Monocrystalline silicon photovoltaic tiles

Our solar tiles are manufactured with the highest quality PERC monocrystalline photovoltaic cells to maximize the efficiency of your roof. SunStyle ® is a structural roof and solar module combined, providing a durable, leak-proof roofing solution that is both beautiful and protective.

Crystalline Si includes monocrystalline silicon and polycrystalline silicon, and the efficiency of monocrystalline silicon cells is higher. The last three types of materials are commonly used in thin-film solar cells. They usually have a positive-intrinsic-negative (p-i-n) layer structure, which is coated with a transparent conducting oxide (TCO).

The photovoltaic cells are often made from thin-film cells to maintain the flexibility in the foil and the efficiency regarding high temperatures for use on non-ventilated roof solutions. Unfortunately, there are few producers in the market that provide weather tight solutions.

Conventional monocrystalline silicon cells can operate efficiently at lower concentrations (1–100 sun) without needing active cooling mechanisms. Low concentration systems generally feature wider acceptance angles, and in some cases do not need to track the sun, reducing their cost.

Organic solar cells are another class of thin-film solar cells. According to the photovoltaic effect, organic solar cells generate a voltage using a semiconductor material with photosensitive properties.

When investing in high-quality solar cells, it is desirable to integrate them with systems that achieve very high concentrations.
