Solar energy potential in Castellón

Castellón is in an excellent situation in terms of solar energy due to the large amount of sun that the area receives (3,321 hours), which is greater than in other Autonomous Communities of Spain. The country has an average of 2,500 hours of sunshine per year, although this value is not reached in the northern areas and several southern regions can exceed 3,000 hours per year. The high solar irradiation of the area allows the photovoltaic production capacity in Castellón to be also high.

With an average photovoltaic installation of 3.4 kWp of installed power and an annual irradiation in Castellón punctually, on the plane of 1,963.7 kWh/m2, the annual production of photovoltaic energy is 5,210.44 kWh with an angle of inclination 36° of the photovoltaic equipment and assuming a system energy loss of 14%. The largest energy production is distributed by months from May to August.

The data shows that Castellón is an optimal area for the installation of this type of self-consumption equipment.

In Castellón, 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. In addition, the REE has also indicated that electricity prices from the grid in 2021-2022 have averaged around €0.225/kWh (€225/MWh), so that a household without a solar energy system that consumes monthly from the network these 270 kWh would pay around €60 per month on your bill, and around €730 for the 3,240 kWh per year in the variable part of electricity consumption.

Inclination and orientation of solar panels in Castellón

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. The orientation of the solar panels will affect the production of electricity in Castellón and their inclination should be 36º.

Get the most out of your solar panel installation in Castellón

In Castellón, a city of 172,589 inhabitants without counting its metropolitan area, a home with an average electricity bill of €70 per month would require the installation of approximately 10 solar panels. The high solar irradiation of the area contributes to a rapid return on investment. Additionally, the use of microinverters can help limit solar panel output loss caused by shading.

Frequently asked questions about photovoltaic installation in Castellón

How much does a solar panel installation cost in Castellón?

The price of a photovoltaic installation in Castellón, and as is generally the case anywhere, depends on the type of installation, the size of the system, its components, and the registration and legalization procedures. Considering all the necessary materials: panels, inverter, wiring and installation costs such as labor for a single-family home that requires 10 panels, the approximate price would be €5,500 and €7,000 for 15 panels.

Is a photovoltaic installation profitable in Castellón? Are solar panels worth it?

The recovery of the investment in Castellón if none of the bonuses (IBI and ICIO) are accessed, would be done in just over 6 years, but if the aid is available, the investment would be recovered in just over 4 years. And if, in addition to these bonuses, subsidies from European funds are obtained, this time is reduced by almost 3 years.

How much can be saved with an installation of solar panels?

With a photovoltaic installation in Castellón you can save approximately 60% and up to 70% on your electricity bill (in the variable part of it, referring to electricity consumption).

What procedures and/or permits are needed for photovoltaic installations in Castellón?

Although normally the installation companies in Castellón are in charge of managing all the procedures so that their clients do not have to worry about it, it should be noted that the Valencian Community offers simplification of the procedures. To start a photovoltaic installation, we could say that normally only a Responsible Declaration is needed, not a Building License. However, we must be vigilant since in practice there are still Town Halls that require said License.

Is there aid for the installation of solar panels in Castellón in 2023?

IBI discount: %, years, uses and limitations

What subsidies are there and how to apply for self-consumption aid in Castellón?

The NextGen subsidies or European funds from the EU, are aids that represent a great support since the amounts are €600 for each kWp of the installation and €490 per kWh in the storage battery, in the case of installations less than 10kWp . In the case of installations larger than 10kWp, the aid varies between €450 and €300 per kWp installed. These grants are limited and are awarded in order of presentation. They are managed by the Valencian Institute of Business Competitiveness (IVACE) and the processing is done through the General Directorate of Ecological Transition of the Generalitat Valenciana at the Electronic Headquarters of the Generalitat Valenciana, through the corresponding link:https://www.gva.es/es/inicio/procedimientos?id_proc=21988. Both the application and the technical report will be submitted to the Telematic Registry of the Generalitat.

The deadline for submitting applications is from November 2, 2021 until the allocated budget or budget reallocation is exhausted, and always until December 31, 2023 at the latest. 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 Valencian Community.
