Bnei Ayish, Central District, Israel, located in the Northern Sub Tropics at coordinates 31.7886, 34.7636, offers generally favorable conditions for solar PV energy generation throughout the year, though with significant seasonal variations.

Seasonal Solar Production

Solar energy production at this location shows strong seasonal patterns. Summer is the peak production season, with panels generating approximately 8.33kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 7.28kWh/day. Production decreases considerably in autumn to 5.16kWh/day, while winter sees the lowest output at just 3.61kWh/day per kilowatt installed.

This seasonal variation means that a solar installation in Bnei Ayish will produce more than twice as much electricity in summer compared to winter months. The substantial spring production also makes this an extended period of good solar generation.

Optimal Panel Installation

For fixed panel installations at this location, the ideal angle to maximize year-round solar production is 27 degrees tilted toward the South. This specific angle optimizes the annual energy harvest by balancing seasonal sun positions throughout the year.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Bnei Ayish. Dust accumulation is a significant concern in this region, as Israel experiences dust storms particularly in spring and autumn. These dust deposits can reduce panel efficiency by 10-30% if not addressed.

High summer temperatures in this subtropical location can also decrease solar panel efficiency, as most panels lose efficiency when operating above 25°C. Additionally, the region occasionally experiences haze conditions that can diminish solar irradiance.

Preventative Measures

To maximize solar production despite these challenges, several preventative measures can be implemented:

• Regular cleaning schedule (at least quarterly) to remove dust accumulation, potentially more frequent during dust storm seasons
• Installation of panels with sufficient spacing for airflow to reduce temperature-related efficiency losses
• Selection of solar panels with lower temperature coefficients that perform better in hot conditions
• Use of anti-soiling coatings on panels to minimize dust adhesion
• Implementation of automated cleaning systems for larger installations

With these measures in place, a solar PV system in Bnei Ayish can effectively capitalize on the location's generally favorable solar conditions, especially during the highly productive summer and spring seasons.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 27° South in Bnei Ayish, Israel

To maximize your solar PV system's energy output in Bnei Ayish, Israel (Lat/Long 31.7886, 34.7636) throughout the year, you should tilt your panels at an angle of 27° 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 Bnei Ayish, 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 Bnei Ayish, Israel. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° 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	36° South in Autumn	46° South in Winter	24° 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 Bnei Ayish, 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 Bnei Ayish, 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 Bnei Ayish, Israel

The landscape surrounding Bnei Ayish, Israel is characterized by gently rolling hills and plains typical of the Shephelah region, which forms a transitional zone between Israel's coastal plain and the Judean Hills to the east. Situated approximately 31.7 kilometers southeast of Tel Aviv, Bnei Ayish rests at an elevation of about 80-100 meters above sea level.

Regional Topography

The immediate vicinity of Bnei Ayish features predominantly flat to moderately undulating terrain. To the west, the landscape gradually descends toward the Mediterranean coastal plain, with relatively unobstructed horizons and minimal shadowing effects from natural features. Moving eastward, the terrain becomes progressively more hilly as it transitions toward the Judean foothills. The soil composition in this region is primarily a mix of loess, alluvial deposits, and light to medium clay soils. Vegetation is sparse in many areas, consisting mainly of drought-resistant Mediterranean scrub and agricultural plots where irrigation is available.

Suitability for Solar PV Development

For large-scale solar photovoltaic installations, the western and southwestern areas surrounding Bnei Ayish present the most favorable conditions. These locations offer several advantageous characteristics: The relatively flat terrain minimizes the need for extensive grading and earthwork during construction, reducing development costs and environmental impact. The gentle slopes that do exist predominantly face south and southwest, providing optimal orientation for solar collection in the Northern Hemisphere. Areas to the immediate west of Bnei Ayish, extending toward Gedera and Ashdod, represent particularly promising locations. These lands combine favorable topography with proximity to existing electrical infrastructure and transportation networks, facilitating grid connection and maintenance access. By contrast, areas to the northeast become less suitable as the terrain rises toward the Judean Hills. These locations present more significant grading challenges and potential shadowing issues from the increasingly varied topography. The limited vegetation and relatively low agricultural value of certain parcels in the western sectors further enhance their suitability for solar development, potentially minimizing land-use conflicts. However, careful assessment would be necessary to avoid disruption to any ecologically sensitive areas or high-value agricultural land. The region's climate characteristics complement its topographical advantages, with clear atmospheric conditions throughout much of the year and minimal cloud cover during peak solar radiation periods.
