Reducing size of mature maples
We have a perfect roof for solar panels facing directly south, however we have two attractive maples (a Norway and a Sugar) side by side in front of the house blocking the sun. Our contractor tells us they block too much for solar power to be viable.
We want to keep the trees as they limit sun coming in the south windows in summer and let it through in winter when we want it. Can we prune these trees back substantially enough to make solar work? Say 33% all dimensions including height? What is the most they can be trimmed without destroying the tree?
