UPCT graduates carry out the first photovoltaic installation of community self-consumption in Cartagena (13/02/2020)

The plates installed by Crusol, a company created by engineers trained in the Polytechnic, will allow a saving of 63% in the electricity bill of a building in the city center

“Photovoltaic energy has arrived in Cartagena”, this is the resounding demand of engineers trained at UPCT Gonzalo Cruzado and Miguel Martínez, founders of Crusol company that today installed a photovoltaic power generation system on Reina Victoria Street to serve a community of neighbors, the first in the city that will benefit from the decree that since last year regulates and facilitates community electric self-consumption.

The 24-dwelling building will reduce the electricity bill by 63% and the carbon footprint by 49% by using solar panels to generate the electricity consumed by the elevator, hall lights and water pumps in the building , among other common electrical installations.

The community of neighbors has invested about 3,000 euros, which will pay off in just three years.

“The result of the installation in the common areas will demonstrate its profitability and will facilitate that the neighbors decide to extend it to cover also the electricity consumed in the houses,” explains Gonzalo Cruzado, remembering that it is enough that 33% of the owners bet on photovoltaics .

The average cost per house to join the self-consumption is about one thousand euros.

The young engineers presented the project at a meeting of residents of the building, anticipating the results of the long-term photovoltaic installation and calculating all possible invoices.

“We handle millions of data,” says Miguel Martínez.

Before a decree of self-consumption that has radically changed the rules of the game, the UPCT alumni highlight the main novelties: although photovoltaic panels are placed, the building is still connected to the electricity grid, so it does not need batteries, and the energy generated but not consumed in the property is poured and sold on the net.

"Promoting electric self-consumption, sustainability and energy efficiency in is a way to return to society the investment in our university education," says Cruzado, highlighting the technical preparation obtained at the Polytechnic of Cartagena.

“For the first time, it is more profitable to generate your own electricity than to buy it,” adds his partner, remembering that “the prices of the equipment have dropped a lot and you no longer have to invest in batteries, because the remaining electricity can be turned over to the grid "

Both advocate changing the paradigm of the energy system, so that “cities cease to be electric sinks and become power generators”.

Crusol, created just a few months ago, already has a portfolio of fifty clients and has carried out photovoltaic installations in individual homes before leading the first milestone of community self-consumption in Cartagena.

The company offers annual maintenance, as well as cleaning of the solar panels, guaranteeing a constant and correct operation.

Gonzalo Cruzado has a degree in Industrial Chemical Engineering from the UPCT, in which Miguel Martínez studied the degree in Industrial Technology Engineering and the Master's degree in Industrial Engineering.
