The Solar Module for Balconies and Terraces

FREDDY hangs around and turns sunlight into electricity. This ultra-lightweight high efficiency solar module is ideal for small spaces like balconies and terraces. Hang FREDDY onto railings or walls and generate your own power from sunlight quickly and easily.

How FREDDY works


FREDDY converts sunlight into large amounts of direct current (DC)


The inverter transforms solar power to home electricity


Solar power from FREDDY mixes with the public grid and reduces energy costs.

Solar module for the balcony

Solar cells have been used for calculators and satellites for decades. Usually solar modules were installed on roofs permanently. With FREDDY you generate your own electricity on balconies and terraces. When sunlight hits one FREDDY then power up to 70 watts is generated. Install up to 4 FREDDYs to get a total output of up to 280 watts.

Connect FREDDY to your home network

The inverter transforms the solar electricity from FREDDY into normal alternating current (AC) for the home network. The inverter monitors the public grid and stabilizes it. Our inverter is connected to a regular power socket with a normal plug for home use. When the inverter is unplugged it switches off within a few milliseconds to protect you from electricity. This redundant safety shutdown technology is certified and safe for more than 10 years.

Solar power saves on the energy bill

The electricity from FREDDY mixes with the electricity from the public grid. Electricity always takes the shortest path. The electricity flows directly to the devices plugged in at home. Now you need less power from the public grid. With FREDDY you save energy costs and generate your own power.

With FREDDY you can not only save energy costs. How will our energy system look like in the future? The fossil energy system leads us to a dead end. Let’s take new paths!

If every home in Europe uses only one FREDDY we can turn off 3 nuclear power plants or 6 coal power plants. Let’s go solar!


FREDDY is easy to install and ready for use in only a few moments. FREDDY is 80% lighter than a conventional solar module and can be conveniently fixed by using metal eyelets. With regular plugs you connect FREDDY to the power grid and generate your own electricity.


For FREDDY we use Sunpower® solar cells which break all records in efficiency tests. With our special cell interconnection that minimizes transmission losses more energy flows from FREDDY to the inverter than from other solar modules. The specially structured surface of FREDDY catches sunlight better and reflects less. With all this efficiency you generate a lot of power even on small surfaces.


The DC voltage from a FREDDY is completely safe for humans. We use the inverter AE Conversion INV-315-50 made in Germany to feed into the home power grid. AE Conversion has been setting standards for reliability, safety and compliance for years. The inverter feeds operates for years with minimal losses. AE Conversion’s power grid monitoring system detects unplugging and switches off the inverter in a few milliseconds.

Backup Power Blackout Offgrid

Use FREDDY together with the SolCube power generator. Then you will generate your own power even when there is no public grid or sunshine available.

Frequently Asked Questions (FAQ)

Already purchased a FREDDY balcony set and looking for the manual?

Up to 4 FREDDYs can be connected to 1 inverter. ATTENTION: FREDDYs must never be connected together directly! To connect several FREDDYs to one inverter use an MC4 parallel adapter.

You no longer need to get the power you generate yourself from the public grid. This slows down the energy consumption and the power meter also slows down or even stops.

FREDDY is so easy to use that absolutely anyone without any technical knowledge can hang FREDDY and plug it in. If help is needed anyway, we are sure to find a solution.

The more direct sunlight hits FREDDY, the more electricity it generates. Even on cloudy days you can still generate a little electricity with FREDDY. Thanks to many years of weather data, solar radiation can be precisely forecasted throughout the year.

Hang FREDDY completely in direct sunlight to get the most out of it. Inside FREDDY the solar cells are connected together in series in one string. This means that electricity generation drops significantly even when FREDDY is only partially shaded.

FREDDY is built in protection class IP65. It has complete protection against human contact. Dust cannot penetrate and FREDDY is protected against water from any direction. FREDDY can hang outdoors all year long.

FREDDY is a semi-flexible solar module and can be bent a little. Under no circumstances should FREDDY be kinked, otherwise the solar cells will break.

FREDDY comes with a warranty of 5 years and the AE Conversion inverter comes with a warranty of 10 years.
