Glass Roofing Tiles Collect Heat To Warm Homes

SolTech Energy, a Swedish company selling solutions for clean solar power, has developed a unique home heating system contained within roofing tiles made out of ordinary transparent glass. The attractive house-warming tiles (somewhat ironically) give roofs a beautiful, icy appearance quite unlike anything else we’ve ever seen before.

In 2009, the SolTech Energy System was selected by a jury and nominated among nine as the year’s “Hottest New Material.” Based on votes by the people, the company’s glass tiles were awarded with a gold medal from the North Building Fair, Nordbygg. “The winning entry combines an attractive design with essential functions for clean and sustainable energy. It is an innovative product that is well in time,“ said the chairman of the jury, PhD. Bengt Toolanen.

So what makes the system so special and award worthy? For starters, the tiles are made from ordinary glass and have about the same weight as those made of clay. Secondly, the system doesn’t, like competitors’ versions, heat up water or vacuum pipes, but clean air. The tiles are installed on top of a black nylon canvas, under which air slots are mounted. The black colour absorbs heat from the sun and the air starts to circulate. The hot air is then used to heat up water, which is connected to the house’s heating system via an accumulator. The beauty of the system is that it cuts energy costs throughout the year, during dark winter days as well as night time, due to its capacity to store heat in the isolating layers of air under the canvas.

UK’s First Solar Farm Built To Float On Reservoir

Berkshire project owners to target water utilities with scheme to cut energy bill

They have become a familiar sight on rooftops and fields across Britain. Now, solar panels are set to start appearing in a new and surprising location: floating on reservoirs.

Britain’s first ever floating solar panel project has just been built in Berkshire, in a scheme its developer claims will act as a blueprint for the technology to be installed at hundreds of sites across the country.

The 800-panel green energy project was installed earlier this month on a reservoir at Sheeplands Farm, a 300-acre soft fruit farm near Wargrave.

The scheme is eligible for renewable electricity subsidies, which are funded by energy bill-payers.

Its owner, Mark Bennett, says that floating panels are even more lucrative than solar farms on fields because no earnings from valuable agricultural land have to be sacrificed to make space for them.
