Membrane Cycle life can be variable as there are many factors outside of our control that make it very difficult to give a cast iron guarantee. However, we have been in the Solar business for a long time now – over 10 years now – so taking account of these variables we give a warranty guide as detailed in the descriptions for each grade. See our White Paper: “A Guide for Optimising Membrane Performance”.
