Solar PV Analysis of Rancho Cucamonga, United States
Rancho Cucamonga, California, in the United States is generally a good location for generating energy through solar PV systems. This is because it receives a fair amount of sunlight all year round. To break it down by season: during summer you can expect to generate about 8.37 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panels you have installed; in autumn this drops slightly to about 5.54 kWh/day; winter sees the least production at around 3.97 kWh/day; and spring bounces back up with an estimated output of about 7.72 kWh/day.
So, if we look at these numbers, the best times of year to generate solar energy in Rancho Cucamonga would be during summer and spring when sunlight is most abundant.
For fixed panel installations at this location, tilting your panels at an angle of 30 degrees towards the South will help maximize your total yearly production from your solar PV system.
As far as environmental or local factors that could potentially hinder solar production here - there aren't any significant ones that stand out for Rancho Cucamonga specifically. However, like anywhere else, things such as dust or debris on the panels can reduce their efficiency over time so regular cleaning will ensure they work optimally.
Weather conditions like heavy rain or snowfall could also affect power generation but these are not typical weather patterns for this area given its subtropical climate which tends to be warm and dry most of the year.
To sum up: Rancho Cucamonga has favorable conditions overall for harnessing solar energy throughout much of the year with no major obstacles expected due to local factors or weather conditions.
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 Rancho Cucamonga
Seasonal solar PV output for Latitude: 34.1059, Longitude: -117.5859 (Rancho Cucamonga, 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 Rancho Cucamonga, United States
To maximize your solar PV system's energy output in Rancho Cucamonga, United States (Lat/Long 34.1059, -117.5859) 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 Rancho Cucamonga, 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 Rancho Cucamonga, 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 | 27° 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 Rancho Cucamonga, 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 Rancho Cucamonga, 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 Rancho Cucamonga, United States
Rancho Cucamonga is located in the San Bernardino County in California, United States. The topography of this area consists mainly of flat plains at the base of a range of mountains, specifically the San Gabriel Mountains to its north and the smaller hills of Chino Hills to its south.
The city is situated within a valley region and has an average elevation around 1,200 feet or 370 meters above sea level. Its climate can be characterized as warm-summer Mediterranean with hot summers and mild winters - ideal for solar energy production.
For large-scale solar PV installations, areas that are most suitable would typically be those with high levels of sunlight exposure (insolation), relatively flat terrain for ease of installation, and minimal obstructions such as tall buildings or trees which could block sunlight.
Given these criteria, potential locations near Rancho Cucamonga might include:
1) Flatlands surrounding the city: These areas receive ample sunshine throughout most parts of the year which makes them ideal for large-scale solar farms.
2) Desert regions: Eastwards towards Mojave desert could also be considered due to their high insolation rates although transportation and maintenance costs might increase because they're farther from populated areas.
3) Rooftops on commercial/industrial buildings: If land availability is an issue, installing solar panels on rooftops can also be a good option especially on larger commercial or industrial buildings within Rancho Cucamonga's urban area where there's already existing infrastructure.
However, any proposed location would need thorough assessment considering various factors including environmental impact assessments before proceeding with installation.
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.
