Bandersnatch

I make my own electricity and save ฿5,000 a month I would have spent on gasohol

Already charging my EV from excess solar in the middle of the day.

The reason I chose 7am, 21st Dec, the winter solstice for my video was to demonstrate the tremendous advantage we have here in Thailand for solar production. Sure we suffer a little loss of efficiency due to heat, but that is far less of a factor compared to the fact the sun didn't rise in Oslo until 09:18 on 21 December 2021. As the temperature at the time was -8 degrees C, you probably had to clear the snow off the panels first.

Then you will need a Dual Axis Luna Tracker

The reality is that at ฿3,000,000 not many on this forum are likely to be buying a Tesla. I think it might be more productive to discuss EVs that expats living in Thailand are more likely to buy.

As this a Thailand Motor Discussion of EVs it would be nice if we could focus on the situation in Thailand.

I seem to remember that you are getting batteries as well, so you want maximum power production to charge the batteries. I would put you panels south facing. Regarding watering, one or two panels could power a solar pump. Did you see my video on solar irrigation?

I made this video to answer all the questions I was getting online about my solar system. I was getting lots of friendly advice telling me that I was a complete idiot by not putting all my solar on the south side of my house. Maybe it might be of interest to anyone considering going off-grid in Thailand.

1/2 mill baht buys you a 1.2 Suzuki swift. You clearly haven't see the Good Cat in person as you think that this is a valid comparison. The Good Cat is a much bigger car with far better performance (0-50 km/h takes 3.8 seconds) Far better spec'd (see the pics I posted above) It will also will be far cheaper to run: the 47.8 kWh battery gives a 401 km of range and using the overnight TOU rate will cost 126 baht for 401km Suzuki swift 20.0km/L @ 31.58/L would cost 633 Baht for 401km

I agree with @macahoom this bogan is unwatchable, so I'm not fact checking any more of his videos - bias assumed and move on

My mechanical room is insulated - AAC blocks, white steel roof with foil and foam insulation with a 50 inch ceiling fan. I don't plan to use aircon as I want to keep the room well ventilated, but I am planning to revisit geothermal.

I agree it does seem very short. My LiFePO batteries have a much longer claimed life. I do not know what batteries were tested in the study or even when the study was done, but my take away is DOD does have effect on cycle life, so I am planning to over spec my storage accordingly. https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries

DOD will effect the life of a lithium battery (See Table below from Battery university)

Thanks, but I can take no credit for it as I employed a professional http://www.h2owatersystems.co.th/ Ruben from H2O water systems tested my well water but his recommendation for drinking water was rain water. So I have 2 filter systems: one for household water and one for drinking water.

Great Wall Motors' Ora Good Cat came to visit Robinson Surin yesterday. 48kWh Lithium Iron Phosphate Battery 400km range ฿989,000 https://www.gwm.co.th/ora-good-cat/ I know it's a little thing, but I like the fact that the phone charging pad is positioned very centrally so that you can clearly see the phone.

Hi Jake I have 3 x Growatt SPF 5000 ES - 5 kW inverters one would suit your needs. I run it off-grid with a grid connection for backup. Unfortunately panels are 2mx1m = 2 sqm per panel, so you have only room for 6. The 500+ Watt panels are even bigger. What else would you need: brackets and rails for your roof; solar cable extensions; breakers etc. I have batteries and they are extensive. One option is to use the battery as a big UPS for a separate circuit for your house for low power items during a power cut. I have 3 nRuit 9Kw LiFePO4 they cost me ฿68,000 each My system :

A peer reviewed study published in a scientific journal makes me think. A story about a talking battery might make a first grader think - clearly the intended audience.

Part of the reason for doing the video was to have a record of what it once looked like

Life is a DIY project - love this thread. Before embarking on my latest solar upgrade I decided to convert my mechanical room into a workshop. I admit to borrowing some ideas from a fellow expat.

In addition to using solar to power my house and my car I am also using solar to aerate my pond and run my drip irrigation system in my garden

My land is about the same size Firstly I would say my expertise is more on the solar side than the gardening side. I have installed 4 solar pumps in Thailand so far - 2 I installed myself and 2 I outsourced. My first solar pump was for my house build. "Builder said they can start on Monday but they need water" I bought the well pump and solar panel from the same shop in the next province, but had to make the panel frame myself and do the install Cost about ฿20,000 I then did a surface pump install at my local primary school - taking water from a pond to water plants. This was a smaller system and cost about ฿10,000 I outsourced 2 on my land, the smaller one featured in the video cost ฿20,000 plus ฿6,000 to drill the well. The bigger one was about ฿50,000 all in. The pipes and connectors are not expensive and we installed them over a period of 3 years so I couldn't tell you the total cost, but a trip to Thaiwatsadu, HomePro, Global House, etc you would you would be able find the cost for your situation. The bigger solar well pump is also a backup for the house water system as we off-grid for water and so is oversized. My installer here in Surin provided the pump and panels you can contact him @ http://www.8urich.com I have used both a spray system and a drip system - The spray system uses much much more water and as it over-sprays it tends to encourage weed growth. The drip system just puts water just at the plants, but I agree it is more work to setup up and maintain.

You are correct

Not sure where to post this. I bet that the guys over in the Renewable Energy Forum will not be interested in my garden, but I am not sure how many people here are interested in using solar. Anyway, here is a video of my Solar Powered Drip Irrigation system with a tour of it in operation in my garden in Surin

The last time I looked at the Solar rooftop scheme (feed-in tariff) If you had a single phase connection then the maximum PV was 5kW. This rose 10kW if you had 3 Phase. I assume it something to do with the capacity of connection you have to the grid to feed back. I have 20kW on a single phase so no feed-in tariff for me - no problem I just dump my excess solar production into my house batteries and my EV
