  • Complete system documentation including maintenance schedule and log sheets.
  • System Size: 15kW


Ten years after its establishment The Green Building in Carlton (where Going Solar is located) has added more PV panels on the roof. This is a special PV system with some of the latest technologies.

Despite 60L’s limited rooftop space, Going Solar was able to design the system that would reach maximum production potential by mounting the system north facing, with modules both flat to the roof and on a 10-degree tilt. Enphase technology maximizes annual energy harvesting capability at this low inclination, while at the same time ensuring best daily performance despite early morning and late afternoon shade effects.

Going Solar recommended Enphase Microinverters because, unlike string inverters, they could decouple the panels from each other so that any shade from structural elements does not impact the entire system’s production capability.
