Solarus

The technology and product development within Solarus has focused on the simple objective of making solar energy a major source of global energy supply. The constant innovation on product and production method, led by our technical team, allowed our panels to achieve high competitiveness and quality.

Solarus’ technical team pioneered MaReCo technology (also known as Maximum Reflection Concentrator) nearly fifteen years ago in a joint research and development project by accomplished Swedish research institutions and companies including Uppsala and Lund Universities, Vattenfall and the Swedish Energy Agency. The inventor and the CTO of Solarus, Stefan Larsson and his engineering team is one of the most experienced engineering teams when it comes to solar applications. They use a combination of the old knowledge regarding concentrating solar collectors that has been around for more than twenty years and the latest cutting edge technologies such as carbon fiber and silicon ribbon manufacturing.

Solarus has also solved a problem that many of our competitors face, namely that when sunlight heats up the solar cells to high temperaturesthe electricity becomes unstable. In our systems, there are features built into the design that helps to keep the solar cell at temperature levels where they function optimally.

The Reflector

Reflector used by Solarus is one of the pioneers among the maximum concentrating reflector and solar concentrating technology. Despite of its low weight and low material content, the Solarus collector is able to concentrate sunlight 3.5 times and follow the movement of the sun throughout the year without the need for a heliostat structure.

The reflector shape is designed to follow the sun’s movement throughout the day in such a way that all the light hits the heat absorbing tube (absorber). Therefore, the solar collectors can deliver high temperature of hot water even during cold winter days. The reduced heat loss is due to the fact that the absorber is smaller than other collectors and it is heated over a short period of time. The reflector has a unique seasonal adjusting feature such that it actually gives the highest efficiency when the sun is low in the sky. This in turn means that the solar panels can provide high output when the demand for heat is high over a year.

In addition, our reflector has almost consistent energy output efficiency across a wide range of temperatures, which together with its high scalability make it suitable for many different applications such as hot water heating, district heating, solar cooling as well as water sanitation and desalination.
