Rumford, Rhode Island, United States is a location with moderate potential for solar PV energy generation, experiencing significant seasonal variations in electricity production throughout the year. Located in the Northern Temperate Zone, this area demonstrates the typical pattern of higher solar energy production in summer months with notable decreases during winter.

Seasonal Solar Production

The solar energy production at this location varies considerably across the four seasons. Summer represents the peak production period, generating an average of 6.10kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind with 5.73kWh/day per installed kilowatt. Production drops significantly in autumn to 3.59kWh/day, while winter experiences the lowest output at just 2.09kWh/day per kilowatt of installed capacity.

This seasonal pattern creates a roughly 3:1 ratio between the best and worst production months, which is typical for locations in the northern United States. The substantial difference between summer and winter production means that system sizing needs to account for these seasonal variations.

Optimal Panel Installation

For fixed panel installations in Rumford, the ideal tilt angle to maximize year-round solar production is 36 degrees facing South. This angle has been calculated by analyzing daily solar elevation angles at this specific latitude, weighted according to the daily PV potential, and accounting for Earth's elliptical orbit.

This fixed tilt represents a compromise that balances summer and winter production. While a flatter angle might capture more energy during summer months, the steeper 36-degree angle helps maximize the lower winter sun and improves year-round performance.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Rumford:

• Snow accumulation during winter months can temporarily reduce output if panels become covered. This is particularly relevant given the already lower winter production rates.
• The New England region experiences numerous cloudy days throughout the year, which can reduce overall efficiency compared to sunnier regions.
• Coastal influences from nearby Narragansett Bay may increase humidity and fog occurrence, potentially reducing clarity of sunlight reaching panels.

To mitigate these factors, several preventative measures can be implemented:

• Installing panels at the recommended 36-degree tilt not only optimizes production but also helps shed snow more effectively than flatter installations.
• Using microinverters or power optimizers can minimize the impact of partial shading from nearby trees or structures.
• Regular cleaning and maintenance, particularly after winter storms, will ensure maximum production.
• Selecting high-efficiency panels that perform better in diffuse light conditions can help compensate for cloudy New England days.

Overall, while Rumford doesn't offer ideal solar conditions year-round, proper system design with the recommended tilt angle and appropriate preventative measures can still provide meaningful energy production, particularly during the spring and summer months when output is substantially higher.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Rumford, Rhode Island

Seasonal solar PV output for Latitude: 41.8417, Longitude: -71.3516 (Rumford, Rhode Island, 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 Rumford, Rhode Island, United States

To maximize your solar PV system's energy output in Rumford, Rhode Island, United States (Lat/Long 41.8417, -71.3516) 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 Rumford, Rhode Island, 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 Rumford, Rhode Island, 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
25° South in Summer	46° 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.

   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 Rumford, Rhode Island, United States

Topography of Rumford, Rhode Island

Rumford is located in the eastern part of Rhode Island, specifically in the city of East Providence. The terrain in this area is characterized by gently rolling hills with modest elevation changes. The topography gradually slopes towards the Seekonk River which forms part of the eastern boundary of East Providence. The landscape has been significantly shaped by glacial activity from the last ice age, resulting in a mix of small hills, shallow valleys, and some wetland areas. The elevation in Rumford generally ranges between 30 to 100 feet (9 to 30 meters) above sea level, making it relatively flat compared to the more rugged terrain found in western Rhode Island. This area is part of the coastal lowlands that characterize much of eastern Rhode Island, with a gradual transition to the slightly more elevated Piedmont region to the west.

Suitable Areas for Solar PV Development

When considering large-scale solar photovoltaic (PV) development near Rumford, several factors related to topography come into play. The relatively flat terrain in many parts of East Providence and neighboring communities provides favorable conditions for solar installations, as it minimizes the need for extensive grading and site preparation. Former industrial areas along the Seekonk River offer potential for solar development. These brownfield sites, which may have limited options for redevelopment, present opportunities for solar installations without disrupting natural habitats or agricultural land. The gently sloping south-facing hillsides found throughout the area would receive optimal sun exposure, making them particularly suitable for solar PV arrays. Open spaces in neighboring communities like Seekonk and Rehoboth (Massachusetts) feature larger tracts of land with favorable topography for utility-scale solar. These areas have sufficient flat or gently rolling terrain that could accommodate extensive solar installations while minimizing environmental impact. The relatively low-lying nature of the region does present some challenges, including potential flooding in areas closest to waterways and wetlands. Solar developers would need to focus on slightly elevated areas that provide natural drainage while still offering the flat, open spaces ideal for large solar arrays. When considering specific locations, areas north and west of Rumford that feature cleared land with minimal tree cover would be most appropriate. The combination of gentle slopes, adequate drainage, and open exposure makes these locations particularly well-suited for capturing solar energy while minimizing installation challenges related to the local topography.
