Testing Solar Devices

Our solar powered DC fans are making a lot of wind!
We can let them run on 12 Voltage with amazing low 11 Watt consumption.
For very large rooms and heigh ceilings we recommand a 24 Volt system with double of cool air and still low 50 Watt consumption. Next week we will test a new DC dimmer, this will control both speed and consumption.
Our solar powered LORENTZ DC pump for swimming pools is working as strong as promised on the specification. Here we can add a "AC power pack" that enables the pump to be supplied by a gemset or standard grid power for cloudy periods (fully automaticly) or for higher filtration need:

Limited testing facilities? No way, there is always a way out in Thailand!

Water purification

We are now promoting "water purification" systems:
Our german managed new partner in Laos Ourworld is producing water purification units from small scale to big scale - depending on the needs of the customers. Ín short words, those systems consists of a filtration station followed by an OSRAM UVC lamp - Ourworld is exclusive distributor for thise OSRAM products.
The purifiers are not only suitabel for drinking water supply but they are - and thats more interesting for Koh Samui - a very effective swimming pool purifier. Here your benefits:
> Protection against germs and viruses, reduced formation of mold, bacteria and algae
> About 90 % reduction of chlorine additives and other chemicals in swimming pools
> No smell of chlorine, no skin and eye irritation
> Environmentally friendlier than conventional methods

Those OSRAM systems are available wordwide. As they use a very small amount of energy, they can run or on public grid or on a small solar panel.

We are happy to provide further information concerning the whole concept of water cycle as your requirement.

Energy Consulting

Energy consulting is not an easy job. It consist of different topics:
- Energy basics - why is cheap green tint glass better than high tech "E-glass"?
- Energy believes - to convince that even in Thailand you can survive without air conditioner.
- Energy savings - why you should pay 300 USD for a ceiling fan and 800 USD for a small fridge?
- Energy systems - how to mix different energy sources (grid/solar/gemset...) in a smart way.
- Reduce your energy load - invest less money for reneweable energy
- Finally: Choose the best quality solar devices

More about these topics can be downloaded here:

ENERGY CONSULTING

You suffer from regulary power outages? We can offer you a reliable backup system to supply your connected loads with the desired power. Two components: A Made in Switzerland system controller from STUDER and our AGM batteries. The STUDER is connected to your fuses box and controls your energy supply. When a power cut occurs it will switch to battery supply in as little as 20-40 milliseconds. Thus it can even work as a powerful USP for hours for your small office or for a larger server room - keep in mind that a standard USP lasts as short as 30 minutes. We design the battery size according to your need - how many devices must be connected for how many hours.
The STUDER is a pure sinus inverter - the DC power from your batteries is transformed to real AC power and can supply every electric device. Depending on the model it can handle between 1 kWh and 8kWh. Surge power of your water pump or your fridge & freezer? No problem, the STUDER can handle up to 250 % of the nominal power! When grid power is back the STUDER switches back and starts reloading the batteries. In addition the STUDER can also start a diesel engine and can charge the batteries with clean solar energy.

LORENTZ Etracker in action

Solar powered DC pumps are the most economical solar applications - they need no batteries. Whereever you have no grid on site a LORENTZ solar pump "Made in Germany" is the best choice to pump water directly to a pond or to a storage tank. To rise the pumped water volume Lorentz is offering a one axis tracking system (see pics from our customer). What is behind:
A solar tracker is mounted under the solar array and follows the sun during the daytime. According to our customer the pump volume has risen about 40 %. A LORENTZ etracker is a good investment!

