Helios Solar Works (heliossolarworks.com) offers its SolSimple AC module with a factory-integrated Exeltech microinverter (and no exposed DC wiring). These 60-cell monocrystalline modules are rated at a maximum of 216 watts at 120 VAC. The CEC inverter efficiency is 94.5%. These modules, manufactured in Milwaukee, Wisconsin, can be specified to be 100% “made in the USA,” and come with a 25-year performance and a 10-year workmanship warranty.
Module-level monitoring is available via the HelioSentry data interface. One HelioSentry can accommodate up to 20 modules. Options include the ability to collect additional data, such as irradiance, temperature (module and ambient), and household electricity consumption, from supplementary sensors.
