Solar PV Analysis of Jounieh, Lebanon
The location at Jounieh, Lebanon is generally good for generating solar power. This is because it's in the Northern Sub Tropics where there is plenty of sunlight all year round. The amount of energy you can generate depends on the season. In summer, you can expect to generate about 8.62 kilowatt-hours per day for each kilowatt of solar panels you have installed. In autumn, this drops to about 5.23 kilowatt-hours per day, and in winter it's even lower at around 3.31 kilowatt-hours per day due to shorter daylight hours and less intense sunlight. However, things improve in spring when you can expect to generate around 7 kilowatt-hours per day.
The best times of the year to generate solar power at this location are during the summer and spring months when there's more sunshine and longer days.
To get the most out of your solar panels throughout the year, they should be installed at an angle facing 29 degrees South - this will help capture as much sunlight as possible over different seasons.
However, there could be local factors that might reduce how much energy your solar panels produce such as buildings or trees blocking sunlight from reaching your panels or dust and dirt reducing their efficiency by covering them up (which could be a concern given Lebanon's semi-arid climate). To mitigate these issues: make sure your panels are placed where they won't be shaded by other structures; regularly clean them to remove any dust or dirt; consider installing a tracking system so they always face towards the sun; use high-quality equipment designed for harsh conditions if necessary (like high temperatures).
In conclusion: Jounieh is a pretty good place for generating energy with solar PV systems - especially during summer and spring - but keep an eye out for local factors that might affect their performance like shading or dust build-up.
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 22 locations across Lebanon. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Jounieh
Seasonal solar PV output for Latitude: 33.983, Longitude: 35.6107 (Jounieh, Lebanon), 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 29° South in Jounieh, Lebanon
To maximize your solar PV system's energy output in Jounieh, Lebanon (Lat/Long 33.983, 35.6107) throughout the year, you should tilt your panels at an angle of 29° 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 Jounieh, Lebanon
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 Jounieh, Lebanon. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 18° South in Summer | 38° South in Autumn | 48° South in Winter | 26° 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 Jounieh, Lebanon
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 Jounieh, Lebanon.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Jounieh, Lebanon
Jounieh, Lebanon is located on the Mediterranean coastline, flanked by a steep hillside to the east. The area is known for its beautiful bay and mountain views. It lies directly north of the capital Beirut and south of Byblos.
The topography varies greatly within a relatively small area, ranging from sea level at the coast to high elevations in the nearby mountains. The terrain is generally rugged and rocky with narrow coastal plains next to steep cliffs that rise towards Mount Lebanon.
For large-scale solar PV installations, flat or gently sloping areas are most suitable as they minimize installation costs and maximize efficiency. Given this, potential locations around Jounieh could include:
1. Coastal Areas: While space may be limited due to urban development along the coast, any available flat or gently sloping areas could be suitable for solar PV installations.
2. Mountain Plateaus: Some plateaus in the surrounding mountains might provide enough space for large-scale installations if they receive sufficient sunlight throughout the year.
3. Rooftops: In densely populated urban areas like Jounieh itself or Beirut to its south, rooftop solar installations can be an effective way to generate electricity without requiring additional land resources.
However, any decision about where exactly to place such an installation would need careful consideration of factors beyond just topography – including local climate conditions (e.g., hours of sunlight), existing infrastructure (e.g., power grid connections), environmental impacts (e.g., potential disruption to local ecosystems), and social factors (e.g., visual impact on landscapes).
