Generally, the return on investment for a solar system takes about 10 years to pay for itself, but that can be sooner if you take advantage of energy tax credits. Some areas also have other incentives. See if you can get an Energy Star rebate.
You may have to wait a while to see the benefits, but the environment won’t. A solar water heater can cut your carbon dioxide emissions in half, preventing about 4,000 pounds of carbon dioxide from entering the atmosphere every year. That’s like keeping your car parked in your garage for four months every year!
While gas and electric waters last between 10-14 years, the average life expectancy of a solar water heater is much longer - 20 years. Your green architect
