Bulawayo, Zimbabwe, is a suitable location for generating solar energy throughout the year due to its tropical climate with consistent sunlight. The amount of electricity that can be produced from each kilowatt of installed solar varies slightly by season: 6.24 kWh/day in Summer, 6.52 kWh/day in Autumn, 5.40 kWh/day in Winter and 6.75 kWh/day in Spring.

The best times to generate solar power at this location are during Autumn and Spring when the output is highest per day; however, even during Winter (the least productive season), the output remains relatively high compared to many non-tropical locations.

For fixed panel installations at this location, tilting panels towards an angle of 19 degrees North would maximize total annual production from the solar PV system.

There could be some local factors that might affect solar production at this location such as dust storms or heavy rainfall which could cover panels reducing their efficiency. However these events are not common enough to significantly impact overall performance.

To ensure greater energy production despite these potential obstacles, regular maintenance including cleaning of panels can help keep systems running efficiently. It's also beneficial to install durable panels designed for withstanding harsh weather conditions if they occur occasionally.

In summary Bulawayo offers good conditions for generating electricity via Solar PV throughout most of the year but regular maintenance will help ensure optimal performance despite occasional adverse weather 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 6 locations across Zimbabwe. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Average 5.40kWh/day in Winter.

Average 6.75kWh/day in Spring.

Ideally tilt fixed solar panels 19° North in Bulawayo, Zimbabwe

To maximize your solar PV system's energy output in Bulawayo, Zimbabwe (Lat/Long -20.1452, 28.5889) throughout the year, you should tilt your panels at an angle of 19° 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.

At Latitude: -20.1452, Longitude: 28.5889, the ideal angle to tilt panels is 19° North

Seasonally adjusted solar panel tilt angles for Bulawayo, Zimbabwe

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 Bulawayo, Zimbabwe. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.

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 Bulawayo, Zimbabwe

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 Bulawayo, Zimbabwe.

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 Bulawayo, Zimbabwe

Bulawayo, Zimbabwe is located in the southwestern part of the country. The topography around Bulawayo is primarily composed of a plateau with an average elevation of about 1,340 meters above sea level. The region is relatively flat with some undulating hills and rocky outcrops.

The climate in this area is semi-arid, receiving less rainfall compared to the northern parts of Zimbabwe. It has a significant amount of sunny days throughout the year making it suitable for solar PV installations.

For large-scale solar PV projects, areas that are flat and open would be most suitable since they provide maximum exposure to sunlight and ease installation process. In addition, these locations should ideally be close to existing power infrastructure for easier integration into the grid.

Around Bulawayo, potential areas could include expanses towards its south-eastern side which appear to have larger tracts of undeveloped land or potentially repurposing underutilized lands within city limits itself. However, any such project would require thorough site-specific investigations including environmental impact assessments before proceeding.
