To achieve the mandatory levels of EU-wide greenhouse gas emissions by 2050 will require switching to low-carbon energy sources as renewable sources, and LCpT fits totally in this commitment. Alternatives currently in the market rely on batteries to store energy, while our solution implies the use of an intelligent combination of batteries and supercapacitors for a better and more efficient energy storage utilization. Our solution will provide the energy storage needed to balance the power fluctuations produced by renewable energy sources bringing to the customers a complete solution to manage their production and be self-sufficient to satisfy their energy consumption, reducing significantly the bill up to 90% thanks to its 94% degree of autonomy, allowing a payback of 4 years for the final user. LCpT can be used in residential buildings and industrial complexes equipped with renewable energy sources, and it can be also used in antennas, electric cars, advertising panels and in the UPS field. In addition, the solar trailer could be addressed for special applications such as off-grid applications and civil operations in emergency camps where no electricity is available.
