Solar windows - enough, per panel, to charge two (2) cell phones each day.
 
- If they face south.
- If the day is sunny.
- At a cost of +/- US$182 per square foot, US$2,000 per square meter.
 
Phone Charge: 6 watts (max) per hour.
Assume 4 hours to charge a phone.
24 watts per charge.
48 (use 50) for two phones.
In twenty (20) days, those windows will generate 1KWH of power, at the national average of US$0.13/KWH.
 
Really?
