Island systems

Island systems

Historically, photovoltaic modules have found their first economic applications in island systems. Everywhere where the public grid is missing but electrical energy is needed photovoltaic power can be the better technical and economic solution. Here, solar power does not need to compete against the usually cheap price for fossil generated electricity from the grid, but can often beat the cost of alternatives such as diesel generators or small wind turbines.

Possible areas of application are e.g. the supply of country resorts, fincas, relays stations, signal devices, mountain huts or holiday retreats without connection to the public grid.

The installation of a photovoltaic system will save you money. And your nerves, as the solar system will emit neither noise or fumes, nor do you have to remember to fill up the diesel tank in time.
Certain countries even offer subsidies and cheap loan programmes for such installations, e.g. Spain.

The design of island systems is complex and requires a lot of know how and expertise. Different to grid connected systems the plant itself must be able to react safely to the different load requirements respectively to deliver the requested electricity in total. High attention is to be paid to the exact approximation of the load pattern for today and also as exact as possible for the future. And this not only with respect to the total demand per time unit, but also with regards to the load peaks and their occurrence against the solar energy supply.

As a result, a multitude of systems is feasible, be it with or without batteries, with or without AC converter, with or without backup via motor operated generator or even a wind turbine. By means of investigations, calculations and simulations we will propose to you the technical and economic optimum out of all options possible and work out a detailed solution. Of course we will supply, install and commission the chosen system and we can also offer regular maintenance works as well as emergency services.

We believe in integrated solutions. Therefore, the first thing we do is to consult with you how the electricity demand can be reduced for your island grid. Then the system can be designed smaller and cheaper. For example the exchange of the lighting system or the replacement of an older refrigerator with a more efficient one could be a very cost efficient solution.

If you do not want to dispense with the comfort of electrical energy, but wish to enjoy the unspoilt tranquillity of your secluded hideaway, e.g. your Spanish finca, then we are there to advise you on the possibilities of a solar powered island supply system.
