Batteries that last 10% longer and ensure uninterrupted connection of essential equipment in locations without access to the electricity grid.
It is the result of the thesis 'Energy management in photovoltaic isolated by control algorithms priority loads' read last Friday at the Polytechnic University of Cartagena (UPCT).
Investigating Juan Gabriel Faxas has succeeded in extending the useful 10% battery life, the weak point of the isolated photovoltaic systems.
"They last between two and four years and account for about 40% of the cost of installation," says doctoral student.
The extension achieved in the lifetime of the batteries of the assignment by algorithms priorities loads dependent photovoltaic system, which is achieved also securing energy supplies to essential equipment, "as the refrigerator of vaccines a rural clinic in developing countries, "exemplifies Faxas, at the expense of less important teams off.
"With this system the probability of loss is very low, to ensure that during daily cycling facilities are not the priority disconnect" says Antonio Urbina Yeregui, the thesis director and coordinator of the PhD Program in Renewable Energy and Energy Efficiency UPCT.
Data supporting the research come from monitoring the UPCT performed an experimental system alone PV system of 4.2 kilowatts of crystalline silicon with which the animal facility of the University of Murcia lights.
"The conclusions of the thesis are generalizable to any grid photovoltaic installation, regardless of weather conditions and irradiance, and for any load profile," explains Urbina.
The new doctor, Juan Gabriel Faxas, is 29 and is Dominican.
She lives in Cartagena since five years ago began the Master in Renewable Energy Polytechnic University where he has become captain of one of their racing teams, the UPCT Solar Team.
During his years of scientific training has received a grant from the Government of Dominican Republic, which "takes years investing in renewable energy and the incorporation of doctors to their universities," says Urbina.
"Juan Gabriel is now qualified to supervise doctoral theses and manage research projects," he observes.
