Yes, Sunstyle solar shingles each have 2 cables with original MC plugs, with which they are connected in series. In the simple, unshaded cases in long strings, in the case of shading or very small roof areas in short strings on optimizers or micro-inverters. For more details, refer to our article.

With uniform indirect irradiation, solar shingles also produce energy – according to the amount of light. In the case of temporarily shaded areas, optimizers or micro inverters are a good solution to still produce an optimum amount of energy. For very frequently shaded areas, SunStyle recommends its inactive shingles, which match the active ones very well. For further information, read our blog about PV in winter time!

SunStyle tiles use high-performance PERC monocrystalline silicon cells. While standalone solar panels may have slightly higher efficiency per unit, SunStyle tiles cover more roof area, often leading to comparable or greater total energy generation.

Yes, SunStyle tiles are designed to be fully weatherproof. Their interlocking design and overlapping installation ensure maximum protection against rain, snow, wind, and other harsh weather conditions. Each tile forms a watertight barrier, making them suitable for even the most demanding climates.

SunStyle supplies to installers (roofers, carpenters, plumbers or solar installers) who are trained by SunStyle and carry out specialist work. This network of partners can be expanded at any time if you have a preferred installer. Find a professional close to you.

SunStyle shingles are screwed onto vertical solar battens (usually made of wood) with prepared threaded inserts at precise intervals. This setup ensures both a secure attachment and optimal rear ventilation to prevent humidity and overheating.The system includes stainless steel fasteners and gaskets for good durability and high water tightness even at very small tilt angles. For more information, read our installation manual!

SunStyle offers comprehensive technical documentation, installation instructions, drawings with suggestions for edge finishes and roof integration as well as video tutorials.
In addition, every installer installing SunStyle for the first time receives on-site or video-conference construction instruction.

Yes, SunStyle tiles can withstand occasional foot traffic without affecting performance. However, for safety, the glass and the shoes have to be clean and dry, to prevent accidental damage. It’s recommended to step cautiously and consult your installer for best practices.

In cases where standard SunStyle tiles don’t fit perfectly—such as at edges or around obstacles—SunStyle provides cut-to-size inactive tiles. These are trimmed on-site by the installer using tools like circular saws or jigsaws to ensure a precise fit.

The total cost depends on factors such as roof size, complexity, and energy needs. Since SunStyle tiles serve as both a durable roof covering and an energy system, they offer long-term value.
