Every day, your solar system will generate free, renewable energy and save you money on electricity costs. When solar companies in Georgia talk about the “payback period,” they are referring to the number of years your solar panels will have to generate electricity before your savings surpasses your initial investment (the cost of a solar installation). The payback period is determined not only by the cost of installation but also the price of electricity in the future which of course we do not know with certainty. Assuming that future increases in electricity prices will not exceed past price increases, the average solar system installation has a payback period of 8-12 years in Georgia.
