Solar energy potential in Barcelona

As we well know, the same amount of photovoltaic energy is not produced in the north of Europe as in the south of the continent, and Barcelona is a privileged city thanks to the number of hours of sunshine (almost 2,500; 2,453) and the high solar irradiation of the province of approximately 2,000 kWh/m2 (1,978.74 kWh/m2). This results in high photovoltaic energy production in homes and businesses, and therefore their solar energy potential.

As we can see in the graph, if we consider an average system of 3.4 kWp of installed power and a loss of 14%, the annual photovoltaic production is 5,319.47 kWh. The months with the highest production are May, June, July and August with 525, 528, 545 and 520 kWh, respectively. These high figures are important if we compare them with a city where the penetration of solar energy is much higher than that of Barcelona -such as Berlin- whose production capacity is barely 3,227 kWh. 😲 Surprising, right?

In Barcelona, 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 the electricity prices of 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, in the variable part of electricity consumption.

Inclination and orientation of solar panels in Barcelona

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 perfect inclination in Barcelona to achieve maximum performance of the solar panels should be about 30º to 40º -37º specifically- and the orientation towards the south.Solar panels facing south in Barcelona 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 at home or business in the morning, or more in the afternoon, increasing the home's own electricity consumption.
