Benin City, Edo State, Nigeria is a pretty good spot for generating solar power all year round. This city is located in the tropics where sunlight is pretty much consistent throughout the year. The seasons there are more about wet and dry periods rather than traditional four seasons we experience in many other parts of the world.

In terms of how much electricity you can expect to get from each kilowatt (kW) of installed solar panels, it varies slightly by season: In summer, you'll get around 4.39 kilowatt-hours (kWh) per day; in autumn, it's about 5 kWh per day; winter brings slightly more at 5.3 kWh/day; and spring gives roughly 5.25 kWh/day.

If you're thinking about when might be the best time to generate solar energy at this location, autumn through spring seems to be ideal because these times provide slightly higher daily output compared to summer.

Now if you're installing fixed panel solar systems here, tilting them at an angle of seven degrees towards south would give maximum energy production throughout the year.

However, like any other place on Earth, Benin City has its own local factors that could potentially hinder your solar production. One significant factor would be weather conditions - specifically during the wet season when cloud cover and rainfall may reduce sunlight exposure for your panels.

To counteract this issue and ensure greater energy production from your system despite these challenges:

1) Regular cleaning & maintenance: Keeping your panels clean especially during or after rainfalls will help maintain their efficiency.
2) Install a proper drainage system: This will prevent water accumulation which could damage your installation.
3) Use micro-inverters or power optimizers: These devices can help improve performance even under partial shading conditions.
4) If possible consider tracking systems which allow panels to move with sun’s position maximizing exposure even on cloudy days.

Overall though given its tropical location with consistent sunlight, Benin City is a pretty good spot for solar energy generation.

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 Benin City

Seasonal solar PV output for Latitude: 6.3332, Longitude: 5.6238 (Benin City, 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 4.39kWh/day in Summer.

Average 5.00kWh/day in Autumn.

Average 5.30kWh/day in Winter.

Average 5.25kWh/day in Spring.

Ideally tilt fixed solar panels 7° South in Benin City, Nigeria

To maximize your solar PV system's energy output in Benin City, Nigeria (Lat/Long 6.3332, 5.6238) 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.

At Latitude: 6.3332, Longitude: 5.6238, the ideal angle to tilt panels is 7° South

Seasonally adjusted solar panel tilt angles for Benin City, 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 Benin City, Nigeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° 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 Benin City, 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 Benin City, 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 Benin City, Nigeria

Benin City, Nigeria is situated in the southern part of the country and lies on a relatively flat terrain characterized by tropical rainforest vegetation. The city is located approximately 40 meters above sea level. It's surrounded by several rivers including the Ovia River to the east and south, Ikpoba River to the north and west, and smaller tributaries running through it.

Considering solar PV installation, areas with flat or gently sloping terrains would be most suitable as they provide maximum exposure to sunlight and are easier for installation. Given Benin City’s geographical location near the equator, it receives ample sunlight throughout the year making it an ideal location for large-scale solar PV installations.

However, factors like land availability, proximity to transmission lines or grids (for ease of power evacuation), local policies regarding land use for renewable energy projects should also be considered while choosing sites for large-scale solar PV projects.

In terms of specific locations around Benin City that could potentially host such installations: open lands outside densely populated urban areas; agricultural lands not currently under intense cultivation; or brownfield sites (abandoned industrial sites) could all be potential candidates subject to detailed feasibility studies including environmental impact assessments.

The high rainfall in this region may pose some challenges due its effect on irradiance levels but modern solar panels can still generate electricity during cloudy conditions albeit at lower efficiency rates. Also advancements in panel design have made them more resistant against weather-related issues ensuring sustained performance even under heavy rainfall conditions.
