Jatt, Haifa, Israel, located in the Northern Sub Tropics at coordinates 32.3911, 35.0418, offers a relatively good location for solar PV energy generation throughout the year, though with notable seasonal variations.

Seasonal Solar Production

Solar energy production in Jatt follows a predictable seasonal pattern. Summer months are exceptionally productive, generating 8.63kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 7.19kWh/day. Production decreases significantly in autumn to 5.23kWh/day, while winter shows the lowest output at just 3.46kWh/day per kW installed.

This means a typical 5kW residential system could produce around 43kWh on an average summer day but only about 17kWh during winter days. The significant difference between summer and winter production (about 60% less in winter) indicates that seasonal planning for energy needs would be beneficial for residents.

Optimal Panel Installation

For fixed solar panel installations in Jatt, Haifa, the ideal tilt angle to maximize year-round energy production is 27 degrees facing South. This angle has been calculated to optimize annual solar harvest based on the location's specific latitude and seasonal solar patterns.

Environmental and Weather Considerations

Several environmental factors in this region could impact solar production:

• Dust and sand: The Middle Eastern location means dust accumulation on panels can be significant, potentially reducing efficiency by 10-30% if not addressed.
• Seasonal temperature extremes: High summer temperatures can reduce panel efficiency, as most solar panels lose efficiency above 25°C (77°F).
• Occasional haze and air pollution: Being relatively close to industrial areas and urban centers can lead to atmospheric conditions that diffuse sunlight.

Preventative Measures

To maximize solar production in Jatt, Haifa, several preventative measures are recommended:

• Regular cleaning schedule: Implementing a bi-weekly or monthly cleaning routine, especially during dry seasons, to remove dust buildup.
• Temperature management: Installing panels with a few inches of clearance from the roof to allow airflow and reduce operating temperatures.
• Quality inverters: Using inverters designed to perform well in high-temperature environments.
• Seasonal angle adjustments: For those willing to adjust panels seasonally, steeper angles in winter (around 40-45 degrees) and flatter angles in summer (around 15-20 degrees) can increase seasonal production.

With proper installation and maintenance, Jatt's location can provide substantial solar energy, particularly from March through October when production levels remain consistently high.

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

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

Seasonal solar PV output for Latitude: 32.3911, Longitude: 35.0418 (Jatt, 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 27° South in Jatt, Israel

To maximize your solar PV system's energy output in Jatt, Israel (Lat/Long 32.3911, 35.0418) 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 Jatt, 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 Jatt, 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	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 Jatt, 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 Jatt, 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 Jatt, Israel

The topography around Jatt, Israel presents a diverse landscape situated within the northern region of Israel. Located at coordinates 32.3911° N, 35.0418° E, Jatt sits in an area characterized by rolling hills and valleys typical of the western slopes of Samaria. The settlement itself is positioned at a moderate elevation of approximately 150-200 meters above sea level, offering views of the surrounding terrain. The immediate vicinity of Jatt features gently undulating hills that gradually rise toward the east into more pronounced elevations of the Samarian highlands. To the west, the landscape transitions toward the coastal plain, with a more gradual descent in elevation. This transitional zone between highlands and coastal areas creates a varied topographical profile with numerous small valleys and ridgelines.

Surrounding Terrain Features

The terrain around Jatt includes several wadis (seasonal stream beds) that have carved shallow valleys through the landscape over time. These natural drainage channels typically run from east to west, following the general slope of the land toward the Mediterranean Sea. The soil composition consists primarily of terra rossa, a reddish clay-like soil common in Mediterranean regions, overlying limestone bedrock. Vegetation in the area follows typical Mediterranean patterns, with natural growth consisting of drought-resistant shrubs and scattered trees where human activity hasn't altered the landscape. Agricultural development has modified portions of the surrounding area, with olive groves and other cultivated lands occupying the gentler slopes and valley bottoms.

Potential Areas for Solar PV Development

For large-scale solar photovoltaic installations, the most suitable areas near Jatt would be found on the gently sloping hillsides and plateaus to the southwest and southeast of the settlement. These areas offer several advantageous characteristics for solar development: The southwestern slopes provide optimal sun exposure throughout the day due to their orientation. These areas typically receive minimal shadowing effects from surrounding terrain features, maximizing potential solar gain. The moderate gradient of these slopes allows for efficient arrangement of solar panels while minimizing the earthwork required for installation. Additionally, several relatively flat plateau areas within 5-10 kilometers of Jatt present opportunities for solar development. These locations combine good solar exposure with easier construction conditions. The southeastern region, where some of the terrain flattens before rising into higher elevations, offers particularly promising sites for larger installations. Areas to avoid would include the steeper eastern slopes where installation would be challenging and expensive, as well as the deeper wadi channels where flash flooding during rainy seasons could pose risks to infrastructure. The northwest direction, which faces toward more populated coastal areas, may present more land-use conflicts and higher land values that could make large-scale solar development less economically viable. Land that has been previously disturbed by human activity, such as abandoned agricultural plots or former industrial sites near the smaller communities surrounding Jatt, might offer opportunities for solar development with minimal additional environmental impact. These areas often already have some access infrastructure in place, which can reduce development costs. The moderate elevation of the region also helps avoid some of the extreme temperature conditions that can reduce solar panel efficiency, while still maintaining excellent solar radiation exposure characteristic of this Mediterranean climate zone.
