Camas, Washington, located in the United States, presents a mixed profile for solar energy generation via photovoltaic (PV) systems. Situated in the Northern Temperate Zone at coordinates 45.5871, -122.3995, this location experiences significant seasonal variations in solar energy production.

Seasonal Solar Performance

Solar energy output in Camas fluctuates considerably throughout the year. Summer stands out as the most productive season, with an impressive 7.12 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.46 kWh/day. However, autumn and winter see a substantial drop in production, with 2.90 kWh/day and 1.36 kWh/day respectively.

Optimal Times for Solar Generation

The most ideal period for solar energy production in Camas spans from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. Conversely, the winter months, particularly December and January, are the least productive due to shorter days and lower sun angles.

Panel Installation Considerations

For fixed panel installations in Camas, the optimal tilt angle to maximize year-round solar production is 38 degrees facing south. This angle is calculated based on the location's latitude and accounts for the Earth's elliptical orbit, ensuring the best possible exposure to sunlight throughout the year.

Environmental and Weather Factors

Several environmental factors can impact solar production in Camas:

1. Cloud cover: The Pacific Northwest is known for its cloudy weather, particularly in fall and winter, which can significantly reduce solar output.
2. Rain: Frequent rainfall, especially during the cooler months, can further diminish solar efficiency.
3. Snow: While not as common as rain, occasional snowfall can temporarily cover panels, reducing their effectiveness.

Preventative Measures

To mitigate these challenges and enhance solar energy production, consider the following measures:

• Install panels at the optimal 38-degree angle to maximize exposure and encourage snow or water runoff.
• Use high-efficiency panels designed to perform well in low-light conditions.
• Implement a regular cleaning schedule to remove debris and ensure optimal panel performance.
• Consider a tracking system to follow the sun's path, potentially increasing energy production by 25-35%.

While Camas may not be ideal for year-round solar energy production due to its seasonal variations and weather patterns, proper installation techniques and maintenance can still make solar PV systems a viable and beneficial energy option for this location.

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

Ideally tilt fixed solar panels 38° South in Camas, United States

To maximize your solar PV system's energy output in Camas, United States (Lat/Long 45.5871, -122.3995) throughout the year, you should tilt your panels at an angle of 38° 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 Camas, 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 Camas, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
29° South in Summer	48° South in Autumn	60° South in Winter	38° 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 Camas, 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 Camas, 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 Camas, United States

The topography around Camas, Washington, United States, is characterized by a diverse landscape that transitions from the Columbia River floodplain to the foothills of the Cascade Mountains. Situated on the north bank of the Columbia River, Camas is nestled in a region of rolling hills, plateaus, and river valleys. To the south of Camas, the Columbia River forms a wide, flat valley with rich alluvial soil. This area is relatively low-lying and prone to flooding during periods of high water. As you move north and east from the river, the land begins to rise gradually, forming a series of terraces and hills. The city itself is built on a gently sloping plain that rises from the river's edge. As you move further north, the terrain becomes more varied, with steeper hills and deeper valleys. The landscape is dotted with small streams and creeks that flow southward towards the Columbia River.

Potential Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have relatively flat or gently sloping terrain, good sun exposure, and minimal shading from surrounding hills or vegetation. The areas to the east and northeast of Camas, extending towards the town of Washougal and beyond, offer promising potential for solar PV development. This region features expansive plateaus and open farmland with fewer trees and obstructions. The gently rolling terrain in this area provides ample space for large arrays of solar panels while minimizing the need for extensive land grading. Another potentially suitable area lies to the north of Camas, in the vicinity of Lacamas Lake and extending towards the community of Fern Prairie. This region has some flatter areas interspersed with low hills, which could accommodate solar installations while taking advantage of south-facing slopes for optimal sun exposure. It's important to note that while these areas may be topographically suitable for solar PV, other factors such as land ownership, zoning regulations, and environmental considerations would need to be carefully evaluated before any large-scale solar projects could be implemented. Additionally, the region's climate, characterized by frequent cloud cover and rain, particularly in the winter months, may impact the overall efficiency and viability of solar energy production in this area.
