The system will be wired in 4 strings of 12 modules. Custom Solar believes the best location for placing the inverter will be in the main garage area and will work with the City to determine the best location within the building. Custom Solar has the resources to complete the project by the October 15th, 2012 deadline. Preliminary Interconnection Plan The screenshot show below illustrates the preliminary interconnection plan for the PV system at the Nix Farm Property. Custom Solar has spoken to Sam, the Lead Building Inspector for the City of Fort Collins and Norm Weaver, Energy Services Group Engineer for Fort Collins Utility to find out about connecting the photovoltaic system through the use of a line side tap. Norm stated that the City of Fort Collins allows line side taps as long as they are completed on the customer side of the meter (or CT Cabinet) and as long as the line side tap is completed within code. Custom Solar plans to perform a line side tap on the customer side of the CT cabinet in side of the 400A service disconnect. Per our conversations with Sam and Norm Weaver this is an acceptable solution that will cut down on conduit runs, avoid any modifications of the 2nd floor electrical room and reduce system voltage drops increasing efficiencies.

The eGauge has BAl communications capabilities as specified by the data monitoring requirements of the RFP solicitation. Usage and consumption data will be readily available online and can be accessed anywhere with an internet connection. As can be seen in the screenshot above, the online portal will show solar production in green and electricity usage in red. The data can be utilized to identify energy signatures and to inform demand side management strategies to further reduce energy costs. This data is helpful in identifying peak demand and inefficient appliances that should be replaced. Data recording and reporting is managed through the secure online portal and can be ported to other formats for further data analysis. A kiosk view can be displayed for educational purposes, mounted in a traditional interactive kiosk, or wall mounted on any internet enabled device (IE computer, iPad, iPhone, Android phone,...) or displayed through a link on a the City of Fort Collins website. Custom Solar provides turn -key installation and support on the data monitoring, as well as the solar installation. Construction Plan and Schedule The construction timeline for this project is highly compact. A simple system like this will require approximately a week to install completely once Custom Solar mobilizes our entire workforce. In the specific case of this project the overall project duration is driven by the permit review process which generally takes 9 to 15 days to complete and the time required by the utility to install the net meter once the project has passed its final inspection. In Custom Solar's experience the net meter installation usually takes about 2 weeks to complete. As illustrated in the attached schedule Custom Solar is able to mobilize and build this project with our available crews within the anticipated project window; completing construction activities 3 weeks before the project deadline. Custom Solar achieves this with a standard Monday through Friday workweek and a 9 AM to 5 PM working day The durations of activities accounts for reasonably small delays that may arise, however should the project suffer more drastic delays Custom Solar maintains alternate crews that will be available to transfer into this project and provide assistance with acceleration. This schedule represents a worst case scenario wherein all the durations are the maximum probable to ensure that when we schedule our crews to work on the project they will be available and able to devote their full attention to this project. COSEIA Membership Custom Solar is currently a member of the Colorado Solar Energy Industries Association (COSEIA). Willie Mein, owner and founder of Custom Solar, has been a member of COSEIA since 2007.

At Alta Vista Elementary School, a 56.6 kW, utility -connected system was installed. This system consists of two arrays. The first has 153 solar panels that are mounted parallel to a standing seam metal roof facing south-southeast. The second array consists of 78 solar panels that are ballast -mounted at 101 in order to minimize impacts of wind loading and allow the collectors to shed snow to maximize production. Custom Solar successfully worked with the roofing manufacturer to ensure the installation of all racking and components would meet the roofing manufacturer's requirements, and retain the original roof warranty. A data monitoring system was also installed in order to track the systems performance, and be on public display for the students and faculty. At the district's Agricultural Farm property, a 1.96 kW, utility -connected, ground -mounted system was installed. This system has only one array, consisting of eight of the same type panels that were installed at Alta Vista Elementary School. The array was mounted at the appropriate angle and direction in order to maximize production. A monitoring system was installed here as well which tracks the production of the array. At Johnson Junior High School, Custom Solar installed a monitoring system in order to track and monitor the production of the existing wind turbine that is onsite. Custom Solar used wireless relays to transfer production data from the wind turbine interconnected to the electrical system of an accessory building to the school's network. At McCormick Junior High School, another monitoring system was installed in order to track and display the production of the existing wind turbine onsite. Custom Solar demonstrated their knowledge in Solar Engineering as well as their versatile installation experience at Alta Vista Elementary School and the Agricultural Farm. Both systems were well executed in a professional manner. Custom Solar also met all City of Cheyenne and Laramie County building and electrical codes.
