LARGE BACKUP SOLUTIONS

What is a solar home system like described below without solar panels and without solar charger? It is a smart setup for "uninterrupted power supply" - an UPS. Our Victron Multiplus devices are not only battery charger and inverter but on top of this they act as a very fast transfer system: In case of a power cut, they switch in not more than 40 mS to the battery backup. So if you need an uninterrupted power supply for your office or for your residence - regardless 1-phase or 3-phases power - our large UPS-solutions are an economical choice and -while maintenance free- a real alternative to diesel generators powered backup.

SOLAR HOME SYSTEM

We have installed the first solar home system in Koh Samui. It will supply the energy for a 2 bedroom house with swimming pool. The whole project costs were less than the fees to get a connection to the public grid. For remote areas these kind of solar systems are an economical option - but be aware that it is still not possible to supply air conditioners. Beside of that it is a must to invest in low energy devices for lighting and for pumping. Click on the thumbs to enlarge:

Solar Array 4 kWp	Battery bank 48 VDC deep cycle 36 kWh	Solar charger 80 Amp and AC inverter 4 kW	Solar water heater with 200 l tank

COST SAVING FOR THE "FOUR SEASONS"

The Four Seasons in Chiang Mai has a large laundry section with a hot water consumption of approximatly 5 cbm per day. To reduce the running cost for the gas fired boilers Samui Service has installed a waste heat recovery for the very large air conditioner. The hot water is stored in two 500 l pressurized tanks. We estimate that this system will provide around 2,500 kWh cost free thermal energy per month which is equivalent to 250 kg gas. Click on the thumbs to enlarge:

WIND ENERGY ON KOH SAMUI

Samui Service has installed the first wind turbine on Koh Samui. The Whisper 200 is standing on top of the Samui mountains at an altitude of 621 meters. Thailand is not at all a "wind country" but we are pretty sure that this is by far the best location on Koh Samui for a wind turbine. Together with a small solar array the Whisper 200 will provide enough energy to supply one restaurant and to illuminate a buddhist temple on top of Koh Samui. It should be mentionned that already this rather small wind turbine must be erected at least 20 meters away from the nearest building - noise is really an issue. Hence we have installed controller, batteries and AC inverter into an adjointed building with small AC wires going to the supply points.
This project together with the new temple is donated by Khun Voravuto, a Thai citizen and Bangkok resident. We say thank you.
Please click here to see a MP4 with the spinning turbine.

LOW ENERGY POOL PUMP - HOW IT WORKS

Swimming pool pumps are consumpting 10-20 % of the total energy need of a standard Villa in Thailand.
This is not necessary. To reduce the energy consumption just install a smarter pool pump.
Now look here, this american pool technician is explaining "how it works":

We are promoting this "Pentair IntelliFlo Pool Pump", because
> it saves a lot of energy and money
> it has a more effiicent motor than the standard pumps
> it offers many features like built-in controller, LCD display, spa functions, backwash alarm etc.
> there are so many swimming pools in Thailand!

Europeans are not used to "gallones per minute" "GPM" and "pound per square inch" "PSI". We like "cbm per hour" (cbm/h) and "bar" :
> 1 Gallone = 3,79 liter. Hence 80 GPM = 18,2 cbm/h.
For a medium size pool with 80 cbm volume it is enough to run a pump with 80 GPM for 8 hours a day
> 13 PSI = 0,9 bar or 9 meters water column
Last but not least: The enery price in USA is 100 % higher than in Thailand.

The physics behind are rather easy (this is now a bit simplified, we not consider the static head...):
Friction losses in a piping system are proportional to the square of the velocity of the pumped water. While velocity is proportional to the discharge of the pump: If dischage is bisected (like from 80 GPM to 40 GPM) then the friction losses are reduced to 25 %, the pump needs only 25 % of the energy and not 50 %. In other words:

> A pump that can discharge 80 GPM at 2 kW will need only 1,1 kW to discharge 60 GPM
> A pump that can discharge 80 GPM at 2 kW will need only 500 W to discharge 40 GPM
The Pentair IntelliFlo uses even only 290 W because the motor is more efficient at lower speed.

What does this mean for your electricity costs per year (EC):
Standard pump 2 kW, 80 GPM, 8 hours per day:
EC = 365 days/year x 2 kW x 3 THB/kWh x 8 hours/day = 17,520 THB per year
Pentair IntelliFlo pump maximum 3 HP, running at 290 W, 40 GPM, 16 hours per day:
EC = 365 days/year x 0,29 kW x 3 THB/kWh x 16 hours/day = 5,081 THB per year

Savings are 12,500 THB per year which allows a pay back after 1-2 years (compared to standard pool pump).
Regarding the CO2 emission the energy saving of 4,000 kWh equals more then 3,000 kg CO2 gas emission.

Be smart, be green and save money!

DRINKING WATER MADE BY GERMAN TECHNOLOGY

We are now dealer for PURION GERMANY water disinfection systems. This will allow us to "sell drinking water"!
Purion uses UV radiation to destroy the DNA of bacterias. This technology is a lot cheaper than Reverse Osmose and it is 100 % chlorine free.
UV radiation is applied worldwide to supply drinking water, regardless if the source is well water or lake water. As it is a low energy technique we can supply the systems with solar energy.

If you have problems with the water quality, contact us, we can provide drinking water at every tab of your house.
Click here to understand the operating principle and here for specifications of the purifiers.

Of course we also provide tank ozonisation and filter stations. And we consult before we sell!

