PROJECT: Mixed-Use Commercial 40 kW Array Designed and Installed by Prospect Solar, LLC Modules: (162) Sharp 240 Watt Inverters: Enphase Energy Micro-Inverters Monitoring: Enphase Envoy Racking: Custom Light-Gauge Steel Substructure Roof: Hot Rubberized Asphalt Project Location: District of Columbia, NW Commissioned: 6-18-2012 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves Project Description: Prospect Solar was contracted to design and install a photovoltaic array that would be housed on top of a five-story commercial building, raised above equipment located on the roof. Prospect Solar designed a custom light-gauge steel structure on approximately a 10˚ angle to increase sun harvest. The system consisted of (162) SHARP NU-U240F1panels, each at 240 watts, combined for a total array of 39.84kW. The custom steel canopy not only allowed better sun harvest, put also provided cover for the rooftop and equipment below while allowing plenty of cooling for the photovoltaic modules. The array, while one concurrent plane, actually was composed of a 5kW array, a 15kW array, and a 20kW array fed into three separate meters, each with their own micro inverters and generator identification. The end result was the largest privately owned system in DC at that time, while also offsetting a large portion of the five-story buildings energy load. It is important to note that a new warranted roof was installed by Prospect Waterproofing to ensure the roof lasts as long as the solar installation.



PROJECT: Erkiletian: The Asher built by KBR 17 kW Array Designed and Installed by Prospect Solar, LLC Modules: (70) Kyorcera 235 Watt Inverters (3) Power-One 5000W Aurora Monitoring: Locus LGate310 Racking: Sollega InstaRack 10° (Ballast Mount) Roof: TPO Project Location: Alexandria, Virginia Commissioned: 1/7/12 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves Project Description: Prospect Solar was contracted to design and install a photovoltaic array on top of a new residential apartment complex in Alexandria, VA. The mid-rise apartment complex desired to offset the electricity price of its 206 apartments by adding solar to the flat roof top. The series of (70) Kyorcera 235 W modules are orchestrated around the roof surface making way for HVAC and other building equipment, composing a16.45 kW photovoltaic system. A ballast-mounted system was employed in conjunction with (12) anchors that had been designed into the roof structure at its construction. In addition to Prospect Solar being able to maintain the roof warranty, this was a great new construction project, especially since the architect of the facility had been forward thinking about solar, allowing our design and engineering staff to easily accommodate solar access. An additional feature Prospect Solar included, was the Locus Energy Monitoring system. This monitoring system was designed to have a kiosk display in the tenants’ business center that allows the facility to share the system production information.



PROJECT: District of Columbia Sustainable Energy Utility (DC SEU) 71 kW Total Designed by Prospect Solar / Installed by Prospect Solar and Trusted Solutions Group Modules: AUO, Hanwa, and Canadian Solar Inverters: Enphase Energy Micro-Inverters and SMA Monitoring: Enphase Envoy Racking: SnapNRack (Flush Mount) Roofs: (Mostly) Asphalt Shingle Project Location: District of Columbia, SE and NE Commissioned: On-going Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: The DCSEU of Washington, DC contracted Trusted Solutions Group and Prospect Solar in an initiative to reduce energy consumption per capita, increase the amount of renewable energy generators, reduce load on conventional energy systems, reduce energy cost of low-income housing, and to stimulate green-collar jobs in the DC area. The ongoing development will continue to creatively finance solar arrays for low income households. Each of the homes selected received a photovoltaic array attached to the residences roof by a flush-mount system. The expected savings per house are a 25%-40% reduction in energy cost. Prospect Solar also utilized Micro-Inverters for these projects, so the homeowner can monitor online the performance of each individual module. Through this program so far Prospect Solar, TSG, and DCSEU have contributed a total of 71 kW of renewable energy to the DC Renewable Energy Portfolio.



