  • the overhang 2.040 also provides impact protection for the edge of the toughened glass cover and can shield grommet rubber fittings to reduce weathering.
  • the glass cover 2.034 is seated on a peripheral seat provided by the wall extrusion 2.024 and channel and cooperating comer assemblies such as those illustrated in Figure 5, and is sealed thereto.
  • the risers 2.014 in this embodiment are located under and in thermal contact with an absorber plate 2.032.
  • the solar energy can pass through the glass 2.034 and impinge on the absorber plate 2.032 from whence the heat is thermally conducted to the risers 2.014 for delivery to the outlet header.
  • a base plate panel 2.026 doses off the lower side of the enclosure.

  • Figure 3 is an alternative assembly where multiple risers are formed in a unitary manner in a plate 3.038, which is assembled in much the same way as in the preceding description except that the absorber plate 2.032 is not required as the riser plate 2.038 has an upper surface which serves the same function.

  • the cap 5.070 includes an overhang 5.072 which forms a continuation of the extrusion overhang 4.040.
  • the cap overhang 5.072 includes a projection 5.074 which is adapted to be a close fit within the underside of the extrusion overhang 4.040.
  • the cap 5.070 includes a second projection 5.076 which is likewise adapted to fit under the ledge formed by channel 4.044 of the extrusion.
  • the cap also includes a glass seat 5.080 and seal formations 5.078.
  • the cap wall 5.079 extends downward below the glass seat and transversely thereto.
  • the corner wall segment includes a pair of intersecting walls 5.084,
  • the lower spigots 5.092, 5.094 include drain channel slots such as 5.150.
  • a sealant injection point 5.096 communicates with a sealant channel
  • a purge point 5.100 is provided at the top of the sealant channel and the end of the purge point is located so that the end of the purge point is visible beyond the edge of the extrusion, allowing the person injection the sealant to view the purge point to determine when the sealant channel is full.

  • the base plate seat 5.087 accommodates the corner of the base plate inserted in the base plate channel 4.056 of the wall extrusion.
  • the cap 5.070 and corner wall segment 5.082 can include a snap fit arrangement to attach the to the corner wall segment.
  • figure 9 is a corner assembly similar to that of Figure 5, with some of the features of figure 5 such as spigots 5.088, 5.090, 5.094 and 5.092 not being used with the walls 9.084 and 9.086 having their ends being able to be inserted into the extrusion of figure 4.

  • the spigot of the intersection side of the comer wall assembly has been omitted from the drawing to illustrate the through hole 6.156 which is aligned with the drain channel of the omitted spigot and is in fluid communication with a second downward facing recess 6.158 so water can drain from the corresponding extrusion channel to the outside of the enclosure.
  • the drainage outlet recesses 6.154, 6.158 are inboard of the additional recesses 6.155, 6.157 and this assists in preventing water from the exterior of the enclosure reaching the drainage outlets 6.154, 6.158.
  • the intervening wall between the outlet aperture 6.154 and the diversion recess 6.155 diverts incoming water from the edge of the corner junction downwardly so it will preferentially run off.
  • Figure 7 is a cut-away view illustrating the corner assembly with walls
  • the channels 7.150 communicate from the interior of the enclosure across the sealant channels 7.098 to the external aperture 7.152. Should the external aperture 7.152 become obstructed or if the flow is too great for a single outlet, the water will be retained by dam wall 7.160 and flow around the bend to the next drain channel in spigot 7.094. (Because there is a similar drainage feature at each comer of the enclosure, the diversion via the dam 7.160 will provide at least two additional drainage paths, one at either end of the extrusion wall to which the flow from the first drainage channel has been diverted.
  • the drainage path shown in Figure 7 includes an upright segment formed by the recess 7.154 and a transverse segment formed by the drainage channel 7.150. As the upright segment faces downward, this assists in preventing ingress of water via the drainage path. The bend in the path formed by the intersection of the upright segment and the transverse segment also assists in preventing water ingress.
  • Figure 8 is a cut-away view similar to Figure 7 with rectangular cutouts of the base 8.012 showing enlarged detail if the end 8.162 of the sealant channel 8.098.
  • the drainage channel 8.150 can be seen transiting across the sealant channel which is shown in dash line as it is on the rear side of the corner wall 8.084 as viewed in Figure 8.
  • the drainage channel 8.150 passes from the inside of the enclosure, to the exterior recess 8.154.
