Solar cell in any case

The 75% of the demanded electricity will be made by the solar cells with network regeneration. When there is no consumption the solar cells recharge electricity to the network directly which is measured by an individual meter. If the solar cells don't produce electricity (at night), then we can use the traditional electricity network.

As we suspected, the isolated system which means a separate power supply, has a reason of existence only where isn't any network available.

With a relatively cheap aggregator we can assure that in case of a little powerbreak the most important consumptives will work.

In the course of electric planning we have to refine the probable electricity demand and the energy amount served by the solar cells. We didn't calculated with a bigger capacity system, because the cells require a relatively big space and it is not sure that it will fit on the roof. The solar cells will be placed on the flat roof and on the parapet walls of the south facade.
