Hemispherical Snapshot

The Solometric Suneye is a tool that photographs and analyzes the sky for potential direct solar radiation. By performing 4 sessions (2 positions on the wall during winter and summer), we were able to determine the optimum angle, azimuth, and placement of the photovoltaic array.

Photoltaic = Electricity

We intend to offset the energy consumption of the Storrs building by feeding 120V/208V AC intoa lighting distribution panel. The power produced will be on metered and the information shared with the University and local community via internet. This module will serve the public as a demonstration of the potential and feasibility of Solar Energy.

Storrs Electrical

4.8 Kw of DC electricity will travel be piped along the wall and into the Storrs Mechanical Wing. It will be converted and monitored by equipment mounted to the space on the wall adjacent to the lighting panel, approximately 90’ from the panels themselves.

Structural Details

4x3x1/4” and 3x3x3/16” Structural Steel Angle fabricated by Steel Fab, Charlotte.

1/4” Rod System by Hayn Architectural Systems, Connecticut.

Structural Details - Tension Cables

Tension cables provide rigidity by both immobilizing the various pin connections and tying the columns together into a single unit.

Cable Terminal Nodes

Hayn Architectural Systems : SS 306 Terminals + CableSteel Fab, Charlotte : Miled Steel Structural Angle and Plate Fabrication

Discs cut from 1/4” steel plate will be welded into the primary structural angles. They wil serve as terminal points for the cable system while holding the two Angles together.

Connection A

Connection A

Connection A

1/4” Steel Plate composes the interface between the 4x3x1/4 primary structure and the 3x3x3/16 secondary. It will be fabricated into tabs that negotiate the camber resulting from rotation in design.

Connection B

Connection B

Primary to Secondary

These modified tabs are designed to be efficient at fabrication. Both interface tabs come from the same 1/4” steel plate.

Structural Interface

Achoring + Footings

The elevated footings display the simple pin connection that flows from the gradually slendering columns as they delicately provide adequate structural support for the photovoltaic panels.

Connection C

Connection C

ConcreteThe footings will be of concrete left over from construction on campus. They are placed 14’ O.C. , this is done to match the concrete reinforcement in the wall, which runs vertically every 24” O.C.
