The team at PSW were extremely helpful in choosing a solar system. No pressure to purchase at all. We purchased a 6.6 kw system Jinko Black panels 390W with a Huawei inverter. Once we decided on a system they were very accomodating with an install date around my work roster. The guys that did the install did a great job very neat and no mess left behind on completion. The system is functioning great and no problems so far after a month of operation. Can highly recommend PSW to any person seeking a solar installation.
