If you are on grid and want to add solar or wind and sell it to the power company, it is less practical or logical. The Sauer web site shows about 1KW
generated at 20mph wind and lists approximately $8K for the unit. If we assume the wind blows 20mph for half time, that gives 12kWh per day. My
power cost is about 15 cents/kWh so the Sauer unit might pay (save) $1.80 per day or $657 per year. $8K/$657=12 years to break even. Why would one
want to spend money on such an 'investment'? |
