Commercial Solar Case Studies
For the moment we've put together two case studies of installations that address certain customer needs.
The tabs on this page correspond to the following:
| Standing Seam | A Mullica HIll Church utilizes its standing seam roof to support the pv system. |

122 degrees | |
Module: |
Siliken SLK60P6L | |
Inverter: |
Fronius | |
Racking: |
Iron Ridge |
This recently built Church was looking for an system that would take advantage of its southeast facing roof but not detract from the overall aesthetics of the building. The roof was comprised of standing seam that created a perfect supporting structure for the solar array. The standing seam allowed for the use of S-5 clamps to attach the solar racking and therefore there was no penetration of the roof surface. Electrical entry was made into a horizontal wall also reducing the chance of water intrusion with conduit running through existing building cavities used for other HVAC piping thereby eliminating any public view of electrical conduit from the system to the electrical room.

For this installation, cost and performance were points of interest. By constructing the pole barn with a 6/12 pitch and facing it just off due south to conform it to other structures, almost optimal performance was expected. Generally not a candidate for microinverters, a relatively shade free structure such as this could have done well with a central inverter setup, however, the system owner was attracted to the Enphase 25 year microinverter warranty as well as the heightened energy harvest capability of the Enphase units. Even using component derate factors, the system outperformed PV Watts estimates in the last year by a good margin.
OnPeak worked with the pole barn builder to specify the requirements for the rafters and purlin structure layout so that the building would allow for the weight and wind loading of the system. With a building designed for solar this also allowed for a quick installation. Monitoring is accomplished through the Enphase monitoring system with the addition of wireless devices to allow communication with the broadband access point.
To take advantage of a NJ promotion with in State vendors, the system owner selected MX Solar modules. Although MX Solar has reworked its presence in the US (like many other module manufacturers), we found their modules to be of the highest quality with a very robust frame and glass.
