Solar Energy Potential in Angol, Región de la Araucanía, Chile
Angol, Región de la Araucanía, Chile, located in the Southern Temperate Zone at latitude -37.7995 and longitude -72.7169, presents a variable environment for solar energy generation throughout the year. This location experiences significant seasonal fluctuations in solar energy production that prospective solar panel users should consider. The energy output from solar PV installations in Angol follows a predictable seasonal pattern. During summer months, production reaches its peak at an impressive 8.75 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.75 kWh/day. Production decreases considerably during autumn to 4.29 kWh/day, while winter represents the annual low point with just 2.51 kWh/day per kilowatt installed.Seasonal Variations and Installation Considerations
For residents of Angol considering solar installations, it's important to note that for fixed panel installations, the ideal tilt angle to maximize year-round energy production is 32 degrees facing North. This specific angle has been calculated by analyzing the optimal panel positions throughout the year, weighted by the potential daily production at this latitude. The substantial difference between summer and winter production (nearly 3.5 times more energy in summer) indicates that Angol is not ideal for year-round consistent solar generation. However, the location still offers excellent potential during spring and summer months, which could provide sufficient energy to offset a significant portion of annual electricity needs.Environmental and Weather Factors
Several environmental factors in Angol may affect solar energy production. The region experiences a Mediterranean climate with rainy winters, which contributes to the lower winter production values. Cloud cover during the rainy season can significantly reduce solar irradiance reaching panels. Additionally, Angol's location near the Nahuelbuta mountain range can create localized weather patterns including morning fog in some seasons. The region is also subject to occasional volcanic ash from distant volcanoes in the Andes, which can temporarily decrease panel efficiency.Preventative Measures for Optimal Production
To maximize solar energy production in Angol, Región de la Araucanía, several preventative measures can be implemented:- Install self-cleaning panel systems or implement regular cleaning schedules, particularly during dry summer months when dust accumulation is highest
- Use microinverters or power optimizers to minimize the impact of partial shading from nearby trees or structures
- Consider slightly adjustable mounting systems to optimize tilt seasonally (steeper in winter, flatter in summer)
- Implement robust mounting structures that can withstand occasional strong winds from the coastal influence
- Select panels with good low-light performance to improve energy harvest during cloudy winter days
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° latitude.

Ideally tilt fixed solar panels 32° North in Angol, Chile
To maximize your solar PV system's energy output in Angol, Chile (Lat/Long -37.7995, -72.7169) throughout the year, you should tilt your panels at an angle of 32° 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 Angol, Chile
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 Angol, Chile. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° North in Summer | 42° North in Autumn | 53° North in Winter | 30° 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 Angol, Chile
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 Angol, Chile.
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 Angol, Chile
Topography Around Angol, Chile
Angol is situated in the Malleco Province of Chile's Araucanía Region, nestled in a transitional zone between the fertile Central Valley and the majestic Nahuelbuta mountain range. The topography around Angol is characterized by a diverse landscape that includes rolling hills, river valleys, and mountainous terrain to the west. The city itself sits at an elevation of approximately 80-100 meters above sea level in a relatively flat valley. As one moves eastward from Angol, the land gradually rises toward the foothills of the Andes Mountains, creating a gentle ascending gradient. This eastern region features undulating hills and plateaus that gradually increase in elevation. To the west of Angol lies the Nahuelbuta mountain range, a coastal mountain system that runs parallel to the Pacific Ocean. These mountains rise quite dramatically, reaching heights of over 1,500 meters, creating a significant topographical barrier between the central valley where Angol is located and the Pacific coast. The Nahuelbuta range is densely forested, primarily with native Araucaria trees, creating a lush, green landscape. The area is also marked by several river systems, most notably the Vergara River which flows through Angol itself. These waterways have carved valleys throughout the region, creating natural corridors through the otherwise varied terrain. The river valleys tend to be fertile and flat, contrasting with the surrounding elevated areas.Optimal Areas for Solar PV Development
When considering large-scale solar photovoltaic development around Angol, several areas present favorable conditions based on topographical considerations alone. The eastern plains and gentle hills extending from Angol toward the Andes foothills offer perhaps the most promising terrain for large-scale solar installations. These areas benefit from relatively flat or gently sloping land that would require minimal grading and preparation for solar array installation. The gradual east-facing slopes in this region would be particularly advantageous for capturing morning and midday sunlight. The central valley areas north and south of Angol also present suitable topography for solar development. These flat expanses would allow for efficient layout of solar arrays with minimal topographical complications. The open nature of the valley provides good exposure to sunlight throughout the day with limited shadowing from geographical features. The elevated plateaus found in the transitional zones between the valley and mountain ranges offer another potential option. While these areas might require more site preparation due to their variable terrain, they often benefit from reduced fog exposure compared to lower valley locations, potentially increasing solar efficiency. Areas to avoid would include the western slopes of the Nahuelbuta range, which not only present challenging construction conditions due to steep gradients but may also experience more cloud cover due to orographic effects as Pacific moisture rises over the mountains. Similarly, the densely forested sections of the Nahuelbuta mountains would require extensive clearing, creating both environmental concerns and additional development costs. River valleys, while flat and accessible, may be better preserved for agricultural use given their fertility, and some may be subject to seasonal flooding concerns that could complicate solar infrastructure development. The ideal solar PV locations would balance accessibility, minimal slope, good drainage, and distance from environmentally sensitive areas while maintaining proximity to existing transmission infrastructure to facilitate grid connection.Chile solar PV Stats as a country
Chile ranks 22nd in the world for cumulative solar PV capacity, with 4,468 total MW's of solar PV installed.
