Why Solar? Because electricity prices will keep on rising…
Headline April 2012 Over 400 units per month a Thai household pays 4,2 Baht per unit. Industrial users may pay up to 5 Baht and peak time charging might come in the future through smart meter and smart grid initiative. Thailand local gas resources have reached peak gas production. From 2014 on it will decline. Thailand will rely increasingly on expensive gas imports.

And so does the consumption per capita Households with consumption of 10.000 units per year are not rare but the rule in well equipped households
*Data from Index Mundi 2012

Question:
Knowing all of this – what do you beleive could be the price of electricity in
• 10 Years? • 20 Years??
• 6,7 Bath / Unit • 9,0 Bath / Unit (current price in Germany)
Now: how does solar compare to that?
06.06.2012
Solar Cost LCOE = Levelized Cost of Electricity
LCOE over lifetime of 25 years a solar system in Thailand is only 3 Bath! Electricity generation from solar is competitive today even without any subsidy and its cost is predictable!

Electricity price certainty: Every kWh of own consumed and produced solar power gives you a bit more independence from rising electricity costs.
•250.000 kWh solar energy at fixed cost •250.000 kWh "grey power"
•Electricity consumption of 500.000 kWh "grey power" per year with rising cost.

The specific spectral response … … uses indirect sunlight better.
The excellent temperature stabilty … … yields more energy in hot climate zones.
The reduced sensitivity for shadow … … allows new applications.

Schüco thin-film technology Better performance parameters for higher specific yield
Solar yield from every geographical direction Schüco thin-film installations bring higher yields also on roofs in easterly and westerly directions.
In Summary Without space constraints thin film usually gives you better ROI. If space is precious or max power should be reached go for crystalline.

Why rooftop?
Until today the Thai solar market is dominated by large ground mounted MW installations. The future policy will target the roof top segment. Advantages of roof top solutions
• Limited financial exposure and hence widening the private investment base
• Quick installation • 100% internal consumption possible to avoid feed-in
administration work • Independence from grid power in case of power failure
Needs
• Easy installation • Low weight • No roof penetration
