Canadian Solar has launched its next generation ‘ResidentialAC’ system less than six-months after the initial launch. The upgraded system combines the 250W PV module with its next generation microinverter while maintaining a standard 25-year system performance warranty.

Problem

Until now, PV system installers had to make use of first generation micro inverter technology. The company claims installers, homeowners and investors will benefit from fewer repairs, safety advantages of not working on high voltage DC electricity, and faster installations with lower labor and material costs.

Solution

Canadian Solar's ResidentialAC system comes with a 25-year long microinverter reliability to match Canadian Solar's module warranty by eliminating the key life limiting components in the current first generation of AC microinverters. The company said that the system is available in a 250W power rating format, up from 215W when launched last year and that the microinverter can be used with higher power class modules up to 300W and operates in high temperature environments above 65(o)C. Homeowners and investors will also benefit from faster ROI in using higher power class modules in addition to more flexible roof layouts that can accommodate portrait and landscape module orientations that optimize roof space usage.

Applications

Available in a sleek black frame, the module is designed specifically for home and business solar installations.

Platform

Canadian Solar's ResidentialAC system also includes monitoring software, allowing customers module-level tracking of solar panel performance to optimize the system's solar energy production.

Availability

January 2013 onwards.
