<div>I wanted to share a recent interesting experience with the group.</div><div dir="auto"><br></div><div dir="auto">I
received a call from a client regarding module discoloration on a few
modules on a ground mounted array. I asked her if the color discrepancy
changed based on angle of observation or sun position and she said that
it did not.</div><div dir="auto"><br></div><div dir="auto">Arriving on
site, the discoloration was apparent. It turns out that she was
regularly watering some plants near the array and has very iron heavy
hard water. There was a layer of mineral deposits on the glass from the
over spray. A slight thumb rubbing removed the layer and the
discoloration.</div><div dir="auto"><br></div><div dir="auto">This was a new one for me. I am attaching a picture.</div><div dir="auto"><br></div><div dir="auto">In my climate we rarely have dirty module issues. What would be the best product for cleaning the glass safely?</div><div><br></div>
