Plan to save energy bills ? Use "'Polysolar’s technology""
The PV arrays produce electricity and serve as a daylighting design element.
Photovoltaics (PV) is a means of producing electricity on site, directly from the sun, without concern for energy supply or environmental harm.
These solid-state devices simply make electricity out of sunlight, silently with no maintenance, no pollution, and no depletion of materials.
A Building Integrated Photovoltaics (BIPV) system consists of integrating photovoltaics modules into the building envelope, such as the roof or the facade. By simultaneously serving as building envelope material and power generator, BIPV systems can provide savings in materials and electricity costs, reduce use of fossil fuels and emission of ozone depleting gases, and add architectural interest to the building.
A complete BIPV system includes:
The PV modules (which might be thin-film or crystalline, transparent, semi-transparent, or opaque);
A charge controller, to regulate the power into and out of the battery storage bank (in stand-alone systems);
A power storage system, generally comprised of the utility grid in utility-interactive systems or, a number of batteries in stand-alone systems;
Power conversion equipment including an inverter to convert the PV modules' DC output to AC compatible with the utility grid;
Backup power supplies such as diesel generators (optional-typically employed in stand-alone systems); and
Appropriate support and mounting hardware, wiring, and safety disconnects.
This photo shows how the PV panels are angled to capture the sunlight shining on the roof.
BIPV systems can either be interfaced with the available utility grid or they may be designed as stand-alone, off-grid systems. The benefits of power production at the point of use include savings to the utility in the losses associated with transmission and distribution (known as 'grid support'), and savings to the consumer through lower electric bills because of peak shaving (matching peak production with periods of peak demand). Moreover, buildings that produce power using renewable energy sources reduce the demands on traditional utility generators, often reducing the overall emissions of climate-change gasses.
