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.
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.
