The DecoTech system comes with the panels, their interlocking frames, and the flashing. The system is purposely technology-agnostic so that it can be used with any type of inverter, module-level power electronics (MLPE), switches, energy management software, sensors, wiring, battery bank for power storage, or charge controller. This is very convenient and considerate of GAF, since they primarily specialize in roofing and do not provide any of the balance of system (BOS) components listed above. This means that you are free to design the remainder of your system however you choose so that it best fits your energy needs.
