People move more frequently now than ever before, but that shouldn't impact your solar decision. A solar system can save you money today and even pay for itself in just a few years. Even if you move before your solar investment is completely paid off, the cost would likely be returned in added value to your home.
Plus, your home will most likely sell faster. Who doesn't want a home with a guaranteed low electric bill? System warranties are even transferable one time to a new owner.
