Solon, Maine, located in the Northern Temperate Zone, presents a mixed scenario for year-round solar energy generation via photovoltaic (PV) systems. The location's seasonal variations in solar output highlight both opportunities and challenges for solar power production.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.76 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.36 kWh/day. These seasons offer excellent conditions for solar energy production, with long daylight hours and generally clearer skies.

Autumn sees a significant drop in output, producing 3.13 kWh/day. Winter experiences the lowest production at 1.95 kWh/day, due to shorter days, lower sun angles, and potentially more overcast conditions.

Optimal Panel Positioning

For fixed panel installations in Solon, the ideal tilt angle to maximize year-round production is 39 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental and Weather Considerations

Several factors could impact solar production in Solon:

• Snow accumulation in winter can significantly reduce panel efficiency
• Frequent overcast days, especially in fall and winter, may limit solar exposure
• Potential for ice storms could damage equipment if not properly protected

To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off, use high-quality, weather-resistant equipment, and implement regular maintenance schedules. Snow removal systems or manual clearing may be necessary during heavy snowfall periods.

Conclusion

While Solon's location presents challenges, particularly in winter, it still offers substantial potential for solar energy generation. The strong performance in spring and summer can help offset the reduced output in fall and winter. With proper planning and mitigation strategies, a solar PV system in Solon can be a viable source of renewable energy year-round.

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

Seasonal solar PV output for Latitude: 44.9495, Longitude: -69.8584 (Solon, 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 39° South in Solon, United States

To maximize your solar PV system's energy output in Solon, United States (Lat/Long 44.9495, -69.8584) throughout the year, you should tilt your panels at an angle of 39° 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 Solon, 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 Solon, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
29° South in Summer	49° South in Autumn	59° South in Winter	38° 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 Solon, 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 Solon, 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 Solon, United States

The topography around Solon, Maine, located at approximately 44.9495°N and 69.8584°W, is characterized by a diverse landscape typical of central Maine. This area is part of the Appalachian Mountain region, featuring a mix of rolling hills, small mountains, and river valleys. The terrain is generally undulating, with elevations ranging from around 400 to 1,000 feet above sea level. The region surrounding Solon is heavily forested, with a mix of deciduous and coniferous trees covering much of the land. The Kennebec River flows through the area, carving a scenic valley and creating some flatter areas along its banks. Numerous smaller streams and brooks crisscross the landscape, contributing to the region's varied topography.

Potential Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Solon, several factors come into play. Ideal areas would have relatively flat or gently sloping terrain, good sun exposure, and minimal shading from surrounding hills or forests. Some of the most suitable areas for solar PV development in the vicinity of Solon might include: 1. Open agricultural fields: The region has some cleared farmland that could potentially be repurposed for solar installations. These areas often provide the necessary space and sun exposure for large-scale projects. 2. Hilltops and ridges: While some of the higher elevations in the area may be too steep or forested, there are likely some hilltops or ridge areas with gentler slopes that could accommodate solar arrays. These locations often benefit from increased sun exposure and reduced shading. 3. Reclaimed or brownfield sites: Any former industrial or commercial sites in the broader region that have been cleared of structures could be prime candidates for solar development, as they often offer large, open spaces with existing infrastructure connections. 4. Areas along the Kennebec River: Some of the flatter areas along the river valley, particularly those that are not prone to flooding, could potentially be suitable for solar installations. It's important to note that while these areas may have favorable topography for solar PV, other factors such as local zoning regulations, environmental considerations, and grid connection availability would also need to be taken into account when planning any large-scale solar projects in the region.

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.
