Are photovoltaic systems economically profitable in Spain?

Average annual soiling losses in photovoltaic panels have been modelled for Spain. The economic profitability of photovoltaic systems has been obtained for Spain. A CO 2 saving map is presented considering the installation of PV systems. GIS applied to PV generation estimation determined PV amortization maps in Spain.

How is Spain adapting to new solar regulations?

Spain's solar energy sector is adapting to new regulations designed to streamline project development and boost solar power adoption. A revised policy has replaced the former Feed-in-Tariff (FiT) scheme in Spain, creating a transition period for solar producers.

What is the economic profitability of PV plants in Spain?

Thanks to the QGIS software and the equations presented in the Materials and Methods section, both maps have been developed, presenting first the raster that corresponds to the economic profitability of the PV plants in Spain, shown in Fig. 13. As seen, the economic profitability range for a 261.879 MWp PV plant is between 404 and 1058 M€.

What is the Ibi deduction for photovoltaic panels?

Grants: the IBI deduction for the installation of photovoltaic panels is 50% for 3 years (depending on the regulation of each province). Subsidies: grants of 25%, 35% or 45% can be extended to a further 20% in the case of battery storage installation (under special conditions).

How much CO2 can a dimensioned photovoltaic plant save?

As a complement, the savings in terms of tonnes of CO 2 that would result from the construction of a dimensioned photovoltaic plant have been studied, arriving at a total annual saving figure of 3000M metric tonnes of CO 2. 1. Introduction
