Solar Energy Potential in Tulkarm, Palestine

Tulkarm, Palestine, located in the Northern Sub Tropics, offers a promising location for solar energy generation. With its coordinates at 32.3107° N, 35.0217° E, this area receives substantial sunlight throughout the year, making it suitable for solar photovoltaic (PV) installations. The seasonal variation in solar energy production at this location is significant. Summer months yield the highest output, with an average of 8.60 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, producing 7.20 kWh/day/kW. Autumn sees a moderate decrease to 5.28 kWh/day/kW, while winter experiences the lowest output at 3.53 kWh/day/kW.

Optimal Solar Panel Installation

For fixed panel installations in Tulkarm, the ideal tilt angle to maximize year-round solar production is 27 degrees facing South. This angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.

Peak Production Periods

The most favorable times for solar energy generation in Tulkarm are during the summer and spring seasons. These periods offer longer daylight hours and more direct sunlight, resulting in higher energy output. However, it's important to note that even during the less productive autumn and winter months, the location still receives a reasonable amount of solar radiation for energy generation.

Environmental Considerations

While Tulkarm generally presents favorable conditions for solar energy production, there are a few environmental factors to consider: 1. Dust and sand: The region's climate can lead to dust accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance of the panels can mitigate this issue. 2. Temperature: High summer temperatures may slightly decrease panel efficiency. Choosing heat-resistant panels and ensuring proper ventilation during installation can help maintain optimal performance. 3. Occasional cloudy days: Although relatively infrequent, cloudy weather can temporarily reduce solar output. Implementing energy storage solutions, such as batteries, can help balance energy supply during these periods. By addressing these factors during the planning and installation phases, solar PV systems in Tulkarm can achieve high levels of energy production throughout the year, making it an ideal location for solar energy investments.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 13 locations across Palestine. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 27° South in Tulkarm, Palestine

To maximize your solar PV system's energy output in Tulkarm, Palestine (Lat/Long 32.3107, 35.0217) 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 Tulkarm, Palestine

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 Tulkarm, Palestine. 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 Tulkarm, Palestine

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 Tulkarm, Palestine.

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 Tulkarm, Palestine

The topography around Tulkarm, Palestine, is characterized by a diverse landscape that transitions from coastal plains to rolling hills. Tulkarm itself is situated in the western part of the West Bank, near the border with Israel. The area is part of the larger Samarian Hills region, which forms the northern extension of the central Palestinian highlands. To the west of Tulkarm, the terrain gradually slopes down towards the Mediterranean coastal plain. This area is relatively flat and low-lying, with elevations typically below 100 meters above sea level. As one moves eastward from Tulkarm, the landscape becomes more varied and hilly. The terrain begins to rise, forming a series of gentle hills and valleys that are typical of the Samarian region. The hills around Tulkarm are generally not very steep or rugged, with most slopes being gentle to moderate. These hills are often terraced and have been used for agriculture for centuries, particularly for olive groves and other Mediterranean crops. The elevation in the immediate vicinity of Tulkarm ranges from about 50 to 150 meters above sea level, gradually increasing as one moves further east into the West Bank.

Areas Suitable for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have ample sunlight exposure, relatively flat or gently sloping terrain, and minimal shading from surrounding hills or vegetation. The coastal plain to the west of Tulkarm presents promising opportunities for solar PV development. This area benefits from its flat topography, which makes construction and maintenance of solar arrays easier and more cost-effective. The open nature of the terrain also ensures minimal shading throughout the day, maximizing solar energy capture. Some of the more gently sloping hillsides to the east and southeast of Tulkarm could also be suitable for solar PV installations. These areas often receive excellent sun exposure, particularly on south-facing slopes. However, care would need to be taken to avoid steep or unstable terrain, and to minimize the impact on existing agricultural activities. It's worth noting that while the hilly areas might offer good solar potential, they may present more challenges in terms of construction and grid connection compared to the flatter coastal regions. Additionally, any large-scale solar development would need to carefully consider land use issues, environmental impacts, and local community needs in this densely populated and agriculturally important region.
