Baldwin Park, California, situated in the Northern Sub Tropics, offers a favorable location for solar PV energy generation throughout the year. The city's geographical position at latitude 34.0862 and longitude -117.9641 provides ample sunlight for consistent solar power production.
Seasonal Solar Performance
Solar energy output in Baldwin Park varies across seasons, with summer being the most productive period. During summer months, solar panels can generate an impressive 8.37 kWh per day for each kilowatt of installed capacity. Spring follows closely, with a daily output of 7.72 kWh/kW. Autumn sees a moderate decrease to 5.54 kWh/day, while winter experiences the lowest production at 3.97 kWh/day per kW installed.
Optimal Times for Solar Generation
The most ideal times for solar energy production in Baldwin Park are from late spring through early fall. This period, roughly spanning from May to September, offers longer daylight hours and more direct sunlight, maximizing solar panel efficiency. However, the region's generally sunny climate allows for significant energy generation throughout the year, even during the less productive winter months.
Panel Tilt for Maximum Efficiency
For fixed panel installations in Baldwin Park, the optimal tilt angle to maximize year-round solar production is 30 degrees facing South. This angle ensures that panels capture the most sunlight possible across all seasons, balancing the sun's changing position throughout the year.
Environmental and Weather Considerations
While Baldwin Park's climate is generally conducive to solar energy production, there are a few factors to consider:
- Occasional smog and air pollution from the Los Angeles metropolitan area may slightly reduce solar panel efficiency.
- Infrequent Santa Ana winds can bring dust, potentially affecting panel performance.
To mitigate these issues, regular cleaning and maintenance of solar panels is recommended. Additionally, installing panels at a slight angle can help prevent dust accumulation. Using high-quality, dust-resistant panels can also enhance long-term performance in this environment.
Overall, Baldwin Park's location proves to be highly suitable for solar PV energy generation, with minimal environmental or weather-related impediments to consistent and efficient solar production throughout the year.

Solar output per kW of installed solar PV by season in Baldwin Park
Seasonal solar PV output for Latitude: 34.0862, Longitude: -117.9641 (Baldwin Park, 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 Baldwin Park, United States
To maximize your solar PV system's energy output in Baldwin Park, United States (Lat/Long 34.0862, -117.9641) 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 Baldwin Park, 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 Baldwin Park, 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 Baldwin Park, 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 Baldwin Park, 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 Baldwin Park, United States
Baldwin Park, located in Los Angeles County, California, is situated in a relatively flat area within the San Gabriel Valley. The topography of the region surrounding Baldwin Park is characterized by a mix of urban development and natural features. To the north and northeast of Baldwin Park, the terrain gradually rises towards the foothills of the San Gabriel Mountains. These mountains form a dramatic backdrop to the area, with steep slopes and rugged peaks that contrast sharply with the flat valley floor. The San Gabriel Mountains reach elevations of over 10,000 feet at their highest points, though the foothills nearest to Baldwin Park are much lower. To the south and west of Baldwin Park, the landscape remains predominantly flat, typical of the Los Angeles Basin. This area is heavily urbanized, with a dense network of roads, residential neighborhoods, and commercial developments. Despite the urban nature of the region, there are still some open spaces and parks scattered throughout.
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 location would have ample open space, relatively flat terrain, and good sun exposure. One potential area for large-scale solar PV development could be the less developed regions to the east and southeast of Baldwin Park, towards the Puente Hills. These areas have more open land and gentler slopes compared to the mountainous regions to the north. Another possibility might be repurposing some of the industrial areas or large commercial properties in the surrounding cities. While not as expansive as undeveloped land, these sites often have large, flat rooftops that could accommodate solar panels. It's important to note that the heavily urbanized nature of the region surrounding Baldwin Park presents challenges for large-scale solar PV installations. Any significant solar projects would likely need to be located further from the city, perhaps in the more open areas of the Mojave Desert to the north and east, where there is abundant sunshine and vast tracts of undeveloped land. Ultimately, the suitability of any specific site for solar PV development would require detailed assessment, taking into account factors such as local zoning laws, environmental considerations, and proximity to existing power infrastructure.United States solar PV Stats as a country
