Our Project

SOLARAYS PROJECT

The most economic way for mankind to face climate change is to find some renewable technologies with enough competitive advantage.

 

Solar energy is the most promising way to achieve this goal. The efficiency of the facilities and the cost of generating energy are the key factors for the massive implementation of renewables energies.

 

The most efficient solar technology —in terms of electricity generation— is the photovoltaic concentration (CPV). In addition, around 50% of all the energy consumed in the world is used for the heating supply covering also this need.

 

Electric installation is becoming the best option while expecting to be the big change in the energy sector in the coming decades.

Advantages of our Solar Energy System

Quick and easy installation on any roof or surface

Generation of stable energy during the day, allowing much more self-supply percentage and less batteries

Low weight

High energy density

Low visual impact

Supply of electric and thermal energy in only one module

Lower cost of energy generation
