Solar PV Analysis of Ashland, United States
Ashland, Massachusetts is a decent location for producing solar energy throughout the year. However, the effectiveness varies with each season due to changes in sunlight hours and intensity.
During summer and spring, you can expect higher electricity output of around 5.75kWh/day and 5.42kWh/day respectively from every kilowatt of installed solar power because these seasons have longer days and more direct sunlight. Autumn produces a moderate amount of energy at about 3.35kWh/day per kilowatt due to shorter daylight hours compared to summer and spring while winter has the lowest production at approximately 2.01 kWh/day per kilowatt because it has the shortest days with least intense sunlight.
To maximize your year-round solar power generation in Ashland, it's recommended that your solar panels are tilted at an angle of 37 degrees facing south. This angle allows your panels to capture as much sunlight as possible throughout different times of the day and during various seasons.
However, there could be local factors that may hinder optimal production of solar energy in Ashland such as heavy snowfall or shading from trees or buildings which can block direct sunlight from reaching the panels especially during winter months when snowfall is common in this region.
To overcome these challenges:
1) You can install a snow guard on your panels to prevent accumulation which will keep them clear for maximum exposure to sun rays.
2) If shading is an issue due to tall trees or structures nearby, consider trimming back tree branches or selecting a installation site that receives full sun exposure.
3) Regular cleaning and maintenance should also be carried out on your panels since dirt or bird droppings can also limit their efficiency by blocking light absorption.
In summary, while there are periods where less energy might be generated especially during autumn and winter months due largely to reduced daylight hours; with proper panel positioning (tilted at an angle of 37 degrees facing south), regular maintenance and strategic installation site selection, Ashland, Massachusetts can still be a good location for year-round solar energy production.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 4253 locations across the United States. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Ashland
Seasonal solar PV output for Latitude: 42.2546, Longitude: -71.4564 (Ashland, 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 37° South in Ashland, United States
To maximize your solar PV system's energy output in Ashland, United States (Lat/Long 42.2546, -71.4564) throughout the year, you should tilt your panels at an angle of 37° 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 Ashland, 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 Ashland, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° 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 | 47° South in Autumn | 57° 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 Ashland, 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 Ashland, United States.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Ashland, United States
The coordinates provided point to Ashland, Massachusetts, United States. This area is characterized by a relatively flat topography with some gently rolling hills. It's part of the Eastern New England Upland, an area known for its mixed forest and woodland terrain.
For large-scale solar photovoltaic (PV) installations, areas with high levels of sunlight and flat or gently sloping lands are ideal. In this context, open fields or unused industrial sites in and around Ashland could be potential locations for solar PV systems.
However, it's important to note that the feasibility of large-scale solar PV also depends on factors like local climate conditions (annual sunshine hours), land use regulations, proximity to power grids for energy transmission and economic considerations such as cost of land and installation.
As per National Renewable Energy Laboratory data, Massachusetts has moderate solar potential compared to other states in the U.S., but government incentives can make solar projects economically feasible.
In general terms without considering specific parcels of land or regulatory constraints within Ashland itself or nearby towns like Framingham or Holliston might provide suitable locations given their similar topographical characteristics.
A detailed site-specific assessment would be necessary to identify most suitable spots for large scale Solar PV installations.
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.
