All solar panels are certainly not created equal, but the differences are much more significant than style or slight variations in energy efficiency. In this post, we will look at the Solaria PowerXT 320 Watt 320R-PX and what sets it apart from other industry products.
Solaria uses a patented cell cutting and module assembly method to create a panel design with less inactive space between solar cells than conventional solar panels, thus allowing the Power XT 320 Watt 320R-PX to optimize the entire panel surface to generate energy.
Solaria PowerXT solar cell modules have achieved more than 19% efficiency, compared to conventional modules, which most often range between 15% to 17% efficiency.
Solaria uses a ribbon-less interconnection method to connect and overlay cells in an energy-efficient shingle formation which allows more cells to be placed in each model and which does not use bus bars (components that can cover as much as 3.5% of the panel surface and significantly reduce energy production).
This ensures maximum energy output per square meter. 320 Watt 320R-PX panels are created with a patented sub-string assembly method that avoids the inflexibility and durability issues of soldered cells. Solder-less interconnected cells are considered far more durable than those that are soldered in a module.
Over time, the more durable high output solar panels can create exponential savings for your customers even with variable sunlight and unpredictable seasonal weather changes.
Shading performance promotes whole-home efficiency but is often overlooked. On the PowerXT, parallel connections between high-density solar cell substrings limit shading loss, a significant contributor to low energy production.
The PowerXT panel has fewer failure points than other products, but despite its high performance, Solaria offers an industry-leading 25-year linear power warranty, helping your clients rest assured that their investment is protected.
PowerXT modules are certified as UL 1703 with a Type 1 Fire Rating. Additionally, they and an IEC 61215/61730 certification. All PowerXT products appear on the California Energy Commission’s “Go Solar California” website for SB-1 compliant products.
