I disagree with the placement of his panels, I think he could get more out of them by not putting any on the north facing side but the rest was very impressive.

I explained in detail in my blog why I chose to put solar on all 4 sides of my house. See https://ecohousethailand.com/design-criteria/

Dual Axis Tracker systems can increase production by 40%, but such systems are complex and expensive and with falling solar panel prices it is cheaper to just get more panels.

Basically I don't need more power, but I need to extend the hours when the solar is producing and so reducing the hours that the house is running off batteries.  Living close to the equator as we do, North facing panels produce power for much of the day, but more crucially, they are producing at the beginning and end of the day. I am getting power at 6am. 

Unfortunately I do not have stats to share currently as there is a problem with the external data module that came with the inverter.

Do you use a centrifigul blower for that?, they give a very high air output, against reasonable electricity costs. But in my experience they heat the output air easy to 80-90 degrees. We used them to dry metal sheets after processing. First we thought about the need of installing heaters. But heaters where not needed. The output air is close enough to the temp from boiling water. Together with the enormous airflow, everything is dried. 

I have not dissembled the Energy Recovery Ventilator, so cannot comment on it's fan. We did test the ERV before piping it is and it did not heat the air. To be honest we do not use it very often. It part of the future proofing of the house. The door to the third floor acts like a chimney drawing hot air up and out of the house. The wind on the third floor always blows due to the venturi effect helping with the efficiency of the chimney.

Do you guys refrigerate the batteries?

I designed my house from the ground up to be Off-Grid. I have a dedicated mechanical room which is insulated and well ventilated. I installed a large DC motor ceiling fan. The purpose built battery rack allows lots of air flow. I have not seen any drop in battery performance over the last 12 month.

I hope that your batteries last ten years. I also had deep Cycle Gel batteries. 20 pieces 100Ah The last around 5 years. I have ordered now LiFePo4 bateries. 16 pieces 3.6V280Ah. According the specs they should give at at least 5.000 cycles.

The depth of discharge has a great deal to do with battery life. My Hybrid Inverter is set to draw from the grid when the batteries reach 50% state of charge. I usually have about 60% when they start charging again at 6am

The big ticket items on my solar system:

Solar panels Monocrystalline 350W X32 = 11.2kW ฿3,500 each = ฿112,000

Deep Cycle Gel Batteries 12V 200AH X 16 = 38.4kWH with cable and rack ฿13,250 each =  ฿212,000

Off Hybrid Grid  Inverter Power: 10,000W = ฿96,000

My electricity bills are zero  - payback is about 10 years (assuming prices don't rise -which they will) or 10% - try getting that these days. I also enjoy having power when the lights go out in the village.

This is not required for Committee members except if they are paid

Committee members generally don't get paid. I don't know any in Pattaya that do. They do however give up a great deal of their time to try and solve the problems of their building. It is without doubt a thankless task  - In 4 year as a committee member I never once was thanked for my work, however I had to regularly suffer the anger of residents who thought we had a magic wand to fix all problems. Fixing a problem like restricting non residents from entering a condo is just such a problem. Don't expect security staff on minimum wage to deal with it. Better to invest in expensive security systems that make it difficult for non residence to wander in without a key car or access any floor in the lift like some hotels do.

I would never be on a committee again having been sued twice in 4 years both completely baseless and thrown out by the court but only after a great deal of stress and unpleasantness.

Suspension of the water from Provincial Waterworks Authority Pattaya / ประกาศแจ้งตารางการจ่ายน้ำประปาจากการประปาส่วนภูมิภาค พัทยา

Dear:  Co-Owners / Residents,

The Building management would like to inform that Provincial Water Authority had announced temporary shortages in water supply all over Pattaya. The Provincial Waterworks Authority, Pattaya branch, has announced the water distribution schedule for April 2020

Back on topic.....what is the likelihood of a full lockdown?

Thanks brewster for bringing this back on topic. Where I am living they are introducing a curfew from 20:00, with checkpoints running during the day as well. It would not take much to extend that.

As the OP stated: He is "concerned, living in Thailand through this period of uncertainty"  It is unfortunately probably too late to prepare for these uncertain times, but maybe when this all blows over people will have a slightly different attitude to being prepared.  

The OP asks "Will there be a rise in crime"?  When money is short, it is inevitable. Too often I have seen comments on this forum like "I have never locked my door in 30 years - never had a problem"

From US Department of Homeland Security - Federal Emergency Management Agency:

This is what the checkpoints look like now - not very intimidating, but that can change.

Hi Crossy,

This is the PU foam I used on my Thai build, which is waterproof and sets hard

Another reason for driving an electric car is the environment and before you all start saying that electric cars are coal powered...

