Autarq system components: How does it work?

The Autarq system.

How it all comes together.

How do solar tiles on your roof provide electricity in your sockets? Learn about the components of an Autarq solar roof tile system and discover how they work together.

System components

Autarq solar roof tile systems are modular: They adapt to your energy needs and the conditions of your roof. To get the most out of your Autarq solar roof, we recommend these system components.

System component

Autarq solar soof tiles


Each solar roof tile generates up to 8 kWh of solar power per year. Once you have decided how much electricity you consume, you know how many tiles you need. An Autarq-certified roofer installs your solar roof tiles just like regular tiles.

System component

Autarq wire harness


The backbone of an Autarq system: the wire harness, which is installed on the roof by an Autarq-certified expert prior to the roof tile installation. It takes the roofer only 15 seconds to plug the cable at the back of each solar roof tile into the wire harness.

System component

Autarq PV converter


Transforms the DC voltage generated by a low voltage photovoltaic field (60-120 VDC) into the input voltage for standard solar inverters (200-450 VDC). The electrician installs it near the roof and puts it into operation.

System component

Autarq Monitoring App


Our monitoring app provides Autarq solar roof owners with a graphical representation of their solar power yields. This makes it easy to monitor how much energy your solar roof is generating every quarter of an hour.


Standard solar inverter


All photovoltaic systems generate direct current (DC). But the electricity grid operates on alternating current (AC). A standard solar inverter makes your solar power grid-compatible. It’s indispensable for every solar system.




With a home charging station you can charge your electric car safely and fast. The best thing about it: If you’re not driving your car during the day, its battery can store up to 100 kWh of solar power.


Battery Storage


With a battery storage system, part of the electricity generated during the day can be temporarily stored to be used in the evening or at night. This reduces the amount of electricity drawn from the grid to a minimum.

Smart meter


An intelligent metering system – also known as a smart meter – consists of two elements: a digital electricity meter and a communication module that enables data transmission to the electricity provider and distribution network operator.

Got any questions?

We've got the answers.

No. An Autarq solar roof tile is approx. 700-800 g heavier than a conventional roof tile, so compared to a normal roof covering there is an additional, distributed load of approx. 10 kg per square metre. This additional load does not normally pose a problem for the statics. Autarq solar roof tiles also fit seamlessly into familiar processes, requirements and dimensions. There are no special requirements to consider.

Much like traditional photovoltaics, a roof orientation to the east, south and west is best suited for an Autarq solar roof. Roofs facing east and west should not exceed a roof pitch of 45° in order to get as many hours of sunlight as possible. Since solar roofs are nowadays installed primarily to generate electricity for self-consumption – and not to feed power into the public grid – using an east or west-facing roof has a decisive advantage: the distribution of power generation throughout the day is much more even than with a south-facing roof. Although the latter achieves a high yield peak at midday, most residents have little need for electricity at this time of day. With a particularly low roof pitch, even a north-facing roof can be covered with Autarq solar roof tiles.

Currently, we cooperate with the roof tile manufacturers CREATON, Jacobi-Walther and Skarpnes.

With the performance data of the 2022 solar roof tiles (10 watts per tile), the Autarq system achieves 120 watts per square metre.

As a rule of thumb, 12 solar roof tiles are installed per square metre.
