Singapore Cost of solar power
How much does it cost to produce 1 kWh of electricity using solar power?

I made some rough calculation as follows:
 

Cost of solar farm per GW	S$m	2,000
Annual cost amortised 20 years at 4%	S$m	142
Add labor and mgt cost at 50%	S$m	212
Electricity produced in a year at 30%X365X24	GWh	2,628
Cost p kWh	S$	0.081
Electricity tariff in SG	S$	0.279

I obtained a cost of S$0.081 per kWh, compared to the tariff of $0.279.

However, my rough calculation is based on some assumptions about the capital cost of the solar farm, amortization period, labor and overheads, efficiency, etc. 

Conclusion - electricity produced through a solar farm is now quite competitive.

Projects providing solar power electricity to Singapore:
 

Project	Cost	Capacity	Per
	US m	GW	GW
Quantum	5,000	3.5	1,429
Sun Cable	30,000	20.0	1,500
Sunseap		1.4
Total		24.9

The average cost per GW is US$1,500 or S$2,000.
