Graph of hourly avg kWh electricity output per kW of Solar PV installed in Juba, South Sudan (by season)

Juba, Central Equatoria, South Sudan is a pretty good location for generating solar energy all year round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. Seasons here are usually marked by wet and dry periods rather than big temperature changes.

The amount of energy you can expect to generate from each kilowatt (kW) of installed solar panels varies slightly with the seasons. You'll get about 5.61 kilowatt-hours (kWh) per day in Summer, 6.10 kWh/day in Autumn, 6.53 kWh/day in Winter and 6.26 kWh/day in Spring.

If you're installing fixed solar panels at this location, the best angle to tilt them for maximum production all year round is 5 degrees facing South.

However, there could be some local factors that might affect how much energy you can produce from your solar panels:

1) Weather: Although Juba has a lot of sunshine, it also has a rainy season which may reduce solar production during those months due to cloud cover.

2) Dust: Juba can sometimes experience dust storms which may cover your panels and reduce their efficiency unless they are regularly cleaned.

3) Topography: If there are hills or other tall structures nearby that cast shadows on your panels at certain times of day or year, this could also reduce their output.

To deal with these challenges:

1) For weather-related issues like rain or clouds reducing sunlight exposure on your panels during certain seasons - unfortunately there's not much you can do about this except install more panels to compensate for those less sunny periods if feasible financially.

2) For dust - regular cleaning of your solar panel surfaces would help ensure they remain efficient.

3) For topography issues like shadows cast by hills or buildings - careful planning when choosing where to install your system will be crucial so as to avoid such obstructions as much as possible.

So, in conclusion, Juba is a pretty good location for solar energy generation year-round, but you'll need to plan carefully and be prepared for some challenges due to weather and local conditions.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 8 locations across South Sudan. 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 Juba

Seasonal solar PV output for Latitude: 4.8499, Longitude: 31.5812 (Juba, South Sudan), 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:

Summer
Average 5.61kWh/day in Summer.
Autumn
Average 6.10kWh/day in Autumn.
Winter
Average 6.53kWh/day in Winter.
Spring
Average 6.26kWh/day in Spring.

 

Ideally tilt fixed solar panels 5° South in Juba, South Sudan

To maximize your solar PV system's energy output in Juba, South Sudan (Lat/Long 4.8499, 31.5812) throughout the year, you should tilt your panels at an angle of 5° 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.

At Latitude: 4.8499, Longitude: 31.5812, the ideal angle to tilt panels is 5° South

Seasonally adjusted solar panel tilt angles for Juba, South Sudan

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 Juba, South Sudan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° South tilt angle throughout the year.

Overall Best Summer Angle Overall Best Autumn Angle Overall Best Winter Angle Overall Best Spring Angle
11° North in Summer 11° South in Autumn 21° South in Winter 1° North in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Juba, South Sudan as follows: In Summer, set the angle of your panels to 11° facing North. In Autumn, tilt panels to 11° facing South for maximum generation. During Winter, adjust your solar panels to a 21° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 1° angle facing North to capture the most solar energy in Juba, South Sudan.

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 Juba, South Sudan

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 Juba, South Sudan.

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 Juba, South Sudan

Juba, the capital city of South Sudan, is situated in the southern part of the country. The topography around Juba is generally flat with some undulating hills. The area lies near the White Nile River and has a tropical savannah climate with long periods of hot weather and heavy rainfall during rainy seasons.

For large-scale solar PV installations, you would ideally want an area that has high levels of sunlight (solar irradiance), flat or gently sloping terrain for easier installation and maintenance, and access to infrastructure for power transmission.

Given these criteria, areas outside Juba city where there are wide open spaces would be suitable for solar PV installations. The relatively flat terrain would make installation easier while also allowing for efficient capture of sunlight. Additionally, South Sudan receives a significant amount of sunlight throughout the year which makes it ideal for solar energy production.

However, feasibility studies should be conducted to assess other factors such as soil type (for ground-mounted systems), proximity to power grids or demand centers (to reduce transmission losses/costs), potential environmental impacts among others before deciding on a specific location.

It's also important to note that political stability and security situation should be considered as they can affect construction and operation phases significantly in regions like South Sudan.
