Efficient solar solutions
With more than 30 years of experience in the production of surface-refined aluminium and copper strips, we also specialise in the production of semi-finished products for environmentally friendly solar energy generation.
Thanks to our various vacuum coating systems (PVD) and a lacquer system specially developed for sol-gel methods, we produce selectively absorbent or highly reflective coating systems using the coil-to-coil process.
We offer selective absorption coating systems, which are used in various types of solar collectors. Our coating systems are continuously vapour coated and sputtered in an air-vacuum-air process using PVD methods, achieving absorption rates of 95% with a low emissivity of no more than 5%.
New — mirotherm® Control
mirotherm® Control is our new, selective absorption coating which integrates protection against overheating. It reduces the stagnation temperature of flat plate collectors by approximately 40°C. mirotherm® Control ensures maximum efficiency and operational reliability – even at high outside temperatures or low demand for hot water. The new coating achieves a solar absorption of 96% and an emissivity which is temperature dependent.
We offer reflective surfaces with a total solar reflection ranging from 85% to 90%. Thanks to a weather-resistant nano-composite layer, all MIRO-SUN® products are ideal for outdoor use in CPC (compound parabolic concentrator) mirrors, in vacuum tube collectors or parabolic trough concentrators (CSP = concentrated solar power). In addition, we provide a concentrating reflector material for photovoltaic applications (CPV = concentrated photovoltaics).
All of our solar products are currently sold, processed and installed by partner companies on five continents. We are the first company in the world to reach the milestone of more than 21 million square metres of absorber surface sold. What’s more, our worldwide sales network ensures targeted advice and on-site support.