Solar Water Heater versus Heat Pumps

For Hotels a Heat Pump is a good choice to produce hot water. Heat Pumps from reputated manufacteurs like Stiebel Eltron (see here) are reliable and about three times more effective than the conventionel electric heaters. But is a Heat Pump a better choice than a Solar System? Let me give you an example:
For a hotel building with 30 bedrooms and a lot of bathtubs you will have to install at maximum a 3.000 liter hot water system (50 liters per guest and day in case of 100 % occupancy).
- A Stiebel Eltron system costs with installation around 600.000 THB.
- Our Heat Pipe system (see here) costs also 600.000 THB.
Both with a well insulated tank, controller unit, 3-way-mixer-valve, installation - both systems are "state of the art"!
Stiebel Eltron gives 3 years warranty on the Heat Pump, we give 5 years warranty on the whole system.
Now compare the running costs - let us make some quick and dirty calculations:
- Occupancy rate in average 70 % means around 2.000 l of warm water at 60 °C per day.
- With cold water at 25 °C you need 81 kWh per day - remember: 1,16 Wh to heat one liter of water by 1 °C.
- A Stiebel Eltron system might have a total COP of 4.0 - thus 20 kWh of energy is needed
- Running cost for electricity per year are 30.000 THB with grid power (4 THB/kWh) and 150.000 THB with a diesel generator (20 THB/kWh).
- The running costs of our solar system are maybe 2.000 THB (grid power) and 10.000 THB (diesel generator) per year.

Conclusion:
The investment is the same, our warranty is longer and: Be aware of the running costs!

Reference list for commercial Solar Water Heater Installations

After the first good experiences with small installations (we sold 16 Solar Water Heaters so far) we are now focusing on the commercial and industrial market. Solar Water Heaters are not yet a success story in Thailand. Sunlabob and Samui Service Solarpower are trying to change this. Here a reference list of commercial installations from the last couple of years:

Samui Service Solarpower is not a sales shop. An example of our quotations with engineering and financial calculations can be downloaded here. You will be surprised that solar energy is a comprehensible topic.

Hot water for Anantara Resort

Here one of our three Solar Water Heaters for the elephant camp at the amazing 5-star Anantara Resort, Golden Triangle.
Because we sent them a manual they could handle to install it by themselves. Nevertheless, Samui Service went on site to check the installation:
As the Anantara engineer team didnt believe that water would be "so hot" they didnt install a water mixer to chill the 65°C solar water by cold water. Well, the water scalded a mahout yesterday, now they trust the system!

The Anantara Resort wants us to quote two more Solar Water Heater (SWH) Systems:

- From november until march it is getting very cold in the North of Thailand! To save money and energy, we will design a SWH system for their 400 m³ infintiy pool - we will have to prove that Solar is cheaper and better than gas fired oven or heat pumps. We will setup a system that can substitute part of the hot water supply for the 84 rooms as well.
- The second quotation will be for the now gas fired laundry section.

By the way: The pool is wonderful!

Pay-Back-Calculations

" Our engineer in Bangkok has calculated a pay-back period of 1 or 2 years"

To avoid confusion and dumb or false statements here the calculation:

- To heat 1 liter of water you need 1,16 Wh per Kelvin (K)
- "Wh" means Watt-hour: 1000 Wh = 1 kWh, the common unit on your electricity bill
- So you need 1 kWh to heat 30 liter of water from 20 °C to 50 °C (30 K)
- If your cold water has 20 °C and you want to have a shower at 35 °C using 60 liter of water:
- You must heat 60 liter of water from 20 °C to 35 °C

How much energy you need? Yes, you need 1 kWh! If you want to supply 4 peoples? Yes, 4 kWh
How much energy per year: 365 * 4 = 1.460 kWh
One kWh costs you 3,5 THB (not 5 or 10 or 12 THB!)

Conclusion:
4 people uses 5.110 THB per year to have a warm shower every day.

If you pay 20.000 THB for your Solar Water Heater, the pay-back period is 4 years.
If you pay 50.000 THB for your Solar Water Heater, the pay-back period is 10 years.

Don't let you fool from a Bangkok based engineer!

Solar Heater Installation with "solar solutions"

Together with our partner we have installed a flat collector with tank in a private villa near Pattaya.
The collector will provide warm water for the shower (3 peoples), for the kitchen and for the washing maschine. A flat collector with an heat exchanger and with an temperature controlled circulation pump is normally a bit oversized for a private household. But the german landlord wanted to have a state-of-the-art "high-tech-system".
