Power outages precautions

What helps a grid connected photovoltaic at a power outage? Tips for a photovoltaic helping over a power outage liks in Münsterland.

Endurance for the emergency power supply

The typical emergency power supply for an one family house would be designed for one day without electric power at a restricted comfort level. No electric cooking, festive lighting and other big power users. At an plus energy house should be 3 kWh for one day enough. At a longer power outage, the photovoltaic makes the system more endure.

A 10kW photovoltaic can deliver at an sunny summer day about 60 kWh. But how much at a December day with snowfall and dense clouds? A weather such like in Münsterland as the grid power failed.

Photovoltaic compare
A 20 Watt crystalline silicon photovoltaic from 1998 vs 3 layer amorphous from Uni-Solar. Under dense clouds, the crystalline PV has no chance.

Extrem difference at dense clouds

Even in the area yield is the triple amorphus cell bettern than my crystalline photovoltaic from 1988. At subjectively the same dense clouds on a December day, the yield from a day can be 0,1 to 0,5 of peak performance. A plus energy house with some batteries is even under this conditions self-support. It's only not possible to cook a banquet with 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
	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.

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.
