Island's Off-Grid Solar Plant: Completely Powered by Solar Panels Ensuring True Self-sufficiency
In the pursuit of energy independence and cost savings, homeowners are increasingly turning to solar power. Two popular options are grid-tied systems and hybrid systems, each with its unique advantages and disadvantages.
A grid-tied photovoltaic (PV) system, commonly used for single-family homes, operates by harnessing solar energy during the day, using it as needed, and sending excess power to the utility grid. The system is essentially the same as a grid-connected system without battery storage. While these systems offer lower upfront costs and simplicity, they are less independent and self-sufficient. They rely on a stable grid supply, shutting off during power outages for safety reasons, and provide no backup power during blackouts.
On the other hand, hybrid systems, which include battery storage, offer increased independence and self-sufficiency. These systems provide backup power during grid outages, allow greater use of self-generated solar power, and reduce reliance on grid electricity. They are particularly beneficial in areas with unstable grids or no net metering, as they help maximize savings in the long run.
One example of a cost-effective hybrid system is the Trina 10.5 kWp off-grid system, priced at 5,100 Euro, with shipping costing 129 Euro. This system includes 24 bifacial solar modules, a Growatt battery, two off-grid inverters, and a Growatt monitoring device. The Growatt AXE 5.0L-C1 battery used in Trina off-grid systems can be retrofitted to up to 25 kWh, allowing the storage capacity to grow with energy demand.
For those who prefer a do-it-yourself approach, Trina also offers DIY off-grid solar kits in various sizes. Prices for these kits range from 3,425 Euro to 5,525 Euro, inclusive of shipping costs (waived for self-collection in Karlsruhe).
It's essential to weigh the costs, benefits, and energy needs when deciding between a grid-tied and a hybrid system. While a grid-tied system is cost-effective and simple, it offers limited independence and self-sufficiency. To gain greater autonomy from the grid and maximize savings, a hybrid grid-connected system with battery storage is advantageous.
It's also worth noting that solar technology in Germany enjoys a zero tax rate, while the subsidy has been abolished in Austria as of March 31, 2025.
In conclusion, the choice between a grid-tied and a hybrid system depends on individual energy needs, budget, and the level of independence desired.
