Solar PV Analysis of Cottage Grove, United States
Based on the information given, it's clear that Cottage Grove, Minnesota is a decent place for generating solar energy all year round. The amount of electricity you can make with your solar panels changes throughout the year and depends on how much sunlight they get.
In summer, you can expect to generate around 6.70 kilowatt-hours (kWh) per day for every kilowatt (kW) of solar panels you have installed. This is when your system will produce the most power because there are more hours of daylight and the sun is at its highest in the sky.
In autumn and spring, your system will still produce a good amount of power - about 3.38 kWh/day in autumn and 5.20 kWh/day in spring per kW of installed solar.
Winter will be your least productive time due to shorter days and less intense sunlight; during this season you can expect about 2.33 kWh/day per kW of installed solar.
To maximize total production from your solar panel system throughout the year, tilt them at an angle facing south by 39 degrees; this is because we're located in Northern Hemisphere where tilting panels towards south captures maximum sunlight.
There may be some local factors that could affect how much electricity your system produces - things like cloudy weather or snow covering up your panels would reduce their output significantly since they need direct sunlight to work properly.
Preventative measures include installing sensors that alert when there's too much shade or debris on the panels so they can be cleaned off promptly; also consider using black-colored panels which absorb more heat than other colors making them better at melting off any snow that might accumulate during winter months.
Remember though, even with these potential challenges, Cottage Grove still has enough sunny days throughout each season to make installing a solar PV system worthwhile!
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 Cottage Grove
Seasonal solar PV output for Latitude: 44.8306, Longitude: -92.9393 (Cottage Grove, 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 39° South in Cottage Grove, United States
To maximize your solar PV system's energy output in Cottage Grove, United States (Lat/Long 44.8306, -92.9393) throughout the year, you should tilt your panels at an angle of 39° 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 Cottage Grove, 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 Cottage Grove, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 28° South in Summer | 49° South in Autumn | 58° South in Winter | 38° 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 Cottage Grove, 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 Cottage Grove, 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 Cottage Grove, United States
Cottage Grove, located in Washington County, Minnesota, United States is characterized by relatively flat terrain with some rolling hills. The area is part of the Upper Midwest region and has a mix of forests, farmland and developed areas.
Regarding solar PV potential, large-scale solar farms require large tracts of land that are relatively flat for optimal sun exposure. Therefore, unused or less productive agricultural lands could be suitable for this purpose around Cottage Grove. Additionally, rooftops of large commercial or industrial buildings within the city could also be viable locations for smaller-scale solar installations.
However, it's important to note that the suitability for solar PV doesn't solely depend on topography but also factors like local climate (amount of sunlight), zoning regulations and proximity to power grids. A detailed site-specific assessment would be required to determine the most suitable areas for large-scale solar PV installations in and around Cottage Grove.
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.
