Badajoz, Spain presents a moderately good location for year-round solar PV energy generation, though with significant seasonal variation typical of its Northern Temperate Zone position.

Seasonal Solar Performance

The solar energy output at this location shows strong seasonal patterns. Summer delivers the highest production at 8.33 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows as the second-best period with 6.35 kWh per day per kW, offering excellent energy production as daylight hours increase and weather conditions improve. Autumn sees a notable decline to 4.43 kWh per day per kW as the region transitions toward winter conditions. Winter presents the most challenging period for solar generation, dropping to just 2.68 kWh per day per kW of installed capacity - less than one-third of summer production levels.

Optimal Panel Configuration

For maximum year-round energy production at this Badajoz location, solar panels should be installed at a fixed tilt angle of 33 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and weighting for actual solar irradiance conditions.

Local Factors Affecting Solar Production

Several environmental and weather factors in the Badajoz region can impact solar panel performance and require consideration during installation. Dust and Agricultural Particles: Badajoz sits in an agricultural region of Extremadura, where farming activities and dry conditions can generate significant dust and pollen. These particles accumulate on solar panels, reducing their efficiency by blocking sunlight from reaching the photovoltaic cells. Extreme Summer Heat: While summer provides peak solar irradiance, the intense heat common in this part of Spain can actually reduce panel efficiency. Solar panels operate less efficiently as temperatures rise above their optimal operating range. Seasonal Weather Patterns: The region experiences Mediterranean continental climate characteristics, including potential for sudden weather changes and occasional severe storms that could affect panel positioning or cause debris accumulation.

Preventative Measures for Enhanced Performance

Several installation strategies can help maximize solar energy production despite these local challenges:

• Regular Cleaning Systems: Install automated cleaning systems or establish frequent manual cleaning schedules to remove dust, pollen, and agricultural debris that accumulate on panel surfaces
• Adequate Ventilation: Ensure proper spacing and mounting techniques that allow air circulation behind panels to reduce heat buildup and maintain optimal operating temperatures
• Robust Mounting Systems: Use high-quality, weather-resistant mounting hardware designed to withstand local wind conditions and potential storm impacts
• Strategic Panel Placement: Position panels to minimize shading from nearby agricultural structures or vegetation while maintaining the optimal 33-degree south-facing angle

Overall Assessment

Despite seasonal variations and local environmental factors, Badajoz offers reasonable conditions for solar PV installation. The strong summer and spring production periods help offset the lower winter output, while proper installation techniques and maintenance can effectively address the main local challenges of dust accumulation and heat management.

Solar output per kW of installed solar PV by season in Badajoz

Seasonal solar PV output for Latitude: 38.867, Longitude: -6.9662 (Badajoz, 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 Badajoz, Spain

To maximize your solar PV system's energy output in Badajoz, Spain (Lat/Long 38.867, -6.9662) 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 Badajoz, 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 Badajoz, 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
23° South in Summer	43° South in Autumn	54° South in Winter	31° 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 Badajoz, Spain

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Badajoz, Spain

Topographical Features of Badajoz

Badajoz sits in the southwestern region of Spain, positioned within the broad Guadiana River valley in the autonomous community of Extremadura. The city occupies a relatively flat position along the Portuguese border, with the terrain characterized by gentle undulations and modest elevation changes. The landscape around Badajoz forms part of the Iberian Peninsula's western plains, where the topography transitions from the higher elevations of central Spain down toward the Atlantic coastal regions. The Guadiana River flows through this area, creating a natural corridor that has shaped the local geography over millennia. The river valley provides fertile alluvial soils, but also creates a landscape of gentle slopes and terraced areas that extend outward from the main watercourse. To the north and south of the city, the terrain gradually rises into low hills and plateaus, though these elevations remain modest compared to Spain's mountainous regions. The surrounding countryside consists primarily of rolling plains interspersed with occasional low ridges and shallow valleys. These features create a mosaic of different micro-topographies, from flat agricultural fields to gently sloping pastureland. The area lacks significant mountainous barriers, allowing for relatively unobstructed views across the landscape and contributing to the region's characteristic open, expansive feel.

Optimal Areas for Large-Scale Solar Development

The topographical characteristics around Badajoz present several advantageous conditions for large-scale solar photovoltaic installations. The most suitable areas would be the extensive flat to gently sloping plains that extend both north and south of the city. These areas offer the dual benefits of minimal grading requirements and reduced installation costs, while providing ample space for expansive solar arrays. The elevated plateaus and low hills surrounding the Guadiana valley present particularly attractive opportunities for solar development. These slightly raised areas benefit from excellent exposure conditions while remaining accessible for construction and maintenance activities. The gentle slopes found on these elevated areas can actually enhance solar panel performance when properly oriented, as they provide natural tilting that can be optimized for solar collection. Areas to the east and southeast of Badajoz appear especially promising, where the landscape opens into broad, relatively flat expanses with minimal topographical obstacles. These zones combine favorable terrain conditions with sufficient distance from urban development, reducing potential land use conflicts. The low population density in these areas also means fewer concerns about visual impact or competing land uses. The terrain west toward the Portuguese border also offers suitable conditions, though developers would need to consider international boundary regulations. The landscape in this direction maintains the same gentle, rolling character that makes the region attractive for solar development, with extensive areas of low-productivity agricultural land that could potentially be converted to energy generation. Areas immediately adjacent to the Guadiana River and its tributaries would be less suitable due to flood risk considerations and the typically higher agricultural value of these fertile valley bottoms. Similarly, the few areas with steeper slopes or irregular terrain would present greater challenges for large-scale installations, though they might still be viable for smaller projects with appropriate engineering solutions.
