Long time partners of Newphire Building, Southern Energy Management (S.E.M.), did a fabulous job of installing the 8 kW solar array on my upper roof. It is a ballast mount system due to the installation over the EPDM on my flat roof. Definitely don't want penetrations at 1/4"/foot slope! SEM provided a monitoring system to assess use and production. It will be a super useful tool for me. I will be providing a link on my website so that others can see how my quest for net zero is going!
