Solar PV Analysis of Spanish Town, Jamaica
Spanish Town, Saint Catherine Parish, Jamaica is a rather good location for generating solar energy year-round due to its tropical climate with consistent sunlight throughout most of the year. The amount of electricity that can be produced from each kilowatt (kW) of installed solar panels varies by season, but remains relatively high all year. In summer and spring, you can expect to generate around 6.75 and 7.05 kilowatt-hours (kWh) per day respectively from each kW of installed solar panels. During autumn and winter, this drops slightly to about 5.97 and 5.36 kWh/day respectively.
The best times of the year for producing solar energy at this location are during the spring and summer seasons when sunlight is most abundant. To maximize your total annual production from your solar photovoltaic (PV) system in Spanish Town, Saint Catherine Parish, it would be ideal to tilt your panels at an angle of 16 degrees facing south.
However, there might be some local factors that could potentially affect your solar energy production in Spanish Town - these include environmental or weather conditions such as heavy rainfall or hurricanes which are common in tropical regions like Jamaica. These extreme weather conditions may not only reduce the amount of sunlight reaching your panels but could also damage them.
To safeguard against these potential challenges, you should consider installing durable PV systems designed to withstand harsh weather conditions along with proper anchoring systems to prevent wind damage during hurricane season.
Additionally, regular maintenance checks should be conducted especially after heavy rainfalls or storms; ensuring that there's no debris blocking sunlight from reaching the panels will help maintain optimum performance levels for greater energy production.
In summary: With its ample sunshine throughout much of the year coupled with taking preventative measures against adverse weather events common in tropics like hurricanes - Spanish Town appears quite suitable for generating substantial amounts of renewable energy via Solar PV installations all-year-round!
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 19 locations across Jamaica. 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 Spanish Town
Seasonal solar PV output for Latitude: 17.9869, Longitude: -76.9499 (Spanish Town, Jamaica), 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 16° South in Spanish Town, Jamaica
To maximize your solar PV system's energy output in Spanish Town, Jamaica (Lat/Long 17.9869, -76.9499) throughout the year, you should tilt your panels at an angle of 16° 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 Spanish Town, Jamaica
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 Spanish Town, Jamaica. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° South in Summer | 23° South in Autumn | 33° South in Winter | 11° 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 Spanish Town, Jamaica
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 Spanish Town, Jamaica.
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 Spanish Town, Jamaica
Spanish Town, Jamaica is located in the southeastern part of the country. The topography around Spanish Town is quite diverse with a mix of flat coastal plains and hilly terrains. To its south lies the Kingston Harbour and to its north are mountainous regions.
The areas most suited for large-scale solar PV installations would be those that have plenty of sunlight throughout the year, relatively flat terrain for easy installation, and minimal shading from trees or buildings. Given these considerations, the coastal plains surrounding Spanish Town could be potential sites for large-scale solar PV projects due to their relatively flat terrain and abundant sunlight.
However, it's also important to consider other factors such as land use (whether it's agricultural land or protected natural areas), proximity to power grids for electricity transmission, local regulations on renewable energy projects among others before deciding on a location. A detailed site assessment would therefore be necessary to identify suitable locations around Spanish Town for large scale solar PV installations.
