Anyone know if how many years of usage it would take to gain back the cost of the $1000 panel kit?

- mchannon 14y agoIt depends on: Where (climate) and Location on house (shading) and Electricity Price and Discount Rate and *Utility/Government Incentives (vary by utility) but at $5.50/W (assuming installation is free) in a place like Phoenix, you're looking at about 27 years before incentives, about 20 years after. $5.50/W is kinda steep nowadays, but probably a decent deal for a hobbyist-sized system of this nature.
- K2h 14y agosure, ballpark math: 10c per KW hour, approx a 200W panel. assume 10 perfect hours of sun each day (unlikely), then you have 20c a day. $4 a month, $50 a year, so that takes you 20 years (simple math, none of the typical MBA voodo applied).. and its the weekend my brain is on holiday and no spreadsheet on the ipad, so that could be totally wrong.
