Kadoma, Zimbabwe, situated at latitude -18.3338861 and longitude 29.914183, presents a favorable location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily distinguished by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

Solar panel efficiency in Kadoma demonstrates strong performance across all seasons. Spring stands out as the most productive period, with an impressive daily output of 7.18 kWh per kW of installed capacity. Summer and autumn follow closely, generating 6.52 kWh/day and 6.59 kWh/day respectively. Even during winter, the least productive season, panels still produce a respectable 5.65 kWh/day. This consistent year-round performance makes Kadoma an excellent location for solar energy projects. The relatively small variation between seasons ensures a stable power supply throughout the year, reducing the need for supplementary energy sources during less productive periods.

Optimal Panel Placement

To maximize solar energy capture in Kadoma, fixed solar panels should be tilted at an 18-degree angle facing north. This optimal angle has been calculated to ensure the highest possible year-round energy production, taking into account the Earth's elliptical orbit and the site's specific latitude.

Environmental Considerations

While Kadoma's climate is generally conducive to solar energy production, there are a few environmental factors to consider: 1. Dust and dirt accumulation: The region's dry seasons can lead to increased dust in the air, which may settle on solar panels and reduce their efficiency. 2. Heavy rainfall: During the wet season, intense rain showers could temporarily reduce solar output. To mitigate these issues, regular cleaning of solar panels is recommended, especially during and after the dry season. Additionally, installing panels at the optimal angle helps with natural cleaning during rainy periods. Robust mounting systems should be used to withstand potential strong winds associated with heavy rainfall. In conclusion, Kadoma's location offers excellent potential for solar energy generation throughout the year. With proper installation and maintenance, solar PV systems in this area can provide a reliable and efficient source of renewable energy.

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.

Solar output per kW of installed solar PV by season in Kadoma

Seasonal solar PV output for Latitude: -18.3338861, Longitude: 29.914183 (Kadoma, Zimbabwe), 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 18° North in Kadoma, Zimbabwe

To maximize your solar PV system's energy output in Kadoma, Zimbabwe (Lat/Long -18.3338861, 29.914183) throughout the year, you should tilt your panels at an angle of 18° 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 Kadoma, 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 Kadoma, Zimbabwe. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° 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	34° North in Winter	12° 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 Kadoma, 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 Kadoma, 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 Kadoma, Zimbabwe

The topography around Kadoma, Zimbabwe, is characterized by gently rolling terrain typical of the country's central plateau region. This area, known as the Midlands, features a mix of flat plains and low, undulating hills. The landscape is predominantly savanna, with scattered trees and grassy expanses stretching across the horizon. Kadoma itself sits at an elevation of approximately 1,160 meters (3,800 feet) above sea level. The surrounding area gradually slopes downward towards the north and east, while slightly higher ground can be found to the south and west. Small streams and rivers crisscross the region, creating shallow valleys and occasional rocky outcrops.

Suitable Areas for Large-Scale Solar PV

The areas most suited to large-scale solar photovoltaic (PV) installations near Kadoma would be the relatively flat, open spaces to the north and east of the city. These locations offer several advantages for solar energy development: Firstly, the terrain in these directions is generally flatter, which reduces the cost and complexity of site preparation for solar panel arrays. The absence of significant hills or mountains also minimizes the risk of shading, allowing for optimal sun exposure throughout the day. Secondly, these areas typically have fewer trees and less dense vegetation, which means less clearing would be required for installation. This not only reduces environmental impact but also lowers initial development costs. Thirdly, the proximity to Kadoma itself is beneficial for infrastructure purposes. The existing road network and electrical grid connections in the vicinity of the city would facilitate easier transportation of materials and integration of the generated power into the local energy system. Lastly, the climate in this region is generally sunny and dry for much of the year, providing excellent conditions for solar power generation. The relatively high elevation of the Midlands also contributes to clearer skies and potentially higher solar radiation levels. It's important to note that while these areas show promise for solar PV development, detailed site assessments would be necessary to determine the most suitable specific locations. Factors such as land ownership, environmental considerations, and proximity to wildlife habitats would need to be carefully evaluated before any large-scale solar projects could be implemented.
