Kehrer Engineering makes a solar power generation on listed roofscapes possible! The color of photovoltaic modules are namely brick-red, and so fits they optimally in a red roof landscape. The usual shiny blue modules would interfere significantly in many cases - an example is the city of Graz, where the old town of Graz is a UNESCO World Heritage Site.
The red modules have already been approved by German conservationists, eg in Nürnberg.
These red solar panels open up a huge additional potential, even in cities an independent and environmentally friendly power generation to make possible!
This is a further step towards to the use of renewable energies, and allows the increase in energy and resource efficiency.
