Solar energy potential in Bilbao

Euskadi has around 1,900 hours of sunshine per year. Although it may seem like a low figure for what Spain is, we can safely compare this potential of Bilbao (1,694 hours of sunshine in Vizcaya) in Basque Country with that of some northern European cities where solar energy is normal, such as Berlin and Amsterdam. The latter have 1,728 and 1,662 hours of sunshine per year, respectively, therefore the photovoltaic capacity that the Bilbao has is usable, since the solar energy potential is similar to those of these main European capitals! 💪☀️

To calculate the photovoltaic production in Bilbao, let us take as an example a solar installation with 4.8 kWp of installed power, where the system will have an optimal inclination of 34º to the south, and the result will give us an annual production of photovoltaic energy of 5,498.11 kWh, with a loss of 14% of the system. The months of greatest production are June, July and August.

According to the Red Eléctrica de España (REE), Spanish households - and therefore in Bilbao - consume an average of 9 kWh per day and approximately 270 kWh per month, which represents about 3,240 kWh/year.

Grid electricity prices in 2021-2022 have averaged around €0.225/kWh (€225/MWh). A home without a photovoltaic energy system on the roof that consumes 270 kWh per month, would pay around €60 on average per month in the variable part of the electricity bill referring to consumption.

Inclinación y orientación en Bilbao

In Spain, the ideal average inclination of solar panels varies between 20° and 40°, and it is a concept that is closely linked to the latitude of the country. The closer it is to the Ecuador line, the angle of inclination of the panels will be less, since the sun's rays will hit perpendicularly. The inclination of most of the houses in Spain is between 20° and 35°.

Solar panels for self-consumption facing south in Bilbao with an optimal inclination of between 34° will produce the most electricity.

In Euskadi four climatic zones can be distinguished: the Atlantic slope to the north, a sub-Atlantic climate zone, a sub-Mediterranean climate zone, and the south where it transitions to a continental-type climate with dry and hot summers. In Bilbao (Vizcaya) the proximity to the Cantabrian Sea means that its climate is temperate oceanic, with rain throughout the year.

Get the most out of your solar panel installation in Bilbao

In Bilbao there are local aids such as the IBI discount (Real Estate Tax) and the ICIO discount (Tax on Construction, Installations and Works), in addition to aid and subsidies from European funds for solar self-consumption (NextGeneration EU).

In addition, let us take into account its temperate climate and its mild temperatures, together with the amount of solar energy that a square meter of surface receives in Bilbao, or Peak Solar Hour (HSP) peak is 3.86 kWh/m2. All these factors are beneficial to have an interesting photovoltaic production.

Frequently asked questions about photovoltaic installation in Bilbao

What is the price of a solar panel installation in Bilbao?

The price of a photovoltaic installation in Bilbao -and in any case- depends on the type of installation, size of the system and its components. 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 €6,000 and €8,000 for 15 panels.

What is the profitability of a photovoltaic installation in Bilbao? Are solar panels worth it?

From 4 to 6 years it is the approximate amortization of the investment, assuming that the bonuses have been counted in the first case, and without any kind of subsidies in the second. This is an average since each municipality of this Community has its specific bonuses and aid.

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