As Solar Photovoltaics in buildings reaches maturity, grid integration and economic yield are topics of greater interest. Some strategies like demand shift management or storing electricity in batteries are proposed to reach a higher share of PV into the distribution grid. The price reduction of solar PV has driven a change in support policies from the feed-in tariff to net metering and, nowadays, to net billing schemes. With an increase in PV installations, aesthetical aspects are more valued, and coplanar placement of modules is preferred. By analyzing the operation of two PV installations: one residential and another industrial, we will show that smart use of these non-optimal orientations for the yearly production can be more convenient. Through the economic evaluation of several PV orientations, it is found that the economic performance could minimize the energy loss from optimal. The analysis of different alternatives for each study case has allowed us to identify several benefits for these orientations.

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.
