For the average solar shopper, that translates to around $61,093 in savings over 25 years. Your payback period depends on your electricity costs, system size, and how you pay for solar. Understanding what drives those differences. . For most homeowners in the U., it takes roughly 11 years to break even on a solar panel investment. For example, if your solar installation cost is $16,000 and the system helps you conserve $2,000 annually on energy bills, then your payback period will be around eight years (16,000/2,000 = 8). If you want to learn how to do the math yourself, read on.
