Solar PV Analysis of San Leandro, United States
San Leandro, California, situated in the Northern Temperate Zone, offers a relatively favorable location for solar energy generation throughout the year. The city's geographic position at latitude 37.722 and longitude -122.1643 provides ample sunlight for photovoltaic (PV) systems, though with notable seasonal variations.
Seasonal Solar Performance
Solar energy production in San Leandro peaks during the summer months, with an impressive average daily output of 7.04 kWh per kW of installed solar capacity. Spring follows closely behind, generating 6.79 kWh/day. These seasons present ideal conditions for maximizing solar energy harvesting.
Autumn sees a moderate decline in solar production, with an average of 4.36 kWh/day. Winter experiences the lowest output at 3.06 kWh/day, primarily due to shorter daylight hours and potentially overcast conditions. Despite this seasonal dip, San Leandro's solar potential remains relatively strong year-round compared to many other locations.
Optimal Panel Installation
For fixed-panel installations in San Leandro, the ideal tilt angle to maximize year-round solar production is 33 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the sun's changing position in the sky across seasons.
Environmental Considerations
While San Leandro generally provides favorable conditions for solar energy production, there are a few environmental factors to consider:
- Fog: The Bay Area's famous fog can occasionally reduce solar efficiency, particularly during morning hours in summer and fall.
- Air pollution: Being part of the San Francisco Bay Area, San Leandro may experience periods of reduced air quality, which can slightly diminish solar panel efficiency.
To mitigate these factors, consider installing panels at a slightly steeper angle to allow morning fog to roll off more easily. Regular cleaning of panels can also help maintain efficiency by removing any accumulated particulate matter from air pollution.
Overall, San Leandro's climate and geographical location make it a highly suitable area for solar PV installations, with strong potential for energy generation throughout the year, particularly from spring through fall.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in San Leandro
Seasonal solar PV output for Latitude: 37.722, Longitude: -122.1643 (San Leandro, 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 33° South in San Leandro, United States
To maximize your solar PV system's energy output in San Leandro, United States (Lat/Long 37.722, -122.1643) throughout the year, you should tilt your panels at an angle of 33° 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 San Leandro, 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 San Leandro, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° South in Summer | 42° South in Autumn | 52° South in Winter | 30° 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 San Leandro, 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 San Leandro, 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 San Leandro, United States
The topography around San Leandro, California, is characterized by a mix of flat lowlands and gently rolling hills. The city itself is situated on relatively level ground near the eastern shore of San Francisco Bay. To the east of San Leandro, the terrain gradually rises into the East Bay Hills, which are part of the larger Pacific Coast Ranges.
The flatlands near the bay, where much of San Leandro is located, were formed by sediment deposits over thousands of years. This area is largely urbanized now, with a mix of residential, commercial, and industrial development. As you move eastward, the land begins to slope upward, offering views of the bay and surrounding areas.
The nearby hills, while not particularly high compared to mountain ranges, provide a noticeable contrast to the flatlands. These hills are characterized by grassy slopes, scattered oak trees, and some areas of denser vegetation in canyons and on north-facing slopes. The highest points in the immediate vicinity reach elevations of around 1,000 to 1,500 feet above sea level.
Areas Suitable 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 the following characteristics:
- Ample sunlight exposure throughout the year
- Relatively flat terrain for easier installation and maintenance
- Proximity to existing power infrastructure
- Minimal environmental impact
- Adequate land availability
Given these criteria, the most suitable areas for large-scale solar PV near San Leandro would likely be:
1. The flatlands to the east and southeast of San Leandro, particularly in less developed areas of Alameda County. These areas offer level ground and good sun exposure.
2. Former industrial or brownfield sites within San Leandro or neighboring cities. These locations often have large, flat areas and are already connected to power grids.
3. The more gently sloping areas at the base of the East Bay Hills, where there might be less urban development and still relatively easy access.
4. Portions of the Altamont Pass area, further east of San Leandro, which is already home to wind farms and has the infrastructure and space for solar installations.
It's important to note that any large-scale solar project would need to undergo thorough environmental and zoning reviews, as well as consider the impact on local communities and ecosystems. The proximity to urban areas and the limited availability of large, undeveloped tracts of land in this region may pose challenges for extensive solar PV installations.
