Nahalal, Northern District, Israel, situated in the Northern Sub-Tropics, offers a promising location for solar PV energy generation. This area experiences substantial seasonal variations in solar output, which significantly impacts the efficiency of photovoltaic systems throughout the year.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy production in Nahalal, Northern District, with an impressive daily output of 8.63 kWh per kW of installed solar capacity. Spring follows closely, generating 7.19 kWh/day. Autumn sees a moderate decrease to 5.23 kWh/day, while winter experiences the lowest output at 3.46 kWh/day.

These figures indicate that Nahalal is particularly well-suited for solar energy generation during the warmer months, from late spring through early autumn. However, the significant drop in winter output suggests that supplementary energy sources might be necessary during the colder months to maintain consistent power supply.

Optimal Panel Installation

For fixed panel installations in Nahalal, Northern District, the ideal tilt angle to maximize year-round solar production is 28 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Nahalal generally offers favorable conditions for solar energy production, there are a few environmental factors to consider:

• Dust and sand: The region's arid climate can lead to dust accumulation on solar panels, potentially reducing their efficiency.
• High temperatures: Extreme heat during summer months may slightly decrease panel efficiency.

To mitigate these issues, regular cleaning of the panels is recommended to remove dust buildup. Additionally, installing panels with a slight elevation to allow air circulation can help manage heat-related efficiency losses. Choosing high-quality, heat-resistant panels is also advisable for this climate.

Overall, Nahalal presents a highly suitable location for solar PV energy generation, particularly during the warmer months. With proper installation and maintenance, solar systems in this area can provide substantial renewable energy output throughout the year.

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 Nahalal

Seasonal solar PV output for Latitude: 32.693, Longitude: 35.2024 (Nahalal, 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 Nahalal, Israel

To maximize your solar PV system's energy output in Nahalal, Israel (Lat/Long 32.693, 35.2024) 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 Nahalal, 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 Nahalal, 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 Nahalal, 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 Nahalal, 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 Nahalal, Israel

The topography around Nahalal, Israel, located at latitude 32.693 and longitude 35.2024, is characterized by gently rolling hills and fertile valleys typical of the Lower Galilee region. This area is part of the Jezreel Valley, a large, flat plain surrounded by higher elevations. The landscape is a mix of agricultural fields, scattered woodlands, and small settlements. Nahalal itself sits on a low hill, with the terrain gradually sloping down towards the valley floor. To the north and east, the land rises more steeply towards the Nazareth mountains, while to the south and west, it opens up into the broader expanse of the Jezreel Valley. The elevation in this area ranges from about 50 to 200 meters above sea level, creating a varied but generally mild topographic profile.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, the Jezreel Valley offers promising potential. The relatively flat terrain of the valley floor provides ideal conditions for solar farms, as it minimizes the need for extensive land preparation and allows for efficient arrangement of solar panels. The areas to the south and southwest of Nahalal, where the Jezreel Valley widens, would be particularly well-suited for solar PV projects. These locations benefit from ample sunlight exposure throughout the year and have fewer obstructions that could cast shadows on the panels. Additionally, the presence of existing infrastructure and proximity to population centers in this region could facilitate the integration of solar-generated electricity into the power grid. It's worth noting that while the agricultural value of the Jezreel Valley might pose some challenges for large-scale solar development, there may be opportunities for dual-use projects that combine solar energy production with certain types of farming or grazing activities. This approach could help balance the region's agricultural heritage with the growing need for renewable energy sources. The hillsides surrounding the valley, while less ideal for expansive solar farms due to their slopes, could potentially accommodate smaller-scale solar installations. These areas might be suitable for distributed solar projects or community solar initiatives that could complement larger installations in the valley. Overall, the topography around Nahalal offers a mix of terrains, with the flat expanses of the Jezreel Valley presenting the most promising opportunities for large-scale solar PV development in the vicinity.
