My Home Renewable Energy System
 
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 DOD 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)
See the Table of my Monthly Home Energy Use and Production showing that my house is a net energy producer.

> 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
