The configurations available below are designed to provide anywhere from 25% to approximately 100% of the energy needs of the client. The design of each configuration is based upon energy consumption of approximately 12,000 KWh/year. These configurations are scalable and therefore, for small to medium sized businesses, requiring a similar coverage, the architecture of each version can be modified to suit.
A RETS user, along with any configuration described below may enhance the positive economic benefit through employing a variety of energy conservation measures such as high-efficiency-low-energy light bulbs, and the replacement of older and energy inefficient appliances with Energy Star compliant appliances. Together with a RETS deployment and energy conservation measures, a RETS user may realize an additional savings of 5-20% energy per year.
The configurations available from SWC for stand-alone turbine RETS systems are the following (click on the one of interest) :
- SWC-T : "entry" level system, contributing approximately +/- 17% of the annual energy needs.
- SWC-T50 : contributing approximately +/- 50% of the annual energy needs.
- SWC-T100+ : contributing approximately +/- 100% of the annual energy needs.
Configurations
This configuration is an "entry" level deployment which enables the individual to generate approximately +/- 17% of their energy needs (percentage of coverage based on approximately 12,000 KWh/year consumption - percentage of coverage scaled upwards or downwards depending on actual energy consumption determined at the site) † , servicing specific electrical loads (appliances, lights, electronics) to reduce the power bill or cottage deployment, to develop experience and appreciation in the renewable energy generation. The table below depicts the annual potential environmental benefits as a result of this RETS deployment. It is clear that renewable energy generation dramatically reduces the pollutants generated from traditional electrical energy production. The table below depicts emissions avoidance based on the indicated power generation fuel mix found in Ontario of nuclear:51%, hydro:22%, coal:19%, natural gas:7%, other:1%.

In general, this configuration will include the following components for the system price indicated:
- front-end : one Bergey or Aeromax 1KW wind turbine and 22m guyed tubular-tower (not including tower pipe),
- balance of system (BOS) * : includes 1 inverter/charger (Xantrex DR 1524 **), turbine controller, one safety DC disconnect-switch, lightening arrestor, 400W resistive load diversion.
- energy storage : 8 deep-cycle batteries (SPS 225AH @ 6V - delivering approx. 12 - 24 hrs ***), (battery array is optional, however, without a battery array, the RETS user may experience a power interruption should the grid fail during periods of no wind).
- SWC-T system price ¤ : $9,664 ¤¤
- Net Metering optional (add approx. $600 - $1,000 for hardware and installation) - calculated potential energy credit: $0 - $202.77 ¤¤¤
At this level of renewable energy generation, Net Metering may offer some benefit such as approaching a Net "0" electricial utility bill by virtue of extended periods of down-time or vacancy during which minimal energy draw is occurring. With the current scheme, and this particular configuration for a main residence or small business, in general, the small amount of surplus energy generated may not off-set the cost of the instrumentation and installation costs of Net Metering until well into its second or third year of operation, however, should the system be upgraded or expanded, the configuration is prepared to offer some additional economic benefit with respect to the upgrade.
| Notes on the SWC-T : | |
| † | The sliding percentage coverage of renewable energy of the 17% coverage @ 12,000 kWh/year consumption would equate to approximately 26% coverage @ 8,000 kWh/year consumption. |
| * | SWC reserves the right to replace components due to their availability or unavailability with similar performing components, and therefore, base pricing may change. Current exchange rates may also affect base pricing for components sourced from the USA or Europe. |
| ** | The inverter sizing is based on a peak consumption of approximately 1 - 1.5 kW/h. Higher values determined during the feasibility analysis for peak consumption will require a larger inverter capacity and therefore, base pricing may change. |
| *** | values based on RETS coverage of approximately an average of 7KWh/day, and the capacity of the battery array calculated approximately 2.9KWh/day. |
| ¤ | System price does not include costs of site preparation and RETS installation. See additional notes below for a description pertaining to these costs :

Energy credits values will vary dramatically for each installation due to variations in availability of wind speed and insolation levels. Net Metering does not produce any cash value benefits, but rather energy credits applied to the utility bill. Click Net Metering to learn more details. |
This configuration is designed to generate approximately +/- 50% of the energy needs of the client, the range falling between 34% to 70% (percentage of coverage based on approximately 12,000 KWh/year consumption - percentage of coverage scaled upwards or downwards depending on actual energy consumption determined at the site). † The table below depicts the annual potential environmental benefits as a result of this RETS deployment.

In general, this configuration will include the following components for the system price indicated:
- front-end : one Southwest 3KW wind turbine and 22m guyed tubular-tower,
- balance of system (BOS) * : includes 1 inverter/charger (Xantrex DR 1524 **), turbine controller, one safety DC disconnect-switch, lightening arrestor, 400W resistive load diversion.
- energy storage : 4 deep-cycle batteries (Surrette 650AH @ 4V - delivering approx. 15.1 KWh ***), (battery array is optional, however, without a battery array, the RETS user may experience a power interruption should the grid fail during periods of no wind).
- SWC-T50 system price ¤ : $25,033 ¤¤
- Net Metering optional (add approx. $600 - $1,000 for hardware and installation) - calculated potential energy credit: $67.02 - $476.23 ¤¤¤
At this level of renewable energy generation, the economic viability to implement Net Metering, tends to derive more econimic benefit from Net Metering through the client's expectation with respect to approaching a "zero" energy consumption balance electricity bill, however, payback for the Net Metering installation and meter may occur within the 2nd or 3rd year of operation.
| Notes on the SWC-T50 : | |
| † | The sliding percentage coverage of renewable energy of the 47% coverage @ 12,000 kWh/year consumption would equate to approximately 71% coverage @ 8,000 kWh/year consumption. |

This configuration is designed to generate approximately +/- 138% of the energy needs of the client (percentage of coverage based on approximately 12,000 KWh/year consumption - percentage of coverage scaled upwards or downwards depending on actual energy consumption determined at the site). † The table below depicts the annual potential environmental benefits as a result of this RETS deployment.

In general, this configuration will include the following components for the system price indicated:
- front-end : one Bergey 7.5KW wind turbine and guyed lattice-tower,
- balance of system (BOS) * : includes 1 inverter/charger (Xantrex DR 1524 **), turbine controller, one safety DC disconnect-switch, lightening arrestor, 400W resistive load diversion.
- energy storage : 4 deep-cycle batteries (Surrette 650AH @ 4V - delivering approx. 15.1 KWh ***), (battery array is optional, however, without a battery array, the RETS user may experience a power interruption should the grid fail during periods of no wind).
- SWC-T100+ system price ¤ : $59,847 ¤¤
- Net Metering optional (add approx. $600 - $1,000 for hardware and installation) - calculated potential energy credit: $67.02 - $476.23 ¤¤¤
At this level of renewable energy generation, the economic viability to implement Net Metering is diminished by the fact that under the current scheme, one is able to transfer surplus energy to the grid and is less than or equal to the amount of energy consumed, however, given this configuration is approaching 100% renewable energy production, there is little or no "room" left for the purpose of Net Metering and therefore, the proposed standard offer contract would be more financially beneficial.
