According to data recently released by the German Solar Industry Association BSW-Solar, in 2024, Germany added a total of 1.05 million PV systems, of which 435,000 were balcony PV systems. This means that at least 2 out of every 5 PV systems were balcony PV systems. Installed capacity grew by 100%, with a growth rate far exceeding that of other PV types. This rapid growth is attributed to the pressure of persistently high electricity prices in Europe.

Taking Germany as an example, residential electricity costs in the second half of 2023 reached 0.4162 euros per kilowatt-hour (including taxes and fees), ranking among the highest in the EU. Against this backdrop, the economic advantages of balcony PV are significant: a complete basic system package starts at just 600 euros (approximately 900 USD dollars); a typical configuration of two 500W modules generates an average of 5 kWh per day and an annual electricity generation of 1500 kWh. Calculating based on Germany's electricity cost of approximately 42 euro cents (0.4162 euros) per kilowatt-hour, a balcony PV system can save 228.91 euros per year. At this rate, it can essentially pay for itself and become profitable within a few years.


With the growing adoption of distributed PV, energy loss in off-grid systems and instability in grid-tied systems have become pain points in the development of the PV industry. CNCOB has innovated on its microinverter technology, launching a micro-energy storage inverter system which can convert and store surplus power from the PV system, releasing energy during peak demand, thereby improving the energy utilization efficiency of distributed PV systems. It also provides timely supplemental power when the grid experiences fluctuations or failures, ensuring the continuity and reliability of power supply and enhancing the stability of distributed PV's grid integration. This technology is a major breakthrough in the field of PV energy storage and a milestone in distributed energy management technology.

A PV Rapid Shut Down (RSD) device is installed at PV modules and can quickly cut off high-voltage DC electricity from them, ensuring the safety of the PV system and maintenance personnel. The rapid shut down device developed by CNCOB is one of the few products globally that holds key patents for rapid shutdown technology. The product offers high safety, compliant with US safety standards NEC690-2017/2020. Its unique bidirectional communication function enables module-level fault monitoring and diagnosis, as well as automatic high-temperature warnings, and it is compatible with various communication protocol devices, combining both economic efficiency and high safety. To meet more user demands, CNCOB has released updated versions of its RSD products, with a maximum input current of up to 20A and featuring a metal casing for enhanced safety.