PROJECT: Foreign Embassy ClientDesigned and Installed by Prospect Solar, and Commercial Express HVAC Inc. PV Modules: (8) AU Optronic 240 Watt SHW Collector: (4) Heliodyne Gobi PV Inverter: SMA America Sunny Boy 2000W Racking: Sollega InstaRack 10° (Ballast Mounted) Roof: Hot Rubberized Asphalt Project Location: District of Columbia, NW Commissioned: 12/14/2012 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: Prospect Solar was contracted to design and install a solar thermal (or a solar hot water) collector as well as a photovoltaic array. The Client’s building houses about thirty tenants in their in-facility apartments, and was looking for a reduction on their energy costs attributed to water heating. The solution that Prospect Solar selected was a (4) panel, Heliodyne Gobi Solar Thermal Collector. This collector boasts 95% solar accumulation, a 1.25 gallon/minute flow rate, and has also been ranked by SRCC as a top ten OG-100 collector panel. Using a minimal 20 penetrations, the roof mounting system for the SHW collector was seamlessly flashed by Prospect Waterproofing (who was also installing the roof) to guarantee against leaks and preserving the manufacturer’s roof warranty. The result is a projected 70% reduction in hot-water energy costs. Since the solar-thermal system utilizes electric pumps to transport the glycol-water mixture from array to storage tank, Prospect Solar also designed a 2kW photovoltaic array to offset the added electrical load of the pumps. The 1.92 kW array is made up of (8) AUO 240 watt photovoltaic modules, and is utilizes Prospect Solar’s preferred attachment of ballasted mounting.



PROJECT: Commercial Facility 38 kW Array Designed and Installed by Prospect Solar Modules: (148) LG 260 Watt Inverter: (3) Power-One 12000W Aurora Inverters Monitoring: Locus LGate310 Racking: Sollega FastRack 5° (Ballast Mounted) Roof: Built Up Tar & Gravel Project Location: District of Columbia, NW Commissioned: 4/10/2013 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: A DC cartage and trash removal service contacted Prospect Solar to install a solar photovoltaic energy system on the roof of its new facility. This project allowed Prospect Solar to utilize both its solar expertise, as well as its roofing and waterproofing experience. Prospect Solar wanted to insure the longevity of both solar system and the roof, so Prospect Waterproofing was subcontracted for minor remedial roof/waterproofing repair. Once remediation was completed, Prospect Solar installed a 38.5 kW PV array, consisting of (148) Black LG 260 Watt modules connected to (3) Power-One 12000 W Aurora Inverters. The mounting system employed was the Sollega 5° FastRack System that utilized recycled, high-density polyurethane ballast trays to attach to the roof without the need of penetrations. Underneath the ballast trays, Prospect Solar also opted to install an EPDM strip used as a sacrificial membrane under the ballast trays. This sacrificial membrane was integrated to avoid damage to the waterproofing of the roof. The 38kW PV array consisted entirely of Buy American Compliant components, and is estimated to offset the energy bill by 73%.



PROJECT: Catoctin Creek Distillery 41 kW Array Designed and Installed by Prospect Solar Modules: (158) LG Solar 265 Watt Inverter: (158) Enphase Energy Micro-Inverters Monitoring: Enphase Envoy Racking: Sollega FastRack 5° (Ballast Mount) Roof: TPO Project Location: Purcellville, Virginia Commissioned: 9/17/2013 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: Prospect Solar was contracted by a local distillery to offset the electrical load at its new location in downtown Purcellville. The design elected for a ballasted system on the gently-sloping south facing roof, using the Sollega FastRack 5° tilt system placed on sacrificial EPDM membranes to protect the new TPO roof surface. (158) LG Electronics 265 Watt Modules, all black, were selected to compose the 41.87kW array. Enphase Micro-Inverters were also selected to negotiate periodic shading from critical roof vents and a historic chimney. The overall system is projected to produce roughly 51,200kwh’s per year, which is enough to power about 4.5 Virginia homes’ electrical needs. As far as environmental benefits, this system is projected to offset 1,939,824 lbs of CO2 over the next 25 years, which is the equivalent to planting 16.6 acres of trees. In addition to the Federal Tax Credit, this system also received financial incentive from a USDA grant promoting advanced energy systems for rural businesses and farms. At time of installation, this facility marked the 23rd largest private solar array in Virginia, and the largest installation in the City of Purcellville.



