Dovetail Solar and Wind installed a
2kW hybrid wind-solar energy system at my home on North Coolville Ridge Road in Athens, OH,
in the summer of 2004.
I
received a matching funds grant from the Ohio Department Of Development
Office of Energy Efficiency to pay for 1/2 of the $20K installation
costs.
·
~$5K for the solar panels
·
~$2.5K for the wind generator
·
~$4K for installation,
·
the remainder for the tower, the inverter, the
batteries, and balance of system
The system is utility interactive and has a
battery backup system.
o
The renewable energy system consists of:
§
a 960W ground mounted solar array (8 BP SX 120U panels)
§
a 1kW wind turbine (African Wind Power 3.6 with a
12 foot turbine diameter) mounted on a 64 ft high tower
§
a 2kW grid-connected inverter (Outback
FX2000).
§
Four 12V Trojan Deep Cycle batteries (series-connected
,
48 V, 105 Amp hours, ~5kWh storage)

Transportation:
In town - Trek 720 (bike commuter) Longer trips - 2006
Toyota Prius II
 
> Fuel economy for the Prius for short trips in hilly Athens OH:
42 - 47 mpg
> Fuel economy for longer trips (to Cincinnati or towards
East Coast) 52 - 61mpg
> I have experienced lower fuel economy
in the winter than in the summer.
> Overall fuel economy for the first 20,000 miles = 49
