The bottom line on solar panel systems is that they will save you money, and pay for themselves a few times over. They provide free electricity for the life of the system, and can greatly offset or eliminate your electricity bill. Compare that to other investments of that size, such as purchasing a car. You can pay $20,000 for a nice new car, and it will greatly depreciate over time, as well as cost you thousands per year to operate and maintain. That same $20,000 can buy you a large solar panel array and system, provide most of the electricity for a medium sized house, and save you thousands of dollars of its lifetime. You will easily make that $20,000 back in savings, and depending on energy costs in the future, use the additional savings to buy a new car. That’s just a smart investment.
