The initial investment for solar panels may seem with high front-end overhead to be later offset by keeping the property long enough for it to pay off through the long-term cost savings of electricity. In the United States, there are many rebates and tax incentives that you can take advantage of to assist in offsetting the large front end costs for solar panel systems. Most power companies will offer a rebate for solar panel systems along with other federal program incentives. If you are planning to reside in your home for a long period of time a solar panel system will certainly pay for itself typically within about 5-8 years.
A positive certainty to your investment in solar panels is that once you purchase a system, your costs are basically fixed. In other words your cost for those panels is set as you have already paid for that energy by already purchasing the solar panels. The cost of electricity will continue to rise and significant increases are common as most consumers already realize. At some point you will end up paying less than non-solar users for the same amount of energy. How long it takes before you are paying less depends on how much your panels cost and how much you would have been paying if you continued to purchase electricity from your power company.
A ball park figure to install solar power to supply your home would roughly cost approximately $20,000 or about $10 per watt. If you are not up to this investment just yet, you can also use solar power to reduce costs for smaller household functions as well. For example you could purchase and install a small solar powered system that could power your computer and a couple of other small household appliances for about $800-$1,000.
