Tarzana, California, located in the Northern Sub Tropics, offers a favorable environment for solar energy generation throughout the year. With its geographical coordinates at 34.1671° N latitude and 118.5373° W longitude, this location benefits from abundant sunshine and mild temperatures, making it well-suited for solar photovoltaic (PV) installations.

Seasonal Solar Performance

The solar energy output in Tarzana varies across seasons, with summer being the most productive period. During summer months, solar panels can generate an impressive 8.42 kWh per day for each kilowatt of installed capacity. Spring follows closely, with a daily output of 7.54 kWh/kW. Autumn sees a moderate decrease in production, yielding 5.40 kWh/kW per day. Winter, while less productive, still maintains a respectable output of 3.82 kWh/kW daily.

Optimal Panel Placement

For fixed panel installations in Tarzana, the ideal tilt angle to maximize year-round solar production is 30 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.

Peak Generation Periods

The most ideal times for solar energy generation in Tarzana are during the summer months, typically from June through August. These months offer longer daylight hours and more direct sunlight, resulting in peak energy production. Spring and early autumn also provide excellent conditions for solar generation, with clear skies and moderate temperatures contributing to high efficiency.

Environmental Considerations

While Tarzana's climate is generally conducive to solar energy production, there are a few environmental factors to consider: 1. Smog and air pollution: Being part of the Los Angeles metropolitan area, Tarzana can experience periods of poor air quality, which may slightly reduce solar panel efficiency. 2. Santa Ana winds: These strong, dry winds can carry dust and debris, potentially affecting panel performance. To mitigate these issues, regular cleaning and maintenance of solar panels is recommended. Installing panels at a slight angle can also help prevent dust accumulation. Additionally, using high-quality, dust-resistant panels can improve long-term performance in this environment. Overall, Tarzana's climate and geographical location make it an excellent choice for solar PV installations, with the potential for significant energy generation throughout the year, particularly during the summer and spring seasons.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Tarzana

Seasonal solar PV output for Latitude: 34.1671, Longitude: -118.5373 (Tarzana, 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 30° South in Tarzana, United States

To maximize your solar PV system's energy output in Tarzana, United States (Lat/Long 34.1671, -118.5373) throughout the year, you should tilt your panels at an angle of 30° 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 Tarzana, 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 Tarzana, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
18° South in Summer	39° South in Autumn	49° South in Winter	27° 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 Tarzana, 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 Tarzana, 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 Tarzana, United States

The area around Tarzana, located in the San Fernando Valley region of Los Angeles, California, has a varied topography characterized by both flat and hilly terrain. Tarzana itself sits at the base of the Santa Monica Mountains, which rise to the south of the community.

The immediate vicinity of Tarzana is relatively flat, typical of the San Fernando Valley floor. This area is largely urbanized, with residential neighborhoods and commercial districts. As you move south from Tarzana, the terrain becomes increasingly hilly as it transitions into the Santa Monica Mountains. These hills provide scenic views but also create more challenging terrain for development.

To the north of Tarzana, the landscape remains mostly flat, extending across the San Fernando Valley. This area includes other suburban communities and some remaining agricultural lands. To the east and west, the topography is similar, with a mix of flat valley areas and rolling hills as you approach the edges of the valley.

Regarding areas suited for large-scale solar PV (photovoltaic) installations, the flat portions of the San Fernando Valley would be most appropriate. These areas offer the following advantages:

• Ample sunlight exposure due to the lack of obstructions
• Easier construction and maintenance on level ground
• Potentially larger contiguous areas for expansive installations

Specifically, the areas north of Tarzana, extending towards the center of the San Fernando Valley, would be most suitable. However, it's important to note that much of this land is already developed, so large-scale solar installations would likely need to be integrated into existing structures or placed on available open spaces.

The hilly areas to the south, while receiving good sun exposure, would be less ideal for large-scale solar PV due to the challenges of installation on uneven terrain and potential shading issues from the topography itself.

It's worth mentioning that the Los Angeles area, including Tarzana and its surroundings, experiences abundant sunshine year-round, making it generally favorable for solar energy production. However, the dense urban development in much of the region may limit opportunities for very large-scale solar installations close to Tarzana itself.
