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 converts direct current (DC) into alternating current (AC) for the home network


Feed into the home network via a socket

Solar module for the balcony

Solar cells have been used for calculators and satellites for decades. Until today, solar modules have usually been installed on roofs permanently. With FREDDY you generate your own electricity now also on balconies and terraces. As soon as sunlight hits FREDDY, it starts generating up to 70 watts. If you need more power, you may hang up to 4 FREDDYs with a total output of up to 280 watts.

Converting power from solar modules to power for your home

The inverter converts the electricity from FREDDY into normal alternating current (AC) for the home network. It monitors the power grid and stabilizes it. With double safety shutdown technology that reacts within milliseconds our inverter is safe to connect to a public grid. This happens for example, when the inverter is unplugged or the grid is switched off for maintenance.

Feed in to the home network

The generated electricity is fed into the home network using a conventional socket. Because electricity always takes the shortest route, it flows directly to the devices plugged in at home. Now you generate electricity yourself and FREDDY slows down the power meter to save you energy costs.

With FREDDY you can not only save energy costs. How will our energy system look like in the future? The fossil energy system leads is 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.

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.

When FREDDY pays off depends on several things. How sunny is the place where FREDDY is hanging? In which direction is FREDDY oriented? How much do you pay for energy? We offer a tool where you can estimate the yield for your location and energy costs. Our tool is based on data from NASA and takes numerous factors into account. Find the tool here.

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.

Conventional solar modules are made of glass. In contrast, FREDDY is made of high-tech plastic. This makes FREDDY easy and safe to use. Inside FREDDY there are wafer-thin solar cells. These fine silicon wafers can break if FREDDY is bent too much. When cracking solar cells FREDDY’s performance drops.

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