Identify shade sources
Trees, chimneys, neighboring structures, dormers and roof features may cast shade at different times of the year. A design should make its shade assumptions clear.
Panel-level electronics
Microinverters optimize conversion at the module level and may help manage varied panel conditions. They do not make shade disappear or guarantee a specific production outcome.
Plan for changes
Consider tree growth, maintenance, roof layout and practical access before approving a design. Ask how the production estimate accounts for current conditions.
