Palm Springs, California, offers an excellent location for solar energy generation throughout the year. Situated in the Northern Sub Tropics, this sun-drenched city boasts impressive solar potential across all seasons.
Seasonal Solar Performance
Solar panels in Palm Springs demonstrate strong performance year-round, with peak productivity during the summer months. In summer, each kilowatt of installed solar capacity can generate an impressive 8.21 kWh per day. Spring follows closely behind with 7.78 kWh/day, while autumn sees a moderate decrease to 5.56 kWh/day. Even during winter, when solar output is at its lowest, panels still produce a respectable 3.98 kWh/day per kilowatt installed.
Optimal Panel Tilt
To maximize year-round solar energy production in Palm Springs, fixed solar panels should be installed at a 30-degree tilt facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for seasonal variations in the sun's position.
Ideal Generation Periods
The most productive periods for solar generation in Palm Springs are from late spring through early fall. During these months, longer days and more direct sunlight contribute to higher energy yields. However, the city's abundant sunshine ensures significant solar production even during the winter months.
Environmental Considerations
While Palm Springs is generally ideal for solar energy, there are a few environmental factors to consider:
- Dust and sand: The desert environment can lead to dust accumulation on panels, potentially reducing efficiency.
- Extreme heat: Very high temperatures during summer may slightly decrease panel efficiency.
To mitigate these issues, regular panel cleaning is recommended to remove dust buildup. Additionally, ensuring proper ventilation during installation can help manage heat-related efficiency losses. Despite these minor challenges, Palm Springs remains an exceptional location for solar energy production, with its abundant sunshine far outweighing any potential drawbacks.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° 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 Palm Springs
Seasonal solar PV output for Latitude: 33.7983, Longitude: -116.5106 (Palm Springs, 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 Palm Springs, United States
To maximize your solar PV system's energy output in Palm Springs, United States (Lat/Long 33.7983, -116.5106) 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 Palm Springs, 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 Palm Springs, 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 | 48° South in Winter | 26° 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 Palm Springs, 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 Palm Springs, 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 Palm Springs, United States
The topography around Palm Springs, California, is quite diverse and dramatic. The city itself sits in the Coachella Valley, a desert basin surrounded by mountains. To the west and north, you'll find the impressive San Jacinto Mountains, which rise steeply from the valley floor. These mountains create a striking backdrop for the city, with peaks reaching over 10,000 feet in elevation.
To the south and east of Palm Springs, the landscape transitions into the Santa Rosa Mountains, which are slightly lower in elevation but still form a significant part of the area's topography. The valley floor around Palm Springs is relatively flat, with a gentle slope descending from northwest to southeast.
The region is characterized by its desert climate, with sparse vegetation consisting mainly of drought-resistant plants like cacti, Joshua trees, and desert shrubs. The valley floor is primarily composed of alluvial fans and desert pavement, created by centuries of erosion from the surrounding mountains.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the open desert areas to the east and southeast of Palm Springs offer the most potential. These areas, extending into the eastern part of the Coachella Valley and beyond, provide several advantages for solar energy production:
1. Abundant flat land: The desert landscape offers vast expanses of level terrain, which is ideal for installing large solar panel arrays without the need for extensive grading or land preparation.
2. High solar irradiance: This region experiences a high number of sunny days per year and intense sunlight, making it excellent for solar energy generation.
3. Low population density: The areas east of Palm Springs are sparsely populated, reducing potential conflicts with residential or commercial development.
4. Proximity to existing infrastructure: The presence of nearby towns and cities means that the necessary electrical grid connections are not too far away.
5. Limited agricultural value: The arid nature of these lands means they have little value for traditional agriculture, making solar development a more attractive land use option.
Some specific areas that could be suitable for large-scale solar PV installations include the desert regions near Desert Hot Springs, Thousand Palms, and extending towards the Salton Sea. However, it's important to note that any solar development would need to consider environmental impacts, particularly on desert ecosystems and wildlife, as well as comply with local, state, and federal regulations.
