Solar PV Analysis of Delano, United States
Delano, California, located in the Northern Temperate Zone, offers a generally favorable environment for solar PV energy generation throughout the year. With coordinates of 35.7768° N latitude and 119.2414° W longitude, this location experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Solar energy output at this location varies considerably across seasons. Summer proves to be the most productive period, with an impressive 8.60 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 7.74 kWh/day/kW. Autumn sees a moderate decline to 5.12 kWh/day/kW, while winter experiences the lowest output at 3.46 kWh/day/kW.
The substantial difference between summer and winter production highlights the impact of seasonal changes on solar energy generation in Delano. This variation is primarily due to changes in day length and sun angle throughout the year.
Optimal Panel Tilt
For fixed panel installations in Delano, the ideal tilt angle to maximize year-round solar production is 31 degrees facing south. This angle optimizes the panels' exposure to sunlight across all seasons, balancing the high summer sun with the lower winter sun angle.
Best Times for Solar Generation
The most ideal times for solar energy generation in Delano are during the summer months, typically from June through August. These months offer long days with high sun angles, resulting in maximum solar panel efficiency. Spring and early fall also provide excellent conditions for solar energy production.
Environmental Factors and Mitigation
While Delano's climate is generally conducive to solar energy production, there are a few environmental factors to consider:
- Dust and agricultural particulates: Delano's location in an agricultural area may lead to dust accumulation on solar panels, potentially reducing efficiency. Regular cleaning and maintenance can mitigate this issue.
- Extreme heat: Summer temperatures in Delano can be very high, which may slightly reduce panel efficiency. Ensuring proper ventilation behind the panels can help manage this concern.
Despite these minor challenges, Delano remains an excellent location for solar PV installations. With proper planning and maintenance, solar energy systems in this area can provide substantial and reliable clean energy throughout the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Delano
Seasonal solar PV output for Latitude: 35.7768, Longitude: -119.2414 (Delano, 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 31° South in Delano, United States
To maximize your solar PV system's energy output in Delano, United States (Lat/Long 35.7768, -119.2414) throughout the year, you should tilt your panels at an angle of 31° 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 Delano, 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 Delano, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 20° South in Summer | 40° South in Autumn | 50° South in Winter | 28° 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 Delano, 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 Delano, 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 Delano, United States
The area around Delano, California, is characterized by relatively flat terrain typical of the southern San Joaquin Valley. This region is part of the larger Central Valley, known for its expansive agricultural lands and gentle topography. The landscape around Delano is predominantly level, with only slight variations in elevation across the immediate vicinity.
To the east of Delano, the terrain gradually begins to rise as it approaches the foothills of the Sierra Nevada mountain range. However, this transition occurs over a considerable distance, and the area immediately surrounding Delano remains quite flat. To the west, the land continues its level nature for many miles before eventually rising into the Coast Ranges.
The flat topography of this region is a result of centuries of sediment deposition from rivers flowing out of the surrounding mountains, creating a vast alluvial plain. This geological history has left the area with rich, fertile soils that have made it ideal for agriculture, which is the dominant land use in and around Delano.
Areas Suitable for Large-Scale Solar PV
The topography and climate of the region surrounding Delano make it well-suited for large-scale solar photovoltaic (PV) installations. Several factors contribute to this suitability:
1. Flat terrain: The level landscape provides ideal conditions for solar panel installation, minimizing the need for extensive land preparation and allowing for optimal panel orientation.
2. Abundant sunshine: The San Joaquin Valley experiences a high number of sunny days throughout the year, maximizing potential solar energy generation.
3. Large open spaces: The expansive agricultural lands in the area could potentially be repurposed or dual-used for solar installations without significantly impacting food production.
Specific areas that might be particularly well-suited for large-scale solar PV projects include:
- Fallow or less productive agricultural lands to the west and southwest of Delano
- Open areas between Delano and nearby towns such as McFarland to the north or Earlimart to the south
- Undeveloped lands east of Delano, before reaching the Sierra foothills
It's important to note that any large-scale solar development would need to consider factors beyond just topography, including local zoning laws, environmental impacts, grid connection capabilities, and community acceptance. However, from a purely topographical standpoint, the flat, sun-drenched lands surrounding Delano offer significant potential for solar energy development.
