Answer: C - The price for solar components is expected to remain roughly the same. They do not benefit from the same price reductions over time that some products such as technology-related items do. This is largely due to the large amount of raw materials in solar components that vary little in cost. This fact drives the inclination to design and install solar thermal systems now rather than waiting, and to maintain the necessary size rather than to try to “cut corners” by reducing the square footage of the collectors.
