Pave Guard Technologies,® Inc. has combined subsurface heating with solar energy to present a system that will eliminate snow and ice from forming on pavement while serving as an alternative energy source. Solar panels silently convert light into electricity. They have no moving parts, require little maintenance and are designed to last for many years. Photovoltaic solar panels work best in direct sunlight, but they also work well even on cloudy days. Solar panels can be used to supply a substantial proportion of the electrical needs of typical households. They can be mounted on the roof or on the ground and connected to the local electric utility or stand alone (not connected to the utility), either supplying all the power directly to the home or pumping the excess back to the utility. Apart from reducing your electricity bill, home owners can often sell any surplus electricity directly back to the utility at an attractive rate.
