Roof areas for the generation of energy

It does not matter to south, west, east or even a little bit towards north. Each roof surface, each partway sunny facade is urgent necessary for the generation of energy.

7500 kWh electric power per year and inhabitant is typical for high industrialised countires. Some consume can bei optimized, but on the other side, new consume by plug-in hybrid cars. This can be calculated like this:
  • 1 car for 2 people
  • 16,000 km per year, 15 kWh for 100km electric power
  • 80% of all travels electric
Makes 1920 kWh per car or 960 kWh per inhabitant. So 80% electric traffic is an additional consume, which can be compensated by more efficient electric power usage in other areas. But this all should be produced in the future with sun, wind, the existing water power plants and biomass.

  Alibi solar collector is not enough

This quantity estimation shows: The alibi solar collector on the roof, like a flag to show green convincing, is not enough. Also a roof with solar collectros is not enough. Even a roof with photovoltaic is still not enough.

  Electric power, heat and climate regulation

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

Photovoltaic - Electric power direct from light Photovoltaic - Electric power direct from light
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.

Photovoltaic roof integration Photovoltaic roof integration
Reduce costs by photovoltaic roof integration instead of making the roof and all the photovoltaic seperat with much more work time.

Plan for house building - requirements specifications Plan for house building - requirements specifications
From the first idea over the requirements specifications and how this develops to constructions plans. The development of my second plus energy house.

Roof for a one family house
Planning for the roof, the deciding component, which makes a house an energy waster or energy producer. Electric power and warmth from the roof is a must.
