Analysis of the impact of the photovoltaic generation in a nearly Zero-Energy Building

Abstract

This report contains the analysis ofdifferent measures applied to a single-family house, in the region of Asturias, in order to be considered a nearly Zero-Energy Building.The situation and the climatic conditions are studied to see its impact on the architectural design of the house, the selection of specific isolation materials and the use of appropriate renewable energy systems. The renewable energy systems selected are a biomass heating system and a water/air heat pump.A photovoltaic system is designed,according to the energetic conditions of the house, to cover the electrical demand. The aim is to reduce the environmental impact and also the electrical bill. The installation designed consistsin a solar field made of 14 photovoltaic panels to generate the 100% of the electric demandof the house. It is a grid-connected and built-integrated system. No batteries will be used, and the energy not consumed is sent to the grid. The fact that no batteries are used and that the exceeding energy is sent to the electric company, contribute toeconomic viability of the system
