The German manufacturer Autarq sells its solar tiles at a price of between 25 and 30 euros per piece. He claims that a photovoltaic system built with his tiles can cover around 70% of the needs of a conventional German house.
German solar manufacturer Autarq has announced that it will increase capacity at its solar tile manufacturing plant in the eastern German city of Prenzlau, where production began in 2018.
The company reports that its products have already been used on 205 roofs in Germany.
Projects vary in size from 5 to 8 kW.
The price for customers varies between 25 and 30 euros per tile. According to Autarq, a roof that incorporates its monocrystalline solar tiles can cover up to 70% of the electricity needs of a single-family home.
Each tile has a power of 10 to 12.5 W, depending on the size, and a power density of 127 to 135 W per square meter.
According to the company, a 5 kW installation would require around 500 tiles for a total area of around 40 m².
Visually, the photovoltaic tiles are barely distinguishable from the original tiles. There are also no weight differences, so the statics of the roof are not affected, according to the manufacturer.
The company also claims that the tile and the photovoltaic block are connected to form a robust component, so that the flow of water and the tightness of the roofs are preserved. The cables and plug contacts are located under the roof lining and are thus protected against the weather.
Autarq also specifies that a PV system built with its tile is insensitive to shading due to parallel connection.
Skylights, chimneys, ventilation ducts or antennas also do not influence the installation and efficient operation of the systems.
Installation process:
The tiles are guaranteed for 25 years.
