Solar output per kW of installed solar PV by season in Motul

Seasonal solar PV output for Latitude: 21.1418, Longitude: -89.2817 (Motul, Mexico), 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 19° South in Motul, Mexico

To maximize your solar PV system's energy output in Motul, Mexico (Lat/Long 21.1418, -89.2817) throughout the year, you should tilt your panels at an angle of 19° 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 Motul, Mexico

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 Motul, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° South in Summer	26° South in Autumn	36° South in Winter	15° 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 Motul, Mexico

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 Motul, Mexico.

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 Motul, Mexico

The topography around Motul, Mexico, located at latitude 21.1418 and longitude -89.2817, is characterized by a predominantly flat landscape typical of the Yucatán Peninsula. This region is known for its low-lying terrain with minimal elevation changes, creating a vast expanse of level ground that stretches for miles in all directions. The area surrounding Motul is part of a larger geological formation called the Yucatán Platform, which is composed primarily of limestone bedrock. This limestone foundation has been shaped over millions of years by the gradual erosion and dissolution of the rock, resulting in a karst topography. While the surface appears flat, beneath lies a complex network of underground caves, cenotes (natural sinkholes filled with groundwater), and subterranean rivers. Vegetation in the region consists mainly of tropical dry forests and scrublands, with patches of more lush growth near water sources. The flat terrain and relatively sparse tree cover contribute to the area's potential for solar energy development.

Suitability for Large-Scale Solar PV

When considering areas nearby Motul for large-scale solar photovoltaic (PV) installations, several factors make this region particularly attractive. The flat topography eliminates the need for extensive land preparation, reducing construction costs and environmental impact. Additionally, the area experiences high levels of solar radiation throughout the year, thanks to its tropical latitude and generally clear skies. The most suitable locations for solar PV development would be found in the open areas surrounding Motul, particularly to the north and east where there are fewer settlements and more expansive tracts of undeveloped land. These areas offer the advantage of minimal shading from natural features or man-made structures, maximizing solar exposure throughout the day. However, it's important to note that while the topography is favorable, other factors must be considered when selecting specific sites for solar installations. These include proximity to existing electrical infrastructure, access to roads for construction and maintenance, and the need to avoid ecologically sensitive areas such as cenotes or protected habitats. The region's limestone bedrock may present some challenges for anchoring solar panel arrays, but modern engineering solutions can address these issues. Additionally, the risk of hurricanes and tropical storms in this coastal area would necessitate robust design and construction practices to ensure the longevity and resilience of any large-scale solar PV projects. Overall, the flat, open landscape around Motul provides excellent potential for solar energy development, offering ample space and ideal conditions for capturing the abundant sunlight that bathes this part of the Yucatán Peninsula.
