Solar PV Analysis of Willoughby, United States
The location at Willoughby, Ohio is pretty decent for generating energy using solar panels throughout the year. However, it's not perfect as the amount of electricity you can generate varies depending on the season.
In simpler terms, during summer and spring, your solar panels will produce a good amount of electricity - 6.00 kilowatt-hours (kWh) per day in summer and 5.40 kWh/day in spring for every kilowatt (kW) of installed solar panel capacity. This means that these are the best times to generate solar energy at this location.
On the other hand, autumn and winter see a drop in production - 3.29 kWh/day in autumn and just 1.79 kWh/day in winter per kW of installed solar panel capacity.
For optimal performance all year round from your solar panels in Willoughby, Ohio, they should be tilted at an angle of 36 degrees facing south.
However, there could be some local factors that might hinder your ability to generate maximum power from your panels such as weather conditions including cloud cover or snowfall which are common during winters in Ohio. These conditions reduce sunlight reaching the panels thereby limiting their output.
To overcome this challenge and ensure greater energy production year-round despite these impediments:
1) You can install automated cleaning systems or regularly clean off any snow buildup manually from your panels to allow them absorb as much sunlight as possible.
2) Additionally installing tracking mounts instead of fixed ones could help because they move with sun ensuring maximum exposure throughout day but they're more expensive than fixed mounts.
3) Also consider installing battery storage system so you can store excess power generated during peak sunshine hours or seasons for use when generation dips due to poor weather conditions.
4) Lastly regular maintenance checks will ensure optimum performance by identifying issues early before they impact productivity significantly.
Remember though while these measures may improve efficiency each comes with its own costs and should be considered against potential gains.
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 Willoughby
Seasonal solar PV output for Latitude: 41.6325, Longitude: -81.4034 (Willoughby, 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 36° South in Willoughby, United States
To maximize your solar PV system's energy output in Willoughby, United States (Lat/Long 41.6325, -81.4034) throughout the year, you should tilt your panels at an angle of 36° 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 Willoughby, 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 Willoughby, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 45° South in Autumn | 56° South in Winter | 34° 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 Willoughby, 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 Willoughby, 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 Willoughby, United States
Willoughby, United States is located in the state of Ohio and falls under Lake County. The topography around Willoughby is generally flat with occasional rolling hills. It is part of the Great Lakes region, which has numerous rivers and lakes.
For large-scale solar PV installations, areas with maximum sun exposure and minimal shading are ideal. Flat or gently sloping lands are preferred to reduce installation costs. Considering these factors, open fields or farmlands around Willoughby could be potential locations for large-scale solar PV systems.
However, it's important to note that while Ohio gets a decent amount of sunlight throughout the year (around 4-4.5 hours per day on average), it's not as high compared to states in the southwestern U.S., like Arizona or California which receive more than 6 hours per day on average.
Furthermore, factors such as local zoning laws & regulations, proximity to power grids for easy connection & transmission of electricity generated from solar panels should also be taken into account when considering suitability for large scale solar PV installations.
Lastly, conducting a detailed site-specific assessment would provide a more accurate understanding about its suitability for large-scale solar PV system 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.
