Solar PV Analysis of Maputo, Mozambique
Maputo, Mozambique, located in the Southern Sub Tropics, is a pretty good spot for generating solar energy all year round. The amount of energy you can get from a kilowatt of solar power varies throughout the year. In summer you can expect about 6.14 kilowatt-hours per day, in autumn it's about 5.48 kilowatt-hours per day, in winter it drops to 4.31 kilowatt-hours per day and then goes back up to 5.71 kilowatt-hours per day in spring.
This means that summer and spring are the best times for solar power generation at this location due to longer daylight hours and higher sun intensity compared to other seasons.
To make sure you're getting as much solar energy as possible throughout the year, your panels should be tilted at an angle of 24 degrees facing north if they're fixed installations (meaning they don't move). This is because Maputo is located south of the equator so tilting panels towards north will ensure that they face towards the sun most directly across all seasons.
As with any location though there could be local factors which might affect how much energy you can generate from your solar panels. These could include environmental issues like dust or dirt on your panels which would block sunlight; topography or physical features like mountains or buildings that could cast shadows on your panels; weather conditions such as heavy cloud cover or rainfall; and other local factors like legislation or regulations affecting where and how you can install your panels.
For example, Maputo has a tropical savanna climate which means it experiences a wet season from November through April which may reduce sunlight availability due to increased cloud cover during these months.
To ensure greater energy production despite these potential challenges:
1) Regular cleaning of panels will help remove any dirt or dust build-up.
2) If possible choose an installation site away from large obstructions (like buildings or trees) that could cast shadows on your panels.
3) Weather resistant solar panels can help ensure performance during heavy rain or other adverse weather conditions.
4) Finally, it's important to understand and comply with any local regulations about where and how you can install your solar panels.
In summary, Maputo, Mozambique is a pretty good location for year-round solar energy generation but care must be taken to optimize the installation and maintenance of your solar system.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 7 locations across Mozambique. 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 Maputo
Seasonal solar PV output for Latitude: -25.9707, Longitude: 32.601 (Maputo, Mozambique), 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 24° North in Maputo, Mozambique
To maximize your solar PV system's energy output in Maputo, Mozambique (Lat/Long -25.9707, 32.601) throughout the year, you should tilt your panels at an angle of 24° North 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 Maputo, Mozambique
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 Maputo, Mozambique. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° North in Summer | 32° North in Autumn | 42° North in Winter | 20° North 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 Maputo, Mozambique
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 Maputo, Mozambique.
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 Maputo, Mozambique
Maputo, the capital of Mozambique, is located in the far south of the country on the coast. The city itself is relatively flat and low-lying. It is situated on a large natural harbor and surrounded by estuaries and wetlands to the north and east.
The topography around Maputo includes coastal plains, with some hills further inland. To the west of Maputo, terrain gradually rises towards higher ground which forms part of a plateau region that covers much of southern Africa.
In terms of solar PV potential, areas with flat or gently sloping terrain would be most suitable as they allow for easier installation and maintenance of solar panels. Given this criteria, coastal plains around Maputo could be considered for large-scale solar PV projects.
However, it's also important to consider factors such as sunlight intensity (solar irradiance), local weather conditions (e.g., cloud cover), land use (e.g., agriculture vs wilderness) and proximity to infrastructure (e.g., power grids).
Mozambique has high levels of solar irradiation throughout the year which makes it ideal for solar energy production. The regions north-west from Maputo may provide suitable locations due to their relatively flat topography combined with lower population density compared to urban areas like Maputo itself.
It should also be noted that environmental impact assessments would need to be conducted before any large-scale project can proceed in order to minimize any potential negative effects on local ecosystems or communities.
