Bandon, Oregon, in the United States, offers moderate potential for solar energy generation throughout the year. Located on the southern Oregon coast in the Northern Temperate Zone, this location experiences significant seasonal variations in solar productivity.
Seasonal Solar Performance
Solar panels in Bandon produce their highest output during summer months, generating approximately 6.76kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.83kWh/day per kW installed. Production drops considerably during autumn to 3.38kWh/day and reaches its lowest point in winter with only 1.71kWh/day.
This pattern creates a substantial difference between summer and winter production, with summer generating nearly four times the electricity of winter months. The combined spring and summer seasons (roughly April through September) represent the ideal period for solar generation in Bandon, when panels operate at their highest efficiency.
Optimal Installation Angle
For fixed solar panel installations in Bandon, the ideal tilt angle to maximize year-round energy production is 36 degrees facing South. This specific angle has been calculated to optimize annual solar collection based on Bandon's latitude of 43.119° North, accounting for seasonal sun paths and the Earth's elliptical orbit.
Environmental Challenges
Several significant environmental factors can impact solar production in Bandon:
- Coastal fog and marine layer intrusions are common, particularly during summer mornings, potentially reducing solar output during otherwise productive months
- The region receives substantial rainfall (approximately 65 inches annually), with most precipitation occurring during winter months when solar production is already at its lowest
- Strong coastal winds can carry salt spray, which may gradually degrade panel efficiency if not properly maintained
- Winter storms can bring extended periods of cloud cover, further diminishing the already low winter production values
Preventative Measures
To maximize solar production despite these challenges, consider implementing these measures:
- Install panels with anti-reflective coatings specifically designed for coastal environments
- Incorporate regular cleaning protocols to remove salt deposits and debris
- Consider slightly west-facing orientation (5-10° west of south) to capture more afternoon sun when morning fog has typically cleared
- Use microinverters or power optimizers to minimize the impact of partial shading from fog or clouds
- Install panels at a slightly steeper angle than the recommended 36° during winter months if seasonal adjustments are possible
While Bandon's solar potential is moderate compared to sunnier regions, proper system design accounting for these local conditions can still result in worthwhile energy generation, particularly during the productive spring and summer months.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 36° South in Bandon, United States
To maximize your solar PV system's energy output in Bandon, United States (Lat/Long 43.119, -124.4085) throughout the year, you should tilt your panels at an angle of 36° 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 Bandon, United States
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 Bandon, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 46° South in Autumn | 57° South in Winter | 35° 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 Bandon, United States
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 Bandon, United States.
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 Bandon, United States
Bandon, Oregon, nestled along the southern Oregon coast, features a diverse and dynamic topography that shapes its landscape. The terrain around Bandon primarily consists of coastal plains, rolling hills, and rugged headlands where the land meets the Pacific Ocean. The Coquille River winds through the area, creating a natural harbor and estuary system before emptying into the ocean. East of the immediate coastline, the landscape transitions to more pronounced hills that gradually rise toward the Coast Range mountains further inland. The coastal section of Bandon is characterized by dramatic sea stacks, expansive beaches, and coastal bluffs. These iconic rock formations just offshore are remnants of the coastline's ongoing erosion by the powerful Pacific waves. Moving inland, the terrain becomes more varied with a mix of open meadows, agricultural lands, and forested areas dominated by coastal pine, spruce, and deciduous trees.
Solar PV Potential Areas
For large-scale solar photovoltaic (PV) installations near Bandon, several areas present more favorable conditions than others. The inland valleys and gently sloping hillsides east of Bandon offer the most promising locations for solar development. These areas typically experience less coastal fog and cloud cover compared to the immediate shoreline, allowing for greater solar exposure. The agricultural lands that extend along the Coquille River valley, particularly those with south-facing slopes, would be most suitable for solar PV installations. These locations benefit from clearer skies and more consistent sunshine than the immediate coastal zone, which frequently experiences marine layer fog and cloud cover that can significantly reduce solar efficiency. The slightly elevated plateaus found 5-10 miles inland from Bandon also present good opportunities for solar development. These areas sit above the heaviest coastal fog influence while still having relatively flat terrain that simplifies construction and panel placement. The rolling hills southeast of Bandon, extending toward the communities of Langlois and Sixes, offer several potential sites where the land is already cleared and has favorable solar aspect. It's worth noting that while the Coast Range mountains further east have slopes with excellent southern exposure, the increased forest cover and more rugged terrain would require significant clearing and grading, making these areas less economically viable for large-scale solar development despite potentially good solar resources. Any solar development would need to consider the region's seasonal weather patterns, as winter months bring increased precipitation and cloud cover throughout the area. The most optimal solar PV locations would be those inland areas with good drainage, minimal shading from surrounding hills or forests, and proximity to existing electrical infrastructure for grid connection.United States solar PV Stats as a country
