Daburiyya, Northern District, Israel, located in the Northern Sub Tropics at coordinates 32.689°N, 35.3779°E, offers reasonably good conditions for solar photovoltaic energy generation throughout the year, though with significant seasonal variation.

Seasonal Solar Performance

The solar energy output at this location varies considerably across the seasons. Summer provides the highest production at 8.63 kWh per day per kW of installed solar capacity, making it the peak generation period. Spring follows as the second-best season with 7.19 kWh per day per kW, offering strong solar potential during the March-May period. Autumn production drops to 5.23 kWh per day per kW, representing moderate generation capabilities. Winter shows the lowest output at 3.47 kWh per day per kW, which is typical for locations in the Northern Sub Tropics due to shorter days and lower sun angles.

Optimal Panel Configuration

For maximum year-round solar production at Daburiyya, Northern District, solar panels should be installed at a fixed tilt angle of 28 degrees facing south. This angle has been calculated to optimize total annual energy output by accounting for the sun's varying position throughout the year and weighting for solar irradiance potential.

Local Environmental Factors

Several environmental and weather factors in this region can impact solar energy production:

• Desert dust and sand particles carried by regional winds can accumulate on solar panels, reducing their efficiency
• Occasional sandstorms, particularly during spring months, can significantly decrease solar output temporarily
• High summer temperatures can reduce panel efficiency, as photovoltaic cells perform less effectively in extreme heat
• Seasonal rainfall patterns may create periods of reduced solar irradiance during winter months

Preventative Measures

To maximize solar energy production despite these challenges, several installation strategies should be considered. Regular panel cleaning schedules are essential, with more frequent cleaning during dusty periods or after sandstorms. Installing panels with anti-soiling coatings can help reduce dust accumulation and make cleaning more effective. Proper ventilation around solar panels helps manage high summer temperatures, allowing air circulation to cool the panels and maintain better efficiency. Choosing panels with good temperature coefficients ensures better performance during hot weather. Installing monitoring systems allows for quick identification of reduced performance, enabling prompt maintenance when environmental factors impact output. Strategic positioning away from local dust sources and ensuring adequate spacing between panel rows can also help minimize environmental impacts on solar generation.

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

Seasonal solar PV output for Latitude: 32.689, Longitude: 35.3779 (Daburiyya, Israel), 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 28° South in Daburiyya, Israel

To maximize your solar PV system's energy output in Daburiyya, Israel (Lat/Long 32.689, 35.3779) throughout the year, you should tilt your panels at an angle of 28° 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 Daburiyya, Israel

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 Daburiyya, Israel. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° South in Summer	37° South in Autumn	47° South in Winter	25° 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 Daburiyya, Israel

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 Daburiyya, Israel.

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 Daburiyya, Israel

Topographical Features Around Daburiyya

Daburiyya sits in the Lower Galilee region of northern Israel, positioned at the base of Mount Tabor, one of the most recognizable landmarks in the area. The village is located approximately 318 meters above sea level on relatively gentle slopes that extend from the prominent mountain. Mount Tabor itself rises dramatically to 588 meters, creating a distinctive dome-shaped peak that dominates the local landscape.

The surrounding terrain is characterized by rolling hills and valleys typical of the Galilee region. To the north and east, the land gradually rises toward higher elevations, while to the south and west, the topography becomes more moderate with gentler gradients. The area features a mix of agricultural terraces, natural hillsides, and scattered woodland areas that have been shaped by centuries of human habitation and cultivation.

The Jezreel Valley lies to the southwest of Daburiyya, representing some of the flattest and most fertile land in the region. This broad valley floor contrasts sharply with the more undulating terrain immediately around the village. Small wadis and seasonal watercourses cut through the landscape, creating minor variations in elevation and drainage patterns throughout the area.

Optimal Locations for Large-Scale Solar Development

The most suitable areas for large-scale solar photovoltaic installations would be found on the gentler slopes and flatter areas southwest of Daburiyya, particularly those sections that transition toward the Jezreel Valley. These locations offer several advantages including reduced grading requirements, easier access for construction and maintenance equipment, and minimal shading from surrounding topographical features.

South-facing slopes with gradients of less than 15 degrees would be particularly well-suited for solar development, as they provide natural optimal positioning for solar panels while remaining economically viable for large-scale construction. Areas with consistent elevation and minimal variation would reduce infrastructure costs and improve overall system efficiency.

The flatter agricultural areas in the valley floors, while potentially competing with existing land uses, represent the most technically straightforward locations for solar installations. These areas typically have good road access, established electrical infrastructure connections, and minimal topographical challenges that could complicate construction or ongoing operations.

Conversely, the steeper slopes of Mount Tabor and the more rugged terrain to the north would be less suitable for large-scale solar development due to challenging access, increased construction complexity, and potential shading issues from the varied topography. The most practical solar development would likely focus on the transitional zones between the hillier areas around Daburiyya and the flatter valley regions to the southwest.
