Solar panels can be installed as a ground-mounted system, or they can be installed on a southern-facing roof. A solar system has a very long life of 30 - 40 years. At Heavenly Winds, we invite people to come and visit our energy-efficient home and see actual renewable energy systems installed and working. We have many satisfied customers who have purchased pv solar systems. We would be happy to show you how affordable a renewable energy system can be. We are a licensed, certified solar dealer and can show you several different brands of solar panels - even solar panels made in the U.S.A.
