  1. It's all about MONEY, a 30 day pass (visa) the Thai's do not get paid. Is it not better that someone has a 30 day pass (visa) than nothing. A 30 day pass is still a visa to stop in Thailand for 30 days, call it what you want.

    OK now lets say anyone that has one FREE 30 day pass (visa) has to pay a FEE off 300 baht each time there after then the Thai's would be making something, Problem sorted.

  2. Cheap panels can burn out,

    Ouch!!

    Many people look at price first and with solar you can not do that, We have been called out to 5 or 6 jobs that other company's have done and had to redo the full setup. One case the customer told the solar installer what they wanted instead off the installer telling her it can not work that way, he just did as she said, A 5kw 3 phase grid tie with 6 x 280w panels on one line and 7 x 280w on another line. the voltage was under for the MPPT to start on the 6 line and the 7 line was only 1 volt over. I told her if she had asked us to install it like this I would have walked away.

    Can I also point out that I do not know the company that has installed this set up in this post and do not want to scare the new owner BUT wish him all the best with his new solar set up. More people should be doing the same and installing solar.

  3. Cheap panels can burn out,

    What's the backstory on this photo though?

    For all we know, the installer may have wired the system to exceed the max. series voltage of the panels.. or a hot cinder could have landed on them.. or they could be junk panels smile.png

    A photo like this only raises questions, not answers tongue.png

    Yes a photo like this should be asking questions BUT we do not know the full fact off why BUT I would say it is down to the installer, installing to many panels in series, BUT what we also got to ask is why did the panel not fuse at the max out put voltage. Which is what they are designed to do. Hence the short circuit voltage.

  5. Well just finished the top row of 10 panels, they'll be finishing the bottom row of 10 after lunch. Currently wiring the distribution and inverter boxes.

    Is it an optical illusion, or is the spacing between the upper pair of mounting rails different from the spacing of the lower pair?

    No it is not an optical illusion, count the tiles between each. For me the over hang on the top row is not good and should off been moved to be inline with the bottom row.

  6. what's the estimated total cost and the total m² of the panels?

    Panel area 30m2 (20 panels @1.5mx1m)

    Total cost inc mounting kit and installation ฿256K

    The price will depend on the standard off the panels and Grid Tie. The weight off the panels will give you an idea to the quality as the weight is in the frame and glass used. We use 300w panels a lot there are many kinds BUT to give you an idea one panel weight is 28kg and another is only 22kg. NOW I have had some people say BUT that is good as not as much weight on my roof, Wrong you are fitting solar that needs to last for 25 years or more. Cheap panels can burn out,

  7. If your meter is changed to a digital meter, you will not be able to turn your meter back for night time. Only if you have 2 meters one that you are using electric from and the other digital meter feeding the grid supply from the solar BUT then if you have this you will be on the rooftop program. The paper work can take months to come back from the PEA. If you turn back your rotary meter to less than what was on your last bill reading, they will send you and estimated bill from your last 6 months worth off bills. Until you have all paper work in-place make sure each month you do not go under your last reading or they will charge you.

  8. IMHO, thanks for posting that I was just about to post the same chart. I'm in a deep red area just south of Khon Kaen. Completely unshaded, direct south facing roof installation, so it's just about as good an install as possible.

    First panels are about to be mounted, I'll post some pics as soon s it starts

    I would like to see the spec on these 250w panels.

  9. Inverter & Breaker boxes being wired up.

    having a little pause outside, 4 more panels to mount, but....hasn't rained for frikkin weeks and it decides to p*ss it down this afternoon

    I hope they bring a ruler next time to get the conduit holes lined up. Such a little thing and so easy to get right ...

    I would be rejecting that.

    Is the inverter IP rated for outdoor installation, if we go with this it will be on the wall next to the car-port.

    Yes this Grid Tie is IP65, Here is the spec on this Grid Tie. http://www.positronicsolar.com/uploads/Trannergy_Brochure.pdf

  10. The law predates the Junta

    There is a law against disclosing a police checkpoint that is out in public view? Can you provide the citation for that law?

    I think the violation comes under the law of "Whatever Suits the Police."

    There is no law, it is an act that is in place, An act is not law only a contract between 2 party's, Act's and statues are nothing more than a contract, if one does not agree then there is no contract.

  11. The JSI Grid Tie is from JFY and these are not on the approved list for the PEA BUT they are cheaper than the grid ties that are, so be careful. Most places charge between 12 to 15 baht per watt to install. So a 280w panel will cost you another 4,200 baht to be installed. @ 15 baht per watt. The Globatt batteries we used to sell BUT have had to many problems with them and have now gone over to Bellco. Heat can be a problem, always leave a 1cm gap around the panels and at least 6 to 8 inch from the roof to allow max air flow. The angle we find the best is to have between 12 to 14 inch over a 2 meter long panel which is what the 280 and 300w panels are, or just under. One 280w panel will take your bill down around 200 baht per month so if your bill is an average off 2,000 baht you will need 10 x 280w panels and a 3kw Grid Tie. BUT always remember you have to marry the panels to the Grid Tie and the Grid Tie to the panels or it will not work at its max.

  12. Sorry, to answer your question;

    Based on unit price per kW @ 4.5 BHT and your monthly bill BHT4,500 this equates to a monthly power demand of about 1000 kW or on a daily basis around 30kW (1000/30). This is less than earlier respondent.

    Power ratings of PV panels are based on kWhr, so a 10 kWhr array if producing this power over 5 hrs sunshine should exceed your required daily demand. However, even considering variability in the weather and fluctuating demands, it can be seen that a 10kW array may be larger than your needs. The only real way of showing this is from meter readings after installation, so ask for references from other installations. Remember, it is in the engineers interest to over-sell their products to maximise profits.

    Here in Thailand we work on a 5.5 system,, so for 1kw of solar will give you 5.5kw on average per day,,, AVERAGE,,, some time more some times less,,, BUT you have to think when it is less you use less electric,,,, So a 30 kw used per day would mean you would need a 5.5kw system,,, We have customers that have to turn on the air con just to use the power they are making,,, Its a 6 to 7 year payback time,,, NOT 10 to 15 as someone said,,, The price off solar has dropped 60% over the last 4 years,,,,
