Photovoltaik INSELANLAGE

- from 360 Watt
- Solar Battery 


A basic distinction is made between mobile and fixed off-grid solar systems.
+ Stores solar or low-cost (off-peak) electricity
+ Completely independent of the public grid
+ No power cuts due to UPS function (uninterruptible power supply)
+ No power fluctuations
+ Capacity of the house power system is self-determined
+ Independence from fluctuating conditions and electricity prices
+ Better ability to plan amortisation
+ Amortised in max. 10 years
- More space required for the batteries
- Higher purchase costs
- No connected to the public grid so no is possible use additional energy from the public grid
Each island system is planned individually for you, taking all factors into account and using the latest technology. We look forward to your contact!

Island solar system solar energy

Example system 3kW solar modules and 5kWh solar battery storage

And here are details about the system, its performance and the technical material. The solar modules convert solar energy into electrical energy. This electrical direct current is then converted in the inverter into the 230V or 400V usual in the household. Furthermore, this inverter provides the electric current for self-consumption. The electrical energy that is produced more than is currently used is used to charge the batteries and cannot be fed into the public grid.
The advantages of this type of system are that the entire power system becomes less dependent on power fluctuations and outages. This type of system is absolutely autarkic.
The example system is optimal for a family with an average consumption of approx. 20 kWh per day. 

Step 1

We plan with you the ideal solution for a system with solar modules and solar batteries as a island system
It does not matter if it is for your house, your company or your hotel, we will find the best solution for you! However, all important factors must be taken into consideration so that the solar system is a real success.The planning must be especially thorough otherwise the energy will not be sufficient at the end of the day.
With the batteries, it is important to consider all factors and wishes. You have to know exactly what you want to storage by the battery.
In the example, a consumption of approx. 15-20kW per day, south orientation of the roof. 230V line goes into the house. The system must be planned so that it is sufficient for the house and the family.

Step 2
Determine the solar modules of the battery storage and the accessories
Solar Anlage für Eigenkonsum mit ca. 3 kW Solarmodulen und 5kWh Speicher bestehend aus: 
• 8 solar modules aprox. 390 W up to 25 years warranty
European company
• Storage 5kWh with 6000 charging cycles so that a buffer is available
• Inverter for island operation
• Aluminium profiles for professional mounting
• Alternatively aluminium profiles flat roof o floor mounting
• Cables for the connection of the solar modules
• Electrical material for the batteries
•  Electrical material  for the house electric 
• Cables for the alternating current range but no connection to the public grid


Step 3
There are many factors to consider when installing a solar system so that you can enjoy it for many years.
We use the highest quality materials for mounting the solar system so that you can really benefit from the system for up to 25 years and more.
We always attach great importance to professional mounting, taking into consideration today's technical possibilities.
The same applies of course to the inverter, which is well suited for stand-alone operation and everything on the 220V side.
batteries with a usable capacity of up to 90% and up to 6000 charging cycles.

Step 4
Finished off-grid system with readjustment and installation
With a readjustment, the performance of the system is optimised so that the system is fully utilised and there is always a reserve, which is not to be neglected!
Adjustment to the new technology is inevitable.
How does my system pay off?
This is an off-grid system - solar system kit 3kWh solar modules approx. 5 kWh battery storage.
Self-determination of the capacity of the power system
No power fluctuations and power cuts with sufficient capacity
8 solar modules with 25 years warranty
1 Island inverter with 10 years warranty
2 Lithium battery storage approx. 5kWh with guaranteed 6000 charging cycles 18 years warranty
Complete installation with all materials.
Approx. 7000 Euro

Step 5
Profitability calculation
Solar island system - you determine the capacity!
No power cuts and power fluctuations with sufficient capacity.
The off-grid system can always be expanded.
1800 hours of sunshine with 3 kW per hour 5400 kWh
Minimum standard electricity price per kilowatt of 0,13€.
Total profit per year of at least 702€.
Even if electricity prices do not rise, the solar system is paid for in 10 years, even if electricity prices remain the same and the solar system lasts at least 25 years, the total return on investment is approx. 9% over the lifetime of the system, even if electricity prices do not rise.
electricity prices do not rise. Living with electricity without CO² emissions.
