32 panels installed July, 2007 with full SOUTHERN EXPOSURE-my 2-story house 3300 sq.ft. uses A/C, etc. WITHOUT ANY ELECTRICITY BILL. Monthly rebates for "sun collection" over 5 years CUT TOTAL PANEL & INSTALL PRICE BY ONE-HALF; plus I have no monthly utility bill and get another rebate check each year’s end - MOHR POWER IS SUPERIOR TO THE COMPETITION because NOT all systems are comparable- MOHR achieves MORE THAN WAS PROMISED- love you guys!
