Photovoltaic self-consumption for the Asociación El Despertar

The Asociación El Despertar provides assistance and care for children and young people with cerebral palsy, from infancy to adulthood. Cerebral palsy is characterized by alterations affecting posture and movement, often associated with other disorders involving language, hearing, and vision, and/or psychomotor impairment and epilepsy.

El Despertar consists of a school, a day center and a residential home, which cover all the needs of its users, as well as a large multidisciplinary team made up of educators, nurses, physiotherapists, and speech therapists, among others.

A photovoltaic system is planned to cover the consumption of the main building and the residential building.

Main building: The purpose of this photovoltaic system is to have a proportion of 67% of self-consumption of the photovoltaic production, out of the 55,000 kWh generated annually.

Residential building: This photovoltaic array is intended to achieve 65% of self-consumption of the power generated by the photovoltaic system, thanks to which 40,000 kWh per year will be generated.

For the system installed in the main building (which has estimated energy consumption of 138,500 kWh per year), the proposal consists of an output of 43 kWp, supported by two 20 kWn inverters. This output is optimized through the use of 545 Wp photovoltaic modules, due to the limited space on the roof, thereby maximizing the installed capacity.

For the system installed in the residential building (which has estimated energy consumption of 85,500 kWh per year), the proposal consists of an output of 27.5 kWp, with a 25 kWn inverter. The capacity of the photovoltaic array is maximized through the proposed 545 Wp photovoltaic modules, due to the constraints posed by the limited roof space.

In both cases, the proportion of self-consumption represents 30% of the annual energy requirements in each of the buildings. It is an ideal situation for relocating load consumption within the hours of solar production, with the consequent increase in the degree of solar self-sufficiency (equivalent fraction of solar coverage in relation to consumption/production), which can amount to almost 50% of the annual energy requirements, taking advantage of the surpluses generated (of around 31,000 kWh per year).

The two facilities will generate enough electricity to avoid the emission into the atmosphere of 56,812 kg of CO2 per year.
