An outstanding innovation of the SMARTii team is SolEnEye, which is a concentrated solar power plant (CHP), which able to produce 1,5 kW electric & 2 kW thermal power, with 70% ,efficiency.

The SolEnEye can provide up to total energy independence for small business and individuals who are afraid of malfunctions, disruptions in the system, or want to do something about climate change.

SolEnEye was inspired by the fact that nowadays photovoltaic solar panels still have really high prices and they need multiple supporting systems. We wanted to develop a cheaper, easy-to-install asset which provides electricity. The SolEnEye not just fulfills these criteria but also can cater the house with hot water.

Brief description of the functioning of SolEnEye

The main function is that we are concentrating solar energy with a special 2.5m wide Fresnel-lens which heats up the evaporator of an ORC generator to T= 1’000°C which we produce electricity with.

At the condenser, we are extracting heat with a water cooling system which provides warm water for use.

As the figures show below the sphere has two main features. It is fixed to a pedestal but it can follow the movement of the sun throughout the day, to reach higher efficiency than the competitors. The other unique function is the cover which opens and closes automatically to protect the lens and the inner parts.
