A heat panel system for preventing ice formation about a roof or gutter includes at least two heat panels that are connected using a fastener. The heat panels each include a body including at least one channel configured to accept a heating element. Tongues and grooves or other mating arrangements on the panels and the fastener permit two panels to be joined by a fastener so as to inhibit relative lateral movement and enhance heat transfer between panels. A single panel or a multi-panel system can be mounted directly on the roof, and/or a single panel system can be mounted in a gutter. By using these heat panels and fasteners, heat panel systems of varying widths can be made using the same supplies.

A snow guard assembly heated within one or more snow guard tubes. Heating of the snow guard tube prevents excessive accumulation of snow and helps prevent snow build up and spill over above the top of the snow guard. The tubes can be length-wise separable to place and service the heating elements. The heating element can be standard heat tape or infrared LEDs. The snow guard tubes can optionally have a non-uniform cross-sectional thickness to direct the heat more efficiently in a desired orientation. The interior of the snow guard tubes can be selectively coated with infrared absorbing or reflective material to direct the heat in a desired orientation when infrared LEDs are used as a heat source. The snow guard can be attached to many types of roof surfaces including tile roofs, metal roofs with or without standing seams, and shingle roofs.

A geothermal heat delivery system supplies geothermal heat for various residential, surface heating applications, including heating driveways, paths, sidewalks, homes, roofs, swimming pools, and commercial applications, including heating roadways, parkways, highways, airport runways, parking lots and sidewalks. The geothermal heat delivery system includes a series of heat pipes that are used to provide geothermal heat from a borehole to a structure or a surface, which can for example, melt precipitation on a road, driveway or roof, without the use of a ground source heat pump.

In some aspects, deicer systems to distribute a deicing fluid along a roof of a building to limit ice dam formation can include: a pre-pressurized water source that provides pressurized water; a deicer solution source containing a deicer solution; a passive mixing system in fluid communication with the pre-pressurized water source and the deicer solution source, the passive mixing system being configured to combine the pressurized water and the deicer solution to form a deicer fluid; and one or more emitters configured to be disposed along the roof, the emitters being in fluid communication with the passive mixing system to receive the deicer fluid and dispense the deicer fluid along the roof. In addition, certain systems described herein can be run with an electric pump.

A clip may include a first vertical wall having a first lower edge. A clip may include a second vertical wall having a second lower edge. A clip may include a top wall joining the first and second vertical walls and creating a gap therebetween. A clip may include a routing clamp extending outwardly from each of the first and second lower edges, the routing clamp including: a lower guide, an upper guide, a bendable member joining the lower and upper guides and can be bent over a heating cable such that the heating cable is trapped between the upper guide, the lower guide, the bendable member and one of the first and second vertical walls.

A charge control system includes: a charging apparatus including a first processor to cause the charging apparatus to store electric power to be supplied to a preset region; a facility group installed in the region, to be supplied with electric power from the charging apparatus, and including a second processor; and a charge control device including a third processor configured to predict a snowfall amount in the region, calculate a snow removal electric power amount for removing snow covering the facility group based on the predicted snowfall amount, and perform charge control for causing the charging apparatus to store electric power equal to or more than the calculated snow removal electric power amount.

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 method may include obtaining first ambient condition data corresponding to a first building in a first location. The method may further include obtaining a set of ice dam models. The method may further include predicting, based at least in part on the set of ice dam models, an ice dam formation on the first building. The method may further include obtaining a heating profile. The heating profile may be based at least in part on the first ambient condition data. The method may further include adjusting, based on the heating profile, a heating device of the first building.

The present disclosure provides a heating device for the removal and/or prevention of ice masses or snow. The heating device can include a heating cable formed in a pattern of loops, arcs, or other shapes. Power can be applied to the heating cable and, when placed on top of an ice mass or within a concrete or asphalt surface, the heating device can melt the ice mass or snow.
