Solar PV Analysis of Pontiac, United States
Pontiac, Michigan, located in the Northern Temperate Zone of the United States, has varying levels of solar energy production potential throughout the year. In simple terms, this means that at different times of the year, you can expect to generate different amounts of electricity from a solar panel system.
During summer and spring seasons when days are longer and sunnier, solar panels in Pontiac can produce quite a bit more electricity. Specifically, you could expect about 6.32 kilowatt-hours (kWh) per day for each kilowatt (kW) of your system's capacity during summer and about 5.38 kWh/day/kW in spring.
On the other hand, during autumn and winter when days are shorter with less sunlight exposure due to cloud cover or snowfall etc., your panels would generate significantly less power - around 3.19 kWh/day/kW in autumn and just 1.98 kWh/day/kW in winter.
If you're planning on installing a fixed-panel solar energy system here (meaning one that doesn't move or adjust its angle), it's best to tilt your panels towards south at an angle of approximately 37 degrees for maximum yearly output.
However, there might be certain local factors that could potentially affect how much energy you're able to produce from your solar setup:
1) Snow Coverage: During wintertime especially but also occasionally during late fall or early spring months too; heavy snowfalls may cover up your panels reducing their sunlight exposure & hence their power generation capability.
Preventive Measure: Regularly clearing off accumulated snow from the surface of your panels can help ensure they continue generating as much power as possible even under snowy conditions
2) Cloudy Weather: Pontiac is known for having many cloudy days throughout various parts of the year which can limit direct sunlight reaching onto your panels.
Preventive Measure: There isn't really any effective way to combat this issue, but it's worth noting that solar panels can still generate some power even under cloudy or overcast conditions although at a reduced rate.
3) Tree Shading: If your property is surrounded by tall trees, their shadows could potentially obstruct sunlight from hitting your panels particularly during early morning or late afternoon hours.
Preventive Measure: Trimming back tree branches regularly might be necessary to prevent shading issues and help maximize your system's overall energy production.
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 Pontiac
Seasonal solar PV output for Latitude: 42.6678, Longitude: -83.2917 (Pontiac, 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 Pontiac, United States
To maximize your solar PV system's energy output in Pontiac, United States (Lat/Long 42.6678, -83.2917) 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 Pontiac, 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 Pontiac, 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 | 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.
Calculate solar panel row spacing in Pontiac, 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 Pontiac, 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 Pontiac, United States
Pontiac, United States is located in the state of Michigan and is characterized by a relatively flat topography. The area has an average elevation of around 928 feet above sea level. There are no significant hills or mountains in the immediate vicinity, and the land generally consists of plains with some small lakes and rivers.
As for solar PV installation, large-scale solar farms ideally require flat or gently sloping areas that receive a lot of sunlight throughout the year. In Pontiac's case, any open fields or unused agricultural lands would be suitable for this purpose.
However, it's important to consider that Michigan isn't known for its high levels of sunshine compared to states like Arizona or California. According to US Climate Data, Pontiac gets about 179 sunny days per year on average which is less than the US average of 205 sunny days.
Therefore while technically possible to install large-scale solar PV systems around Pontiac due to its flat terrain, it may not be as efficient as installing them in sunnier locations unless advancements in technology can help overcome these challenges.
In addition to this, such projects should also take into account other factors like local zoning laws and regulations related to renewable energy installations before proceeding.
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.
