Rada Tilly, Chubut, Argentina, situated in the Southern Temperate Zone, offers varying potential for solar energy generation throughout the year. This coastal Patagonian town experiences significant seasonal fluctuations in solar electricity production that potential solar adopters should understand.
Seasonal Solar Production
Solar panels in Rada Tilly would produce their maximum output during summer months, generating an impressive 8.29kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.17kWh/day per installed kilowatt. Production drops considerably during autumn to 3.28kWh/day, while winter sees the lowest generation at just 1.89kWh/day per kilowatt installed.
This pattern creates a more than four-fold difference between the best and worst seasons, making Rada Tilly a location with pronounced seasonal solar generation characteristics. The summer-spring period (approximately October through March) would provide substantially more solar electricity than the autumn-winter months.
Optimal Panel Installation
For fixed solar panel installations in Rada Tilly, Chubut, the ideal tilt angle to maximize year-round production is 39 degrees facing North. This angle has been calculated by analyzing daily solar elevation patterns at this specific latitude, weighted by the potential daily production throughout the year.
Environmental and Weather Considerations
Several factors could potentially impact solar production in Rada Tilly:
- Strong Patagonian winds can deposit dust and sand on panels, reducing efficiency if not regularly cleaned
- Coastal salt spray may accelerate corrosion of mounting hardware and electrical connections
- Winter snowfall, though infrequent, could temporarily cover panels
- Seasonal fog from the nearby Atlantic Ocean may reduce solar irradiance during certain periods
Preventative Measures
To maximize production despite these challenges, solar installations in Rada Tilly should incorporate:
- Robust mounting systems designed to withstand Patagonian wind conditions
- Marine-grade components with enhanced corrosion resistance
- Regular cleaning schedule, especially after dust storms
- Slight increase in tilt angle (beyond the optimal 39°) if winter production is prioritized, to facilitate snow shedding
- High-quality inverters that perform efficiently even during lower irradiance conditions
Given the significant seasonal variation, homeowners might consider coupling solar PV with energy storage solutions to better utilize the abundant summer production throughout the year. Alternatively, a hybrid renewable system incorporating wind energy could provide more consistent year-round generation in this windy coastal region.

Solar output per kW of installed solar PV by season in Rada Tilly
Seasonal solar PV output for Latitude: -45.9333, Longitude: -67.5333 (Rada Tilly, Argentina), 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 39° North in Rada Tilly, Argentina
To maximize your solar PV system's energy output in Rada Tilly, Argentina (Lat/Long -45.9333, -67.5333) throughout the year, you should tilt your panels at an angle of 39° North 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 Rada Tilly, Argentina
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 Rada Tilly, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° North in Summer | 50° North in Autumn | 60° North in Winter | 38° North 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 Rada Tilly, Argentina
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 Rada Tilly, Argentina.
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 Rada Tilly, Argentina
The region surrounding Rada Tilly, Argentina presents a diverse topographical landscape characteristic of Patagonia's eastern coast. Situated along the Atlantic Ocean in Chubut Province, Rada Tilly is nestled in a natural bay, with the terrain rising gradually from sea level into a series of plateaus and hills moving inland.
Coastal Features
Rada Tilly sits on a small coastal plain bordered by the Golfo San Jorge to the east. This coastal area features sandy beaches along a sheltered bay, which transitions to low cliffs in some sections. The shoreline is relatively flat, with the elevation increasing gently as one moves westward away from the ocean.Inland Topography
Moving inland from the coast, the landscape transforms into a series of arid steppes and plateaus typical of the Patagonian region. These plateaus, known locally as "mesetas," are characterized by their flat tops and steep sides, often cut by seasonal water courses that have eroded valleys through the otherwise level terrain. The elevation generally increases from east to west, with the plateaus reaching heights of several hundred meters above sea level. The terrain features sparse vegetation adapted to the arid conditions, primarily consisting of low shrubs and hardy grasses. This vegetation pattern reflects the region's semi-desert climate, with limited rainfall throughout the year.Regional Relief
The broader region exhibits a varied relief pattern. To the north and west of Rada Tilly, the landscape becomes more irregular, with hills and depressions forming a patchwork of different elevations. The terrain is marked by erosional features, including dry ravines (cañadones) that cut through the plateaus, creating a network of shallow valleys. Wind erosion has played a significant role in shaping the landscape, with prevailing westerly winds continually modifying the surface features. This has resulted in some areas displaying wind-sculpted rock formations and sand accumulations.Optimal Areas for Solar PV Development
For large-scale solar photovoltaic installations, the inland plateaus west of Rada Tilly offer particularly favorable conditions. These elevated flat areas present several advantages: The extensive mesetas provide large, continuous tracts of relatively level land, reducing the need for significant terrain modification during installation. Their elevated position minimizes shadowing effects that might otherwise reduce solar panel efficiency. Areas approximately 10-30 kilometers inland from Rada Tilly strike an optimal balance between accessibility and favorable topographical conditions. These locations are sufficiently removed from the immediate coastal zone (where salt spray and humidity levels are higher) yet remain accessible via existing transportation infrastructure. The northern-facing gentle slopes of the plateaus would be particularly well-suited for solar arrays, as they receive consistent solar exposure throughout the day. The sparse vegetation and minimal agricultural use of these arid lands mean that development would have relatively low impact on existing land use patterns. The plateaus south and southwest of the nearby city of Comodoro Rivadavia (which is just north of Rada Tilly) also present excellent conditions for solar development, with extensive flat areas that experience minimal cloud cover throughout the year. The combination of elevation, flat terrain, and limited competing land uses makes these inland plateau regions the most promising areas for large-scale solar PV development in the vicinity of Rada Tilly.Argentina solar PV Stats as a country
