Warren, Rhode Island, located in the Northern Temperate Zone at coordinates 41.7241, -71.2657, presents a moderately favorable location for solar PV energy generation throughout the year. The seasonal variations in electricity output highlight both opportunities and challenges for solar energy production in this area.

Seasonal Performance

Summer stands out as the most productive season for solar energy in Warren, with an impressive daily output of 6.12 kWh per kW of installed solar capacity. This high performance is due to longer daylight hours and more direct sunlight during the summer months. Spring follows closely behind summer in terms of solar productivity, generating 5.77 kWh per day for each kW of installed capacity. The increasing daylight hours and generally clearer skies contribute to this strong performance. Autumn sees a significant drop in solar output, with 3.65 kWh per day per kW of installed capacity. This decrease is attributed to shorter days and the sun's lower position in the sky. Winter presents the greatest challenge for solar energy production in Warren, with output falling to 2.15 kWh per day per kW of installed capacity. The combination of shorter days, lower sun angle, and increased cloud cover contributes to this reduced performance.

Optimal Panel Placement

To maximize year-round solar energy production in Warren, fixed solar panels should be tilted at a 36-degree angle facing south. This orientation helps capture the most sunlight throughout the year, balancing the varying sun angles across seasons.

Environmental Considerations

While Warren's location is generally suitable for solar energy production, there are some environmental factors to consider: 1. Snow accumulation in winter can temporarily reduce panel efficiency. 2. Coastal location may expose panels to salt spray, potentially affecting performance over time. To mitigate these issues, consider the following preventative measures: • Install panels at a steeper angle to encourage snow sliding off • Use corrosion-resistant materials and regular cleaning to combat salt spray effects • Implement a routine maintenance schedule to ensure optimal performance Overall, Warren, Rhode Island offers a good location for solar PV energy generation, with strong performance in summer and spring offsetting the challenges faced during autumn and winter months.

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

Seasonal solar PV output for Latitude: 41.7241, Longitude: -71.2657 (Warren, 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 Warren, Rhode Island, United States

To maximize your solar PV system's energy output in Warren, Rhode Island, United States (Lat/Long 41.7241, -71.2657) 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 Warren, 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 Warren, 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.

Calculate solar panel row spacing in Warren, Rhode Island, 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 Warren, Rhode Island, 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 Warren, Rhode Island, United States

The topography around Warren, Rhode Island, located at latitude 41.7241 and longitude -71.2657, is characterized by a mix of coastal lowlands and gently rolling hills. This area is situated along the eastern shore of Narragansett Bay, with the Warren River flowing through the town. The landscape is generally flat to slightly undulating, with elevations ranging from sea level near the coast to about 50-100 feet above sea level in the inland areas. The coastal regions of Warren feature salt marshes, tidal flats, and small beaches, while the inland areas consist of a combination of residential neighborhoods, farmland, and patches of forest. The terrain is primarily composed of glacial deposits, including sand, gravel, and clay, left behind by retreating ice sheets during the last ice age.

Potential Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. Ideal locations for solar farms typically require large, open spaces with minimal shading and relatively flat terrain. Based on these criteria, some potential areas near Warren that might be suitable for solar PV development include: Former agricultural lands or fallow fields in the surrounding towns of Barrington, Bristol, and Swansea (MA) could provide ample space for solar arrays. These areas often have the advantage of being relatively flat and free from obstructions that could cast shadows on the panels. Brownfield sites or former industrial areas in nearby communities like East Providence or Fall River (MA) might also be suitable for solar development. These locations often have the necessary infrastructure in place and are already zoned for industrial use, potentially simplifying the permitting process. It's important to note that while the topography around Warren is generally favorable for solar PV installations, other factors such as local zoning regulations, environmental considerations, and grid connection availability would need to be carefully evaluated before determining the feasibility of any large-scale solar project in the area.

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.
