Educational Solar Array

About the project

In 2013, the board of directors at Great Lakes Energy approved a solar project to provide education about alternative renewable sources of energy.

The display, installed in April 2014 outside the GLE office in Boyne City, features two working 5 kilowatt (kW) solar arrays, one fixed and the other tilting. The combined 10kW array is large enough to provide the energy needed for an average residential GLE member’s home.  The tilting array will be repositioned twice a year, in the spring and fall.

Data collected can be seen on a live monitor in the Boyne office and will also be shared in publications. The panels are located near the parking lot and are available for public viewing.

To view the output of the panels, follow the links below:

kW is the measure of power.

kWh is the measure of energy. GLE members are billed for energy usage on a kWh basis. The average full-time residential member uses around 800 kWh per month.

kWp is the peak kW the solar array can generate when all conditions are perfect, which is 5 kW for the GLE arrays.

Members interested in investing in solar at their own residence or business should consider all the factors such as panel location, size and cost, available incentives, permits, amount of energy needed, application (space heating, water heating, power generation) and more.  These are things best discussed with a professional solar dealer familiar with your area.

The display is mainly for educational purposes, but is also net metered so that our office uses the energy generated.  Net metering is available to members who wish to generate power through a renewable source. Any excess energy generated is then credited to your electric bill.
