Solar PV Analysis of Tlemcen, Algeria
Based on the data given, Tlemcen, Algeria is a fairly good location for generating solar energy throughout the year. The amount of electricity produced from solar panels varies with each season. During summer and spring, you can expect to generate more electricity - 7.91 kilowatt-hours (kWh) per day in summer and 6.53 kWh/day in spring per kilowatt (kW) of installed solar panel capacity. In autumn and winter, the output drops to 5.10 kWh/day and 3.80 kWh/day respectively.
This means that the best times to generate solar power at this location are during the longer daylight hours of summer and spring when sunlight is most abundant.
For optimal results from your solar installation at this location, it's recommended that panels be tilted at an angle of 31 degrees facing southwards. This positioning allows them to capture maximum sunlight over the course of a year.
However, there could be local factors such as weather conditions or environmental issues that might affect how much energy you can produce using solar panels in Tlemcen. For example, dust storms common in desert areas like Algeria could cover your panels reducing their effectiveness or heavy rainfall could damage them if not properly protected.
To prevent these potential issues from impacting your energy production:
- Regular cleaning can help remove dust or dirt accumulation on your panels.
- Proper installation by professionals ensures they will withstand harsh weather conditions including heavy rains.
- Using high-quality materials for both panel construction and installation helps ensure durability under different environmental conditions.
In conclusion: While there may be challenges due to local factors such as weather conditions or environment-related issues affecting power generation efficiency; with proper care, maintenance and quality materials used during installation; Tlemcen seems like a beneficial place for producing renewable energy using photovoltaic cells throughout most parts of the year especially during Spring & Summer seasons based on data provided above regarding expected daily outputs per kW installed.
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 52 locations across Algeria. 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 Tlemcen
Seasonal solar PV output for Latitude: 34.8992, Longitude: -1.2874 (Tlemcen, Algeria), 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 31° South in Tlemcen, Algeria
To maximize your solar PV system's energy output in Tlemcen, Algeria (Lat/Long 34.8992, -1.2874) throughout the year, you should tilt your panels at an angle of 31° 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 Tlemcen, Algeria
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 Tlemcen, Algeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 19° South in Summer | 40° South in Autumn | 50° South in Winter | 27° 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 Tlemcen, Algeria
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 Tlemcen, Algeria.
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 Tlemcen, Algeria
Tlemcen, Algeria is located in the northwestern part of the country near the border with Morocco. The topography of this region is characterized by a mix of mountains, plateaus, and plains. The city itself sits on the slopes of Lalla Setti Mountain and is surrounded by other peaks such as Tafna and Jebel Tessala.
The region experiences a Mediterranean climate with hot, dry summers and mild, wet winters which can be suitable for solar PV installations.
For large-scale solar photovoltaic (PV) projects, flat or gently sloping areas are typically preferred because they require less site preparation work than hilly or mountainous terrains. The plains around Tlemcen could potentially be suited for such projects.
However, factors like solar irradiance levels (which tend to be high in Algeria), land availability and use restrictions (such as protected natural areas or agricultural lands), proximity to power transmission lines and infrastructure would also need to be considered when identifying suitable sites for large-scale solar PV projects.
Additionally, desert regions in Algeria generally have higher sunlight intensity compared to coastal regions like Tlemcen. Therefore southern parts of Algeria might offer more potential for large scale Solar PV installations than northern regions.
Nonetheless specific feasibility studies considering all these factors need to be conducted before deciding on locations for largescale Solar PV installations.
Algeria solar PV Stats as a country
Algeria ranks 53rd in the world for cumulative solar PV capacity, with 448 total MW's of solar PV installed. Each year Algeria is generating 10 Watts from solar PV per capita (Algeria ranks 73rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Algeria?
Yes, there are incentives for businesses wanting to install solar energy in Algeria. The Algerian government has implemented a number of policies and programs to encourage the development of renewable energy sources, including solar energy. These include tax exemptions, subsidies, and other financial incentives for businesses that invest in renewable energy projects. Additionally, the government has established a Renewable Energy Development Fund (REDF) which provides grants and loans to support renewable energy projects.
