KW DC

        A 65 kW grid-tied system that HNU installed at Molokai Education Center. A big part of the project was to provide 30 hours of field training to 5 MEC interns. The interns were trained to self-perform the installation of solar racking equipment, DC wiring, modules, inverter, etc. under direct supervision of a qualified HNU team.

In parallel, the interns obtained 15 hours of classroom training to learn about common industry practices involved in moving a typical solar PV project from project development to commissioning, under current market and policy landscape. The project was ahead of schedule thanks to the quick learning capabilities, aptitude and hard work of all interns and crew involved.
