The following graphs show the Average Daily Production in kilowatt-hours per day (kWh/Day) for Bergey Excel-S 10kW's located at various locations throughout New York. Turbine owners submit production meter readings of their turbines at monthly intervals and daily production values are averaged over meter reading intervals.

For example: On 3/31/08 a meter reading of 350 kWh is submitted and on 4/30/08 a meter reading of 1100 kWh is submitted. The total time period production of 750 kWh is divided by the number of days between the two readings, 30 days,  to get an average daily production of 25 kWh/day from 3/31/08 to 4/30/08.

The location of the turbine is identified in the key followed by its assigned region. To increase the clarity of the information and to show regional trends, data is broken into regions based on general location within New York. Due to the nature of the graph, a minimum of three meter readings are necessary for a trend line to be shown. The graphs represent readings from 2009.
