One common question that people ask is: Will trees affect solar panels as they increasingly switch to solar power?
Trees provide the shade that we all need during those hot summer days. Simply put, trees are great for keeping things cool. They can also block the sun in unwanted places, such as on solar panels.
The performance of solar panels is affected by trees casting too much shade (specifically, their efficiency and effectiveness). It’s not good for your system’s overall output!
This article will explore the effects of trees on solar panels and how they can be improved to achieve better performance.
SHADING AND SOLAR PANEL PERFORMANCE
Solar panels are most efficient when they receive unobstructed, direct sunlight. Any shading by trees could reduce their ability to produce maximum energy.
Even partial shading of a small part of your solar panels can affect the efficiency of your system. Why? Solar panels are typically interconnected (i.e., connected via complex wiring).
When one panel is more efficient than another, the efficiency of all surrounding panels will either increase or decrease. This will eventually impact your system’s energy output.
Explore some of the factors that affect your panel’s shade.
TREE POSITIONING & SOLAR PANEL ORDERING
The height and position of the trees surrounding your solar panels will directly impact how much shade you get and, therefore, how efficient your solar panel system becomes.
As an example, trees located on the east and west sides of your system will cast shadows at specific times (and critical) of the day when the sun is rising or setting. Trees on the southern end of your solar system will provide more consistent shading throughout the day when the sun is at its highest and slowly moving across the sky.
Before installing solar panels, you should assess the trees that surround your home or office, specifically their height and how close they are to your system. You’ll be able to determine better shading patterns and how much energy can be produced without destroying any trees.
Seasonal Variations
Seasonal changes are another factor to consider.
Trees can shade panels more or less depending on the season. Your panels will likely receive less shade during the winter when the sun is lower in the sky.
When determining the unique shade potential of your trees, it’s important to consider seasonal patterns as well as local climate characteristics. You can then decide if trees are having an impact on the performance of your solar panels.
TREE TRIMMING AND PRUNING
You can eliminate any shade issues by pruning and trimming your trees. Trim any branches that are casting shadows directly on your solar panels. This will minimize any sunlight obstruction.
You should always consult a professional arborist before you do any work on your trees. Better yet, you can hire professionals to do the work for you. It is important to ensure that your trees are pruned safely and properly.
Design and placement of solar panels
It is important to carefully consider the placement and design of your panels, as these factors can reduce shading effects. Optimizing the panel’s orientation and tilt angle, for example, can block (or partially block) tree shading.
Incorporating microinverters or power optimizers in each solar panel also allows them to work independently. You can reduce the energy loss caused by shade.
Consider trees before selecting an installation site
It’s important to consider the trees around your solar installation before choosing a location. You can choose the best place by considering the future growth of trees.
- Minimizing shading concerns
- Maximizing solar energy production
Note. Although trees can have an impact on solar panel performance, it is important to keep in mind their environmental benefits. They contribute to cleaner air because they reduce carbon dioxide. Please think twice before you remove them completely from your property.
