A photovoltaic shingle that perfectly integrates with shingle roofs Photovoltaic shingles
Tegosolar® is a photovoltaic shingle with the advantages of normal shingles, with which it integrates perfectly. Tegosolar offers high architectural standards in many settings where it would be “impossible” to fit traditional photovoltaic panels.
Tegosolar®’s various traits – namely its slim design, flexibility and light weight – make it a winning choice for many roof types, both on new builds and renovations, on buildings for residential, commercial and public use, as well as on industrial buildings.
The photovoltaic cells produce electricity
The Tegosolar® photovoltaic cells are made of triple-junction thin-film amorphous silicon: each cell absorbs the blue, green and red light in the solar spectrum through its 3 separate layers.
In this way, the PV cells convert a broader spectrum of light into electricity than traditional modules, as they produce energy with direct light as well as in diffused light conditions, namely when the sun is low, when the sky is cloudy and when cells are installed where orientation and angle are less than optimal.
Advantages
- flexible, able to follow the contours of any roof;
- give designers unlimited design freedom for roofs packed with architectural features;
- light, making them easy to transport, simple to install;
- applied flush with the roof, thus avoiding wind loading, a very important factor for static testing of roof structures;
- withstand hail (tested with hail measuring 25 mm in diameter at a velocity of 23 m/s) hence offering long service life;
- do not contain protective glass, an element prone to breakage;
- non-reflective;
- suitable for foot traffic, for quick and easy roof inspection and maintenance;
- self-cleaning thanks to the outer surface produced with ETFE, a special extremely strong, non-stick, anti-glare polymer that allows for optimal sunlight absorption, in addition to having excellent protective qualities that keep the underlying layers safe from weight loading as well as water,
- high output, even where orientation and angle are less than optimal, making them suitable for application on both high- and low-pitch roofs;
- easy to install with mechanical fastening or torched on;
- fitted by waterproofers, thus avoiding the risk of leaks;
The cells
Bypass diodes between the cells allow the module to produce energy even when it is partially in the shade, unlike traditional modules that would lose power from all cells connected in series, and not just from the cell affected by shade. They offer excellent performance at high temperatures, a quality that makes them particularly suitable for roof-mounted applications. They do not require rear ventilation. They have a greater output in kWh of electricity produced per installed Watt (up to 20% more) than many other types of PV module on the market. When they reach the end of their service life, modules are easy to dispose of thanks to the PV Cycle scheme.
