People often cut down a few trees to make solar work on their roofs. (Read our blog article on the environmental implications of that decision.) The owners of this Boxborough home installed solar knowing they would later remove the tree creating the shade you see in this photo. To make solar pay for itself in a reasonable time frame, we recommend full sun on your roof from 9 AM to 3 PM.
