A method and apparatus for installing a solar array on the roof of a residence or the like which uses a pan in the installation of the solar modules that make up the array. The pan may also be used as part of the packaging of the solar modules. The pan is comprised of a length of material having a trough-like cross-section. For packaging, shipping inserts are fitted into the trough of each pan. Opposite edges of a solar module are fitted into respective slots in the inserts of two facing pans and a protector is fitted over each end thereof to form a package for shipping. Once on site, the packages are disassembled, the pans are mounted on the roof, and the modules are connected to the pans to form the array.

Installing a solar panel on a roof

A system and method for installing a solar module on a roof using a mounting structure which can be adjusted after it has been fixed to the roof. The mounting structure is comprised of a plate having a slot into which an adjustable bracket is slidably positioned. The mounting structures are spaced from each other and the plates are fixed to the roof by toggle bolts or the like. A framed module is placed across the structures and one or both of the adjustable brackets are adjusted to align holes in the frame of the module with threaded chambers in the brackets. Next, threaded fasteners are passed through the holes and into the chambers to thereby secure the solar module to the roof.

System for mounting a solar module on a roof or the like and method of installing

A method and apparatus is disclosed for monitoring the performance of a solar powered electrical supply where the supply comprises an array of photovoltaic cells that are mounted on a building. In one embodiment, the apparatus comprises: a device for producing a signal representative of solar irradiance; circuitry for computing a running performance signal by using at least the irradiance signal and a measure of the electrical power supplied to the load from the array; a radio for broadcasting the performance signal; and a portable unit for receiving the performance signal from the radio and for visually displaying the performance signal, power production, and electrical utility usage.
