Method of assembling an electrical raceway for building integrated solar PV system
View Patent ↗An unitized curtain wall unit houses energy conversion devices (such as photovoltaic modules), and includes integrated raceways/wireways for routing signal and power cables within a building façade or exterior shell structures.
1. A method of assembling the exterior shell of a building, comprising:
attaching a plurality of preassembled, unitized curtain wall modules to structural elements of the building so as to bypass floor structure, each of the preassembled, unitized curtain wall modules including
a rigid frame with glazing material in the frame, the glazing material carrying at least one energy conversion module, the frame having complementary engaging structures adapted to engage the frame with adjacent frames of other unitized curtain wall modules to form and define the exterior shell of the building;
connecting adjacent ones of the plurality of curtain wall modules to form and define the exterior shell of the building, the exterior shell of the building being continuous; and
installing an integrated electrical raceway in a first direction on an interior side of the unitized curtain wall modules, such that respective sections of the raceway attach to respective ones of the plurality of curtain wall modules, such that the integrated electrical raceway forms an interior architectural trim piece within the building, the raceway including
a metal-based conduit adapted to communicate high voltage cabling and low voltage signal cabling along the first direction, and
at least one electrical connector situated on an exterior surface of the conduit and adapted to receive and connect a power output cable from the energy conversion module.
2. The method of claim 1 , wherein the first direction is horizontal.
3. The method of claim 1 , wherein the first direction is vertical.
4. The method of claim 1 , wherein the energy conversion module comprises a photovoltaic (PV) energy conversion module.
5. The method of claim 1 , wherein the metal-based conduit comprises an aluminum conduit.
6. The method of claim 1 , wherein said metal-based conduit includes an additional interior insulating liner.
7. The method of claim 1 , further comprising placing or mounting an integrated control module for the energy conversion module within the conduit.
8. The method of claim 7 , further comprising placing or mounting a management unit for controlling a plurality of control modules within the conduit.
9. The method of claim 1 , further comprising routing at least one of said high voltage cabling and low voltage signal cabling from said integrated electrical raceway through one or more mullions of said unitized curtain wall modules within said exterior shell.
10. The method of claim 1 , wherein said at least one energy conversion device is carried by the glazing material in a vision area.
11. The method of claim 1 , wherein said at least one energy conversion device is carried by the glazing material in a spandrel area.
