Solar PV Analysis of Westminster, United States
Westminster, Maryland, located in the United States with coordinates 39.5693 latitude and -76.9869 longitude, showcases a promising potential for solar photovoltaic (PV) energy generation throughout the year. The average kilowatt-hour (kWh) produced per day for each kilowatt (kW) of installed solar varies by season: summer offers an impressive 6.43 kWh/day, followed by spring at 5.64 kWh/day, autumn at 3.77 kWh/day, and winter at a lower but still substantial 2.26 kWh/day per kW of installed solar.
The optimal tilt angle for fixed panel installations in this area is towards south with an inclination of 34 degrees to maximize sunlight capture throughout the year.
However, certain environmental factors could impact energy production from these systems in Westminster; primarily weather-related issues such as heavy rainfall or snowfall which can decrease available sunlight and therefore reduce power output from the panels.
To mitigate these potential impediments to solar production, it's essential to consider preventative measures during installation like ensuring adequate drainage around the installation site to prevent water accumulation that could damage panels or cause shading effects. Additionally, planning for regular maintenance including snow removal during winter months will help maintain optimal performance levels year-round despite environmental challenges.
In summary, while Westminster's location presents some seasonal variations and weather-related challenges concerning solar power generation capacity; its overall potential remains high due to favorable average daily energy yields across all seasons when properly managed and maintained.
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 Westminster
Seasonal solar PV output for Latitude: 39.5693, Longitude: -76.9869 (Westminster, 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 34° South in Westminster, United States
To maximize your solar PV system's energy output in Westminster, United States (Lat/Long 39.5693, -76.9869) throughout the year, you should tilt your panels at an angle of 34° 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 Westminster, 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 Westminster, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 23° South in Summer | 44° South in Autumn | 55° South in Winter | 32° 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 Westminster, 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 Westminster, 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 Westminster, United States
The topography around Westminster, United States is mostly flat. The nearby areas that would be most suitable for large-scale solar PV installations are open fields and agricultural land that have a southward facing slope to maximize the amount of sunlight they receive. These areas should also have access to existing infrastructure such as roads and power lines, so that the energy produced can be easily transported to where it is needed. Additionally, these sites should not be too close to residential areas or other sensitive locations in order to minimize any potential environmental impacts.
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.
