Solaria Solaria is unique in that it built what it considers to be the perfect residential mod- ule, the PowerXT, and offers it as is or as an inverter-integrated AC version. Solaria uses proprietary manufacturing to singulate its mono PERC cells into uniform strips that are then re-assembled into high-density PowerXT cells. The PowerXT comes in a pure black appearance and uses proprietary technology to eliminate bus bars, so there's no visible circuitry and fewer failure points.

Additionally, many of the other materi- als used in solar panels now also face duties as part of a 10 percent levy on about $200 billion worth of Chinese goods that went into effect in September. The tax on these imports was expected to rise to 25 percent on Jan. 1, 2019, adding additional burden even to U.S.-made solar modules. Finished solar panels require scores of components, ranging from aluminum framing to transformers, solar glass and power inverters. Solaria's CEO Suvi Sharma estimates that U.S. tariffs this year have increased the company's U.S. production costs by about 30 percent — an amount equal to the original U.S. solar panel import duty. As a consequence of the tariffs, Solaria abandoned its plans of boosting production this year at its plant in Fremont, Calif. Due to capital expendi- tures imposed by the tariffs, the compa- ny was unable to expand its workforce in the U.S. as planned. LG does not manufacture cells or modules in China, but it too was impacted by the tariffs in 2018. In response to this the company is commit- ted to establishing a 500-MW produc- tion facility in Huntsville, Ala. Although this was in the works prior to the announcement of the tariffs, due to the strong market demand from the U.S. and LG's desire to be closer to its cus- tomers, the tariffs certainly accelerated the process. The f irst modules manufac- tured in Huntsville will be rolling out in Q1 this year. Module Buyer's Guide
