City of South Bend, IN — Department of Public Works ' .` VER EGY' <br />GESC: Central Fire Station & MLK Dream Center Solar PV <br />Technical Approach <br />NEEDS AND SOLUTIONS <br />City of South Bend Indiana has reached out to Veregy to provide proposals for the installation of solar <br />generation systems at the Fire Station and the Martin Luther King Jr. Dream Center, along with other <br />energy savings measures. South Bend has a resident solar panel manufacturer, Crossroads Solar, <br />that manufactures quality solar modules. We have modeled the use of their panels and recommend <br />entertaining the use of their product. Veregy is currently under contract to install Crossroads Solar <br />modules at the Wastewater Treatment Plant. Veregy hires local contractors for all construction <br />activities; our development team has been in contact with K2 Power Solutions, and we look <br />forward to working with them on this project. <br />Fire Station Solar <br />Veregy recommends installing rooftop solar arrays <br />to maximize space available on top of the Fire <br />Station. The solar produced electricity will also <br />provide a positive cash flow by offsetting purchases <br />from the utility for the energy consumed by the <br />building. <br />Veregy has modeled the location suggested in the <br />RFQ. The roof layout was replicated in our solar <br />design software Helioscope along with roof top units, <br />drains, or other objects that could cause shading. <br />Site visits confirmed this layout and allowed us to <br />examine the electrical infrastructure in place. From <br />here the interconnection to the electrical utility was <br />looked at for a best practice way of connecting to the <br />grid. <br />After the maximum amount of solar was placed on <br />the ground, the design was optimized. The projected <br />electric generation from this was compared to the <br />present consumption. The table to the right <br />summarizes our findings. Below, the layout for the <br />array can be found.
