Elnora, Indiana, located in the Northern Temperate Zone, presents a moderate opportunity for solar energy generation throughout the year. The location's solar potential varies significantly across seasons, with peak production occurring during the summer months.

Seasonal Solar Output

Solar panel efficiency in Elnora fluctuates considerably throughout the year. Summer stands out as the most productive season, with an average daily output of 6.44 kWh per kW of installed solar capacity. Spring follows closely, generating 5.47 kWh/day. Autumn sees a noticeable decrease to 3.91 kWh/day, while winter experiences the lowest output at 2.23 kWh/day.

Optimal Installation Angle

To maximize year-round solar energy production in Elnora, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's latitude.

Best Times for Solar Generation

The most ideal period for solar energy production in Elnora spans from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. Summer solstice, typically around June 21, marks the peak of solar potential in this region.

Environmental and Weather Factors

While Elnora's location is generally favorable for solar energy, there are some environmental and weather factors that could impact solar production:

• Snow accumulation in winter months can temporarily reduce panel efficiency
• Cloudy days, particularly common in late fall and winter, may decrease solar output

Preventative Measures

To mitigate these factors and ensure optimal energy production, consider implementing the following measures when installing solar panels in Elnora:

1. Use snow-shedding panel designs or install panels at a steeper angle to promote snow sliding off
2. Incorporate a robust cleaning and maintenance schedule, especially during winter months
3. Consider microinverters or power optimizers to minimize the impact of partial shading on cloudy days
4. Install high-efficiency panels that perform well in low-light conditions

By addressing these local factors and implementing appropriate preventative measures, solar energy systems in Elnora can achieve higher efficiency and more consistent output throughout the year.

Solar output per kW of installed solar PV by season in Elnora

Seasonal solar PV output for Latitude: 38.8746, Longitude: -87.0812 (Elnora, 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 34° South in Elnora, United States

To maximize your solar PV system's energy output in Elnora, United States (Lat/Long 38.8746, -87.0812) throughout the year, you should tilt your panels at an angle of 34° 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 Elnora, 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 Elnora, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
23° South in Summer	43° South in Autumn	54° South in Winter	32° 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 Elnora, 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 Elnora, 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 Elnora, United States

The topography around Elnora, United States, located at latitude 38.8746 and longitude -87.0812, is characterized by gently rolling hills and broad, flat plains typical of the Midwestern United States. This area, situated in southwestern Indiana, is part of the Interior Low Plateaus region, which features a mix of agricultural land, forests, and scattered waterways. The landscape surrounding Elnora is primarily composed of fertile farmland interspersed with patches of deciduous forest. The terrain is relatively flat with subtle elevation changes, rarely exceeding 100 feet in variation. This gentle topography is a result of glacial activity during the last ice age, which smoothed out much of the region's surface. Several small streams and creeks wind through the area, eventually feeding into larger rivers such as the White River, which flows about 10 miles to the north of Elnora. These waterways have carved shallow valleys in the landscape over time, creating slight undulations in the otherwise level terrain.

Suitability for Large-Scale Solar PV

The areas most suited for large-scale solar photovoltaic (PV) installations near Elnora would be the expansive, open farmlands that dominate the region. These flat, unobstructed spaces provide ideal conditions for solar panel arrays, offering maximum exposure to sunlight throughout the day. Specifically, the agricultural fields to the south and east of Elnora present the best opportunities for solar PV development. These areas benefit from minimal shading from trees or buildings and have easy access to existing road infrastructure, which is crucial for construction and maintenance of solar facilities. The gently sloping terrain in some parts of the region could also be advantageous for solar installations, as a slight tilt towards the south can optimize solar panel efficiency. However, care should be taken to avoid low-lying areas near streams or in flood-prone zones, as these could pose risks to the equipment. It's worth noting that while the topography is suitable for solar PV, developers would need to consider other factors such as local zoning regulations, grid connection capabilities, and the impact on agricultural production when planning large-scale solar projects in this predominantly rural area.
