Path-Q Solar

How can I estimate whether tree removal would create enough additional solar production to justify its expense?

Answer

Compare the incremental value of the energy gained after removal with the full cost and consequences of removal. Use a site-specific shade model to estimate production with and without the tree, then account for removal, disposal, future maintenance, financing, energy-value assumptions, and any restrictions or replacement obligations.

Key points

  • Use incremental production, not the entire array's production, as the benefit of removal.
  • Value the additional energy using the applicable bill and export treatment rather than a generic electricity price.
  • Include nonfinancial factors such as privacy, habitat, storm risk, and the tree's condition.

What it depends on

  • Tree-specific shading before and after removal
  • Removal, stump, disposal, restoration, and possible replacement costs
  • Electricity use, rate structure, export treatment, and expected system life

Risks and trade-offs

  • Production estimates can be overstated if future shade or system losses are ignored.
  • Removal may require owner consent, permits, or compliance with local restrictions.
  • A smaller or differently placed array may be preferable if removal has high environmental or financial cost.

Information you may need

  • Professional shade simulations with and without removal
  • Written removal and restoration estimates
  • Applicable ownership, permit, tree-protection, and replacement requirements

What to do next

Build a side-by-side comparison of removal, pruning, alternate placement, and no action using documented production and cost assumptions.
