Power outage in Münsterland

Intense snowfall broke the high voltage pylons ans with this the power supply. for several days. What would have brought a photovoltaic in this situation.

  Grid connected PV is no emergency power supply

A grid connected photovoltaic equipment delivers only power when the grid is on. When a service technican switches off, he depends on, that the grid is really switched off. It has to be impossible, that a photovoltaic delivers power to the wire just under repair.

So a photovoltaic equipment has to be special designed to be also an emergency power supply. An example for this was on the Intersolar fair zu sehen

Normally a net-coupled photovoltaic equipment switches off immediately if the net has no tension. Protection for electrical engineers maybe just repairing the grid.

  Design of the memergency power supply

After the photovoltaic and a equipment for emergency power supply, the next question is the size. To cook electric after a power failure because of a snow strom would be a big luxury. With the question what functions should be supported during a power failure comes the question to switch off big power users, to preserve only basic comfort for a longer power failure.

An other reason for a house control system. Power failure on a sunny day, the photovoltaic delivers 8 kW, no problem for electric cooking. Same situation on a cloudy December day, the electric cooker is switched off by the house controll system.

Different view points about photovoltaic from our different technical magazines as wide outstretched information about electric power from light.

  2005 real estates and mobility

The demand for future secure real estate increases. From the simple roof over the head, operating expenses do not matter because energy is cheap, to self supply with heat and electric power.

Peak Oil: Mobility shall be independent from oil price
Commuters with daily 100 kms for the way to the work observe anxiously the oil price: How long is the way to the work still performable? What remains, after refuelling?

House to sell in Haidenrain near Radkersburg
Zero energy house with negative operating expenses with 260 m² living space to sell 1000 ms ² property because of a move caused by the family for about only 280,000 EUR.

Cheap energy creates cheap botch-up
The mainstream of the mass media laments the rising energy prices. However, a precise situation analysis reveals: cheap energy leads to botch-up solutions making sick.

Cheap electric power for unprofessional solutions Cheap electric power for unprofessional solutions
An omnipresent sight in southern lands. The back chill unity of an air-conditioning stands on a terrace and makes noise with the ventilating fan.

Out of oil, gas and wood
The gas price is coupled in the oil price. But the consumers will soon see that also the wood price is coupled to the oil price. Only solar energy makes really independent.

Franz Alt! 18 degrees.No! Thanks!
Franz Alt propagates 18 instead of 24 degrees of ambient temperature, however, there is nothing more superfluous than to freeze at 18 degrees in a solar house with an electric power and warmth combination system.

Building Tower to Babel: huge upward wind power stations
EnviroMission would like to build with huge scenery consumption an up wind power plant. However, the electric power yield is in proportion to the surface demand very small.

Electric power and warmth from biomass
The design of the equipment will strongly change during the next 20 years. At the moment such equipment are construed as constantly running run power stations.
