Should you wager the value of your installation only on module validation data?

When you’re STR Protected™, you won’t have to! Pictured at right is STR’s two-axis tracker in Tempe, AZ, USA – one of the sunniest places on earth. STR Scientists fielded modules with our key platform encapsulant formulations on this tracker in 1996 to evaluate their effectiveness at maintaining power output under the harshest of real-time, actual outdoor conditions. Our confidence is data-driven. Accept no substitutes.
