Cost and Expected Life Span of Solar Panels

Based upon prices these days, a typical single solar panel, with a rating of 100 watts, costs between $400 to $500, depending on its brand. However, the brand isn’t the only factor to be considered. When your system utilizes a large number of panels it is likely to be extremely costly. Nevertheless, modern solar panels generally have a life expectancy of 30 years or more. Keep this when deciding to add a solar system to your home knowing that you eventually will be using electricity free of charge.
