SolTech Sigma – Solar Energy made Beautiful
The new way for an efficient, clever and aesthetic solar energy solution
SolTech Sigma is designed to fit commercial, public, and private homes.
The SolTech Sigma proprietary developed absorbers specially adapted for the standards for roofing with tiles.
Combined with our award-winning design and concept solution, we can now offer a solar power solution that is as efficient as elegant and crystal clear.
A common house roof is subjected to about five times more energy each year, from the sun, than the house’s total energy consumption. SolTech allows You to use this energy while saving money. With SolTech Sigma you get both a beautiful ceiling and energy to your house.
Simple and ingenious
SolTech Sigma is based on several years of research at KTH in Stockholm that SolTech Energy has continuously developed. The principle is as simple as ingenious. Instead of traditional roof tiles of concrete or clay we utilize out own glass roof tiles. Beneath the glass tiles solar panels are installed that absorb of the incoming solar energy.
The energy captured is integrated with the building’s existing heating system, usually through a storage tank.
In the glass roof tiles installed our specially designed absorbers through which fluid is circulated. The absorbers are placed on an insulating layer to prevents losses. Covering the absorbers is a transparent layer of high quality polycarbonate to create the double layer of air under the glass roof tiles for maximum efficiency.
The Flexible System
SolTech Sigma is developed for integration with most existing central heating systems. The most common integration method is to a water borne central heating system via a storage tank.
SolTech Sigma utilizes traditional methods in the applying the system onto a roof using traditional battens. between the battens, an insulation layer is placed to prevent energy losses. The special absorbers are placed onto the insulation. A transparent poly carbon layer covers the absorbers. Covering the entire surface are the SolTech glass roof tiles.
The absorbers are connected to the accumulation tank, normally via the solar coil,
providing energy to the buildings total energy needs.
The fluid is circulated through the absorbers in a bespoke pattern for each installation to optimize efficiency and function. SolTech Energy will design this pattern based on the installations specific application and needs.
Dual function
With the SolTech System you get more than just a solar energy system, you get the premier integrated solar solution and a roof cladding with superior durability. The aesthetical properties of the SolTech Sigma are superior to any traditional solar collector system available in the market today.
