Manufactured in compliance with the most stringent quality standards, Shell PV solar modules are designed to withstand the toughest environmental conditions and are characterized by their long service life.

Shell Solar Power Max Ultra modules are covered by a 25-year limited warranty on power output. Shell CIS solar modules (ST10 and ST20) are covered by a 10 year peak power warranty.

Shell Solar proprietary PowerMax technology optimizes the energy production of individual cells and solar modules for all types of environmental conditions. PowerMax process optimization includes a special refining technique for ingots, a clean room semiconductor grade production process and a multistage proprietary TOPS (Texture Optimized Pyramidal Surface) process. The TOPS process incorporates the formation of textured pyramids on the surface of the solar cell. These pyramids are then treated with special oxides to passivate the surface. TOPS maximizes photon absorption from direct and diffused light (typical under cloudy conditions). This means that light absorption is especially high, even at low light levels. Shell SolarPowerMax solar cells deliver maximum energy throughout the day.
