Solar Energy Potential in Pico Rivera, California
Pico Rivera, California, located in the Northern Sub Tropics at coordinates 33.9893, -118.089, offers good conditions for solar energy production throughout the year, though with significant seasonal variations. The location experiences strong solar potential, particularly during the warmer months. Solar energy production at this location follows a predictable seasonal pattern. Summer yields the highest output at 7.12kWh per day for each kilowatt of installed capacity. Spring follows closely with 6.82kWh/day. Energy production decreases in autumn to 4.79kWh/day, with winter showing the lowest output at 3.66kWh/day per kilowatt installed.Optimal Installation Angle
For fixed panel installations in Pico Rivera, the ideal tilt angle to maximize year-round solar production is 30 degrees facing South. This angle optimizes the balance between summer and winter sun exposure, accounting for the sun's changing position throughout the year.Seasonal Considerations
The late spring through early fall period (May through September) represents the prime solar generation window for this location. During these months, longer days and more direct sunlight create optimal conditions for solar energy production. While winter months produce significantly less energy, the mild Southern California climate means solar production continues year-round, unlike in more northern regions.Environmental Factors
Several environmental factors could potentially impact solar production in Pico Rivera:- Coastal morning fog and marine layer intrusions can reduce morning production, particularly during spring and early summer months
- Air pollution from the greater Los Angeles metropolitan area may reduce solar irradiance, especially during temperature inversions
- Santa Ana wind events can bring dust that temporarily reduces panel efficiency if not cleaned regularly
- Occasional wildfire smoke during fire season (typically late summer through fall) can significantly reduce solar production
Preventative Measures
To maximize solar energy production in Pico Rivera, several preventative measures are recommended. Regular panel cleaning is essential to remove dust accumulation, particularly following Santa Ana wind events. Installing panels with anti-soiling coatings can reduce the impact of dust and pollution. Microinverters or power optimizers can help mitigate production losses from partial shading. Additionally, slightly oversizing the solar array relative to inverter capacity can help capture more energy during less-than-ideal conditions, ensuring more consistent production throughout the year. Despite these minor challenges, Pico Rivera's climate makes it an excellent location for solar energy production, with annual output significantly higher than the national average.Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 30° South in Pico Rivera, United States
To maximize your solar PV system's energy output in Pico Rivera, United States (Lat/Long 33.9893, -118.089) 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 Pico Rivera, 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 Pico Rivera, 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 | 38° South in Autumn | 48° 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 Pico Rivera, 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 Pico Rivera, 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 Pico Rivera, United States
The topography around Pico Rivera, California presents a diverse landscape shaped by both natural and urban development. Situated in Los Angeles County, Pico Rivera lies within the southeastern portion of the Los Angeles Basin, approximately 11 miles southeast of downtown Los Angeles. The city occupies a relatively flat area at an elevation of around 200 feet (61 meters) above sea level. The most prominent natural feature in the vicinity is the Rio Hondo River, which flows along the western boundary of Pico Rivera, and the San Gabriel River, which defines its eastern edge. These waterways have historically shaped the landscape, creating a broad, gently sloping alluvial plain composed of sediments deposited over millennia. This flat terrain was formed by ancient flooding events that carried materials down from the San Gabriel Mountains to the north.
Surrounding Terrain Features
Looking northward from Pico Rivera, the terrain gradually rises toward the foothills of the San Gabriel Mountains, which stand prominently on the horizon approximately 15-20 miles away. These mountains, part of the Transverse Ranges, reach elevations exceeding 10,000 feet and create a dramatic backdrop to the otherwise level landscape of the Los Angeles Basin. To the south and southwest, the topography remains predominantly flat as it extends toward the Pacific Ocean, about 20 miles distant. This flat expanse is characteristic of the Los Angeles Basin, which forms a broad coastal plain bounded by mountains to the north and east. The Puente Hills rise to the east and northeast of Pico Rivera, creating a modest but noticeable topographic feature. These hills, reaching heights of approximately 1,400 feet, represent a natural boundary between the San Gabriel Valley and the coastal plain.Urban Landscape
The natural topography of the area has been significantly modified by urban development. Pico Rivera itself is heavily urbanized, with residential neighborhoods, commercial districts, and industrial areas covering much of the natural landscape. The city's layout follows a typical grid pattern, with streets and buildings occupying the flat terrain that once consisted of agricultural fields and natural floodplains.Potential Areas for Solar PV Development
When considering locations suitable for large-scale solar photovoltaic (PV) development near Pico Rivera, several factors must be evaluated, including available open space, topography, and existing land use patterns. The flat terrain of the Los Angeles Basin theoretically provides ideal conditions for solar PV installations, as it minimizes construction challenges and maximizes solar exposure. However, the dense urban development throughout much of the region significantly limits available space for large-scale projects. The most promising areas for substantial solar PV development would likely be found in the less densely populated regions to the east and northeast, particularly in portions of the San Gabriel Valley and areas approaching the Puente Hills. These locations offer relatively flat or gently sloping terrain that would be conducive to solar array construction. Industrial zones within and around Pico Rivera also present opportunities for solar development, particularly on large warehouse rooftops or in brownfield sites where other development might be restricted. The extensive industrial corridors along the I-605 and SR-60 freeways contain numerous large buildings with substantial roof areas that could support significant solar installations. The flood control basins associated with the Rio Hondo and San Gabriel Rivers represent another potential opportunity. These large, open areas serve primarily for flood management but could potentially accommodate dual-use solar installations designed to coexist with their flood control functions. Further east, the Chino Hills area offers more open space with suitable topography for solar development, though environmental considerations and land use designations would need to be carefully evaluated. Similarly, portions of northern Orange County to the southeast feature terrain that would be physically suitable, though again limited by existing development and land use policies. In summary, while the immediate vicinity of Pico Rivera offers limited opportunities for large-scale solar PV development due to extensive urbanization, the broader region contains several areas with favorable topographic conditions that could potentially support significant solar installations, particularly in industrial zones, flood control areas, and less developed portions of the eastern Los Angeles Basin.United States solar PV Stats as a country
