Mararaba, Nasarawa, Nigeria is a very good location for generating energy through solar panels all year round. This is because it's located in the Tropics where sunlight is pretty much consistent throughout most of the year. The seasons here are often defined by wet and dry periods rather than significant changes in temperature or sunlight.

Now, when we talk about how much electricity you can expect to generate from each kilowatt (kW) of solar power installed at this location, it varies a bit with the season but remains high overall. In Summer, you can expect around 4.81 kilowatt-hours (kWh) per day for each kW installed; in Autumn and Winter, this increases to around 6 kWh/day; and in Spring, it's slightly higher still at about 6.39 kWh/day.

To get the most out of your solar panels over the course of a year at this location, they should ideally be tilted at an angle facing 10 degrees South.

However, there could be some local factors that might affect how well your solar panels work here. For example:

- During the wet season there might be more cloud cover which could reduce how much sunlight reaches your panels.
- Dust or dirt build-up on your panel surfaces could also decrease their efficiency.

To counter these potential issues:

- Regular cleaning and maintenance will help ensure dust or dirt doesn't build up on your panels.
- You might want to consider adjustable mounts for your panels so that you can change their angle depending on the time of year – tilting them more towards the sun during times when there's likely to be more cloud cover may help increase their output.

So overall Mararaba looks like an excellent place for installing solar PVs due its consistent sunlight exposure throughout most parts of the year!

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 50 locations across Nigeria. 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 Mararaba

Seasonal solar PV output for Latitude: 9.0266823, Longitude: 7.6073554 (Mararaba, Nigeria), 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 4.81kWh/day in Summer.

Average 6.00kWh/day in Autumn.

Average 6.38kWh/day in Winter.

Average 6.39kWh/day in Spring.

Ideally tilt fixed solar panels 10° South in Mararaba, Nigeria

To maximize your solar PV system's energy output in Mararaba, Nigeria (Lat/Long 9.0266823, 7.6073554) 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.

At Latitude: 9.0266823, Longitude: 7.6073554, the ideal angle to tilt panels is 10° South

Seasonally adjusted solar panel tilt angles for Mararaba, Nigeria

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 Mararaba, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° 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 Mararaba, Nigeria

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 Mararaba, Nigeria.

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 Mararaba, Nigeria

Mararaba is located in the Nasarawa State of Nigeria. The area around Mararaba has a mixed topography, with some flat plains and hilly areas. The region is part of the Nigerian savannah, which means it's generally flat with scattered trees and shrubs.

For large-scale solar PV installations, flat or gently sloping terrain is preferred to minimize installation costs and maximize sun exposure. Areas that are free from excessive dust, soiling or shading should also be prioritized.

In terms of specific locations near Mararaba for potential large-scale solar PV projects:

1) Flat agricultural lands around the town could potentially be suitable for solar development due to their open space and sun exposure.

2) Areas along major roadways such as Abuja-Keffi Road might also be suitable due to their accessibility.

3) Unused industrial land can also serve as a good site since they are usually already cleared and leveled.

However, any proposed site would need to undergo a detailed assessment including factors like local climate conditions (e.g., annual sunlight hours), existing land use, proximity to power grid infrastructure, environmental impacts etc.
