Solar PV Analysis of Yendi, Ghana
Yendi, Ghana is a location that is very suitable for generating solar energy throughout the year. This is because it's situated in the tropics where sunlight is consistent for most of the year. The amount of electricity that can be generated from each kilowatt (kW) of installed solar panels varies slightly with each season but remains relatively high all year round: 5.24 kilowatt-hours per day (kWh/day) in summer, 5.97 kWh/day in autumn, 5.95 kWh/day in winter and 6.36 kWh/day in spring.
The best time to generate solar power at this location would be during spring when the output reaches its peak at 6.36 kWh per day for every kW of installed solar panels.
For a fixed panel installation at this location, tilting the panels at an angle of 10 degrees South would maximize total annual production from these panels.
However, there could be some local factors that might affect solar production here such as dust or dirt accumulation on the panels which could block sunlight and reduce efficiency; heavy rainfall which may damage equipment; and potential theft or vandalism due to lack of security measures.
To overcome these issues:
1) Regular cleaning and maintenance should be carried out to remove any dust or dirt on the panels.
2) Weather-resistant materials should be used for construction and appropriate protection measures taken against heavy rains.
3) Adequate security measures should also be put into place to prevent theft or vandalism.
In conclusion, Yendi, Ghana provides an excellent environment for harnessing solar energy throughout the year with only minor concerns which can easily be addressed through regular maintenance and proper protective measures.
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 12 locations across Ghana. 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 Yendi
Seasonal solar PV output for Latitude: 9.4450438, Longitude: -0.0093266 (Yendi, Ghana), 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 10° South in Yendi, Ghana
To maximize your solar PV system's energy output in Yendi, Ghana (Lat/Long 9.4450438, -0.0093266) throughout the year, you should tilt your panels at an angle of 10° 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 Yendi, Ghana
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 Yendi, Ghana. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° North in Summer | 16° South in Autumn | 25° South in Winter | 3° 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 Yendi, Ghana
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 Yendi, Ghana.
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 Yendi, Ghana
The topography around Yendi, Ghana is generally flat and characterized by savannah plains. This area also experiences a tropical climate with two distinct seasons: the rainy season and dry season. The annual average temperature is about 28 degrees Celsius.
Given these characteristics, the region would be highly suitable for large-scale solar photovoltaic (PV) installations due to its high solar irradiation levels and lack of physical obstructions like mountains or forests that could block sunlight.
Large expanses of flat land are ideal for setting up solar farms as they allow for easy installation and maintenance of solar panels. Furthermore, the high temperatures can contribute to increased efficiency in electricity production since PV technology relies on sunlight.
However, it's important to note that while high temperatures can increase efficiency, extremely high temperatures might have an adverse effect on the performance of PV modules. Therefore, appropriate cooling measures should be considered in design stages.
In terms of specific areas near Yendi that are suitable for large-scale solar PV installations, this would require a more detailed analysis considering factors like land use patterns (availability of unused lands), proximity to transmission lines or grids for ease of connectivity etc., which isn't possible without further data. However theoretically speaking any nearby areas with similar topographical features and climatic conditions as Yendi could potentially be suited for such projects.
Ghana solar PV Stats as a country
Ghana ranks 85th in the world for cumulative solar PV capacity, with 108 total MW's of solar PV installed. Each year Ghana is generating 3 Watts from solar PV per capita (Ghana ranks 83rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Ghana?
Yes, there are several incentives for businesses wanting to install solar energy in Ghana. The government of Ghana has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power. These include tax exemptions, subsidies, and grants for businesses that install solar systems. Additionally, the government has established a Renewable Energy Fund which provides financial support for projects related to renewable energy development. Finally, the government also offers technical assistance and capacity building services to help businesses develop their own solar projects.
