Solar PV Analysis of La Conner, United States
La Conner, Washington, located in the Northern Temperate Zone, presents a mixed scenario for year-round solar energy generation via photovoltaic (PV) systems. The location's seasonal variations in solar output highlight both opportunities and challenges for solar power production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 7.15 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 5.30 kWh/day. These warmer months offer ideal conditions for solar energy production, with longer daylight hours and typically clearer skies.
However, the colder months show a significant drop in solar output. Autumn produces 2.42 kWh/day, while winter sees the lowest generation at just 1.34 kWh/day. This stark contrast between seasons underscores the importance of efficient system design and energy management strategies to balance year-round energy needs.
Optimizing Solar Panel Installation
To maximize year-round solar production at this location, fixed solar panels should be tilted at a 40-degree angle facing south. This optimal angle helps capture the most sunlight throughout the year, considering La Conner's latitude and the sun's changing position across seasons.
Environmental and Weather Considerations
La Conner's climate presents some challenges for solar energy production. The area experiences significant rainfall, particularly during the fall and winter months, which can reduce solar efficiency. Additionally, the region is known for its cloudy days, especially in the cooler seasons, further impacting solar generation.
To mitigate these environmental factors, several preventative measures can be taken:
- Use high-efficiency panels designed to perform well in low-light conditions
- Install a robust mounting system to withstand potential wind and rain
- Implement regular cleaning and maintenance to remove debris and ensure optimal performance
Despite these challenges, La Conner's location still offers substantial potential for solar energy production, particularly during the spring and summer months. With proper system design and maintenance, solar PV can be a viable renewable energy option for this Washington community.
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 La Conner
Seasonal solar PV output for Latitude: 48.4093, Longitude: -122.5313 (La Conner, 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 40° South in La Conner, United States
To maximize your solar PV system's energy output in La Conner, United States (Lat/Long 48.4093, -122.5313) throughout the year, you should tilt your panels at an angle of 40° 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 La Conner, 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 La Conner, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 32° South in Summer | 51° South in Autumn | 62° South in Winter | 40° 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 La Conner, 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 La Conner, 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 La Conner, United States
The topography around La Conner, Washington, is characterized by a mix of low-lying coastal plains and gently rolling hills. La Conner itself is situated in the Skagit Valley, a fertile agricultural region known for its rich soil and flat terrain. The town sits near sea level, with an elevation of only about 20 feet above sea level.
To the west of La Conner, you'll find the Swinomish Channel, which separates the mainland from Fidalgo Island. This area is predominantly flat, with some marshlands and tidal flats. As you move eastward from La Conner, the landscape gradually transitions into more undulating terrain, with small hills and valleys becoming more prominent.
The Skagit River, which flows to the south of La Conner, has played a significant role in shaping the local topography. Over thousands of years, it has deposited sediment and created the expansive floodplain that makes up much of the valley floor. This flat, open terrain extends for several miles in all directions around La Conner.
Further east, the landscape becomes more dramatic as it approaches the foothills of the Cascade Mountains. However, this mountainous region is still quite distant from La Conner itself, with the closest significant elevations being about 20-30 miles away.
Regarding areas nearby that would be most suited to large-scale solar PV installations, the flat, open farmlands of the Skagit Valley present the most promising opportunities. These areas offer several advantages for solar energy development:
- Large, unobstructed spaces that receive ample sunlight throughout the day
- Relatively low land costs compared to more developed urban areas
- Easy access for construction and maintenance vehicles
- Proximity to existing power infrastructure
However, it's important to note that the Skagit Valley is known for its valuable agricultural land, which may create conflicts between solar development and farming interests. Additionally, the region's climate, characterized by frequent cloud cover and rain, especially in the winter months, may pose challenges for solar energy production efficiency.
Areas slightly east of La Conner, where the terrain begins to rise and become more varied, might offer a good compromise. These locations could potentially provide elevated sites with good sun exposure while avoiding the most productive agricultural lands. However, any large-scale solar development would need to carefully consider environmental impacts, local zoning regulations, and community concerns.