Electricity Generation by Fuel, in Thailand 2018 (Terawatt-hours)
Oil                  0.2   

Natural Gas  116.3  

Coal              35.8

Nuclear           0 

Hydro             7.6 

Renewables    17.8

Total             177.6

https://en.wikipedia.org/wiki/Energy_in_Thailand

The capacity of non-hydro renewables may expand to 21% of Thailand’s total power capacity mix by 2028

An electric car has got to be less polluting that what we see on the roads here in Thailand

I think most people who have an EV probably have a home charger and would do most of their charging at home at off peak rates. The MG EV I looked at buying recently here in Thailand came with a free installed home charger. 

If however, you live in Europe, do not have a home charger, and can only use Ionity chargers, then as the article above suggests  you would be better off signing up for a contract and paying €0.33 per kWh instead of €0.79 per kWh. Nobody would do all their charging at €0.79 per kWh.

EU company just raised their charging fee

IONITY has increased it's price from €8 per session to €0.79 per kWh without a contract or €17.95 per month and €0.33 per kWh with a contract, just as well that there are no IONITY  chargers in Thailand.

Below are some pictures that I took at my local Robinson here in Surin. A 22kw type 2 charger would add approximately 120km of range per hour of charging.

But you solar panels at home did not come for free, you had to buy and install them, plus if you have a battery back up that had to be paid for as well. The batteries and solar cells will need to be replaced periodically. It might be a relatively low cost to run a solar cell system but the start up costs will be fairly high and even more so if you have to but an EV as well.

 

The last time I checked on a solar cell system it came to about 7 years of electricity bills upfront money.

I won't argue with you on this, but everyone's situation is different. For me, I have savings and investments that produce an income that I live off in retirement. With interest rates in the toilet, it makes more sense for me to reduce my future costs, rather than try to increase my income. I would have to invest ฿2million at 2% to cover my current electric bill and as electricity costs rise so would the amount I would have to have invested. 

I have excess solar during the middle of the hours of the day (my batteries are fully charged by 10am), which basically means free fuel for an electric car. So when comparing the cost of an EV or an ICE,  I would have to add the cost of the fuel I would use with the ICE. 

I don't currently own an EV. I nearly bought one when I installed my solar, but decided to wait to see if we get more choice of EVs in Thailand.

The map looks great until you go to the app and look for charging stations outside of the big cities and even along the main highways there isn't so much

Sounds like you do a lot of long distance driving, so probably an EV is not going to be right for you as an only car until you they build more charging stations, which is what this thread is about "charging-stations-to-be-set-up-at-50-70km-intervals".

I on the other hand would be charging at home for free from my solar panels and driving less than 200km round trips.

Once you have rooftop solar, having an EV is the next logical step. I am producing more power than I can use or store and would love to dump it into an EV. Most of my driving is local, so my next car will definitely be an EV.

Number of Telsa Supercharge stations in Thailand zero

Tesla Supercharger Stations use a proprietary plug that means rival electric car brands can’t use them

Only in the US. In Europe and more importantly for us here in Thailand, Chinese built Teslas, will be able to use the regular charging stations.

May I ask please where you got the air quality monitor?

There are cheaper ones if you just wanted air quality checking for PM2.5 but I wanted the CO2 as well.

I also live in Surin and the burning season seems to have just started near me.

I monitor the pollution levels and they seem worse in the mornings until about 10am after some sneaky night time burning.

I have a HEPA air filter running in the bedroom at night. I also have a whole house air filtration that I can run if I want to lock the house down tight.

I have recently finished building a house here in Thailand. Tiles were one of the last things that we fitted and we changed our minds several times about what tiles we wanted where and even what we wanted tiling.

I actually thought that tiles in HomePro and ThaiWatsadu are pretty reasonably priced and they can deliver them to your house. I wouldn't have wanted to deal with arranging shipment from China and import duties. We were also able to buy extra tiles as we needed them. 

We built with foam filled cavity wall with wide overhangs to shade the walls.

Could you kindly elaborate on ERV's.

I installed an energy recovery ventilator when I built my home here recently. You can read more about it in my blog https://ecohousethailand.wordpress.com

The inter core of my building is a conditioned space, with windows that are sealed shut and doors with 4 frames and airtight seals around the top, bottom and sides. On the ground floor this includes the living room, office and master bedroom. On the second floor this includes the second bedroom, cinema and gym.  

So it is important to bring fresh air in and take stale air out. The fresh air is cooled by outgoing air-conditioned air, then filtered. Incoming humid air passes humidity to the dry expelled air. Filtered air is pumped into each of the rooms with one extraction per floor. 

The ERV will cool incoming air, filter it and reduce its moisture content.

I can recommend Ruben from H2O water systems in Buriram, he helped me me with my water system, which started with testing

And how much did you spend for this rig?

Difficult to give a price for the just filters as it was part of a whole house water system including the rainwater harvesting system.
