Hollow building surface panel and building surface system

A building surface panel having a first end, a second end, an upper side, and a lower side, the building surface panel comprising:

• a hollow panel body including a front wall at a front side of the building surface panel and a rear wall at a rear side of the building surface panel that enclose an interior space;
• a fastening strip attached to the panel body and extending along the upper side of the building surface panel, wherein the fastening strip and the rear wall of the panel body form a rear attachment surface of the building surface panel that is configured to engage a support structure;
• an overhang attached to the panel body and extending along the lower side of the building surface panel, the overhang being configured to overlap at least a portion of a fastening strip of a lower neighboring building surface panel having a similar configuration, wherein the overhang and the front wall of the panel body form an exposed front surface of the building surface panel,
• a rear-facing engagement surface disposed at the upper side of the building surface panel;
• and
• a front-facing engagement surface disposed at the lower side of the building surface panel, the front facing engagement surface being configured to engage a rear facing engagement surface of the lower neighboring building surface panel,
• wherein an upper side of the panel body includes a first angled surface at the front side of the building surface panel and a lower side of the overhang includes a second angled surface at the front side of the building surface panel, the first and second angled surfaces are configured such that, when the front-facing engagement surface of the building surface panel engages a rear-facing engagement surface of the lower neighboring building surface panel, a front-facing V-groove is formed between the second angled surface of the building surface panel and a first angled surface of a lower neighboring building surface panel having the same configuration.
