse , Thai Watsadu , Homehub , HomePro , Boonthavorn , HomeMart . TW imho is the best of selection but it is very close to GH . Homehub , i did go in a few times , but since it is further for me i rather go to 1 of the others . Homepro , nicer shop , but that's only display , smaller selection and maybe in general the lowest of qualities are not there . Boonthavorn is different . Much much smaller selection unless you want tiles . It is nr 1 for tiles , and by quite a large margin . Also decent furniture there , for general hardware not recommended , but for tiles or better quality items in bathroom or lights or furniture , it is a good choice . Homemart , by far the least , and not recommended .
  15. No it is around and this year a lot (in Europe) . However there is a huge outbreak going on , but since most are vaccinated and came in contact with Covid before , the health risks are increasingly less then before . I had covid last month , and on the place i work , i know and heard of several others who are home with positive covid . Many aren't in the statistics anymore , since hospitals are in no way in trouble anymore . Maybe some companies get in trouble because too many get it in too short time frame but that's about it . This will be the case in all other places in this world also . Is covid away , nope , it will never go away anymore . Will it stay a issue ? , well no because it is less and less dangerous .
  16. solar panels can stand normal weather including even heavy hail or high wind speeds . Missiles and rockets , are not included in the tests , and no , they do not survive it . This post is useless , since if anybody here is involved in missiles and rockets , they are not interested in "how are my solar panels doing" but rather in surviving themselves . In order of normal weather or even very heavy weather , yes they will survive most of the time . Standard hail or storm is no issue , storms who do bring down homes , and hails the size of eggs , well thats different , but then it is all looking on how the home survived itself . Solar panels are strong , as strong as normal homes , not bunkers ....
  17. Some commercial solar farms already use similar tech to heat up salt , creating 24h solar energy ( solar to heat , heat to hot salt melted , melted salt to water , water to steam , and steam to power a classic turbine ) . This is possible in lower scale also , even with less heat , using sand ( you lose a lot of power since most energy is stored in phase shifts, solid to liquid and liquid to gas) . However , scaling it down also means scaling down funds . The more commercial it gets , to more funds are available to make it usable and productive , in case of electricity production but also in money production . For home markets , this is how it fails. Nr1 these systems are complex ( well more complex then a boiler or air conditioner , i work chem process operator so for me this is peanuts ) , so not useful for home use . Nr 2 these systems got many potential failures , see nr 1 . Nr 3 since they are more complex , they do involve more costs in forms of initial investment and in forms of maintenance . Both are out of the question for home owners . I am all for the energy neutral or even positive homes , and yes , we can do something ( temporary , since human population keeps growing) to stop increased CO2 emissions . This however is not for home use . Do however not worry , there are new systems/batteries underway . Storing energy into heat is not for all people , it is only for company/commercial use , while it is a viable source . I however know that most people do not have all the knowledge i got , so , no heat is no resource for normal people .
  18. It requires 2 things i do not like , the TM30 and especially , the stupid flights out , which from Udon to BKK and later to Laos is just a joke . As far as i read , the TM6 is still there , so i do need to fill in official paper on how many days i stay and when my flight out is and flight number . This means a confirmed booking , which i do understand , but booking 2 flights ,Udon to BKK/DMK and then to Laos Vientiane , while i can just go by bus for shorter time and less money , just feels so stupid . Cancelling 2 flights , while just booking a hotel and then cancelling , way easier ... . Ps i i do know airline will ask my visa or onward travel plans , so i do need to show them something . They did always ask me before , and expect it not to be any different now , as it should be ( i go in a country with rules , i need to follow the rules , so 30 day visa with 52 days stay is not possible) . Personally i think i made my decision , just book a hotel for 30 days , somewhere in the middle , and cancel it later , very easy ,np ... .
