Solar PV Analysis of Grand Blanc, United States
Grand Blanc, Michigan, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. The city experiences significant seasonal variations in solar output, which affects the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Grand Blanc, with an impressive 6.32 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 5.38 kWh/day. However, the output drops considerably during autumn (3.19 kWh/day) and reaches its lowest point in winter (1.98 kWh/day).
These figures highlight the stark contrast between the warm and cold months, with summer producing more than three times the energy of winter. This variation is primarily due to the changing angle of the sun and the number of daylight hours throughout the year.
Optimal Panel Installation
To maximize year-round solar production in Grand Blanc, fixed solar panels should be installed at a 37-degree tilt angle facing south. This angle is calculated to capture the most sunlight across all seasons, balancing the high summer sun with the lower winter sun position.
Environmental and Weather Considerations
Several factors can impact solar production in Grand Blanc:
- Snow accumulation in winter can significantly reduce panel efficiency
- Cloudy weather, common in the region, can decrease solar output
- Tree coverage and shading from nearby structures may limit sun exposure
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding, use micro-inverters or power optimizers to minimize the impact of partial shading, and ensure proper tree trimming and panel placement to maximize sun exposure.
Conclusion
While Grand Blanc's location is not ideal for year-round solar production due to its harsh winters and variable weather, it still offers substantial potential, especially during spring and summer. With proper system design and installation techniques, residents can harness significant solar energy, particularly from March through October.

Solar output per kW of installed solar PV by season in Grand Blanc
Seasonal solar PV output for Latitude: 42.9285, Longitude: -83.6332 (Grand Blanc, 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 37° South in Grand Blanc, United States
To maximize your solar PV system's energy output in Grand Blanc, United States (Lat/Long 42.9285, -83.6332) 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 Grand Blanc, 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 Grand Blanc, 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 | 46° South in Autumn | 57° 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.
Calculate solar panel row spacing in Grand Blanc, 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 Grand Blanc, 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 Grand Blanc, United States
The topography around Grand Blanc, Michigan, in the United States is generally characterized by gently rolling terrain. This area is part of the larger Great Lakes region and was shaped by glacial activity thousands of years ago. The landscape consists of low hills, shallow valleys, and some flat areas interspersed throughout the region.
Grand Blanc itself sits at an elevation of about 860 feet (262 meters) above sea level. The surrounding area doesn't have any dramatic changes in elevation, with most of the terrain varying by only 100 to 200 feet. You'll find a mix of open fields, wooded areas, and numerous small lakes and ponds scattered across the landscape.
To the north and east of Grand Blanc, the terrain becomes slightly more varied as you approach the Flint River valley. Here, you might encounter some steeper slopes and more pronounced hills. To the south and west, the land tends to be flatter, with more expansive open areas.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. The ideal locations would be relatively flat, open areas with minimal shading from trees or buildings. These areas should also have good access to existing power infrastructure.
Based on these criteria, the most suitable areas for solar PV installations near Grand Blanc would likely be found to the south and west of the city. Here, you'll find more expansive agricultural lands and open fields that could potentially be repurposed for solar energy production. These areas tend to have fewer trees and more consistent, flat terrain, which is ideal for maximizing solar exposure throughout the day.
It's worth noting that while the immediate vicinity of Grand Blanc may have suitable locations, expanding the search radius to include more rural areas in Genesee County and neighboring counties could yield even better options for large-scale solar projects. These areas often have larger tracts of open land that could accommodate substantial solar arrays while minimizing conflicts with residential or commercial development.
