Portmore, Saint Catherine Parish, Jamaica is a very good location for generating energy through solar PV panels all year round. This is because it's located in the tropics where sunlight is consistent throughout most of the year. The seasons here are more about wet and dry periods rather than drastic changes in temperature or sunlight.

The amount of electricity that can be generated from each kW of installed solar varies slightly by season:

- In summer, you can expect to generate around 6.75 kWh per day per kW.
- In autumn, this drops a little to about 5.97 kWh per day per kW.
- Winter sees a further drop to approximately 5.36 kWh per day per kW.
- Springtime brings the highest output at around 7.05 kWh per day per kW.

So while there are some fluctuations across seasons, overall this location provides ample sunshine for effective solar energy generation throughout the year.

For fixed panel installations at this location, tilting your panels at an angle of 16 degrees South will maximise your total yearly production from solar PV systems.

However, local environmental and weather factors could potentially affect solar production at this location:

1) As Portmore experiences both wet and dry seasons, heavy rainfall during wet periods might reduce sunlight exposure temporarily which could impede on electricity generation.

2) High winds or storms could potentially damage panels if they're not properly secured and protected.

To mitigate these issues:

1) Regular cleaning and maintenance should be performed especially after heavy rainfalls to ensure maximum efficiency of the panels

2) Panels should be securely mounted with wind-resistant materials and design considerations to withstand high winds or storms

In conclusion, Portmore's consistent tropical sun makes it an excellent place for generating solar power all year round with just minor seasonal variations in output levels - making it ideal for harnessing renewable energy via photovoltaic systems!

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 Portmore

Seasonal solar PV output for Latitude: 17.9686, Longitude: -76.8827 (Portmore, 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:

Average 6.75kWh/day in Summer.

Average 5.97kWh/day in Autumn.

Average 5.36kWh/day in Winter.

Average 7.05kWh/day in Spring.

Ideally tilt fixed solar panels 16° South in Portmore, Jamaica

To maximize your solar PV system's energy output in Portmore, Jamaica (Lat/Long 17.9686, -76.8827) 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.

At Latitude: 17.9686, Longitude: -76.8827, the ideal angle to tilt panels is 16° South

Seasonally adjusted solar panel tilt angles for Portmore, 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 Portmore, Jamaica. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° 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 Portmore, 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 Portmore, Jamaica.

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 Portmore, Jamaica

Portmore, Jamaica is a coastal city located on the flat plains of the Liguanea formation. This area consists mostly of alluvial flatlands and wetlands with some low-lying hills, making it quite suitable for solar PV installations.

The topography around Portmore is largely flat which is ideal for large-scale solar PV installations as it allows for easy installation and maintenance while maximizing exposure to sunlight. The climate in this region also supports solar energy production as it receives abundant sunlight throughout the year.

Areas most suited for large scale solar PV would be open, unobstructed spaces such as agricultural lands or unused industrial areas that are not prone to flooding. Additionally, rooftops of commercial or residential buildings could also be used effectively for smaller scale installations within the city itself.

However, a comprehensive feasibility study should be conducted before deciding on specific locations. This study should consider factors like land availability and use restrictions, proximity to power grids or end users (to minimize transmission losses), environmental impact assessments etc., apart from just topographical suitability.
