If you want a company with a track record, they're definitely the ones. A Jacobs wind turbine was installed for a South Pole expedition in the 1930s and was later found to be turning in the 1960s. The Jacobs is one wind turbine that should be considered for large residential, farm/agricultural, and small commercial. Overall the Jacobs 31-20 is available for 20,000 to 30,000 KWH demands. They are recognized by the USDA for the 9006, REAP, and REEP grant and loan programs.
TYPICAL INSTALLATION COST
A typical installation run around $110,000 with state grants up to $59,000 (limited to certain States), USDA grants of $25,000 or more (for farm and rural small business) and USDA Loans of $25,000 or more. In addition you are now eligible for a Federal Investment Tax Credit of 30% of the installed cost and Wind Recs under certain State programs. As you can see a Wind Turbine can pay for itself very fast. Call the office for more details.
The speed is also one of the slowest at 175 rpm amongst these size turbines making it a quite one. |
