Photovoltaic Skylight

Photovoltaic skylights not only generate free electricity, but also provide natural light, as well as UV and IR filter.

PHOTOVOLTAIC
SKYLIGHT

Skylights are an ideal application for photovoltaic glass. They are normally well exposed to the sunlight, allowing for optimal energy yield.

PV skylights also improve thermal inner comfort, since most of the UV and infrared radiation are filtered out by the Silicon-based material (solar filter effect). In addition, Air or Argon spacers guarantee the best thermal performance for the application.

 

In other words, PV skylights combine active and passive properties that improve the overall efficiency of the system. Semi-transparent PV glass reduces the need for artificial lighting, generates power, and provides thermal and sound insulation. It also helps delaying interior ageing.

 

SMART BUILDINGS

Photovoltaic skylights not only generate free electricity, but also provide natural light, as well as UV and IR filter.

THE MOST POPULAR PHOTOVOLTAIC SOLUTION

PV skylights are a great solution for both new construction and renovation projects. Novartis Pharmaceutical’s HQ, the American Airlines Arena in Florida, and Bell Works in NJ are some of the projects that chose to integrate a PV skylight manufactured by Onyx Solar.

AVERAGE PAYABACK OF 2 YEARS AND 65% IRR

From a financial point of view, while solar farms rarely exceed a 10% I.R.R., photovoltaic skylights achieve I.R.R. up to 65%. In addition, they offer an average payback time of 2 years, and decrease the energy consumption of the building by a 40%. Considering all these, a PV skylight can generate power at only 0.017 US$/ kWh.

Photovoltaic glass (PV glass) is a technology that enables the conversion of light into electricity. 

To do so, the glass incorporates transparent semiconductor-based photovoltaic cells, which are also known as solar cells. The cells are sandwiched between two sheets of glass. Photovoltaic glass is not perfectly transparent but allows some of the available light through.

 

Buildings using a substantial amount of photovoltaic glass could produce some of their own electricity through the windows. The PV power generated is considered green or clean electricity because its source is renewable and it does not cause pollution. In addition to energy cost savings, potential benefits from the use of photovoltaic glass include reducing the carbon footprint of facilities, contributing to sustainability and consequently, enhancing branding and public relations (PR) efforts.  

In environments where too much heat gets in with light, the reduced transparency can also save on air-conditioning costs. Variations have been designed for environments where more light is desired. For example, Sharp has developed a slitted solar glass product that has gaps between solar cells to enable greater light penetration.

Another company, Onyx Solar, makes photovoltaic glass with a variety of options including different colors, gradient and patterns as well as double or triple-glazed products. Variance in photovoltaic efficiency and light penetration among these products enables multiple options for architectural design.

the Enameled and Tempered glass adopts the silkscreen technology for impressing the high temperature ceramic on the surface of the glass, through the process of baking, solidifying, and then tempering, making the ceramic and the glass combine to a whole one.

There can be complex pattern with various and fadeless color on the enameled and tempered glass. The ceramic after baking does not drop and has great ability of anti-acid and anti-alkali.

The enameled and tempered glass is the tempered glass with great ability of hot impact proof, which is widely applied in the outside-building decoration, and is convenient to control the daylight. It can also be used in the decorating of indoor ceiling, stage floor, partition and so on. There are more choices when it is combined with other kinds of glass.

for Enamels are generally gas-burning flame furnaces which have a sloped bottom and spouts or ladles which allow the ceramic frit to flow off and granulate into fine particles through the water stream and crushing rollers.  Eclats-Enamels.jpg
