Quelimane, Zambezia Province, Mozambique, located at latitude -17.8765 and longitude 36.8861, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons characterized more by wet and dry periods than temperature variations.

Seasonal Solar Performance

Solar energy production in Quelimane shows notable variations across seasons. Summer stands out as the most productive period, with an impressive 7.13 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 6.60 kWh/day. Autumn sees a moderate decrease to 5.68 kWh/day, while winter experiences the lowest output at 4.73 kWh/day.

Optimal Installation Angle

For fixed solar panel installations in Quelimane, Zambezia Province, the ideal tilt angle to maximize year-round energy production is 16 degrees facing North. This angle has been calculated considering the location's specific solar elevation angles and weighted by daily photovoltaic potential.

Peak Generation Periods

The most favorable times for solar energy generation in Quelimane align with the dry season, typically from April to November. During these months, clearer skies and reduced cloud cover contribute to higher solar irradiance levels, boosting overall energy production.

Environmental Considerations

While Quelimane's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. High humidity levels, especially during the wet season (December to March), can slightly reduce panel efficiency. 2. Occasional tropical storms or cyclones may pose risks to solar installations. To mitigate these challenges, implementing robust mounting systems designed to withstand strong winds is crucial. Additionally, regular cleaning of panels to remove dust and salt accumulation, which is common in coastal areas like Quelimane, Zambezia Province, can help maintain optimal performance.

Conclusion

Overall, Quelimane presents a highly favorable location for solar PV installations. With proper planning and maintenance, the consistent sunlight throughout the year can be effectively harnessed, making solar energy a reliable and sustainable power source for this region of Mozambique.

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 Quelimane

Seasonal solar PV output for Latitude: -17.8765, Longitude: 36.8861 (Quelimane, 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 16° North in Quelimane, Mozambique

To maximize your solar PV system's energy output in Quelimane, Mozambique (Lat/Long -17.8765, 36.8861) throughout the year, you should tilt your panels at an angle of 16° 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 Quelimane, 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 Quelimane, Mozambique. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° North in Summer	24° North in Autumn	33° North in Winter	11° 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 Quelimane, 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 Quelimane, Mozambique.

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 Quelimane, Mozambique

The topography around Quelimane, Mozambique, is characterized by its coastal lowland setting. Located near the mouth of the Rio dos Bons Sinais (Good Signs River), Quelimane sits on a flat, low-lying plain that extends inland from the Indian Ocean. The surrounding landscape is predominantly flat, with minimal elevation changes for many kilometers in all directions. As you move away from the coast, the terrain gradually rises, but remains relatively level. The area is part of the Zambezi River delta region, which is known for its extensive floodplains and wetlands. These features contribute to the overall flat nature of the landscape, with occasional slight undulations rather than significant hills or mountains.

Suitability for Large-Scale Solar PV

When considering areas nearby Quelimane for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain in the region is generally favorable for solar PV development, as it minimizes the need for extensive land preparation and allows for efficient panel layout. The most suitable areas for large-scale solar PV would be found inland from Quelimane, moving away from the immediate coastal zone. These inland areas offer several advantages: Firstly, they are less prone to flooding and have slightly higher elevations, which can help protect valuable solar infrastructure from potential coastal inundation or storm surges. Secondly, moving inland reduces exposure to salt spray from the ocean, which can be corrosive to solar panels and other equipment over time. Thirdly, inland areas are likely to have more open, unobstructed spaces that receive consistent sunlight throughout the day, without interference from coastal weather patterns or sea breezes that might bring increased cloud cover. The regions to the west and northwest of Quelimane, where the landscape transitions from coastal lowlands to slightly more elevated terrain, could be particularly well-suited for solar PV development. These areas may offer a good balance of flat, open land with reduced flood risk and optimal sun exposure. However, it's important to note that site-specific surveys would be necessary to determine the most suitable locations, taking into account factors such as local soil conditions, access to infrastructure, and proximity to the electrical grid. Additionally, environmental impact assessments would be crucial to ensure that large-scale solar developments do not adversely affect the sensitive ecosystems of the Zambezi delta region.
