hi all In minnesota we get about 1400 Wh/Wp/yr (no losses) , if a system is designed for 3% voltage drop loss, this is 42 Wh/yr/Wp or 1050 Wh/Wp for 25 yrs. if the wire is solid instead of stranded this saves 1Wh/yr/Wp or about 25 Wh/Wp for 25 years. In terms of money if the customer is paying 10.00/watt installed and his electric rate is 40 cents/kwh he saves 0.0004$/year/Wp more if you use solid wire. That's 40 cents per 1kW installed.
