Solar PV Analysis of Nassau, Bahamas
Nassau, New Providence District, Bahamas is a highly suitable location for solar photovoltaic (PV) generation. The average energy production per day for each kilowatt of installed solar capacity in this city (latitude: 25.0582, longitude: -77.3431) varies by season: 6.94 kWh in Summer, 5.08 kWh in Autumn, 4.60 kWh in Winter, and 7.11 kWh in Spring.
The high energy production during the Summer and Spring seasons can be attributed to longer daylight hours and more direct sunlight exposure at this location. However, certain local factors such as heavy rainfall or strong winds may occasionally impact solar power output.
To mitigate these potential challenges, it is advisable to install solar panels with a fixed tilt angle of 22 degrees facing southward to optimize energy generation throughout the year. Additionally, ensuring proper installation and regular maintenance of the solar PV system will help maintain its efficiency and reduce any potential losses due to environmental factors.
In summary, Nassau's favorable geographic position along with careful planning during installation can result in consistent and efficient solar power generation throughout the year despite occasional weather-related challenges that may arise at this location
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 5 locations across Bahamas. 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 Nassau
Seasonal solar PV output for Latitude: 25.0582, Longitude: -77.3431 (Nassau, Bahamas), 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 22° South in Nassau, Bahamas
To maximize your solar PV system's energy output in Nassau, Bahamas (Lat/Long 25.0582, -77.3431) throughout the year, you should tilt your panels at an angle of 22° 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 Nassau, Bahamas
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 Nassau, Bahamas. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 30° South in Autumn | 40° South in Winter | 18° 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 Nassau, Bahamas
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 Nassau, Bahamas.
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 Nassau, Bahamas
The topography around Nassau, Bahamas is generally flat. Areas near the coast are low-lying and there are some small hills in the interior of the island. The most suitable areas for large-scale solar PV would be open spaces with good sun exposure, such as rooftops or open fields. Areas close to the coast that receive direct sunlight for most of the day would also be ideal for solar PV installations.
