In the ever-evolving world of renewable energy, more homeowners in Germany are turning to photovoltaic (PV) island systems for autonomous energy supply. One such system, the Trina Photovoltaic Off-Grid System, is gaining popularity due to its efficiency and affordability.
The Trina PV off-grid system, available from online retailer ACTEC, comes in various sizes, from 6.6 kWp to 13.2 kWp, with the 10.5 kWp version priced at 5,100 euros. This system includes 24 bifacial solar modules and a battery capable of storing up to 10 kWh of power. For those seeking even more storage, the system can be retrofitted to up to 25 kWh of storage.
Island photovoltaic systems, such as the Trina PV off-grid system, are not connected to the public power grid. However, they can be a practical solution for homes that desire independence from the grid. The main reason for investing in these systems is the independence they offer from the public power grid.
For homeowners who prefer a hybrid approach, zero-feed-in PV systems are another option. These systems can be connected to the grid to draw power if the PV system's performance is not sufficient. Zero-feed-in PVs are popular due to their ability to save time and bureaucracy, as they do not require registration with the tax office or network operator.
ACTEC, a specialist in the delivery of branded photovoltaic systems and balcony power plants, has been highly rated by its customers. As of February 2025, ACTEC has been awarded "good" with 4.06 stars out of 5 from 1,705 reviews on Trusted Shops. The company also offers reasonable shipping costs of 129 euros and German customer service, along with long warranties.
Currently, the purchase costs for these systems vary between 20,000 and 30,000 euros, depending on size and region. However, for those seeking a more affordable option, Solarbringer offers Off-Grid photovoltaic systems for DIY assembly, providing personal off-grid island systems with network support and individual offers for discount prices. Another option includes online complete sets starting at around 3,425 euros from specialized online retailers offering Trina Solar modules with Growatt batteries.
It's important to note that before installing an off-grid PV, electricity consumption should be recorded and evaluated for at least one year to ensure the system's size and battery capacity meet the home's energy needs.
Modern PV complete sets provide everything needed for solar power production and storage, making it easier than ever for homeowners to transition to renewable energy. Whether you choose an off-grid PV system for complete energy independence or a zero-feed-in PV system for a hybrid approach, these systems offer a sustainable and cost-effective solution for your energy needs.