PROJECT: Rural Farm 21kW Solar ArrayDesigned and Installed by Prospect Solar Modules: (84) REC Solar 250 Watt Inverter: (2) SMA America Sunny Boy 9000W Monitoring: Locus LGate101E Racking: Schletter FS System (Ground Mount) Project Location: Purcellville, Virginia Commissioned: 11/15/2013 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: Prospect Solar was contracted by a start-up farm in Purcellville, VA to design and install a 21kW solar array. The array, which was ground-mounted using the Schletter FS System with concrete footings, was designed to minimize the amount of active farm space used to place the array. The array was divided into (2) equal sections, approximately 11’x70’ (770ft²) each, and was placed within a containment fence to minimalize animal impact. Each array section is composed of (42) REC Solar 250 Watt modules and a SMA America Sunny Boy 9000W inverter. The array is mounted at a 20° tilt, and is projected to produce 27,716 kWh per year, offsetting 98% of the farms annual electrical use. The farm, which specializes in cattle, poultry, and garlic also utilizes geothermal heating and cooling. Through the help of a USDA grant and reduced electrical savings from solar (projected around $78,000 over the next 25 years) the farm is planning on expanding its operation.



PROJECT: Residential 5.7kW Solar ArrayDesigned and Installed by Prospect Solar Modules: (19) LG Solar 300 Watt Inverter: (19) Enphase Energy Micro-Inverters Monitoring: Enphase Envoy Racking: SnapNRack (Flush & Standing Seam Mount) Roofs: Asphalt Shingle & Seam Metal Project Location: Waterford, Virginia Commissioned: 11/21/2013 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: A customer in the Village of Waterford, a National Historic Landmark, desired a solar energy system for their 197 year old home, and contracted the specialty project with Prospect Solar. In addition to standard design, permitting, and installation, special design considerations were incorporated to meet Loudoun County Historic District Guidelines in order to receive zoning approval. The design was very sensitive to the heights of the (19) LG Solar 300 watt modules on both the asphalt shingle and standing seam roofs, and also needed to eliminate any visibility from public right-of-ways. Micro-Inverters were used to accommodate multiple roof faces and tilts, and were hidden below the all black panels on the racking systems. Additional provisions were included as well as collaboration and a hearing with the Historic Review Board to gain their approval. The end result, was a system producing an estimated 55% of the customer’s electric bill, saving over $600 in energy costs per year.



PROJECT: Residential 9.9kW Solar ArrayDesigned and Installed by Prospect Solar Modules: (33) LG Solar 300 Watt Inverter: (33) Enphase Energy Micro-Inverters Monitoring: Enphase Envoy Racking: SnapNRack (Flush Mount) Type: Asphalt Shingle & EPDM Flat Project Location: Vienna, Virginia Commissioned: 9/25/2013 Personnel Involved: Jon Hillis, Andrew Skinner, Kevin Graves, Nick Messer Project Description: This project was contracted by a customer in an upscale neighborhood with the desire to operate their solar energy system under the Solar Purchase Program ($0.15/kWh Feed In Tariff). To make the most of the investment, Prospect Solar was contracted to design and install at 9.9kW solar array using high-powered (33) LG Solar 300Watt modules and (33) Enphase Micro-Inverters. (21) Panels were flush-mounted on the steep 42° pitched roof, and (12) panels were stand-off mounted on the flat, EPDM roof. As with all of Prospect Solar’s installations, OSHA safety regulations were strictly enforced. For the racking penetrations on the flat roof, Prospect Solar’s installers (dual trained in roofing and waterproofing) performed flashings in order to ensure the connections were watertight. This large residential system will produce roughly 63% of the home’s electric usage, and will be the equivalent of planting 4.1 acres of trees over the next 25 years, which is also the lifetime of the manufacturer’s warranty on the solar energy equipment.



PROJECT: Residential 10.7 kW Solar ArrayDesigned and Installed by Prospect Solar Modules: (32) SunPower X21 335W Inverter: (1) Solar Edge 10000SE Monitoring: Solar Edge Racking: Unirack flush mount Type: Asphalt Shingle Project Location: Chantilly, Virginia Commissioned: 8/10/2014 Personnel Involved: Andrew Skinner, Nick Messer, John Wenmen, and Matt Steiner Project Description: This client’s goal was very simple – offset as much electricity as possible, while making the system aesthetically pleasing. To achieve this goal SunPower’s 21.4 percent efficient all black solar modules were chosen. These modules are the most efficient commercially available panels in the world. The home owner was previously on the board of his home owners association and wanted to lead by example to show his community what is possible in terms of generating your own solar electricity. The modules are mounted on two separate roof pitches one facing dead south and the other facing south west. The system is projected to offset about 70% of the homes total electric usage – the meter will certainly be spinning backwards during the summer months.
