Rooftop photovoltaic solar systems and methods for installing interconnection wiring for photovoltaic solar systems. Cabling systems can include cable support stands secured underneath shingles. Cabling systems can include molded rubber raceways mounted using raceway clips secured underneath shingles.

A system for securing one or more heating cables to a roof and having one or more apparatuses, each apparatus including a metal base panel and a continuous metal C-shaped channel integrally-formed with the base panel. The channel includes a pair of opposing continuous channel walls creating and surrounding a continuous cavity having a cross-sectional cavity shape substantially identical for at least a majority thereof to the cross-sectional shape of the cable. The channel walls are resiliently flexible to enable receipt of a continuous length of the heating cable within the cavity such that the heating cable is in snug continuous contact with the channel to enhance heat conductance from the heating cable to the base panel.

The Universal Lightweight and Portable Deicing Mat Mat is made of standard top of the line electrically operated and self-regulating standard commercial grade heating cables, which are enclosed between two thin, lightweight, yet strong and protective Neoprene Rubber like sheeting materials, allowing them to endure harshest of winter seasons. These mats can be placed either externally on top of tractor trailers, or they can be placed internally, inside of the tractor trailer, above the ceiling. Both ways can then be secured with custom designed mounting kits, (discussed in further detail). These Deicing Mats can also be used on roofs of residential homes as well as other types of commercial buildings and automobiles.

A roof clip may include a mounting plate including a plurality of infusion holes. A roof clip may include a plurality of cable clamps each including: a first guide, a second guide; and a bendable member joining the first and second guides that is bendable over a heating cable such that, when bent, the heating cable is trapped between the first guide and the second guide.

A snow and ice melt system for a roof may feature heat plates which protect and contact heat cable to distribute heat over a wider area than cable alone. Bends in the plates create attachment structures by which the plates are assembled and by which heat cable is contained.

In an aspect a heating system includes a grounded shield layer made of a continuous piece of metal; a heating element; and a rear adhesive layer comprising of a flame retardant material. The heating element is disposed between the grounded shield layer and the rear adhesive layer; and the rear adhesive layer has a bottom surface that is configured to adhere to at least one of a shingle or an area of a roofing deck. Additionally, a controller is included and is configured to control the flow of electricity to the heating element as a function of a temperature and at least one of a moisture level and a precipitation level.

An apparatus for heating structure or areas adjacent such structure, such as a roof on a building for example, exposed to varying weather conditions and methods of making and use of the apparatus. The heating apparatus can include a heating element and heat supplying components. In one embodiment, the heating apparatus also includes a heatable cover panel and fasteners or other fastening components or materials for securing the heating element and cover panel to the structure. The heat supplying components may include one or more heater cable or heater cable sections penetrating one or more heater cable channels in the heating element. The apparatus may also utilize various insulating and other materials, including paint on exposed surfaces of the apparatus.

Apparatuses, systems, and methods are disclosed for efficient control of a heating element. A sensor is configured to detect a state of water in proximity to a heating element. A switch device is configured to control a supply of power to the heating element. A hardware controller device is in communication with the sensor and the switch. The hardware controller device is configured to adjust the supply of power to the heating element using the switch device based on the state of water in proximity to the heating element.

Air supported structures forming an enclosure via internal pressurized air, and methods of making same, are disclosed. The structures include an outer membrane defining an outer surface of the structure. The structures include an inner liner blanket coupled to the outer membrane via a plurality of spaced baffles extending from the outer membrane into the enclosure, the inner liner blanket and the inner surface of the outer membrane forming a heating pocket therebetween within the enclosure extending along a first portion of the outer membrane. The structures also include at least one input channel in communication with the heating pocket, and at least one heated air system configured to selectively direct a flow of heated air through the at least one input channel and into the heating pocket to heat the first portion of the outer membrane to remove and/or prevent frozen precipitation accumulation on the outer surface thereof.
