Gerretsen Properties Goes Solar!! We are extremely proud to announce that Gerretsen Properties is now in the process of adding rooftop solar panels to various property locations we manage.  The actual sites selected are/will be based on various criteria (for example: those with the best exposure to the sun). Below we welcome you to browse our online EMU (Energy Management Unit) data which is uploaded to our site in real-time!  In each location you can view the actual panel configuration as well as details and statistics with respect to the daily, weekly, monthly and lifetime production values. Please select a location below.   Helen Street, Kingston
