RENEWABLE ENERGY SYSTEM REGISTRY II

GLREA has conducted a second survey of renewable energy suppliers to identify the number and types of renewable systems currently selling in Michigan. To accomplish this task, GLREA again surveyed sixteen renewable energy suppliers that sell systems in Michigan. We asked the dealers to identify the quantity and size of the systems that they sold in the state in 2002.

Seven respondents (44%) completed this year's Renewable Energy System Survey. The information received indicates that the equipment types sold in Michigan in 2002 as shown on the following table:

2001 2001 2002 2002 2001/2002 2001/2002

Technology

Number sold

Total sq.ft./watts

Number sold Total sq.ft./watts Number
sold
Total sq.ft./watts
Solar (Air) 6 703 sq. ft. 1 450 sq. ft. 7 1,153 sq. ft.
Solar (Liquid) 5 376 sq. ft. 1 64 sq. ft. 6 440 sq. ft.
Solar (Pool) 28 9,080 sq. ft. 33 5360 sq. ft. 61 14,440 sq. ft.
Solar Electric (PV) 34 32,080 watts 12 5283 watts. 46 37,363 watts

Wind Electric

33

62.200 watts

2 1400 watts 35 63,600 watts


Based on the findings from the surveys the most common solar energy system application appears to be Solar Pool Heating, with Solar Electric systems a distant second.

It appears that fewer systems were installed last year than in 2001. The fact that there were fewer incentives for smaller renewable energy installations in 2002 than 2001 may have influenced this decline.

If you are a renewable energy technology dealer and would like to participate in future surveys, please let us know at info@glrea.org. Your input assists GLREA in our efforts to advance renewable energy in Michigan and may increase the state's ability to provide incentives.
