Carmel, California, situated at latitude 36.5428 and longitude -121.8948, offers a promising location for solar energy production throughout the year. This coastal town in the Northern Temperate Zone experiences varying levels of solar potential across different seasons, making it an interesting case study for solar PV installations.

Seasonal Solar Performance

Solar energy generation in Carmel follows a predictable pattern, with peak production occurring during the summer months. The average daily electricity output per kilowatt of installed solar capacity ranges from a high of 8.08 kWh in summer to a low of 3.23 kWh in winter. Spring and autumn fall between these extremes, with 7.31 kWh and 4.94 kWh per day, respectively.

The most ideal time for solar energy production in Carmel is from late spring through early fall. During this period, longer days and clearer skies contribute to optimal solar panel performance. However, even during the less productive winter months, the panels continue to generate a significant amount of electricity, making year-round solar energy production viable in this location.

Optimal Panel Tilt

For fixed solar panel installations in Carmel, the ideal tilt angle to maximize year-round energy production is 31 degrees facing south. This angle takes into account the location's latitude and the sun's position throughout the year, ensuring the panels capture the maximum amount of sunlight possible across all seasons.

Environmental Considerations

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

1. Coastal fog: Carmel's proximity to the Pacific Ocean can lead to frequent morning fog, potentially reducing solar output during early hours.
2. Marine layer: The marine layer common to coastal California can sometimes persist throughout the day, slightly diminishing solar energy production.

To mitigate these factors, solar installers can consider using high-efficiency panels that perform well in diffuse light conditions. Additionally, incorporating a solar tracking system could help maximize energy capture by following the sun's path throughout the day, compensating for any periods of reduced direct sunlight.

Despite these minor challenges, Carmel remains an excellent location for solar PV installations. The combination of mild temperatures, generally clear skies, and consistent solar radiation throughout the year makes it a prime spot for harnessing solar energy effectively.

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 Carmel, California

Seasonal solar PV output for Latitude: 36.5428, Longitude: -121.8948 (Carmel, 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 31° South in Carmel, California, United States

To maximize your solar PV system's energy output in Carmel, California, United States (Lat/Long 36.5428, -121.8948) throughout the year, you should tilt your panels at an angle of 31° 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 Carmel, 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 Carmel, California, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
20° South in Summer	41° South in Autumn	51° South in Winter	29° 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 Carmel, 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 Carmel, 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 Carmel, California, United States

The topography around Carmel, California, is characterized by a diverse and picturesque landscape that combines coastal features with inland hills and mountains. Situated along the central California coast, Carmel is nestled between the Pacific Ocean to the west and the Santa Lucia Mountains to the east. The immediate coastal area features sandy beaches and rocky cliffs that dramatically meet the ocean. As you move inland from the coast, the terrain gradually rises into rolling hills covered with a mix of grasslands, chaparral, and forests. These hills become steeper and more rugged as they transition into the Santa Lucia Mountains, which form part of the Coast Ranges.

Coastal Plains and Valleys

Just north of Carmel, the Carmel Valley stretches inland, offering a relatively flat area surrounded by hills. This valley, formed by the Carmel River, provides some of the more level terrain in the region. To the south, the Big Sur coastline begins, known for its steep cliffs and winding roads that hug the mountainsides as they drop to the sea.

Mountain Ranges

The Santa Lucia Mountains dominate the eastern landscape, with peaks reaching heights of over 5,000 feet. These mountains are part of the Los Padres National Forest and feature deep canyons, steep ridges, and diverse ecosystems ranging from coastal redwood forests to drier chaparral-covered slopes.

Potential for Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would offer relatively flat terrain, good sun exposure, and minimal environmental impact. The Salinas Valley, located to the east of the Santa Lucia Mountains, presents the most promising area for large-scale solar PV development. This vast agricultural region, often called the "Salad Bowl of the World," features extensive flat lands that receive ample sunlight throughout the year. The valley's orientation and lack of significant shading from mountains make it an excellent candidate for solar energy production. Areas around King City and Greenfield, situated in the southern part of the Salinas Valley, could be particularly suitable. These locations offer the advantage of being somewhat removed from the most productive agricultural lands while still providing the necessary topographical and climatic conditions for efficient solar energy generation. It's important to note that while the Salinas Valley offers the best potential for large-scale solar PV near Carmel, any development would need to carefully consider agricultural land use, water resources, and potential environmental impacts. The immediate vicinity of Carmel itself, with its hilly terrain and emphasis on preserving natural beauty, is less suitable for large-scale solar installations.

United States solar PV Stats as a country
