High Installation Costs, Limited Awareness, and Dependence on Government Incentives May Hinder Market Expansion

The market for solar thermal collectors is mostly constrained by high installation costs, little customer awareness, and reliance on government incentives. Home and business purchasers may be put off by the high initial cost of equipment and installation, and adoption may be slowed by ignorance about the advantages of the system. Uncertainty is increased by reliance on subsidies or governmental support, and regionally disparate regulatory frameworks may further restrict market growth. When taken as a whole, these elements impede broad deployment and impede market expansion.
