With a solar fraction of 78% SECUterm clearly reaches the highest yield.

The solar share of fraction is between 55 and 60 %.

Those involved in the project are also endeavouring to achieve a solar fraction of 50% in Crailsheim.

Up to now a solar fraction of 45% has been achieved.

The solar share of coverage can be increased if the solar energy system also supports room heating.

From March 2012 to February 2013, the solar share of fraction of the local heating system amounted to 51%.

It is only when these are solved that a solar fraction of 50% is realistic.

Even in 2011 direct use of solar energy achieved a solar share of fraction of around 36 per cent.

When the sun is shining, the system achieves a solar coverage share of 100%, and no conventional steam generation is required.

With a solar savings fraction of 51% in the period from March 2012 to February 2013, the solar heating network slightly exceeded the planning goal.

The project is focussing on active and adaptive building envelopes as well as grid-supportive buildings with a high solar fraction.

The concept should decrease the today’s usual extra system costs of solar houses by about 25% while achieving at least the same solar fraction.

With a solar thermal solar fraction of 60% (SAH60), this can be reduced by 105 kWh/(m2UFA·p.a.).

With a solar thermal fraction of 60%, more than 80 kWh per year and square metre of usable floor area are realistic.

The project participants had to harmonise the refurbishment of partially dilapidated buildings with the desire for a high (up to 40%) solar share of fraction.

For example, the researchers varied the solar savings fraction between 50 and 100 per cent, and combined the data with different efficiency house standards.

Diagram 10 shows the attainable coverage rate of a 10 m2 solar energy installation (with 120 m2 of living space in the home) as a function of the state of the building structure (partly expressed using the abbreviations of the corresponding building or construction regulations).

Using newly developed PVT modules, the aim is to supply household electricity, domestic hot water and space heating with a high solar fraction (0325867A-C).

In accordance with dynamic simulations, the local heating system's solar share of fraction of the annual total heating requirement is between 35% and 40%.

In the area of building heating, research on latent heat storage devices initially concentrated on use in solar heating systems which aim to increase the solar energy share.

Thus, a solar fraction of about 30% is achieved, and more than 95 tons of CO2 per year can be saved.

In order to achieve a solar fraction of 60% with this building standard, home owners can expect additional costs of about two euros per year and square metre of usable floor area in accordance with EnEV.

An example: If a building is built in accordance with efficiency class KfW55 with a solar fraction of 30% (SAH30) and a gas boiler, this enables the specific primary energy demand to be reduced by about 80 kWh/(m2UFA·p.a.) compared with the reference system technology.

The innovative manufacturer of residential buildings in solid construction, HELMA Eigenheimbau AG, develops in close collaboration with the Institut für Solarenergieforschung Hameln (ISFH) a new heat supply concept for solar active houses with solar fractions of more than 50%. Currently, solar houses are usually built with a central buffer storage (typical volumes in dwellings are between 5 and 10 m³), which is charged by the solar thermal system. Hence, the solar heat gained in summer can be partly stored for the heating period.
