Desert Hot Springs, California is a pretty good place for generating solar energy all year round. This is because it's located in the Northern Sub Tropics where there's lots of sunshine. In simple terms, the amount of electricity you can get from a solar panel depends on how much sunlight it gets. The more sun, the more power.
In this location, during summer you can expect to generate about 8.21 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panels you have installed. In autumn, that number goes down to about 5.56 kWh/day; in winter it's around 3.98 kWh/day; and in spring it rises again to about 7.78 kWh/day.
To get the most out of your solar panels at this location throughout the year, they should be tilted at an angle of 30 degrees facing south.
Now let's talk about things that could potentially interfere with your solar energy production here:
Since Desert Hot Springs is indeed a desert area, dust and dirt are common which can cover up your panels and reduce their efficiency over time if not cleaned regularly. So one preventative measure would be regular cleaning or installing self-cleaning technology for your panels.
Another issue could be high temperatures - while sunny days are great for producing solar energy, extreme heat can actually make your system less efficient by overheating them - so ensuring adequate ventilation and cooling systems would help prevent this problem.
Lastly there might be local regulations or building codes regarding installation of such systems which need to be checked before installing any kind of renewable energy resource at home or business premises.
So overall while Desert Hot Springs is quite ideal for generating solar power due to its sunny climate year-round but attention must also given towards maintenance and compliance with local rules & regulations too!
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 Desert Hot Springs
Seasonal solar PV output for Latitude: 33.9657, Longitude: -116.5259 (Desert Hot 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 Desert Hot Springs, United States
To maximize your solar PV system's energy output in Desert Hot Springs, United States (Lat/Long 33.9657, -116.5259) 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 Desert Hot 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 Desert Hot 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 | 49° 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 Desert Hot 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 Desert Hot 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 Desert Hot Springs, United States
Desert Hot Springs, located in the Coachella Valley of Southern California, is characterized by a desert topography. The area consists mainly of flatlands and low-lying hills with sparse vegetation due to its arid climate. It's surrounded by several mountain ranges including San Bernardino Mountains to the north and Santa Rosa Mountains to the south.
The region receives abundant sunlight throughout the year making it highly suitable for large-scale solar photovoltaic (PV) installations. Flat areas with minimal shading are ideal for such projects.
Nearby areas suited for large-scale solar PV would include:
1. Joshua Tree National Park: Although it's a protected area, its outskirts have vast expanses of flat desert land that receive high levels of sunshine annually.
2. Palm Desert: This city has wide open spaces that could be used for solar PV installations.
3. Indio: Located southeast of Desert Hot Springs, this city also has significant open spaces suitable for large scale solar power generation.
4. Coachella Valley: As an expansive desert valley, there are numerous locations within this region that could potentially host large-scale solar facilities.
5. Blythe: This city is located further east but has been identified as another potential site due to its high sun exposure and available lands.
However, any development should consider environmental impacts on local ecosystems and habitats as well as regulatory constraints or protections in place.
United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United States?
Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
