Solar PV Analysis of Oakland, United States
Oakland, California, United States, with its latitude of 37.8043514 and longitude of -122.2711639, is a suitable location for solar power generation due to its relatively high average daily solar irradiance across all seasons. During summer, the average energy production per day for each kilowatt of installed solar capacity is 7.04 kWh, while in autumn it decreases to 4.36 kWh/day, further drops to 3.06 kWh/day in winter, and then increases again to 6.79 kWh/day during spring.
The highest energy production occurs in the summer months as a result of longer daylight hours and more direct sunlight exposure compared to other seasons. However, local weather conditions such as heavy cloud cover or rain may occasionally impact the efficiency of solar panels at this location.
To optimize energy production from solar panels in Oakland throughout the year, it is recommended that fixed panel installations be tilted at an angle of 33 degrees facing southward. This orientation maximizes sunlight absorption by ensuring that panels receive optimal sun exposure during different times of the year.
While Oakland's overall suitability for generating solar power remains strong due to its high levels of irradiance throughout the year, potential challenges such as environmental factors or topography should be considered when installing a solar system in this area. For instance, shading caused by nearby buildings or trees could reduce energy production; therefore, selecting an installation site with minimal obstructions can help ensure greater efficiency.
In conclusion, Oakland's favorable climate and consistent levels of sunlight make it an ideal location for harnessing solar power year-round despite occasional weather-related fluctuations in energy production. By carefully considering factors such as panel tilt angle and installation site selection while avoiding significant impediments like shading from surrounding structures or vegetation, one can maximize their investment in renewable energy through efficient use of available resources at this location.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° 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 Oakland
Seasonal solar PV output for Latitude: 37.8043514, Longitude: -122.2711639 (Oakland, 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 33° South in Oakland, United States
To maximize your solar PV system's energy output in Oakland, United States (Lat/Long 37.8043514, -122.2711639) throughout the year, you should tilt your panels at an angle of 33° 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 Oakland, 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 Oakland, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° 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 | 42° South in Autumn | 52° South in Winter | 30° 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 Oakland, 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 Oakland, 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 Oakland, United States
The topography around Oakland, United States is relatively flat. Areas that are most suited for large-scale solar PV installations include open fields, rooftops, and other areas with minimal obstructions to the sun's rays. Additionally, locations where there is a lot of unobstructed space and good access to roads and infrastructure would also be suitable for large-scale solar PV installations.
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.
