using the combination of traditional roof cladding and solar voltaics, the ‘SolTech‘ solution from the swedish energy company implements glass tiles on top of highly efficient, mono crystalline solar panels to generate electricity. protected from damage and theft, the strategic installation harnesses power from the sun, and captures the accumulated charge with the buildings existing heating system, usually through a storage tank. as a result, the system can provide hot water and heating for the majority of the year.

 specially designed absorbers are installed into the glass roof tiles, through which fluids circulate. covered by a polycarbonate enclosure, the absorbers are placed on an insulating layer to prevents heat and loss.



solar cells are integrated underneath the glass roof tiles – the solar electric system has a output of 1 kWp



the glass roof tiles are made of high transparency glass with a low level of iron oxide. the installation uses a double-S profiled tile very similar to traditional concrete tiles used in nordic and other countries.



the entire roof surface is covered with SolTech glass roof tiles

  • The glass tiles are a really nice idea and it would be nice to see them used for other purposes than hiding solar panels, e.g. a whole skylight roof… The problem I find with these images posted is that they look really ugly when used with the contrasting redbrick tiles! Also just out of curiosity whats the function of the small fence at the bottom of each roof with these tiles?
    But all in all a pretty cool idea!

  • the glass tiles are o.k. in themselves. but having spent a load of money on solar panels (a good thing), why spend a whole load more on some glass tiles that can only downgrade the performance of the solar panels. what next, glass rod thatch; or dark tinted glass slates…?

  • @ sandy: the fences are for snow. this is pretty much standard for all of northern europe.

    michael says:
  • These tiles look by far more better than flat panels, if you have to preserve an old buildings appearance. Sometimes you MUST do this by law. It’s only that they will cost some efficiency and make maintance a lot more difficult.
    The fence is against sliding snow, called roof avalanches. Compulsory in all middle and northern european countries.

  • This system will be a perfect solution if the tiles are tinted in dark or other colours?!.

  • nice design..

  • Nice design……………….

    despina says:
  • Nice post. Roofs are essential part which covers our home. It is best solution for roofs and looks beautiful. Invest in best system
    and it has beneficial to acquire from sunlight. I like these tiles colors and designs of these glass tiles.

  • Design and idea seems like very impressive. Honestly, looks like much better traditional solar panels on the roof. But, I’m curious; some of researchers (who works on global warming and climate) says that, solar panels increasing global warming by “mirror effect” to incoming sun light and turn back to atmosphere. If personal solar panels market grow up and covering roofs, global warm going to be worst they said.

    Any material or technics could be improve in future for reducing mirror effect or already is there any issues under processing?

  • Simply brilliant idea

    Manzoor Ahmad says:
  • I like to suggest Braas PV Premium as a far more attractive system.
