Fotovoltaica | PV www.futurenergyweb.es 82 FuturEnergy | Septiembre/Octubre September/October 2020 estructura importada de Italia, el sistema Vela de Sun Ballast. Se trata de un sistema de hormigón apto para suelos planos que cumple la función tanto de estructura de soporte como de contrapeso del módulo fotovoltaico. Son muchos los proyectos desarrollados en el sector residencial, un buen ejemplo es un sistema 100% autónomo, sin conexión a red, instalado en la isla de Tenerife. La instalación de 12 kWp está equipada con módulos LONGi de 320 W, sistema Outback Power trifásico de 21 kW de potencia con tres inversores Radian de 7 kW, monitorización y sistemas de conexión Outback y baterías Rolls Battery de 2800 Ah/2 V, a 48 V, con un generador de apoyo de 20 kW. En el segmento de instalaciones de pequeña escala, la compañía ha realizado varias instalaciones en el sector residencial, que suman un total de 150 kW en los últimos tres meses. Estas instalaciones aportan eficiencia y kWh verdes a clientes particulares que apuestan por esta tecnología. Entre ellas están sistemas con módulos monocristalinos LONGi de 360W y paneles de 330W SunPower Black, que a parte de su gran eficiencia dan un toque personal de estilo. En estas instalaciones se han utilizado sistemas de inversores SolarEdge de 1,5-2.2-3 y 4 kW con optimizadores, que dan un plus más de calidad a las instalaciones. made of anodised aluminium from Extrugasa. Thanks to this installation, the cooperative has achieved a 34% saving in the cost of electricity. The facility generates an estimated 59,799 kWh per year. The total annual self-consumption at the cooperative amounts to 54,516 kWh, thereby achieving a self-sufficiency of 33.7%, with 93.2% of all the power generated being used for its own processes. During the first year the PV installation achieve a total saving of €5,664, which represents a 35.9% saving in the total cost of the power factor. As a result, this will avoid the emission of 26.9 t CO2 per year, which translates into a total saving of 671.7 tonnes of CO2 in 25 years. The estimated saving over 10 years is €65,500 and €211,700 in 25 years, with an estimated return of 15.4%, meaning that the installation will be amortised in 6 years. One of the references for the company in the tertiary sector is the facility installed at the Royal Yacht Club of Santa Cruz de la Palma: a 28.8 kWp system equipped with 360W monocrystalline modules from LONGi, 2 Fronius inverters and a concrete structure from Sun Ballast. Thanks to this system, the owners will save 25% on their electricity bill. A new structure imported from Italy has been used for this installation: the sailshaped ‘Vela’ system from Sun Ballast. This is a concrete system suitable for flat floors, which acts as both support structure and counterweight for the PV module. Many projects have been undertaken in the residential sector. One good example a 100% autonomous, off-grid system, installed on the island of Tenerife. The 12 kWp installation is equipped with 320Wmodules from LONGi; a 21 kW threephase Outback Power system with three 7 kW Radian inverters; Outback monitoring and connection systems; and batteries from Rolls Battery from 2800 ah/2 V to 48 V, with a 20 kW backup generator. In the small-scale segment, the company has executed several installations in the residential sector in the last three months, totalling 150 kW. Installations such as these offer private clients opting for this technology efficiency and green kWh. These include systems with 360Wmonocrystalline modules from LONGi and 330W panels from SunPower Black which, apart from their high level of efficiency, add a personal touch of style. SolarEdge inverter systems with optimisers have been used in these installations, with capacities of 1.5, 2.2, 3 and 4 kW that add an extra layer of quality to the installations.
