The location of Warder, Somali, Ethiopia, is quite good for generating energy through solar power year-round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. The changes in seasons here are more about wet and dry periods rather than significant variations in temperature or daylight hours.
In terms of how much electricity you can expect to generate from each kilowatt (kW) of installed solar panels, it varies a bit depending on the season. In summer, you would get around 6.41 kilowatt-hours (kWh) per day for each kW of solar panels installed. This increases slightly in autumn to 6.81 kWh/day, then again in winter to 7.26 kWh/day and finally drops a little bit to 7.10 kWh/day during spring.
This means that while you can generate useful amounts of power all year round at this location, your best times for doing so will be during autumn and winter when output levels are highest.
If you're installing fixed-panel solar installations at this location, tilting them at an angle of seven degrees towards the south will give you the best overall production across the entire year.
However, there could be local factors that might affect your ability to produce solar power here - weather conditions like heavy rainfall or dust storms could reduce panel efficiency by blocking sunlight; local wildlife might also damage panels if not properly protected; additionally high temperatures may reduce panel efficiency as well.
To prevent these issues: regular cleaning and maintenance can help keep your panels clear from dust or other obstructions; protective measures such as fencing or covers might be needed against potential wildlife interference; installing cooling mechanisms or choosing heat-resistant panel models could help combat efficiency loss due to high temperatures.
As always with renewable energy projects like this one though - it's important to carefully consider all these factors before making any final decisions about whether or not this location would be right for your specific needs and circumstances.
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 24 locations across Ethiopia. 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 Warder
Seasonal solar PV output for Latitude: 6.9754, Longitude: 45.3383 (Warder, Ethiopia), 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 7° South in Warder, Ethiopia
To maximize your solar PV system's energy output in Warder, Ethiopia (Lat/Long 6.9754, 45.3383) throughout the year, you should tilt your panels at an angle of 7° South 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 Warder, Ethiopia
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 Warder, Ethiopia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° North in Summer | 13° South in Autumn | 23° South in Winter | 1° South 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 Warder, Ethiopia
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 Warder, Ethiopia.
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 Warder, Ethiopia
Warder, Ethiopia is located in the Somali Region of eastern Ethiopia. The topography around Warder is largely flat to gently undulating with some hills and valleys. The area is semi-arid, characterized by savannah grasslands and sparse vegetation.
The flat terrains and high levels of sunlight make this region potentially suitable for large-scale solar PV installations. Particularly, the vast open grasslands could be ideal as they offer unobstructed exposure to sunlight.
However, a thorough feasibility study would need to be conducted before any commitment can be made. Factors such as local climate conditions (including cloud cover and rainfall), land ownership issues, grid accessibility, potential environmental impacts among others should all be considered in the evaluation process.
In addition to geographical suitability, socio-economic factors such as local demand for electricity or presence of energy-intensive industries could also influence where it might be most beneficial to locate a large-scale solar PV installation.
