My purpose is always the same; tighten any loose nuts and bolts on our solar array and conduct a visual inspection of the roof itself.<\/p>\n<p>In the old days they called this type of activity \u201c<em>preventive maintenance<\/em>\u201d and I always find something that needs tightening or adjusting on the solar array. Nothing major, mind you, just a screw loose here and there which might cause a problem sometime down the road. A quarter or half turn with a 5\/8\u201d box end wrench or 5\/16\u201d hex key and all\u2019s right in Cog\u2019s solar universe.<\/p>\n<p>Loose screws and fittings are known structural vulnerabilities when generating power from sunlight. The constant heating and cooling of the aluminum frame, combined with high winds out here on the edge of the mountain, present minor challenges easily overcome if one is proactive and not afraid of heights.<\/p>\n<p>Well, not <strong>too<\/strong> afraid of heights. I admit to being a little queasy until I get my sea legs properly adjusted. Mrs. Cog, on the other hand, does not like me on the roof and lets me know her displeasure every fifteen minutes or so when she appears outside looking for blood and guts spilled from a fallen Cog. In truth I don\u2019t blame her for her concern. I\u2019m not as young as I once was and balance is no longer my strong suit.<span id=\"more-16174\"><\/span><\/p>\n<p>Once every nut and bolt has been hand checked\/tightened I turn my attention to the roof itself. I was a residential home builder back in the 70\u2019s and 80\u2019s and I\u2019m quite familiar with all the techniques used in home construction.<\/p>\n<p>\u2026click on the above link to read the rest of the article\u2026<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A FEW SCREWS LOOSE Twice a year, usually in the spring and fall, I haul out one of my extension ladders, fill my back pockets with various wrenches and screwdrivers, and venture up onto our log cabin roof.
