Abstract: . . .  medium-temperature collectors were responsible for approximately 5 percent (Table 15). Medium-temperature collector shipments in 2002 increased 129 percent from 2001, reversing the decline in shipments each year since 1995. High-temperature collectors used by utilities and non-utilities in experimental grid electricity programs represented less than 1 percent of total shipments (Figure 16).

The average price for total shipments decreased 2 percent, from $2.90 per square foot in 2001 to $2.85 per square foot in 2002. The value of low-temperature collectors, 95 percent of total shipments, decreased from $23.5 million in 2001 to $21.8 million in 2002, a decrease of 7 percent (Figure 17). The average price of low-temperature collectors decreased from $2.15 in 2001 to $1.97 in 2001. In contrast, while the value of medium-temperature collectors increased from $8.7 million to $11.4 million (a growth of 32 percent), the average price fell 43 percent to $18.63 per square foot. Shipments of flat plate collectors were responsible for the decline in average price of medium-temperature collectors, falling 47 percent. Fig. 17 16 Solar energy  . . .
