Solar PV Analysis of Lebanon, United States
Lebanon, New Hampshire is a moderately good location for solar energy production year-round. The amount of electricity you can generate from solar panels depends on the season. In the summer and spring, when there's more sunlight, you can expect to generate around 5.70kWh/day and 5.15kWh/day per kW of installed solar respectively - these are the best times for generating solar power in Lebanon.
During autumn and winter, however, output drops due to fewer daylight hours and less intense sunlight; expect about 3.05kWh/day in the fall and only about 1.73kWh/day in winter per kW of installed solar.
If you're setting up fixed panel installations here, it would be ideal to tilt your panels at an angle of 38 degrees facing south to get maximum sun exposure throughout the year.
As far as potential obstacles go, Lebanon's weather could pose some challenges for optimal solar production - especially during winter months when snow cover might obstruct panels or reduce their efficiency by reflecting sunlight away instead of letting it get absorbed into the cells. This problem can be mitigated by installing mechanisms that clear off snow automatically or manually clearing it yourself.
Additionally, overcast days common in New England could also lower energy output since clouds block direct sunlight from reaching your panels – but this doesn't mean they stop producing entirely; even diffused light through clouds will still generate some power albeit at a reduced rate compared to full sun conditions.
To ensure greater energy production despite these factors: make sure your installation site is free from shade (especially during peak sunshine hours), consider using higher-efficiency modules that perform better under low light conditions or even bifacial modules that can capture reflected light from snow-covered ground surfaces onto their rear side for extra yield.
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 Lebanon
Seasonal solar PV output for Latitude: 43.6444, Longitude: -72.2455 (Lebanon, 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 38° South in Lebanon, United States
To maximize your solar PV system's energy output in Lebanon, United States (Lat/Long 43.6444, -72.2455) throughout the year, you should tilt your panels at an angle of 38° 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 Lebanon, 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 Lebanon, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 48° South in Autumn | 58° South in Winter | 37° 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 Lebanon, 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 Lebanon, 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 Lebanon, United States
Lebanon, United States is located in the state of New Hampshire. The topography around Lebanon consists mostly of rolling hills and valleys as part of the Appalachian Mountain range. There are also several rivers and lakes in the area.
As for solar PV potential, flat or gently sloping areas would be most suited for large-scale solar installations. These could potentially be found in some valley regions or on cleared land where there is minimal tree cover to obstruct sunlight.
However, considering that Lebanon is at a relatively high latitude (43.6444), it receives less sunlight than locations closer to the equator. This doesn't mean solar power isn't viable here; it just means that more panels might be needed to generate an equivalent amount of power compared to sunnier places.
Also, local factors such as weather patterns (cloud cover, snowfall etc.) can significantly impact solar energy production so these should also be considered when planning large-scale installations.
Finally, any plans for large scale solar PV projects must take into account environmental considerations and local regulations regarding land use and construction permits.
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.
