can i file a lien against a solar company?

I AM A HOMEOWNER WHO HAD A SOLAR SYSTEM INSTALLED 2 YEARS AGO AND HAVE MANY TIMES ASKED (BY LETTER) TO HAVE THE SYSTEM REMOVED. THE COMPANY DEACTIVATED MY SYSTEM DUE TO NON PAYMENT. i HAVE SENT LETTERS TO HAVE SOMEONE CHECK AND NO ONE HAS GOT BACK TO ME. I HAVE THE PANELS ON MY ROOF WITH NO SERVICE. I INVOICED THEM FOR HAVING THE PANELS ON MY ROOF AND NO RESPONSE. I WANT THE SYSTEM ACTIVATED AND SOMEONE CHECK IT TO BE SURE IT IS WORKING. I HAD TWO INVERTERS REPLACED THE SAME YEAR IT WAS INSTALLED. I HAVE HAD ANOTHER COMPANY COME OUT TO CHECK THE SYSTEM AND WAS TOLD THAT IT WAS NOT PRODUCING THE KWH IT WAS DESIGNED FOR. DON'T KNOW WHAT TO DO. ROBERT SOTO RJSOTO45@YAHOO.COM 808-357-7371
