If you’re considering solar energy, but your home is surrounded by trees, you may be wondering, “will solar panels work with lots of trees?” While yes, trees do impact solar panel performance, that doesn’t mean going solar is impossible. With smart system design, strategic trimming, and the right technology, solar panels and trees can coexist on your property. In this blog post, we’re breaking down how trees and shading impact solar panel performance and how you can optimize your system without cutting down your entire backyard.
How Do Trees Impact Solar Panel Performance?
Solar panels are most efficient when they receive direct, unobstructed sunlight, especially during peak sun hours. Typically, the 4+ hours around the middle of the day is when the sun is strongest and your solar system is generating the most energy.
When trees or other buildings cast shadows on your solar panels, it reduces the amount of direct sunlight that hits the panels. This leads to lower energy output.
Most solar systems are made up of interconnected solar panels, meaning if one panel’s output drops due to shading, it can impact the performance of the entire solar array.
Even a small amount of shade can create problems. Since most solar systems are made up of interconnected panels, if one panel’s output drops due to shade, it can affect the performance of the entire array.
Think of it this way – the solar panels in an array work together as a team!
Just because you have trees and some shading, that doesn’t mean solar is totally ruled out for you. In most cases, you can remove a few branches or trim your trees in order to give your solar panels the best access to direct sunlight.
Here at Blu Solar, we can run a sunlight analysis of your home to see how much power a solar system can provide you. This is helpful if you have trees or another home or building that shades your roof and you’re unsure if your home will get enough sunlight to make it worthwhile.
Some homeowners who get solar are not able to offset their entire electricity usage, but can still supplement a good amount of power for their home.
Solar Panels and Trees: Can They Coexist?
Yes, you can absolutely still have solar panels, even if you have a lot of trees in your backyard. You may just need to make some strategic adjustments to ensure your solar system works as efficiently as possible.
Before installing solar panels, a professional solar installer will evaluate your roof and property to determine how much sun exposure you have. Using specialized tools, they’ll measure how trees affect the sunlight exposure of your home across different times of day. You might find that your home receives enough sunlight during peak hours, even if trees cause partial shading at other times.
Should I Cut Down Trees for Solar Panels?
This question depends on the trees, their placement, and how much shading they cause on your roof. In many cases, trimming a few tree limbs or thinning out a canopy is enough to restore adequate sun exposure. Removing full trees is typically a last resort that is considered only if the tree is causing deep, constant shade over much of the solar array.
At Blu Solar, we offer tree trimming and removal services if you need this done. We have also partnered with a non-profit organization to plant new trees on your behalf so you can keep your sustainable lifestyle in balance and reap the environmental benefits provided by having trees on your property.
Tips for Managing Trees and Solar Panels
Assess Your Tree Shade Impact
When it comes to solar panels and tree shade effects, it’s important to assess the trees on your property and the shadows they cast in order to optimize your sunlight absorption and electricity generation. The more shade, the lower the system’s performance.
During the solar panel design process, your solar panel professionals will assess your roof or installation area for shading. Using tools like solar pathfinders or shading analysis software, they’ll determine how much shade your trees create during the day, which will help determine what type of mounting system is needed and if any trimming or tree removal is necessary.
Consistent Tree Trimming and Maintenance
If your trees are shading your solar panels, you may need to trim branches or remove trees that block the direct sunlight. In extreme cases, you may need to remove or relocate trees that are heavily blocking sunlight to your solar panels.
It’s recommended that you trim tree branches and reassess the shading annually to ensure your system remains efficient. Additionally, it’s important to regularly check your solar panels for debris, such as leaves and branches that can affect solar panel performance. This is especially important after storms.
Roof and Panel Placement
Before installing your solar panel system, consider your roof orientation. If your roof is shaded or not ideally oriented, solar panels can be installed using a ground-mounted system that is placed on an area of your property that has less tree cover and shading and more optimal sunlight exposure.
Use Smart Solar Technology
Utilizing smart solar technology is also helpful in maximizing your system’s efficiency.
Microinverters allow each panel to operate independently, that way if one panel is shaded, it won’t affect the performance of the other panels. This can optimize the overall energy output of your system. If you have some shading on your property, this may be a great option for you!
Optimizers are another form of solar technology that work at the panel level to maximize energy production, especially in areas that are partially shaded.
Work with a Professional Solar Company
Lastly, it’s important to work with a professional solar company that specializes in solar system design, installation, and maintenance. They’ll assess your roof, property, trees, and shading and suggest the best panel placement for you.
