Painesville, Ohio, located in the Northern Temperate Zone, offers a mixed potential for solar energy generation throughout the year. The city's location at latitude 41.7245 and longitude -81.2457 experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar PV systems.

Seasonal Solar Performance

Solar energy production in Painesville varies greatly across the seasons. Summer stands out as the most productive period, with an impressive 6.00 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.40 kWh/day. However, there's a sharp decline in output during autumn (3.29 kWh/day) and winter (1.79 kWh/day).

The stark contrast between summer and winter production highlights the challenges of relying solely on solar power in this region year-round. Nevertheless, the strong performance during spring and summer months makes solar a viable supplementary energy source for much of the year.

Optimal Panel Placement

To maximize year-round solar energy production in Painesville, fixed solar panels should be installed at a tilt angle of 36 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, considering the city's latitude and seasonal sun positions.

Environmental Factors and Mitigation

Several environmental factors in Painesville can impact solar energy production:

1. Snow accumulation in winter, which can cover panels and reduce output
2. Frequent cloud cover, particularly in late autumn and winter

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, using high-efficiency panels and incorporating a robust cleaning schedule can help maintain optimal performance despite challenging weather conditions.

In conclusion, while Painesville's location presents some challenges for year-round solar energy production, proper panel placement and mitigation strategies can still make solar PV a valuable component of the local energy mix, especially during the more productive spring and summer months.

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

Seasonal solar PV output for Latitude: 41.7245, Longitude: -81.2457 (Painesville, 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 36° South in Painesville, United States

To maximize your solar PV system's energy output in Painesville, United States (Lat/Long 41.7245, -81.2457) throughout the year, you should tilt your panels at an angle of 36° 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 Painesville, 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 Painesville, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
26° South in Summer	45° South in Autumn	56° South in Winter	35° 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 Painesville, 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 Painesville, 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 Painesville, United States

The topography around Painesville, United States, located at latitude 41.7245 and longitude -81.2457, is characterized by gently rolling terrain with a mix of flat areas and low hills. This region, situated in northeastern Ohio near the southern shore of Lake Erie, features a landscape shaped by glacial activity thousands of years ago. The area surrounding Painesville is part of the Lake Plains region, which is generally flat to slightly undulating. As you move inland from the lake, the terrain gradually rises, forming subtle hills and shallow valleys. The Grand River, a major waterway in the region, has carved a scenic valley through the landscape, creating some areas of steeper slopes and bluffs near its banks.

Suitable Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Painesville, several factors come into play. The most suitable areas would be those with relatively flat terrain, good sun exposure, and minimal shading from natural or man-made structures. The agricultural lands south and east of Painesville offer promising potential for solar PV development. These areas typically feature expansive, open fields with minimal tree cover, providing excellent sun exposure throughout the day. The gently rolling nature of the terrain in this region would not significantly impact solar panel efficiency, as modern mounting systems can easily accommodate slight variations in elevation. Another potentially suitable area for large-scale solar PV installations would be the more level portions of former industrial sites or brownfields in the region. These locations often have the advantage of being already developed, with existing infrastructure and minimal environmental impact concerns. It's worth noting that while the immediate vicinity of the Grand River Valley may offer some attractive flat areas, care should be taken to avoid flood-prone zones and areas of ecological significance. Additionally, any solar development would need to consider local zoning regulations, grid connection capabilities, and potential impacts on neighboring communities. Overall, the topography around Painesville presents several opportunities for large-scale solar PV development, particularly in the open agricultural areas and repurposed industrial sites that offer the right combination of flat terrain and unobstructed sun exposure.

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?
