Windsor, California, located in the Northern Temperate Zone, offers a promising location for solar PV energy generation. The town experiences varying levels of solar potential throughout the year, with distinct seasonal patterns influencing electricity output.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy production in Windsor, with an impressive 8.34 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 7.39 kWh/day. These seasons provide ideal conditions for maximizing solar energy output.

Autumn sees a significant decrease in production, with 4.48 kWh/day, while winter experiences the lowest output at 2.85 kWh/day. Despite the reduced performance during colder months, Windsor's location still allows for year-round solar energy generation, albeit at varying levels of efficiency.

Optimal Panel Installation

For fixed panel installations in Windsor, the ideal tilt angle to maximize year-round solar production is 32 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While Windsor's climate is generally favorable for solar energy production, there are a few environmental factors to consider:

• Fog: The region can experience morning fog, particularly during summer months, which may temporarily reduce solar output.
• Wildfire smoke: California's wildfire season can lead to periods of reduced air quality and solar irradiance.

To mitigate these issues, regular panel cleaning and the use of high-quality, anti-soiling coatings can help maintain optimal performance. Additionally, installing a monitoring system can help identify and address any unexpected drops in production promptly.

Overall, Windsor's location provides a favorable environment for solar PV energy generation, with strong potential during spring and summer months and consistent, albeit reduced, output during autumn and winter.

Solar output per kW of installed solar PV by season in Windsor, California

Seasonal solar PV output for Latitude: 38.5463, Longitude: -122.8047 (Windsor, California, 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 32° South in Windsor, California, United States

To maximize your solar PV system's energy output in Windsor, California, United States (Lat/Long 38.5463, -122.8047) throughout the year, you should tilt your panels at an angle of 32° 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 Windsor, California, 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 Windsor, California, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
22° South in Summer	43° South in Autumn	53° South in Winter	31° 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 Windsor, California, 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 Windsor, California, 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 Windsor, California, United States

The topography around Windsor, California, located at latitude 38.5463 and longitude -122.8047, is characterized by a diverse and picturesque landscape. This region, situated in Sonoma County, is part of the larger Russian River Valley and is known for its rolling hills, gentle slopes, and fertile valleys. To the west of Windsor, the terrain gradually rises towards the coastal mountains, creating a series of undulating hills covered in a mix of grasslands, oak woodlands, and vineyards. These hills provide a natural barrier between the inland areas and the Pacific Ocean, which lies about 20 miles to the west. East of Windsor, the landscape becomes more level as it transitions into the Santa Rosa Plain. This relatively flat area extends southward towards Santa Rosa and is dotted with agricultural fields, including the region's famous vineyards. The plain is bordered to the east by the Mayacamas Mountains, which form a rugged backdrop to the valley. To the north and northeast of Windsor, the terrain becomes more varied, with a mix of gentle hills and small valleys. This area is home to numerous creeks and streams that feed into the Russian River, which flows southward through the region before turning west towards the Pacific Ocean.

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 ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The Santa Rosa Plain, east and southeast of Windsor, presents some of the most promising areas for solar PV development. This expansive, level terrain receives abundant sunlight and has fewer obstacles that could cast shadows on solar panels. Additionally, much of this area is already used for agriculture, which could potentially allow for dual-use solar installations that combine energy production with farming activities. Some of the gently sloping hillsides to the west and northwest of Windsor could also be suitable for solar PV installations, particularly those facing south or southwest. These areas benefit from excellent sun exposure throughout the day and could potentially utilize tracking systems to maximize energy production. However, it's important to note that any large-scale solar development in this region would need to carefully consider environmental impacts, agricultural preservation, and local zoning regulations. The area's reputation for wine production and natural beauty means that any solar projects would likely face scrutiny to ensure they align with the community's values and economic interests.
