Perth Solar Warehouse

The researched choice for solar, battery and EV Charging.

Diversifying from an energy service operation [2011], McKercher Corporation began selling turnkey solar photovoltaic systems using a digital shop front to supply warehouse direct German-made options for customers seeking a superior grade of available technology. Traditional sales formats had excessive premiums built into the costs, limiting a wider uptake of high-grade solar products. In 2013, the Perth Solar Warehouse name was adopted to assist with greater commercialisation to the local Perth market. A popular name on Western Australia’s solar landscape, Perth Solar Warehouse remains the original ‘Perth Solar’ business customers have trusted, spanning two decades and backed by one of the most established local electrical contracting companies, McKercher Corporation.

The intention behind Perth Solar Warehouse was always to provide unparalleled quality and service to a geographically specific customer base. The theory was simple: if customers had a genuinely great experience with a prominent local solar company, why wouldn’t they share such a positive experience with friends and family for similar advantageous outcomes? Achieving a successfully organic, evergreen approach would eliminate and remove traditionally expensive sales and marketing costs. With a simplified overhead structure and an easily accessible digital shop front, customers could research in their own time while purchasing the finest solar products at competitive prices. More importantly, from an established company their family and friends also trust.
