Our 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
