Solar Energy Potential in Coos Bay, Oregon

Coos Bay, Oregon, located in the Northern Temperate Zone at coordinates 43.3692, -124.2203, presents a mixed picture for year-round solar energy generation via photovoltaic (PV) systems. The location experiences significant seasonal variations in solar energy production, which impacts its overall suitability for solar power.

Seasonal Solar Output

Summer stands out as the most productive season, with an impressive 6.76 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.83 kWh/day. These seasons offer excellent conditions for solar energy production, with long daylight hours and generally clearer skies. However, the picture changes dramatically during autumn and winter. Autumn sees a significant drop to 3.38 kWh/day, while winter plummets to a mere 1.71 kWh/day. This stark contrast highlights the challenges of maintaining consistent energy output throughout the year in Coos Bay.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Coos Bay, fixed solar panels should be installed at a tilt angle of 36 degrees facing south. This optimal angle helps capture the most sunlight across all seasons, balancing the high summer sun with the lower winter sun angle.

Environmental and Weather Considerations

Coos Bay's coastal location presents some challenges for solar energy production. The area is known for its frequent cloud cover and fog, especially during winter months. This can significantly reduce solar panel efficiency and overall energy output. Additionally, the region experiences high humidity and salt spray from the ocean, which can potentially damage solar equipment over time if not properly protected. To mitigate these issues, consider the following preventative measures:

• Use marine-grade materials and protective coatings on solar panels and mounting hardware to resist corrosion from salt spray.
• Implement regular cleaning schedules to remove salt deposits and other debris that may accumulate on panel surfaces.
• Consider micro-inverter or power optimizer technology to minimize the impact of partial shading from cloud cover.
• Install panels at a slightly steeper angle than the optimal 36 degrees to promote self-cleaning and reduce the accumulation of dirt and salt.

While Coos Bay may not be ideal for year-round solar energy production due to its climate, implementing these measures can help maximize the potential of solar PV systems in the area, particularly during the more favorable spring and summer months.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Coos Bay

Seasonal solar PV output for Latitude: 43.3692, Longitude: -124.2203 (Coos Bay, United States), 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 36° South in Coos Bay, United States

To maximize your solar PV system's energy output in Coos Bay, United States (Lat/Long 43.3692, -124.2203) 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 Coos Bay, 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 Coos Bay, 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	36° 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 Coos Bay, 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 Coos Bay, United States.

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 Coos Bay, United States

The topography around Coos Bay, Oregon, is characterized by a diverse and rugged landscape that reflects its coastal location and geological history. Situated along the Pacific Coast of the United States, Coos Bay is nestled within a region of rolling hills, coastal plains, and forested mountains. The immediate area surrounding Coos Bay features a mix of low-lying coastal plains and gently sloping hills. The bay itself is a large estuary formed where the Coos River meets the Pacific Ocean, creating a sheltered harbor surrounded by sandy beaches and rocky shorelines. Moving inland from the coast, the terrain gradually becomes more undulating, with forested hills rising to elevations of several hundred feet. To the east of Coos Bay, the landscape transitions into the Coast Range mountains. These mountains, while not exceptionally tall, are characterized by steep, forested slopes and deep valleys. The highest peaks in the vicinity reach elevations of around 2,000 to 3,000 feet above sea level. This mountainous terrain is dissected by numerous streams and rivers that flow westward towards the Pacific Ocean.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors must be taken into account. The coastal region around Coos Bay presents some challenges for solar energy due to its frequent cloud cover and limited flat terrain. However, there are potential areas that could be suitable for solar development: Inland valleys and plateaus east of Coos Bay offer more promising locations for solar PV installations. These areas, situated between the coastal hills and the Coast Range mountains, tend to have more consistent sunshine and larger expanses of relatively flat land. The region around the cities of Coquille and Myrtle Point, located about 20-30 miles southeast of Coos Bay, could potentially accommodate solar farms. Another area with potential for solar development is the coastal plain south of Coos Bay, extending towards Bandon. This area features some agricultural land and open spaces that could be repurposed for solar energy production. However, careful consideration would need to be given to environmental impacts and land-use regulations. It's important to note that while these areas may have better solar potential than the immediate vicinity of Coos Bay, they still face challenges such as seasonal variations in sunlight and the need for extensive environmental and feasibility studies. Any large-scale solar PV project in this region would require careful planning and collaboration with local communities and environmental agencies to ensure its viability and sustainability.
