Resumen
- Rooftop Solar Photovoltaic systems may be crucial in the current energy scenario generating electricity on-site where buildings which are used for other purposes and have unused rooftop or other areas, such as, among other things, manufacturing processes, parking lots and residential building because these unused areas may be used to install Photovoltaic system. Moreover, the sizing of this type of systems is easily adjustable due to its modularity and its cost competitiveness when comparing other kinds of power generation sources. Currently, in Spain the potential to cover the electricity demand through Rooftop Solar Photovoltaic system may be between 20 and 30%. The industrial sector, which has a great unused rooftop and consume large amounts of energy, may play a major role in the energy transition. Electrical parameters of four Rooftop Solar Photovoltaic systems installed in Industrial Cooling and refrigeration industries have been monitored for one year in order to provide the input parameters to estimate the indices. The array power rating varies from 52.8 to 400 kW. Load matching metrics based on on-site measurements have been presented using recording intervals of 5 min. High self-consumption indices are achieved, close to 100%, while the self-sufficiency indices vary between 3.75 and 17.66%. Moreover, the sunshine self-sufficiency index ranges between 6.63 and 30.94%.
