Solar PV Analysis of Woodside, United States
Solar Energy Potential in Woodside, California
Woodside, California, situated in the Northern Temperate Zone, offers a favorable location for solar energy generation throughout the year. The seasonal variations in solar output provide insights into the effectiveness of photovoltaic (PV) systems in this area.
Summer stands out as the most productive season, with an impressive 7.04 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 6.79 kWh/day. These seasons present ideal conditions for maximizing solar energy production, thanks to longer daylight hours and typically clearer skies.
Autumn sees a moderate decrease in output, yielding 4.36 kWh/day. Winter experiences the lowest production at 3.06 kWh/day, primarily due to shorter days and potentially overcast conditions. However, even during these less productive months, the solar potential remains significant enough to contribute meaningfully to energy needs.
Optimal Panel Placement
For fixed panel installations in Woodside, the ideal tilt angle to maximize year-round solar production is 32 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and seasonal sun positions.
Environmental Considerations
While Woodside generally provides excellent conditions for solar energy production, there are a few environmental factors to consider:
- Fog: The proximity to the San Francisco Bay can lead to occasional morning fog, potentially reducing early-day solar output.
- Tree cover: Woodside's lush vegetation might cast shadows on solar panels, affecting their efficiency.
To mitigate these factors, consider the following preventative measures during solar installation:
- Conduct a thorough shade analysis to identify optimal panel placement, avoiding areas prone to tree shadows.
- Use microinverters or power optimizers to minimize the impact of partial shading on overall system performance.
- Regular tree trimming to maintain clear sun exposure for the panels.
- Consider slightly adjusting the panel angle or using tracking systems in areas frequently affected by morning fog to maximize afternoon sun exposure.
Despite these minor challenges, Woodside's climate and geographical position make it an excellent location for solar energy production, with ample opportunity to harness renewable energy throughout the year.
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 Woodside
Seasonal solar PV output for Latitude: 37.4245, Longitude: -122.296 (Woodside, 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 Woodside, United States
To maximize your solar PV system's energy output in Woodside, United States (Lat/Long 37.4245, -122.296) 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 Woodside, 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 Woodside, 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 | 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 Woodside, 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 Woodside, 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 Woodside, United States
The topography around Woodside, California is quite varied and interesting. Woodside is located in the western foothills of the Santa Cruz Mountains, which gives the area a hilly and often rugged landscape. The terrain generally rises as you move west from the flatter areas near the San Francisco Bay towards the Pacific Ocean.
The immediate vicinity of Woodside features rolling hills covered in a mix of grasslands, oak woodlands, and redwood forests. These hills are intersected by numerous small valleys and canyons, creating a diverse and picturesque landscape. The elevation in Woodside itself ranges from about 200 to 450 feet above sea level, but nearby areas in the Santa Cruz Mountains can reach heights of over 2,000 feet.
To the east of Woodside, the land gradually becomes flatter as it approaches the bay, with more developed suburban areas. To the west, the terrain becomes increasingly mountainous and forested as you enter the heart of the Santa Cruz Mountains.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the topography presents some challenges. Ideal locations for solar farms are typically flat or gently sloping areas with minimal shading from surrounding terrain or vegetation. Given the hilly nature of Woodside and its surroundings, finding suitable large, flat areas can be difficult.
However, some potential areas for solar PV development might include:
- The flatter areas to the east of Woodside, closer to the bay, where there are more open spaces and less dramatic terrain.
- Some of the broader valley floors within the nearby hills, although these may be limited in size.
- Cleared or open areas on some of the gentler hillsides, particularly those with southern exposure for maximum sunlight.
- Repurposed land in more developed areas to the north and east, such as large parking lots or industrial zones, which could be fitted with solar canopies.
It's important to note that any large-scale solar development in this area would need to carefully consider environmental impacts, local zoning regulations, and the preservation of the region's natural beauty, which is highly valued by residents and visitors alike.
