The configurations available below are designed to provide anywhere from 1% to approximately 100% of the energy needs of the client, all of which are grid-tied. 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 photovoltaic (PV) RETS systems are the following (click on the one of interest) :
- SWC-PV : "entry" level system, contributing approximately 1% - 5% of the annual energy needs.
- SWC-PV25 : contributing approximately 15% - 34% of the annual energy needs.
- SWC-PV50 : contributing approximately 35% - 59% of the annual energy needs.
- SWC-PV75 : contributing approximately 60% - 90% of the annual energy needs.
Configurations
This configuration is an "entry" level deployment which enables the individual to generate approximately 1% - 5% 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 develop experience and appreciation in the renewable energy generation. 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 : 4 solar panels @ 80W (Sharp NE-80EJEA) delivering a maximum of 320W (roof-mounted),
- balance of system (BOS) * : includes 1 inverter/charger (Xantrex DR 1524 **), photovoltaic charge controller (Xantrex, C-35), safety DC disconnect-switch, lightening arrestor, 400W resistive load diversion,
- energy storage : 4 deep-cycle batteries (SPS 370AH @ 6V - delivering approx. 12 - 16 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 little or no sunshine).
- SWC-PV system price ¤ : $7,069 ¤¤
- Net Metering optional (add approx. $600 - $1,000 for hardware and installation) - calculated potential energy credit: $0.0 - $0.0 ¤¤¤
At this level of renewable energy generation, Net Metering does not offer any economic benefit due to the relatively low power output of this particular solar array configuration. It would be unlikely that the site would be in a position whereby daily energy requirements fall below the energy generated by the solar array and therefore, there is little opportunity to create surplus energy for export.
| Notes on the SWC-PV : | |
| † | The sliding percentage coverage of renewable energy of the 2.7% coverage @ 12,000 kWh/year consumption would equate to approximately 4.1% 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 1.1KWh/day, and the capacity of the battery array calculated approximately 8.9KWh/day. |

At this level of renewable energy generation, it is economically viable to implement Net Metering, however, 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.
| Notes on the SWC-PV25 : | |
| † | The sliding percentage coverage of renewable energy of the 23.2% coverage @ 12,000 kWh/year consumption would equate to approximately 34.8% coverage @ 8,000 kWh/year consumption. |
