Cádiz is an optimal area for the installation of this type of self-consumption systems. As we can see in the graph, if, for example, a peak power of 3.4 kWp is installed, with an angle of inclination of the plates of 33º and contemplating a system loss of 14%, the annual production of photovoltaic energy in Cádiz it would be 6,148.16 kWh. The months of greatest production are from May to August with 596.8; 596.15; 635.8 and 624.28 kWh, each of these four months, with an annual irradiation in the plane of 2,205.71 kWh/m2. Note that the result of the PV calculation is the monthly and annual average energy production of the PV system.

In Cádiz, the Red Eléctrica de España (REE) indicates that Spanish households consume an average of 9 kWh per day and approximately 270 kWh per month, which represents about 3,240 kWh/year. Likewise, that the prices of electricity from Cádiz in 2021-2022 have averaged around €0.225/kWh (€225/MWh), so that a household without a solar energy system that annually consumes from the network these 3,240 kWh would pay around €730 per year in the variable part of the electricity bill referring to consumption.

Inclination and orientation of solar panels in Cádiz

In Spain, the ideal average inclination of the panels varies between 20º and 40º since it is directly related to the latitude of the country. The closer a city is to the equator, the less the angle of inclination of the panels will be, since the sun's rays will strike perpendicularly.

Although the inclination of the photovoltaic installations in most homes in Spain is between 20º and 35º, the solar panels in Cádiz face south with an approximate inclination of 33º to achieve maximum performance.It should be noted that the south facing solar panels in Cádiz will produce the most energy, but if you want to place the modules facing east or west it is also worth it, especially if you need to cover electricity needs in the morning, or later in the afternoon, respectively, increasing the home's own electricity consumption.

In Cádiz you can obtain NextGen self-consumption subsidies or European funds for the residential sector and in more common installations with a peak power of less than 10kWp, the aid is €600 for each kWp of the installation and €490 per kWh in the battery storage. Although it is less common, in the case of installations greater than 10kWp, subsidies are between €450 and €300 per installed kWp.

These subsidies are managed by the Andalusian Energy Agency: You can obtain more information in the Official Bulletin of Junta de Andalucía. Grants are limited and are awarded on a first-come, first-served basis. The first batch allocated to these aids was sold out and there is already a waiting list for the new batch.

For this reason, the Ministry for the Ecological Transition and the Demographic Challenge (MITECO) extends in 2022 by 505 million euros the Program of incentives for self-consumption, energy storage and thermal installations with renewables in the autonomous communities that have already exhausted the funds of the Program that they originally received and among them is the Community of Andalucía, and therefore Cádiz.
