As more DFW homeowners install solar panels, landscape design needs to account for a factor that didn't previously matter as much: how trees and other tall plantings might eventually affect a roof's solar exposure over time.

Why Tree Placement Matters More With Solar Panels

A tree planted today at a modest size can, over years or decades, grow tall enough to cast shade across a portion of a roof's solar array, gradually reducing the system's energy production even if it wasn't an issue at the time of planting.

Planning for a Tree's Mature Height and Canopy Spread

When designing a landscape for a home with solar panels, it's worth mapping out where a tree's mature canopy will eventually reach relative to the panels' position, rather than only considering the tree's current size at planting.

Choosing Lower-Growing Species Near Solar-Facing Rooflines

For areas of the yard positioned to eventually shade a solar array, selecting species with a naturally lower mature height, or ones positioned further from the home, helps avoid future conflicts between landscaping and solar performance.

Balancing Shade Benefits With Solar Considerations

Trees do offer valuable shade benefits for cooling a home and reducing landscape water needs, so the goal isn't avoiding trees altogether, but rather being strategic about placement so shade benefits and solar performance don't work against each other.

Considering South and West-Facing Exposure

Since solar arrays are often positioned to maximize south or west-facing sun exposure, landscape design should pay particular attention to plantings on these sides of the home, where tree growth is more likely to eventually affect panel performance.

Working With Existing Solar Installations

For homes where solar panels are already installed and existing landscaping is a known or anticipated shading concern, a landscape design review can help identify problem plantings and suggest either pruning strategies or replacement with lower-growing alternatives.

Coordinating With Your Solar Provider's Recommendations

Many solar installation companies provide shade analysis as part of the initial system design, and incorporating this information into landscape planning helps ensure the two systems work together effectively rather than in conflict.

A Thoughtful Balance Between Landscape and Energy Goals

With some upfront planning, it's entirely possible to have both an attractive, tree-shaded landscape and a well-performing solar installation, provided the placement and species selection account for how the property will look and function years down the road.
