Kleines Kraftwerk and Tepto Discount Balcony Solar Kits in Germany

German retailer Kleines Kraftwerk is promoting its Duo BC balcony solar system, a 960‑watt peak (Wp) set that normally costs €569 but is offered to readers for €359. The kit uses back‑contact solar cells that hide busbars on the rear side, promising up to 30 % higher output. It includes a Hoymiles HMS‑800‑2WB 800‑W inverter and optional accessories such as a 5‑m cable and mounting brackets. A larger Quattro‑BC 1.92 kW system is also reduced to €1,819, bundled with an Anker Solix Solarbank 4 Pro storage unit delivering 5.02 kWh.

At the same time, Tepto’s Flex balcony‑solar package provides 800 Wp via four flexible 200‑Wp modules that can bend to a 50 cm radius, allowing installation on curved railings, carports or even motorhomes. The set includes a FoxESS Orbit battery with 2.11 kWh capacity and is priced at €899, €400 less than its usual €1,299 price. Both offers target German homeowners seeking compact, easy‑to‑install renewable energy solutions.
