Solar shading issues are hard for us to determine without seeing your property in person. Typically, unless there are tall trees in the SE to SW window of your site's location, tree shading should not be significant enough to prevent you from exploring solar options. A rule of thumb is to have no shading at least from 10AM to 3PM. Since the sun is higher in the horizon during the summer, tree shading usually provides more obstacles during the winter than in the summer. Solar Impact can provide a complete site analysis to determine the exact shading and impact that any trees will have on your solar electric system.
