Solar PV Analysis of Nampula, Mozambique
Nampula, Mozambique is a good location for generating energy through solar PV systems all year round. This is due to its tropical climate where sunlight is consistent throughout most of the year. The amount of electricity that can be generated from each kilowatt (kW) of installed solar varies with the seasons: 7.24 kWh/day in Summer, 5.34 kWh/day in Autumn, 5.20 kWh/day in Winter and 7.12 kWh/day in Spring.
The best times to generate solar power at this location are during the Summer and Spring when the output per kW installed is highest; however, even during Autumn and Winter, Nampula still has respectable output levels making it a viable location for year-round solar energy production.
For fixed panel installations at this location, tilting panels at an angle of 13 degrees North would maximize total annual production from these solar PV systems.
As for potential impediments to generating solar power here, while Nampula's tropical climate provides consistent sunlight most of the time which is ideal for solar energy generation, it also means there could be periods of heavy rainfall particularly during wet seasons that might cause temporary reductions in sunlight intensity or duration leading to lower energy outputs on those days.
Preventative measures could include installing sturdy mounts and supports to withstand strong wind conditions often associated with heavy rainfalls as well as using high-quality panels designed to perform well under varying weather conditions including rainy periods - these can help ensure greater overall performance consistency and reliability from your system irrespective of seasonal changes or occasional bad weather events.
In conclusion then: While there may be some minor challenges due mainly to seasonal variations and occasional inclement weather conditions associated with its tropical climate; overall Nampula offers very good potential as a site for producing reliable amounts of clean renewable power using Solar PV technology all-year-round.
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 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 Nampula
Seasonal solar PV output for Latitude: -15.1185, Longitude: 39.2695 (Nampula, 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 13° North in Nampula, Mozambique
To maximize your solar PV system's energy output in Nampula, Mozambique (Lat/Long -15.1185, 39.2695) throughout the year, you should tilt your panels at an angle of 13° 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 Nampula, 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 Nampula, Mozambique. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° South in Summer | 21° North in Autumn | 31° North in Winter | 8° 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 Nampula, 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 Nampula, 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 Nampula, Mozambique
Nampula is located in northern Mozambique and is characterized by a mix of coastal lowlands, plateaus, and highlands. The region generally has an undulating topography with some flat areas suitable for agriculture or other developments. It's surrounded by the Niassa province to the north, Cabo Delgado and Zambezia provinces to the east, and Nampula Province on its south.
Considering large-scale installations, it would be most suited in areas that have relatively flat terrain for easy installation and maintenance of equipment. These could potentially be found in the lower-lying coastal plains around Nampula or cleared agricultural lands that are not currently under cultivation.
However, suitability isn't determined solely by topography but also factors like temperature (since extreme heat can reduce efficiency), proximity to power grids or demand centers (for ease of transmission), land use constraints among others. Therefore a comprehensive feasibility study which includes these factors would be required to identify specific sites within Nampula region that are best suited for large scale installations.
