Brooklyn, Wisconsin, located in the Northern Temperate Zone at coordinates 42.8536, -89.3704, offers a varied potential for solar energy generation throughout the year. The location experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Production
Summer stands out as the most productive season for solar energy in Brooklyn, with an average daily output of 6.34 kWh per kW of installed solar capacity. Spring follows as the second-best season, yielding 5.27 kWh/day. Autumn sees a considerable drop in production to 3.43 kWh/day, while winter experiences the lowest output at 2.36 kWh/day.
The substantial difference between summer and winter production highlights the impact of seasonal variations on solar energy generation in this location. The longer days and higher sun angle during summer months contribute to peak performance, making it an ideal time for solar energy harvesting.
Optimal Panel Installation
For fixed panel installations in Brooklyn, the ideal tilt angle to maximize year-round solar production is 37 degrees facing south. This angle is calculated based on the location's latitude and seasonal sun positions, ensuring optimal exposure throughout the year.
Environmental Considerations
While Brooklyn's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Snow accumulation during winter months can temporarily reduce panel efficiency.
- Cloudy days, particularly common in autumn and winter, may impact overall production.
To mitigate these issues, consider installing panels at a steeper angle to promote snow shedding and using high-efficiency panels that perform well in low-light conditions. Regular maintenance, including snow removal, can also help maintain optimal performance year-round.
In conclusion, while Brooklyn, Wisconsin experiences significant seasonal variations in solar output, proper panel installation and maintenance can help maximize energy production throughout the year, making solar PV a viable renewable energy option for this location.

Ideally tilt fixed solar panels 37° South in Brooklyn, Wisconsin, United States
To maximize your solar PV system's energy output in Brooklyn, Wisconsin, United States (Lat/Long 42.8536, -89.3704) throughout the year, you should tilt your panels at an angle of 37° 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 Brooklyn, Wisconsin, 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 Brooklyn, Wisconsin, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 47° South in Autumn | 56° South in Winter | 36° 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.

Topography for solar PV around Brooklyn, Wisconsin, United States
The area around Brooklyn, United States, located at approximately 42.8536° North latitude and 89.3704° West longitude, is characterized by gently rolling terrain typical of southern Wisconsin. This region, part of the Midwest's Driftless Area, features a mix of low hills, shallow valleys, and relatively flat expanses. The landscape has been shaped by ancient glacial activity, resulting in a subtle, undulating topography that gradually transitions between modest elevations. The surrounding countryside is primarily composed of agricultural land, interspersed with patches of woodland and small waterways. The terrain is generally open, with few steep slopes or significant elevation changes. This gentle landscape is punctuated by occasional drumlins, which are elongated hills formed by glacial ice movement, adding slight variations to the otherwise subtle contours of the land.
Suitable Areas for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations in the vicinity of Brooklyn, several areas show promise due to their topographical and land-use characteristics. The most suitable sites for solar PV development would likely be found in the open agricultural lands that dominate the region. These areas offer several advantages for solar energy production: Firstly, the relatively flat or gently sloping terrain of former croplands or pastures provides ideal conditions for the installation of solar panels. These sites typically require minimal grading or land preparation, reducing construction costs and environmental impact. Secondly, the open nature of the landscape means there are fewer obstructions that could cast shadows on solar arrays, maximizing potential sunlight exposure throughout the day. The lack of tall vegetation or buildings in many of these rural areas ensures optimal solar energy capture. Lastly, the existing network of rural roads and electrical infrastructure in the agricultural areas surrounding Brooklyn could facilitate the construction and grid connection of solar facilities, making these locations logistically appealing for large-scale PV projects. While specific site selection would require detailed environmental and technical assessments, the general topography and land use patterns in the region surrounding Brooklyn offer numerous potential locations suitable for the development of large-scale solar PV installations.United States solar PV Stats as a country
