Francesville, Indiana, located in the Northern Temperate Zone, offers a moderate potential for solar energy generation throughout the year. The location's latitude and longitude (40.9853, -86.8795) contribute to varying levels of solar production across different seasons.

Seasonal Solar Production

Solar energy output at this location fluctuates significantly between seasons. Summer proves to be the most productive period, with an average daily output of 6.36 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.48 kWh per day. Autumn sees a considerable decrease in production, with 3.56 kWh per day, while winter experiences the lowest output at 2.31 kWh per day.

Optimal Times for Solar Generation

The most ideal times for solar energy production in Francesville are during the summer months, typically from June to August, when daylight hours are longest and the sun's angle is most favorable. Spring months, particularly April and May, also offer good potential for solar generation. Conversely, winter months from December to February present the greatest challenges due to shorter days and the sun's lower position in the sky.

Panel Installation Considerations

For fixed panel installations in Francesville, the optimal tilt angle to maximize year-round solar production is 35 degrees facing South. This angle helps balance energy capture across seasons, compensating for the sun's changing position throughout the year.

Environmental and Weather Factors

Several factors may impact solar production in Francesville:

1. Snow accumulation in winter can temporarily reduce panel efficiency.
2. Cloudy days, particularly common in autumn and winter, may decrease solar output.

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, using high-efficiency panels and micro-inverters can help maximize production during periods of lower sunlight. Regular cleaning and maintenance of panels, especially after snowfall, can also ensure optimal performance year-round.

While Francesville's location presents some challenges for solar energy production, particularly in winter, the overall potential remains favorable. With proper installation techniques and maintenance, solar PV systems can provide a significant contribution to energy needs throughout the year.

Ideally tilt fixed solar panels 35° South in Francesville, United States

To maximize your solar PV system's energy output in Francesville, United States (Lat/Long 40.9853, -86.8795) throughout the year, you should tilt your panels at an angle of 35° 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 Francesville, 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 Francesville, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° 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	55° 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 Francesville, 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 Francesville, United States.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Francesville, United States

The topography around Francesville, Indiana, United States (located at approximately 40.9853°N, 86.8795°W) is characterized by gently rolling plains and flat agricultural lands. This area is part of the broader Midwestern region known for its relatively level terrain, with only minor variations in elevation. The landscape is predominantly rural, featuring expansive farmlands, scattered woodlots, and occasional streams or small rivers. The region surrounding Francesville is primarily composed of glacial till plains, formed during the last ice age when glaciers retreated and left behind deposits of soil and rock. This geological history has resulted in fertile soils that are well-suited for agriculture, which is a dominant land use in the area. The terrain is generally flat to slightly undulating, with subtle changes in elevation that are barely noticeable to the casual observer.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain in the vicinity of Francesville offers advantages for solar development. Large, open agricultural fields provide ample space for solar arrays without the need for significant land grading or preparation. Areas to the south and southeast of Francesville may be particularly well-suited for solar PV projects. These locations typically receive more direct sunlight throughout the year due to their slightly more southerly position. Additionally, any gently sloping land facing south or southeast would be ideal for maximizing solar exposure. It's important to note that while the topography is generally favorable, other factors such as proximity to electrical infrastructure, local zoning regulations, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar developments. Consultation with local authorities and conducting detailed site assessments would be necessary to identify specific optimal areas for such projects.

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.
