During these months, longer days and higher sun angles contribute to increased solar panel efficiency. However, it's worth noting that even during the less productive winter months, solar panels continue to generate a meaningful amount of electricity.
Panel Installation Considerations
For fixed panel installations in Garner, the optimal tilt angle to maximize year-round solar production is 31 degrees facing South. This angle is calculated based on the location's latitude and seasonal solar elevation angles, ensuring the best overall performance throughout the year.
Environmental and Weather Factors
While Garner generally provides favorable conditions for solar energy production, there are a few environmental and weather factors to consider:
- Occasional severe weather events, such as hurricanes or thunderstorms, may temporarily impact solar production.
- Tree cover in some areas could potentially cast shadows on solar panels, reducing their efficiency.
To mitigate these factors, consider the following preventative measures during solar installation:
- Use durable, weather-resistant solar panels and mounting systems designed to withstand high winds and heavy rainfall.
- Conduct a thorough site assessment to identify and address potential shading issues from nearby trees or structures.
- Implement a regular cleaning and maintenance schedule to ensure optimal panel performance.
In conclusion, Garner, North Carolina, presents a highly suitable location for solar PV energy generation. With proper installation and maintenance, solar panels in this area can provide significant energy output throughout the year, particularly during the spring and summer months.

Solar output per kW of installed solar PV by season in Garner
Seasonal solar PV output for Latitude: 35.7113, Longitude: -78.6142 (Garner, 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 31° South in Garner, United States
To maximize your solar PV system's energy output in Garner, United States (Lat/Long 35.7113, -78.6142) throughout the year, you should tilt your panels at an angle of 31° 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 Garner, 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 Garner, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 20° South in Summer | 41° South in Autumn | 51° South in Winter | 28° 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 Garner, United States
