Seasonal Solar Performance
Solar energy production in Murcia varies significantly across seasons. Summer stands out as the peak period, with an impressive 7.77 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-most productive season, generating 6.04 kWh/day/kW. Autumn sees a decrease in output to 4.39 kWh/day/kW, while winter experiences the lowest production at 3.08 kWh/day/kW.
The substantial difference between summer and winter output highlights the region's distinct seasonal patterns. However, even during the least productive winter months, Murcia still maintains a respectable level of solar energy generation, making year-round solar power viable.
Optimal Panel Installation
To maximize year-round solar energy production in Murcia, fixed solar panels should be tilted at a 33-degree angle facing south. This optimal angle ensures the best overall performance across all seasons, balancing the high summer sun with the lower winter sun position.
Environmental Considerations
While Murcia's climate is generally favorable for solar energy, there are a few environmental factors to consider:
- Dust and pollen: Murcia's semi-arid climate can lead to dust accumulation on solar panels, potentially reducing efficiency. Regular cleaning and maintenance can mitigate this issue.
- High temperatures: Summer heat in Murcia can slightly decrease panel efficiency. Choosing heat-resistant panels and ensuring proper ventilation during installation can help maintain optimal performance.
Despite these minor challenges, Murcia remains an excellent location for solar PV installations. With proper planning and maintenance, solar energy systems in this region can provide substantial and consistent power output throughout the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Murcia
Seasonal solar PV output for Latitude: 37.9921, Longitude: -1.1201 (Murcia, Spain), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 33° South in Murcia, Spain
To maximize your solar PV system's energy output in Murcia, Spain (Lat/Long 37.9921, -1.1201) throughout the year, you should tilt your panels at an angle of 33° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Murcia, Spain
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Murcia, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 22° South in Summer | 42° South in Autumn | 53° South in Winter | 30° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Murcia, Spain
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Murcia, Spain.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Murcia, Spain
The topography around Murcia, Spain is quite diverse and interesting. The city itself sits in a relatively flat area known as the Segura River valley. This valley is surrounded by several mountain ranges, creating a unique landscape that transitions from lowlands to highlands.
To the north and west of Murcia, you'll find the Cordillera Subbética, a system of rugged mountains with steep slopes and rocky outcrops. These mountains create a natural barrier and contribute to the region's semi-arid climate. To the south and southeast, the terrain becomes more gentle, gradually descending towards the Mediterranean coast.
The immediate area around Murcia is characterized by a mix of agricultural land and low hills. These hills become more pronounced as you move away from the city center, especially towards the north. The Segura River, which flows through Murcia, has shaped much of the local topography, creating fertile plains that have been used for agriculture for centuries.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would combine flat or gently sloping terrain, high levels of sun exposure, and minimal environmental or agricultural impact.
The areas to the south and southeast of Murcia are particularly promising for solar PV projects. These regions tend to have more open, flat spaces that receive abundant sunlight throughout the year. The Campo de Cartagena, a large plain extending from the southern edge of Murcia towards the coast, offers excellent conditions for solar farms.
Additionally, some of the less fertile or abandoned agricultural lands in the Segura River valley could be repurposed for solar energy production. These areas are relatively flat and already have some infrastructure in place, which could facilitate the development of solar installations.
It's worth noting that while the mountainous areas to the north and west receive plenty of sunlight, their rugged terrain makes them less suitable for large-scale solar projects. The costs and environmental impact of preparing such sites would likely outweigh the benefits.
In conclusion, the most promising areas for large-scale solar PV near Murcia would be the flatter, open spaces to the south and southeast, as well as suitable portions of the Segura River valley. These locations offer the right combination of topography, sun exposure, and accessibility to make them ideal candidates for solar energy development.

Are there incentives for businesses to install solar in Spain?
Yes, there are several incentives for businesses wanting to install solar energy in Spain. These include the following:
1. The Spanish government offers a feed-in tariff (FIT) for businesses that install solar energy systems. This FIT guarantees a fixed price per kWh of electricity generated by the system over a period of 20 years.
2. Businesses can also benefit from tax deductions and other financial incentives when installing solar energy systems in Spain.
3. Companies may be eligible for grants or subsidies from regional governments or local authorities to help cover the cost of installation and maintenance of their solar energy systems.
4. Businesses may also be able to take advantage of net metering, which allows them to sell excess electricity generated by their solar energy system back into the grid at market prices, thus reducing their overall electricity costs even further.
