Solar PV Analysis of Tripoli, Lebanon
Located at latitude 34.4301 and longitude 35.8476, Tripoli in Lebanon is an advantageous site for solar photovoltaic (PV) installations due to its substantial average daily energy production per kilowatt of installed solar capacity across all four seasons. During the summer, each kilowatt of installed solar power can generate an average of 8.40 kWh per day, while autumn yields about 5.06 kWh/day per kW, winter presents a lower yet still significant yield of approximately 3.25 kWh/day per kW and spring offers around 6.92 kWh/day per kW.
The high energy generation during the summer months reflects the abundant sunlight available in this period; however, even in less sunny seasons like winter or autumn, the energy production is still considerable thanks to Tripoli's geographical position that benefits from good sun exposure year-round.
For a fixed panel installation in Tripoli, tilting panels at an angle of approximately 29 degrees towards South will optimize their exposure to sunlight and consequently maximize their power output.
While Tripoli’s geographic location favors solar energy production overall, it's important to consider certain local environmental factors that may impact this potential advantageously or adversely. For instance, strong winds or dust storms could obstruct sunlight penetration and subsequently reduce PV system performance by causing soiling on panel surfaces which decreases their efficiency.
In order to mitigate these potential impediments and ensure optimal energy generation throughout the year despite these challenges, it would be beneficial to incorporate regular maintenance practices such as routine cleaning of panels into your operational plan for your PV installation at this location when planning your project.
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 Tripoli
Seasonal solar PV output for Latitude: 34.4301, Longitude: 35.8476 (Tripoli, 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 Tripoli, Lebanon
To maximize your solar PV system's energy output in Tripoli, Lebanon (Lat/Long 34.4301, 35.8476) 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 Tripoli, 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 Tripoli, 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 | 39° South in Autumn | 49° 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 Tripoli, 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 Tripoli, 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 Tripoli, Lebanon
The topography around Tripoli, Lebanon is mostly flat. The terrain is largely composed of coastal plains and hills, with some small mountains in the north and east. The area has a Mediterranean climate with mild winters and hot summers.
The most suitable areas for large-scale solar PV near Tripoli would be on the flat coastal plains and hills as they receive more direct sunlight than mountainous regions. Additionally, these areas have minimal obstructions such as trees or buildings which can reduce the amount of sunlight available to solar panels.
