Solar Energy Production in Hume, California

Hume, California, located in the Northern Temperate Zone, presents a variable profile for solar PV energy generation throughout the year. The location experiences significant seasonal fluctuations in solar energy production, with summer being the most productive period at 8.29kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, generating 7.31kWh daily per kilowatt installed. Production decreases considerably in autumn to 5.07kWh per day, while winter represents the lowest output period with just 3.31kWh daily per installed kilowatt. For maximum year-round energy production at this location, fixed solar panels should be installed at a 32-degree tilt facing South. This specific angle has been calculated to optimize annual solar energy capture, taking into account the Earth's elliptical orbit and the site's particular latitude.

Environmental Considerations

Several environmental factors could impact solar production in Hume. Being located in the Sierra Nevada mountains, Hume experiences significant snowfall during winter months, which can cover panels and reduce output during the already low-production winter season. Installing panels at the recommended 32-degree tilt helps with snow shedding, but periodic manual clearing may still be necessary. Forest fires and smoke are another consideration in this region of California. During fire season, ash and particulate matter in the air can significantly reduce solar irradiance reaching panels. While unavoidable, installing microinverters or power optimizers can help minimize production losses when some panels are partially shaded by smoke. Temperature extremes also affect performance. While Hume's cooler mountain climate is generally beneficial for solar panel efficiency compared to hotter valley locations (as panels lose efficiency at high temperatures), the installation should still incorporate adequate airflow beneath panels to prevent overheating during summer months. Finally, the mountainous terrain may create localized shading issues. A thorough site assessment to identify potential shade from nearby trees or topographic features is essential before installation, possibly incorporating shade analysis tools to determine optimal panel placement.

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 Hume

Seasonal solar PV output for Latitude: 36.785, Longitude: -118.9137 (Hume, 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 32° South in Hume, United States

To maximize your solar PV system's energy output in Hume, United States (Lat/Long 36.785, -118.9137) throughout the year, you should tilt your panels at an angle of 32° 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 Hume, 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 Hume, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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	41° South in Autumn	51° South in Winter	29° 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 Hume, 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 Hume, United States.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Hume, United States

The topography around Hume, located in the Sierra Nevada mountains of California, is characterized by dramatic mountainous terrain with significant elevation changes. This area sits within Fresno County, near the Kings Canyon National Park, and features a rugged landscape carved by glacial activity and erosion over millions of years. The immediate vicinity of Hume is dominated by the Kings River watershed, with the settlement itself situated near Hume Lake, a man-made reservoir at approximately 5,200 feet (1,585 meters) elevation. The surrounding terrain rises steeply from this point, with numerous peaks exceeding 8,000 feet (2,438 meters) in the nearby vicinity. Dense coniferous forests cover much of the lower and middle elevations, transitioning to alpine vegetation and exposed rock at higher altitudes.

Topographical Features

The area exhibits classic Sierra Nevada topography with U-shaped valleys, steep granite cliffs, and numerous water features. The Kings River flows through deep canyons in this region, creating dramatic vertical relief. The underlying geology is predominantly granitic, part of the massive Sierra Nevada batholith, with some metamorphic formations present as well. To the east, the terrain becomes increasingly mountainous, eventually reaching the Sierra Nevada crest and the Great Western Divide. To the west, the landscape gradually transitions toward the San Joaquin Valley, with decreasing elevation and gentler slopes. This western transition zone, where the mountains begin to flatten into foothills, represents a significant topographical change.

Solar PV Potential Areas

For large-scale solar photovoltaic development, the immediate mountainous terrain around Hume presents significant challenges due to steep slopes, forest cover, and protected land status within national parks and forests. However, several nearby areas show better potential: The western foothills of the Sierra Nevada, approximately 20-30 miles west of Hume, offer more suitable conditions. These areas feature gentler slopes, lower elevation, and less forest cover. The transition zone between the Sierra foothills and the eastern edge of the San Joaquin Valley provides relatively flat terrain with good solar exposure. Specifically, the areas near Pine Flat Lake and the communities of Piedra, Sanger, and Reedley represent potentially viable locations. These regions benefit from clearer skies and less topographical shading than the higher mountain areas around Hume itself. The land in these western locations also experiences less snow cover during winter months, allowing for more consistent annual energy production. The San Joaquin Valley proper, beginning approximately 35-40 miles west of Hume, offers the most ideal conditions for large-scale solar development in the broader region. This vast, flat agricultural valley has minimal topographical barriers, extensive open space, and established transmission infrastructure. Communities like Fresno, Clovis, and Visalia are situated in areas that combine favorable topography with proximity to existing energy infrastructure and population centers. It's worth noting that while topography is favorable in these western areas, other considerations such as current land use (primarily agriculture), water resources, and ecological impacts would need careful assessment before development. Many of these potentially suitable areas are currently productive agricultural lands, creating competing interests for land use.