  19. Im not OP , but i got similar questions . I want to go in October-November for around 55 days . Before i always took a single entry tourist visa , but the paperwork involved has gone up again . Since i am staying for most part in GF home , i do not have a hotel reservation ( needed for at least half of journey ... ) or invitation letter , including id card and house registration all Certified Copy ( were can she do that... pff ) . Anyway , the easier options are : - book hotel for half of my stay at 1 of the websites , and cancel it after i get my visa - visa run ( i think it is possible now?) or and now we get it ... Can i just enter with 30 day stamp and extend it at local immigration office ( Udon Thani ) ? Before there was the TM6 which you needed to say length of stay , and outbound flight . Since TM6 is gone (correct?) i do not need to say it . Prob the airline will ask for my visa , do i need to book a air ticket out , in the middle , which i need to scrap , so it is no problem ? Or finally get the GF doing the paperwork ( no computer in house , so will be serious hassle ) and where can she get Certified Copy ? I think the hotel option looks the most promising , easy to book and cancel and no costs involved at all , would that be a issue ? THX
  20. TBH , GMO's are not something i do like right now . I do work in chemical industry and do have a chem degree . Will GMO's do harm health ? no prob not . However , it might/will destroy habitats of a food chain . Give me a closer to nature fruit rather then a mass produced food item . Is it healthier , prob not , does it taste better , sometimes it does ( but never worse) .
  21. Checking properly? I mean that's even 1 category higher then just checking .... no way hahaha . Traffic is dangerous in Thailand , you just can try to do it yourself , and after you did check properly , check again , and then try 1st attempt while checking everything again .
  22. Yes , but we pay prob about 4 times more for electric ( per kWh used) and 2 times more for internet . Electric bill in my Western EU country now , 2 months ago new contract , +/-2000 euro ( exch rate 36 means 72000 baht) for 4000 kWh , so thats 333 kWh/m . In Thailand i pay for same amount of electric +/-1600 baht/m or 20.000 baht . Pls stop complaining ... you want premium high end everything , you will pay for premium high end . It comes with a lot of other stuff also like rules and regulations and paperwork where you do not find front or back of it all . You all now why you came to Thailand . Being a premium high end destination was not it . You could have stayed in your Western country also .There is a word which says , you pay peanuts you get monkeys ... Don't like it go back to your Western country ... I did just came back after 2.5y absence due to covid , and OMG i know again why i went there so many times before and was building something there for later .
  23. What do you mean salaries haven't increased in last 20y ? They did in Thailand and my job certainly went up by around 100% in last 20y ( taking out inflation it still is a rise ) . On topic , all food products are prone to rise in very near future , thx to grain and oil shortage involving the war in Ukraine . What does it have to do with salmon you would say ? Well , a salmon if wild caught , then the oil prices are much higher . If produced salmon then the feed for the fish is much higher . Also , for other food products , if 1 goes up in price , then alternatives need to be found, so they will rise also .
  24. Well , yes , off course , that is always something people need to consider . Getting free consumption always means , more consumption . So if you are using now 10kW per day , better start calculating at 15kW per day . For myself , i am still on my way heading there , since i need(ed) to fix some other stuff 1st .I am getting there but i am also already preparing for electric car and motorbike and complete home airco since prob that will be there . Now my transport costs in Thailand are minimal so that's no issue , but preparing for the complete home airco , i certainly need a few kW more then i would need right now . But do not let it stop you , since the energy is free for many years to come . I mean , solar is there , and yes they need to be produced , but they keep working and are very reliable . Even 30-40y old panels still produce electricity . Batteries are a different thing , but if you put out 10-20% of the budget for electric a month aside for replacing them , then you can be sure that even complete failure can be replaced without issue.
  25. Li batteries can and will go up in fire once a while . That is a fact , but everybody got several Li batteries in their home and pockets . All smartphones , computers , and similar equipment are all powered by Li ion batteries , and nobody gives a sh/t . There are also plenty of examples of cars which do/did run on gasoline , gas , diesel , which went up in fire . Some cars even got withdrawn after production because of high risk of fire in a accident .The batteries will get safer but there will always be fires because of high energy/high currents running , same like there are many fires every year in homes thx to short circuits . Can it be better , yes , but remember this . Fuel driven cars are basically end of development , same like CRT TVs were 25y ago .And like the CRT 's being replaced by plasma , lcd , led , oled , the technology is growing fast and is getting better each single year .
