What is the cost of a solar-metal roof compared to other types of solar technologies?
A solar-metal roof is almost always the lowest life cycle cost solar energy system. A solar-metal roof can cost anywhere from a few dollars per square foot of roof to $20 per square foot. This is compared to solar PV systems that cost around $100 per square foot and solar hot water systems that cost around $50 per square foot. There are several factors that affect the cost of a solar metal roof. For example, if you require a new roof, or a reroof, the cost of the roof may already be included in your budget. In that case, the cost of the solar components (fans, ducts, controls) may only be a few dollars per square foot. Another factor affecting solar roof cost is the Federal and state tax credits available for commercial solar projects. These credits can cut the after-tax cost in half, or more, depending on your state incentives and corporate tax rate. Even non-profit and government organizations can get the benefits of tax credits if the solar roof is purchased by a commercial organiza
