Why microinverters are the smarter way to power your home with solar energy
In short: Expert Ross Trethewey demonstrates the professional installation of solar panels using microinverters. This video explains why this specific technology is advantageous for residential arrays, ensuring that individual panel performance remains independent even when faced with shading or equipment malfunctions.
Solar panels generate DC power, which must be converted to AC power for home use. Unlike traditional systems, microinverters are attached directly to the aluminum racking system for each individual panel. This configuration allows every panel to operate independently, meaning the entire array continues to function efficiently even if a single panel is shaded or fails.
Before installation, a professional contractor should evaluate the roof to ensure it is a suitable candidate. An ideal roof is pitched between 30 and 40 degrees, faces south, and lacks obstructions like trees that cause shading. The installation process involves lagging and flashing stanchions into the roof structure, mounting the aluminum racking, wiring the microinverters to a trunk cable, and finally securing the panels.
