Solar, wind: technology, cost, potential, applications
Palang Thai
Solar PV
Costs: Grid-connected:
$3,000 to $6,000 per kW for grid-connected projects, (LCLT Common Ground is coming in at $6 for 36 kW) $0.15/kWh to $0.22/kWh (98% fixed cost) for grid-connected
Off-grid Typically $8,000 to $10,000 per kW $0.25 to $0.45 per kWh (competitive with diesel)
Industry trend: 70% growth in 2008. Over 40% average over past decade Potential: 14 km x 14 km enough to meet Thai peak load Capacity factor: 0.15 Issues: expensive, intermittent
Solar Photovoltaic (PV) -- costs
$3,000/kW to $6,000/kW (depending on system size) $0.15/kW to $0.22/kWh in 2005 for 10 MW plant in Phoenix,
Arizona, USA in 2005.

How solar photovoltaics (PV) works
Solar photovoltaics
fastest growing power generation technology, with a 70 percent increase in existing capacity worldwide to reach 13 GW in 2008. www.REN21.net
Solar Photovoltaic (PV)
Capacity factor: 0.15 Power production coincident with peak (air-conditioning) load
Thai government solar home program
203,000 solar home systems>20% failure rate within first year in Tak
Wind• Costs:
– Grid-connected:• EURO 1300 per kW for grid-connected projects,
• $0.09/kWh for large (80 to 200 MW installation)
– Off-grid• Comparable with solar PV
• Industry trend: 29% growth in 2008.• Potential: not great in SE Asia (but OK in Vietnam). China
excellent, especially north• Capacity factor: 0.15• Issues: expensive, intermittent. Some concerned about
bird kills, but is tiny fraction of kill from power lines, other power plants
Wind -- Costs
$0.09/kWh for 80 to 200 MW wind power plant in Washington State, USA. (Source: Energy Northwest)
installed cost averaged €1,300 per kilowatt in 2007 (source: www.gwec.net)
Wind energy potential world-wide
SE Asia low compared to much of the world
Wind -- resource
Thai wind potential: 1600 MW (?)
