Statement of Methodology

Application
 Method
Energy Audit
 A whole house energy audit was provided to align the sizing of the unit with the home energy demands. Recommendations were made where deficiencies were found.

Selection of Site and Application
 SES worked closely with the homeowner and vendor in both the site selection and application. SES worked closely with the homeowner and vendor in both the site selection and application.
Wind and Solar Installation
 A 3.0 kW wind turbine and 2.0 kW of solar panels were selected.
 Inverter The inverter was installed to meet IEEE standards and integrated with sub-metering installed by the utility to gather data.
Net Metering
 Meters power at the connection point to the utility grid, subtracting energy produced from energy consumed. Meters power at the connection point to the utility grid, subtracting energy produced from energy consumed.
Battery Backup
 Stores energy for use during outages and/or non-production times. Stores energy for use during outages and/or non-production times.
MySource Integration
 MySource is an open architecture system developed to allow integration with all data gathered at the end user level. This data is accessible and displayed to the end user and the utility for purposes that are useful to the specific user and organization.

Load Curve Comparisons

One intent of the installation of a DG system is to reduce the amount of generation needed from the utility. A utility’s generation is sized to accommodate peak demands. The DG system’s generation curves will be compared with the utility’s load curves to determine the effectiveness of widespread DG installations on peak demand.


This data on Load Curves is on the SES gateway on MySource and is available to SES Partners. To become an SES parner, click here.

 

Load Factor Analysis

Many utility rate structures are partly based on load factor, which is the amount of time the system uses peak demands versus non-peak demands. This case study will evaluate the effects of widespread DG installations on load factor.

Operational Cost Analysis

Residential
In order to get a proper return on investment of a DG system, consumers must know the operational costs of the system. The factors that are missed more frequently in ROI calculations are maintenance costs (inverter replacement costs, inverter lifespan vs. solar panel lifespan, etc.).
Utility
Distribution grids are primarily designed for the flow of electricity from generation to consumer. Power quality and reliability become questionable with widespread DG installations. These issues carry maintenance and energy costs that Smart Energy Source will evaluate.

AE 2.0 Hybrid 5 kW

Amy Wilson has always believed that going green is the way to be and by producing green energy she is taking the steps necessary to be more green.  The system she has is made up of a 3kW wind turbine, installed in the fall of 2009, and a 2kW solar array that will be completed in May 2010.  The total system will be able to produce over 40kWh per day during the windy day, and 15-20 kWh during non-windy times.  Amy hopes that by setting an example for others she can prove that alternative energy is a sound investment financially and for the environment.
