Solar cells become the highest mode. A growing number of Swedish homeowners are installing solar panels on their homes and, for the moment, this is happening on the "sunny side". Until now, the installation of solar cells is most common in new construction or major renovations of more modern public buildings.
But most of the most respectful roofs of solar energy are on real estate built before 1945. These houses also represent a quarter of energy consumption.
New solar cells
Mounting solar panels in an old house can be a big problem. As a result, more and more owners of old homes are interested in solar cells.
To meet the demand, the development of new solar panels is underway. Solar systems, for the manufacture of soles on the facades of houses and tents, are in progress. Like solar cells whose appearance is adapted to buildings considered until now as historically sensitive.
Save insoles in pioneering research
The fact that the development is currently very sunny is not a coincidence. One of the major problems of solar energy is so far the difficulty of storing it, which has made the sun a distinctive fresh product. But now, a research team is looking at Chalmers University of Technology to do it.
With a specially designed molecule capable of storing energy in a liquid, researchers strive to develop a system to store the soleplate for 18 years.
The research is revolutionary.
"Cheap and totally renewable"
The system not only allows us in the northern hemisphere to save energy from the sun from summer to the dark winter period. It is also totally free of emissions.
"The goal is to cost less than batteries and to have a fully renewable energy," said Kasper Moth-Poulsen, research director, assistant professor in nanomaterials chemistry at Chalmers, Gothenburg, the scientific radio.
Developed for district heating
Promising trials with the new molecule have already been done. Researchers are now working to make the use of technology possible in larger systems for district heating, for example.
If all goes as planned, the new technology will be available commercially in 10-15 years.
Then, it will probably be possible for most homeowners in the country to know easily if their roof is suitable for the soles. A new map template, being prepared at the University of Uppsala, should make this possible. Particularly useful, it is hoped that it will be in areas with much older buildings.
The tests will be done next summer
"If we then move on to a renewable energy system, it is important to also examine these old buildings and determine how they can contribute to this conversion," said David Lingfors, researcher at SVT News East.
The new mapping tool is currently being tested in the Stockholm urban area, in the sensitive architectural environment of the Visby culture and in Halland, where the appearance of the houses varies considerably.
The evaluation of the map project will take place next summer.
