The SolTech Systems are based on multi-year research at KTH and development here at SolTech Energy. Instead of traditional roof tiles made of concrete or clay, our tiles are made of glass, allowing the sun to shine through onto the absorbing surface underneath. The energy captured is integrated with the building’s existing heating system.
The flexible system
The system is designed for integration with the building’s existing energy solution, regardles of principal heat source. The most common solution is to connect it to a water born heating system via an accumulation tank, but we also offer other solutions.
In northern countries like Scandinavia, the greatest amount of energy is naturallygenerated during the summer but during spring and autumn a considerable amount of energy is also produced. A major advantage of the SolTech System is that it does not need bright sunshine to work, which means that it also generates energy on a day with slight overcast. The best effect is achieved on the roof if it is facing south, but southwest and southeast means only small losses and therefore works fine.
The optimal slope of the roof in northern Europe is 45 degrees, but a good effect is achieved already at 20 degrees inclination. If you have less than 15 degree slope of the roof is recommended wall solution in the glass instead. The optimal slope depends on the latitude of the house, the closer to the Equator you get, the lesser the slope is required.
If you do not need to replace the roof, we integrate easily and neatly the energy-efficient roof as part of your existing roof. You get a sleek and smooth transition between the traditional roof and energy efficient roof.
Financial freedom
With a solar energy system from SolTech you get your own energy source and thus reducing your need to buy energy for heating. Since the system has a very low operating cost, the energy price is determined by the cost of capital. When the system is paid in full, the energy is free. This way you will not have to worry about rising energy prices and expensive electricity bills. The SolTech System has a lifespan of more than 40 years.
One solution, three systems
Since 2011 the SolTech systems available in three versions, all with same award winning concept;
SolTech Alpha, the air borne thermal system
SolTech Sigma, the fluid borne thermal system
SolTech Power, the electricity generating system.
Both these systems have the same aesthetic design and superior service life but are adapted for different applications and buildings. SolTech Alpha is better suited for air-based heating systems, low temperature systems, like ventilation systems or heated foundations. SolTech Σigma is more suited for conventional water born heating systems and hot water production.
The SolTech Power system is developed to generate electricity by use of solar PV cells. The SolTech Power can easily be installed in parallell with the Sigma or Alfa systems.