3-PHASE SOLAR POWERED SUBMERSIBLE PUMP

Now solar pumping is available even for very large water demands up to 500 cbm per day: Lorentz Germany has developped new solar powered 3-phase submersible pumps with 10 or 15 HP. Click here for specification.

The PS9k is connected to 9 kWp solar array while the more powerful PS15k needs 15 kWp to operate at maximum power. For non-tracked operation we advise to install 12 kWp / 20 kWp solar array.
The pump controller offers a lot new features like
> two control inputs for well probe (dry running protection), float or pressure switches, remote control etc.
> automatic reset 20 minutes after well probe turns pump off
> data logger for historical dates: running time, starting/shut down time, max. power/voltage, accumulated energy etc.
> display of current running data such as: input/output current/power/voltage, pump speed, temperature
> speed control selectable, max. and min. speed
> solar operation: integrated MPPT (Maximum Power Point Tracking)

LOW ENERGY LIGHTING SOLUTIONS

No 50W halogen spot lights! No 100W incandescent bulb!
We it comes to interior lighting LED are already the best solution. With RGB LED you can choose and change between many different colours and many nice features including dimming and fading. LED are the most elegant way to create an interesting atmosphere! Power consumption is only 5 W per meter. We have combined these LED with very bright CFL bulbs 15 W, dimmable as well. Click on the thumbs to enlarge!

"LED are expensive!" No, the whole lighting costs for this project were only 1 % of the total budget.

AIR CONDITIONERS AND HOT WATER

The first installation jobs with Air conditioning and Hot Water have been completed succesfully:

For these newly renovated bungalows we have installed the hot water tanks where the water is getting heated directly by the refrigerant pipe. We use stainless steel tanks and heat exchangers, no risk of corrosion - these systems are running fine since ten years!

Retroffiting of the waste heat recovery system:
The heat exchanger is behind the compressor, the warm water is transfered to the tank by PPR pipes. Besides of the storage tank this system needs a circulation pump and magnetic relays:

TESTING WASTE HEAT RECOVERY

Our new branch is getting cooled by an 24,000 BTU air conditioner with waste heat recovery:
The thermal heat in the refrigerant gas - normally blown out by the compressor fan - is transfered to a water filled circulation pipe which is connected to a hot water storage tank. For several days we have monitored both the energy consumption of the A/C and the hot water generation:

- It takes 6 hours to heat up 300 liters water from 31°C to 45°C, this is enough for 10 warm showers and it is equal to 5 kWh
- In average the A/C is consumpting 1,6 kW per hour, hence almost 10 kWh in these 6 hours
- This means that 50 % of the electrical energy to run the A/C is normally wasted - blown in the air by the compressor fan.
- The yearly costs saving by running 6 hours is more than 6,000 THB - not regarding the saved investment for several electric water heaters.

Regarding your electricity bill:
The standard hotel business is charged also according to the maximum demand in 15 minutes, see here, page 6.
This "demand charge" means for example:
- For 10 electric heaters each 5 kW running at the same time for 15 minutes the "demand charge" on your bill will be 10,000 THB per month higher! Avoid electric heaters but use your air conditioner to provide hot water.

Be smart, be green and save money!

THE LARGEST PRIVATE SOLAR INSTALLATION IN THAILAND

After coordinating three specialised teams and up to 12 staff members, after installing 250 m² of solar panels,
8 tons of batteries and more than 2 km of cables:
The largest private solar installation in Thailand is providing 80 kWh of 3-phase energy and 20 m³ of fresh water per day.
Beside of this we have supervised the whole water feder system, assisted to establish a smart irrigation system and finally
low energy intelligent pool pumps and a modern water purification system.
Everything is working fine but of course they are still some problems or concerns about the established new technologies,
hence we now focus to the "after sale service", means we are still on site every week for training (and learning!) purposes
and to check which parts of the systems might better be upgrated. A very exciting project is becoming succesfull and it will
be our showroom for similar scopes.
Here some impressions, please click the pics to enlarge.

The project has the size of an hotel with different buildings	Located on the beach without road access!	Coordination is a basic duty but not easy in Thailand.
Voilà 126 solar panels	Rough conditions close to the sea - hot and dangerous	The SMA inverters are creating a pure 3-phases AC grid.
Six Sunny Islands on the way to their destination.	We control the performance by the grey colored webbox.	We have designed and installed some very special features.
Setup of 8 tons of batteries providing..	... total 200 kWh energy. Enough for 3 days supply.	The small diesel backup will start automaticly on very high load.
The solar tracker is supplying 4 DC solar pumps	Installation jobs can be wet and funny.	We will now monitor the water supply and demand - to learn more.
The 250 m³ pool would normally use of 60 kWh pump energy	Our smart pumps can reduce this to only 20 kWh per day!	Where to buy or order the specific device? Difficult every day!
Drinking water by an UV lamp with filtration	Low energy solar fridge and freezer - saving up to 70 %	My teams: Keen to learn, carefully and always in good mood!

AIR-TO-WATER HEAT PUMP WATER HEATER

This is definetly an cost effective alternative to solar water heaters,
especially if the property will not be occupied every day of the year.
Low energy consumption and the cooling capacity makes it a "green product".

SOLAR LAUNDRY HEATER

Twelve heat pipe collectors and one 1000 liters Solar tank will help the Anantara Golden Triangle to reduce the extremly high gas costs at the laundry section. Definetly a useful application for Solar because the thermal energy is produced "on demand" means from 8 am to 5 pm when the large laundry machines are running. Considering that the Anatara is located some 1,600 km away from Samui and that we had to ship a lot of equipment for this large installation we are pretty proud that we could complete this demanding job in a succesfull way. Thanks to the Anantara team for their support!
