随着许多国家实现平价上网，光伏自用引起了人们的极大兴趣。目前，受新规影响，西班牙正在开发大量新项目。根据对大学建筑内自耗式光伏电站一整年运行监测的经验，对此类建筑进行了法规、能源和经济分析。它是通过模拟建筑物的行为来进行的，其安装在西班牙法规允许的光伏发电范围内。分析表明，新的《自我消费皇家法令》与新的建筑规范之间具有良好的契合性。经济分析证明，当光伏发电与消费相匹配时，新的简化补偿方法可为建筑物的这种用途提供最佳的经济回报。投资回收期为8-9年，平准化度电成本（LCOE）纳入联营市场电价范围。这些结果显示了此类建筑光伏自耗的盈利能力。
As grid parity is reached in many countries, photovoltaic self-consumption is raising great interest. Currently, there is a big number of new projects being developed in Spain thanks to the new regulation. From the experience of the monitoring of one full year of operation of a self-consumption PV plant in a university building, a regulatory, energy, and economic analysis is made for this type of building. It has been carried out by simulating the behavior of the building with installations within the range of PV powers allowed in the Spanish regulation. The analysis shows the good fitting between the new Royal Decree of Self-Consumption and the new Building Code. The economic analysis proves that the new simplified compensation method gives the best economic return for this use of the buildings when the PV production is matched with the consumption. The time of return of investment is between 8 and 9 years, and the levelized cost of electricity (LCOE) is into the range of the pool market price of electricity. These results show the profitability of PV self-consumption for this type of building.
