    en.wikipedia.org/wiki/Daylighting_(architecture)

    A roof lantern is a daylighting cupola that sits above a roof, as opposed to a skylight which is fitted into a roof's construction. Roof lanterns serve as both an architectural feature and a method of introducing natural light into a space, and are typically wooden or metal structures with a number of glazed glass panels.

  3. Photovoltaic mounting system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_mounting_system

    PV panels mounted on roof Workers install residential rooftop solar panels. The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.

  4. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Matrix Energy Inc. has patented a roof-mounted product called the "Delta", a modular, roof-mounted solar air heating system where south-, east-, or west-facing facades are simply not available. Each ten-foot (3.05 m) module will deliver 250 CFM (425 m3/h)of preheated fresh air typically providing annual energy savings of 1100 kWh (4 GJ) annually.

    This prevents penetrations from fasteners and screws through the metal roof panel that would be used to secure them to the structure with other types of metal roofs. Ancillary Attachments: Roof-mounted HVAC, solar panels, snow guards, and many other products are often attached to standing seam metal roofs. This additional load, attachment ...

    It is important that the rails are level enough for the panels to be evenly mounted. [13] Mounts attach the rails and the entire array to the surface of the roof. These mounts are often L brackets that are bolted through flashing and into the rafters of the roof. Mounts vary in design due to the wide range of roof configurations and materials. [12]

    The electrical components are required to be tropicalized and would have insulation requirements following IEC 60085 Thermal class 200 specifications. The acceleration is set at 0.92 m/s 2 (3.3 km/(h⋅s)), while service braking deceleration is at 1.2 m/s 2 (4.2 km/(h⋅s)) and emergency braking deceleration is at 1.3 m/s 2 (4.7 km/(h⋅s)) per ...

    en.wikipedia.org/wiki/Vibration_isolation

    Air tables consist of a working surface or optical surface mounted on air legs. These tables provide enough isolation for laboratory instrument under some conditions. Air systems may leak under vacuum conditions. The air container can interfere with isolation of low-amplitude vibration. Mechanical springs and spring-dampers
