Tamale, Ghana is a great location for generating solar energy all year round. This area gets consistent sunlight throughout the year and has seasons that are mostly characterized by wet and dry periods. The amount of electricity you can expect to generate from each kilowatt (kW) of installed solar power varies slightly by season: you'll get about 5.24 kilowatt hours (kWh) per day in summer, 5.97 kWh/day in autumn, 5.95 kWh/day in winter, and 6.36 kWh/day in spring.

So when is the best time to generate solar power here? Well, it's pretty good all year round but spring seems to be the most ideal season as it has the highest daily output at 6.36 kWh.

If you're planning on installing fixed solar panels here, tilting them at an angle of around 9 degrees south will help maximize your total yearly production from these panels.

Now let's talk about potential obstacles to producing solar energy here – things like environmental or weather factors that could interfere with your system's performance.

One major concern could be dust or dirt accumulation on your panels during the dry season which can reduce their efficiency significantly. Regular cleaning would ensure they continue operating optimally.

Another issue might be heavy rainfall during the wet season which may damage installations if not properly protected or designed for such conditions; proper installation techniques and use of durable materials can mitigate this risk though.

Overall Tamale offers great potential for harnessing solar energy due its consistent sunlight exposure; with careful consideration given to local environmental conditions one should have a successful operation there.

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.

Seasonal solar PV output for Latitude: 9.4034226, Longitude: -0.842416 (Tamale, 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:

Average 5.24kWh/day in Summer.

Average 5.97kWh/day in Autumn.

Average 5.95kWh/day in Winter.

Average 6.36kWh/day in Spring.

Ideally tilt fixed solar panels 9° South in Tamale, Ghana

To maximize your solar PV system's energy output in Tamale, Ghana (Lat/Long 9.4034226, -0.842416) throughout the year, you should tilt your panels at an angle of 9° 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.

At Latitude: 9.4034226, Longitude: -0.842416, the ideal angle to tilt panels is 9° South

Seasonally adjusted solar panel tilt angles for Tamale, 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 Tamale, Ghana. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° South 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 Tamale, 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 Tamale, Ghana.

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 Tamale, Ghana

Tamale, Ghana is located in the Northern Region of the country. The topography of this region is relatively flat with an average elevation of about 150 meters above sea level. It is characterized by savannah grasslands and sparse tree vegetation.

This flat terrain makes it ideal for large-scale solar photovoltaic (PV) installations as there are minimal obstructions to sunlight. Additionally, Tamale has a tropical climate with high temperatures and abundant sunshine throughout the year, further enhancing its suitability for solar energy production.

Areas nearby that would be most suited to large-scale solar PV include:

1. Savelugu: This town lies north-east of Tamale and shares similar geographical features which make it suitable for such projects.
2. Yendi: Located east of Tamale, Yendi also has a largely flat landscape ideal for setting up large scale PV systems.
3. Tolon/Kumbungu District: This district lies west of Tamale and could also be considered due to its favorable topography.

However, before embarking on any large-scale project, factors like land ownership rights, proximity to electrical grid infrastructure for power transmission/distribution should also be taken into consideration along with environmental impact assessments.

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.
