This report was created and published by the Massachusetts Clean Energy Center (MassCEC). It provides a preliminary analysis of the monitoring that had been done to judge the efficiency of select water heating systems which were installed under the Commonwealth Solar Hot Water Program.
Forty systems were brought into the monitoring program but only 30 were online and monitored at the stage when these results were published. It typically cost around $1,200 to install and make use of a monitoring system for each of the solar thermal systems installed. The researchers found that the actual monitored energy production of the systems were within the range of 80%-110% of their original estimates.
