Economics of Solar Panels
AZOM.Com reports solar panels on your roof will cost more than you save on electricity before the panels have to be replaced. However, the panels will reduce your carbon footprint and conserve energy. Solar, wind, wave and tidal power, represent energy sources that could underpin a sustainable energy policy by minimizing our reliance on fossil fuels and at the same time reducing carbon dioxide and other pollutant emissions. The amount of electricity that can be saved over the lifetime of a PV panel is about 2000 kWh per square metre for thin film modules, with an expected life of 20 years, single-crystalline silicon devices with an anticipated lifespan of 25 years fare better producing 4400 kWh per square metre, according to Giacomo Bizzarri of the University of Ferrara and Gianluca Morini of the University of Bologna.
