Andover, New Jersey, located in the Northern Temperate Zone, presents a varied landscape for solar energy production throughout the year. This location experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

Summer stands out as the prime season for solar energy generation in Andover, with an impressive daily output of 6.05 kWh per kW of installed solar capacity. Spring follows closely behind, yielding 5.47 kWh/day. However, the colder months see a substantial drop in production, with autumn generating 3.54 kWh/day and winter plummeting to a mere 2.18 kWh/day.

This stark contrast between seasons underscores the importance of efficient system design and sizing to ensure adequate year-round energy production. While summer and spring offer abundant sunlight, winter's reduced daylight hours and lower sun angle significantly impact solar efficiency.

Optimal Panel Positioning

To maximize year-round solar energy production in Andover, fixed solar panels should be tilted at a 36-degree angle facing south. This optimal angle takes into account the location's latitude and seasonal sun positions, striking a balance between summer and winter solar exposure.

Environmental Considerations

Andover's location in the Northern Temperate Zone brings certain environmental factors that can affect solar production:

• Snow accumulation in winter can temporarily reduce panel efficiency
• Deciduous trees may cast shadows on panels, especially in fall and winter

To mitigate these issues, consider installing panels at a steeper angle to encourage snow slide-off and conduct regular tree maintenance to minimize shading. Additionally, using microinverters or power optimizers can help maintain system efficiency even when some panels are partially shaded.

Despite these challenges, Andover's location still offers substantial potential for solar energy production, particularly from late spring through early fall. With proper system design and maintenance, solar PV can be a viable and eco-friendly energy option for residents and businesses in this New Jersey town.

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 Andover, New Jersey

Seasonal solar PV output for Latitude: 40.9859, Longitude: -74.7421 (Andover, New Jersey, 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 36° South in Andover, New Jersey, United States

To maximize your solar PV system's energy output in Andover, New Jersey, United States (Lat/Long 40.9859, -74.7421) throughout the year, you should tilt your panels at an angle of 36° 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 Andover, New Jersey, 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 Andover, New Jersey, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
25° South in Summer	45° South in Autumn	56° South in Winter	34° 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.
