Damascus, Oregon, in the United States, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar potential.

Seasonal Solar Production

Summer stands out as the most productive season, with an impressive daily output of 7.12 kWh per kW of installed solar capacity. This makes it an ideal time for maximizing solar energy generation. Spring follows as the second-best season, yielding 5.46 kWh/day per kW.

However, the colder months see a dramatic decrease in solar production. Autumn generates a modest 2.90 kWh/day per kW, while winter experiences a significant drop to just 1.36 kWh/day per kW. This stark contrast highlights the challenges of relying solely on solar power year-round in Damascus.

Optimal Panel Installation

To maximize year-round solar production, fixed panels should be installed at a 37-degree angle facing south. This tilt helps optimize energy capture across all seasons, balancing the high summer sun with the lower winter sun angle.

Environmental Considerations

Several environmental factors can impact solar production in Damascus:

• Cloud cover: The Pacific Northwest is known for its cloudy weather, especially during fall and winter months, which can significantly reduce solar output.
• Rain: Frequent rainfall in the region can decrease panel efficiency, though it also helps keep panels clean.

To mitigate these challenges, consider installing high-efficiency panels that perform well in low-light conditions. Additionally, implementing a solar tracking system can help maximize energy capture during limited sunlight hours.

In conclusion, while Damascus offers excellent solar potential during summer and spring, the significant drop in production during fall and winter means that a hybrid energy solution or energy storage system might be necessary for year-round reliability.

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 Damascus

Seasonal solar PV output for Latitude: 45.4145, Longitude: -122.4616 (Damascus, 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 Damascus, United States

To maximize your solar PV system's energy output in Damascus, United States (Lat/Long 45.4145, -122.4616) 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 Damascus, 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 Damascus, 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
29° South in Summer	48° South in Autumn	60° South in Winter	38° 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 Damascus, 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 Damascus, 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 Damascus, United States

Damascus, United States, located at latitude 45.4145 and longitude -122.4616, is situated in the northwestern part of Oregon. The topography surrounding this area is characterized by a diverse landscape that includes both flat and hilly terrain. To the west of Damascus, the land is relatively flat, with gentle slopes and rolling hills. This area is part of the Willamette Valley, a fertile region known for its agricultural productivity. The valley floor is composed of rich alluvial soil deposited by ancient floods, creating an ideal environment for farming. As you move eastward from Damascus, the terrain becomes more varied and elevated. The city itself sits at the foot of the Cascade Mountain Range, which runs north to south along the western edge of North America. This proximity to the mountains results in a gradual increase in elevation as you travel east, with the landscape becoming more rugged and forested.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby Damascus that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal location for solar PV would have ample sunlight exposure, relatively flat terrain, and minimal shading from trees or other obstacles. The areas to the west of Damascus, within the Willamette Valley, offer the most promising potential for large-scale solar PV projects. The relatively flat terrain and open spaces provide excellent conditions for solar panel installation. These areas receive good sunlight exposure throughout the year, although the region does experience cloudy and rainy weather, particularly during the winter months. It's worth noting that while the valley areas are suitable for solar PV, careful consideration must be given to preserving valuable agricultural land. Balancing the need for renewable energy with the importance of food production is a crucial factor in site selection. The more mountainous areas to the east of Damascus, while offering some potential for solar energy, are generally less ideal for large-scale installations due to their uneven terrain, increased forest cover, and potential shading issues. However, smaller-scale solar projects might still be feasible on south-facing slopes or in cleared areas within these regions. In conclusion, the topography around Damascus offers a mix of landscapes, from the flat Willamette Valley to the west to the rising foothills of the Cascade Range to the east. For large-scale solar PV installations, the flatter areas to the west present the most suitable conditions, provided that land use considerations are carefully balanced.

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]
